Abstract:

The objective of this study is to find out and explain the destructive fishing practices occurred in Taka Bonerate National Park area and the factors that caused it. Data retrieval was conducted with in-depth interview techniques, literature studies and documents. The results showed that destructive fishing practices were still prevalent in the Taka Bonerate National Park area, both using chemicals (cyanide) and those using explosives (bombs) in fishing activities. The conclusions from this study are that fisheries destructive activities are generally not carried out individually but in groups, namely 3-4 people led by a captain. There are several contributing factors to the proliferation of destructive fishing practices in the small islands of Taka Bonerate National Park. Where they are still under guarded, and the conflicts of authority among the Taka Bonerate National Park management authorities, conflicts between fishermen, and availability of bombs and cyanides raw materials. The other are strong position of retainer and weak position of mustard in patron client relations between punggawa-sawi. The last factor but not least, that there are markets for them to sell the bombs and cyanide fishing.

Abstract:

Abstract, The criminal law policy in dealing with destructive fishing is currently primum remedium. However, in its development the criminal law policy in overcoming destructive fishing experiences several obstacles and is not yet in line with the concept of sustainable development. Considering that sustainable development is one of the principles in fisheries management, it is necessary to make adjustments between criminal law policies and sustainable development. Therefore this research aims to study and analyze the ideal criminal law policy in overcoming destructive fishing in the sustainable development regime. This research is a doctrinal law research using a statutory approach, analytical approach, conceptual approach, and case approach. The results showed that the ideal policy of criminal law in overcoming destructive fishing in sustainable development regimes is to make arrangements for sanctions actions that lead to social, economic improvement and repair damage to fish resources and their ecosystems due to destructive fishing practices. Sanctions for actions are more restorative, anticipatory, and educational so that they can reduce the degradation of fish resources and the environment. Thus, the balance between the use of fish resources and sustainable development can be realized. Keywords: Destructive Fishing, Criminal Law, Sustainable Development Intisari, Kebijakan hukum pidana dalam penanggulangan tindak pidana destructive fishing saat ini bersifat primum remedium. Namun dalam perkembangannya kebijakan hukum pidana dalam menanggulangi destructive fishing mengalami beberapa hambatan dan belum selaras dengan konsep pembangunan berkelanjutan. Mengingat pembangunan berkelanjutan merupakan salah satu asas dalam pengelolaan perikanan, maka perlu dilakukan penyesuaian antara kebijakan hukum pidana dengan pembangunan berkelanjutan. Oleh karena itu penelitian ini bertujuan untuk mengkaji dan menganalisis kebijakan ideal hukum pidana dalam penanggulangan destructive fishing pada rezim pembangunan berkelanjutan. Penelitian ini merupakan penelitian hukum doktrinal dengan menggunakan pendekatan perundang-undangan, pendekatan analitis, pendekatan konseptual, dan pendekatan kasus. Hasil penelitian menunjukkan bahwa kebijakan ideal hukum pidana dalam penanggulangan destructive fishing pada rezim pembangunan berkelanjutan yakni dengan melakukan pengaturan terhadap sanksi tindakan yang mengarah pada perbaikan sosial, ekonomi dan perbaikan kerusakan sumber daya ikan dan ekosistemnya akibat praktik destructive fishing. Sanksi tindakan lebih bersifat restoratif, antisipatif, dan mendidik sehingga dapat mengurangi degradasi sumber daya ikan dan lingkungan. Dengan demikian, keseimbangan antara pemanfaatan sumber daya ikan dan pembangunan berkelanjutan dapat terwujud. Kata Kunci: Destructive Fishing, Hukum Pidana, Pembangunan Berkelanjutan

Abstract:

Destructive fishing has the potential to reduce the sustainability of marine resources and the productivity of marine products which will have an impact on the welfare of fishermen. Various motives for destructive fishing include economic, social, cultural motives, and even ignorance that this action is against the law. Politeknik Kelautan dan Perikanan Sorong carries out community service as an effort to provide understanding regarding environmentally friendly fisheries through lectures and the practice of making environmentally friendly fishing gear. The activity lasted for 2 days, attended by 20 fishermen target partners of Saoka Village. The results of the practice in the form of environmentally friendly fishing gear are handed over to target partners for use in fishing operations.

Abstract:

Indonesia is a country consisting of many islands. This makes Indonesia rich in natural marine resources consisting of marine products such as fish and other marine animals. Catching fish by means of damage or (destructive fishing) using trawlers, fish bombs, fish anesthesia needs special attention in terms of law enforcement, to support the protection of marine ecosystems and enforcement of existing regulations. This study uses a qualitative method with a normative juridical approach. This research shows weaknesses in committing destructive fishing crimes. This is intended so that law enforcers can enforce according to the provisions of the statutory regulations that are willing, and seek additional personnel or carry out strategies so that they can carry out surveillance in the Indonesian sea from catching fish in destructive ways.

Abstract:

This paper draws from an ethnographic vignette of dynamite fishing in southeastern Tanzania. I consider the utility of participant observation as a method for examining ecologically destructive practices, especially in contexts where such activities are illegal or prohibited by conservation regulations. I raise self-reflexive critiques, internal to my home discipline of anthropology, and discuss the methodological, ethical, and analytical challenges of attempting to document cases of dynamite fishing and other related phenomena of pressing environmental concern. Ultimately, I maintain that participant observation remains a valuable tool for documenting and explaining environmentally destructive activities.

Abstract:

Maritime piracy constitutes a major threat to global shipping and international trade. We argue that fishers turn to piracy to smooth expected income losses and to deter illegal foreign fishing fleets. Previous investigations have generally focused on cross-national determinants of the incidence of piracy in territorial waters. These investigations neglect piracy in international waters and ignore its spatial dependence, whereby pirate attacks cluster in certain locations due to neighborhood and spillover effects. We conduct a geographically disaggregated analysis using geo-referenced data of piracy and its covariates between 2005 and 2014. We demonstrate that the incidence of piracy in a particular location is associated with higher catch volumes from high-bycatch and habitat-destroying fishing, even when controlling for conditions in proximate coastal areas. We find, additionally, that illegal, unreported, and unregulated fishing exerts an especially pronounced effect on piracy. These findings highlight the need for anti-piracy solutions beyond enforcement to include the policing of fishing practices that are illegal or are perceived by local fishers in vulnerable coastal areas to be harmful to small-scale fishing economies.

Abstract:

SUMMARYPoverty may be an important influence on the exploitation of marine resources in tropical developing countries. A number of studies have hypothesized that destructive fishing gears, which can degrade habitat, capture high proportions of juvenile fish and ultimately lead to reduced yields, are primarily used by the poorer segments of society. However, few studies have empirically tested this relationship. This paper examines relationships between the use of destructive seine nets and thirteen socioeconomic conditions in communities adjacent to three peri-urban marine protected areas in east Africa. Fishers using destructive gears were younger, less likely to have capital invested in the fishery, had lower fortnightly expenditures and were poorer in two multivariate indices of material style of life. Based on the two multivariate material style of life indices, a binary logistic regression model classified whether fishers used destructive gears with almost 70% accuracy. These findings are broadly consistent with the literature on poverty traps, which are situations in which the poor are unable to mobilize the resources required to overcome low-income situations and consequently engage in behaviour that may reinforce their own poverty. Managers aiming to reduce destructive gear use may need to partner with civil society and donors to help break poverty traps.

Abstract:

Characteristics, impacts and economic costs and benefits of blast fishing have been little investigated and they were therefore studied in Indonesia, at the scale of individual fishing households and of Indonesian society as a whole. Although illegal and highly destructive to coral reefs, blast fishing provides income and fish to a vast number of coastal fishers who claim that they have no alternative to make a living. Crew members in small-, medium- and large-scale blast fishing operations earned net incomes per month of US$55, 146 and 197 respectively. Boat owners in the same types of operations earned US$55, 393 and 1100 respectively. These incomes were comparable to the highest incomes in the conventional coastal fisheries. At the individual household level, the differences between the three types of operations show clear incentives for scale enlargement. The cost-benefit balance at the society level was calculated with an economic model. This analysis showed a net loss after 20 years of blast fishing of US$306 800 per km2 of coral reef where there is a high potential value of tourism and coastal protection, and US$33 900 per km2 of coral reef where there is a low potential value. The main quantifiable costs are through loss of the coastal protection function, foregone benefits of tourism, and foregone benefits of non-destructive fisheries. The economic costs to society are four times higher than the total net private benefits from blast fishing in areas with high potential value of tourism and coastal protection. This analysis of characteristics, impact and economics of blast fishing should help to raise the political will to ban blast fishing from Indonesian waters. Moreover, it allows for an evaluation of possible management solutions, taking into account their costs and the socio-economic framework that caused coastal fishers to start using explosives.

Abstract:

The present study on fishing technique using sutijal (purse net) in the Chalan Beel was conducted for a period of 3 years from July 2011 to June 2014. Net description, operation details and catch composition were studied through field survey in different parts of studied wetland. Three different categories of sutijal were recorded. Catch composition revealed that all types of aquatic organisms are being caught by this net. Benefit-cost ratio of studied fishing net was also calculated. Frequent fishing by this net, especially in streams of remote areas of the Chalan Beel resulting in decline of fish species and abundance. Appropriate management steps are recommended to get rid of this destructive fishing gear.

Abstract:

Marine communities face anthropogenic pressures that degrade ecosystems. Because underwater soundscapes carry information about habitat quality, we explored whether destructive impacts of fishing could be evaluated via the soundscape. Maerl beds are recognized as biodiversity hotspots and they experience major worldwide degradation owing to fishing. We collected field acoustic recordings in maerl beds exposed to different fishing practices. We found that unfished maerl beds were threefold louder and exhibited sound frequencies more diversified than those recorded in fished maerl beds. Analyses of associated fauna samples indicated that snapping shrimps provided a major contribution to the maerl bed soundscape. Moreover, sea urchins and squat lobsters most likely contributed to differences between the soundscapes of unfished and fished maerl beds. Our results supported the idea that the soundscape can provide valuable information on maerl bed ecosystem health related to fishing activity.

Abstract:

SUMMARYIn marine environments, charismatic or economically valued taxa have been used as flagships to garner local support or international funds for the establishment and management of marine protected areas (MPAs). Seahorses (Hippocampus spp.) are frequently used as flagship species to help engender support for the creation of small community-managed no-take MPAs in the central Philippines. It is thus vital to determine whether such MPAs actually have an effect on seahorse abundance, reproductive status and size. A survey of seahorses inside and immediately adjacent to eight MPAs, and in four distant unprotected fishing areas, showed these MPAs had no significant effect on seahorse densities; although densities in and near MPAs were higher than in the distant fished sites, seahorse densities did not change over time. Seahorse size did show a marginal reserve effect, with slightly larger seahorses being found inside MPAs as compared to the distant unprotected fishing areas, but, in general, MPAs had little impact on seahorse size. Although MPAs may eliminate local fishing pressure, they may not reduce other threats such as pollution or destructive fishing outside the reserves. Other recovery tools, such as ecosystem-based management, habitat restoration and limits on destructive fishing outside of MPAs, may be necessary to rebuild seahorse populations. The effects of MPAs depend on species, as well as conditions outside the reserve boundaries. MPA management objectives must thus be clearly and realistically articulated to the communities, especially if support for an MPA was derived at least partly to conserve a particular flagship species.

Abstract:

At present, corruption in the fishing sector has become a severe threat to the effectiveness of marine resource management. However, corruption activities that occur in fishing communities are still rarely revealed to the public due to the complexity and lack of researchers who are interested in learning them. The research aims to understand the behavior of the fish-bomb fishermen in Barang Lompo Island, South Sulawesi, in order to arrange suitable policy and program choice for reducing of using fish bombs in fishing activity. This research is conducted by a qualitative approach and ethnography method (participation observation) as well in a time series since 1999. The result showed that the corruption behaviors among the Barang Lompo fishermen are caused by several factors, i.e., aggressive culture, poverty, cultural burden and cultural pride, and consumerism. Corruption, in this case, makes a fishing business more efficient, with short working time indicators, and catches a lot.

Abstract:

Damage to coral reefs is generally caused by destructive fishing activities, they were the usega of explosives, cyanide toxic materials, coral mining for building materials, anchor boat anchors, and the results of sedimentation. Efforts to speed up the process of coral reef recovery, several methods of rehabilitation that can be done include coral transplantation and sinking of artificial reefs. The artificial reef is an alternative to reduce the pressure caused by fishing and destruction of natural coral reefs through the creation of new productive fishing grounds. The purpose of this study was to determine the relationship of water parameters (physical oceanography) for biota around artificial reefs based on Geographic Information Systems. The results of identification of oceanographic parameters in the waters of Damas Beach, Trenggalek Regency consist of: (a). depths range from 0-45 meters, (b). brightness ranges from 2 - 6 meters, (c). water temperature ranges from 25.18-29.59ºC, (d). water turbidity ranges from 0.3-4.32 NTU, (e). type of substrate base waters of Damas Beach fine black sand, (f). current speed ranges from 0.1-0.4 m/s, (h). the average wave height of Damas Beach in the morning, afternoon and evening is 5.6 cm, 8.14 cm and 6.2 cm, (i). the total suspended solid waters of Damas Beach range from 35-351 mg/L. The physical oceanographic parameters are still safe for the growth and development of biota in the waters of Damas Beach, Trenggalek Regency.

Abstract:

Destructive behavior to coral reef ecosystem should not exist if community realize the importance value of the existence of coral reefs, have adequate source for livelihood and an obedience to God Almighty. The purpose of this study is to analyze the influence of religious ritual performing (religiousness), social and economic conditions of society on destructive manner of community to coral reefs. The data collected are analyzed quantitatively using structural equation model (SEM) using the method of Partial Least Square (PLS). The result findings show that the destructive behavior of the community to coral reef is not influenced by the piety of the people in performing ritual worship. The more devout people in performing ritual worship behavior does not necessarily make them more friendly to the environment, particularly coral reef ecosystems. The destructive behavior of the community to coral reef is also not influenced by their social conditions. The higher level of community's education does not necessarily make them more concerned about the environment. The destructive behavior of community to coral reef is significantly influenced by the economic conditions of society. Communities with lower income levels tend to perform acts that damage the coral reefs such as coral mining and destructive fishing techniques in an effort to satisfy their economic needs.

Abstract:

Fish biodiversity on Hau (Bassac) river was investigated to assess the status of species composition and fishing by fishing gears during a year. Sampling was implemented monthly at the upper part (An Giang province), middle part (Can Tho City) and lower part (Soc Trang province) of Hau River using trawl net as main sampling gear. Additionally, fish composition was also recorded from four other most popular fishing gears including cast net, gill net, fixed net and hook operated in the study sites. Fish species composition was determined by fishing gears and their abundance (CPUE) was calculated only from the main sampling gear (trawl net). The results showed that a total of 176 fish species belonging to 16 orders and 49 families was recorded. Perciformes was the most abundant group with 51 species followed by Cypriniformes with 46 species. The number of fish species was decreasing from upper part to lower part. Trawl net was considered the most destructive gear as up to 145 fish species caught by this device, followed by gill net with 98 species, fixed net 75, cast net 57, and hooks 16 species. CPUE was very low ranging from 0.53 kg.ha−1 h−1 to 26.30 kg.ha−1 h−1. Higher CPUE was recorded at lower part in compared to upper part and middle part, and at dry season in compared to rainy season. Regulation on fishing gears, fishing ground and season should be taken into consideration to protect and conserve the resources.

Abstract:

The oriental driftnet fleet, which is responsible for the large-scale mortality of non-target species in the Pacific Ocean, has extended its range to include the South Atlantic Ocean. Relatively little is known about the areas of operation and impacts of driftnetting in the South Atlantic as yet, but it is emerging that driftnetting is equally devastating to the fauna of this ocean. This paper reviews the impact of the driftnet fishery on non-target species in the central South Atlantic Ocean. Several lines of evidence suggest that fishing effort is focused on Tristan da Cunha, apparently resulting in considerable mortality of rockhopper penguins Eudyptes chrysocome and other marine organisms. Britain should take steps to curb this destructive fishing technique in Tristan waters.

Abstract:

In a rural area, environmental degradation and poverty nexus focuses on the high-dependency of poor people to natural resources-based livelihood. Arguably, limited assets of poor people cause them to be unable to cope with natural resources degradation and to undertake sustainable practice in their livelihood activities. This study attempts to find the nexus between environmental degradation and poverty in the case of coral reef destruction in Indonesia by applying secondary research as a methodology. A sustainable livelihood framework is applied to analyze small-scale fisher people's vulnerability and capacity to destruct. This study finds that small-scale fisher-people have limited assets to cope with coral reef destruction; however, the same condition leads them to destruct coral reef by doing the destructive fishing practice. This condition causes them to be trapped in the downward spiral of environmental degradation and poverty. Moreover, small-scale fisher-people can overcome this problem by developing self-governance common pool resources to conserve coral reef and increase their livelihood sustainability.

Abstract:

Purpose – The purpose of this paper is to analyse how different policy perspectives or logics regarding industry organising affect network interaction, with particular focus on how the availability of resources is organised. Design/methodology/approach – To examine this, the authors compare two cases from the Norwegian seafood industry: in the pelagic industry, the main resource (mackerel) is caught at sea by fishing vessels and trade is restricted by an auction system, whereas in the salmon industry, the main resource (farmed salmon) is an industrial product produced at fish farms and there are no such restrictions. Findings – The results indicate that conditions under which resources are available to a network have strong effects on connected relationships: in the pelagic industry, interaction in the network becomes supplier-directed in an attempt to reduce the uncertainty created by unstable and restricted availability of resources, whereas in the salmon industry the interaction becomes customer directed as resource availability is stable and predictable. Here the actors can broaden the scope of interaction and they can direct their efforts to solve their customers’ problems, whereas this is difficult in the pelagic industry. The authors conclude that policy considerations play a major role in these effects. If the resource (fish) is seen as a commodity and the interaction is seen as a market mechanism, the policies designed to facilitate the exchange of resources will be beneficial for the actors directly involved, but may have unintended negative consequences for indirect relationships. Originality/value – For policy makers this implies that whenever developing an industrial policy there are strong reasons to look beyond the single transaction in order to create policies that are effective and/or beneficial for all involved and connected parties.

Abstract:

The aim of this study was to examine the status in fishing and fisheries industry among marine coastal communities of Kwale along Kenyan coast. In this study, we used a cross-sectional descriptive survey design to examine trends in fish and fisheries resources productivity and diversity and the types of fishing vessels and gears used by fishermen among marine Kwale communities. Quantitative data was collected using household survey questionnaires among fisherfolk households randomly selected from two subcounties in Kwale. Key informant interviews and focus group discussions were conducted on purposively sampled respondents to generate qualitative data to corroborate the quantitative survey data. Study established that fishing is still the principal source of livelihood, with 31% of people engaged in fishing as their main source of livelihood and being mainly artisanal fishers. There is a declining trend in fish productivity and diversity during the period 2014 to 2019. Out of all fisherfolks, 96.6% of fishers are commercial artisanal fishermen, selling their fish to different groups. The most preferred fishing vessel is wooden row boats (dhow) at 66.3% preference. There is a general decline in fish productivity within fishing grounds based on catches, indicated by 84.9% of the survey respondents. There is a general decline in fish abundance and diversity among coastal Kwale as indicated by 70.6% of respondents. Eleven (11) types of simple traditional fishing gears were identified, with majority (32%) of fishers preferring handline/hook (Mshipi) as their most preferred type of fishing gear. Destructive fishing gears such as spear guns are still in use despite the government regulations. This study concludes that fishing and fisheries resources among marine communities in Kwale of Kenyan coast is in a general declining trend in terms of productivity, abundance and diversity. This signals excess pressure on fishing resources, requiring immediate effective management strategies to contribute to sustainable marine ecosystems resources utilization. The study recommends enforcement of effective management strategies on fishing and fisheries resources through effective policy formulation and enforcement as well as awareness creation and a mind shift among communities towards alternative livelihood sources to reduce pressure on fish stock.

Abstract:

Understanding feedbacks between human and environmental health is critical for the millions who cope with recurrent illness and rely directly on natural resources for sustenance. Although studies have examined how environmental degradation exacerbates infectious disease, the effects of human health on our use of the environment remains unexplored. Human illness is often tacitly assumed to reduce human impacts on the environment. By this logic, ill people reduce the time and effort that they put into extractive livelihoods and, thereby, their impact on natural resources. We followed 303 households living on Lake Victoria, Kenya over four time points to examine how illness influenced fishing. Using fixed effect conditional logit models to control for individual-level and time-invariant factors, we analyzed the effect of illness on fishing effort and methods. Illness among individuals who listed fishing as their primary occupation affected their participation in fishing. However, among active fishers, we found limited evidence that illness reduced fishing effort. Instead, ill fishers shifted their fishing methods. When ill, fishers were more likely to use methods that were illegal, destructive, and concentrated in inshore areas but required less travel and energy. Ill fishers were also less likely to fish using legal methods that are physically demanding, require travel to deep waters, and are considered more sustainable. By altering the physical capacity and outlook of fishers, human illness shifted their effort, their engagement with natural resources, and the sustainability of their actions. These findings show a previously unexplored pathway through which poor human health may negatively impact the environment.

Abstract:

Historically, remote islands and marine resources have been free for those willing to venture into their areas. Until recent years, many such islands have been effectively managed by their remote locations and any native humans. But nowadays, under-use is turning into destructive over-fishing and plundering, because there is no surveillance. Many marine parks in South-east Asia are facing the same problems as Tubbataha (White, 1989; Arquiza, 1990). Sustainable management in these areas is a challenge, especially where there are no local authorities or communities to take immediate control.Field surveys at Tubbataha Reef in 1984 and 1989 have revealed a dramatic decline in the coral-reef quality from the incidence of dynamite fishing, the use of sodium cyanide for the aquarium and live-food fish trades, and the dropping of large anchors. Sea-turtles and seabirds are also endangered.Solutions in areas such as Tubbataha will require organization beyond the grasp of local residents in the islands, who have traditionally had little formal government. Although they are aware of the problem, they are faced with outsiders and intruders who do not respect their conservatism. National government and/or nongovernment organizations can play a role in management, while being careful not to alienate the positive force and management control of the local communities (White, 1988a). Such issues require sensitive planning and community-based approaches that are directed at education, organization, and the involvement and building of local responsibility.The management plan for Tubbataha Reef National Marine Park should have three thrusts and concomitant strategies: (1) to curtail immediate resource-destruction through the deployment of a team of educators, community organizers, and law-enforcement officers; (2) to articulate and implement a Park zonation plan which includes traditional fishing areas, sanctuaries, and buoys for anchoring; and (3) to implement a community development programme which will systematically integrate the adjacent fishing community into the Park management efforts and give the fishermen due responsibility in this process.

Abstract:

The present study was conducted to evaluate livelihood status of fishing community of the Punorvaba River under Dinajpur Sadar Upazila during the period from January to August, 2013. The livelihood status of fishermen were studied in terms of age structure, family size and type, occupation status, educational status, housing condition, drinking water facilities, sanitary facilities, health facilities, credit facilities and monthly income. It was found that most of the fishermen were belonged to the age groups of 36-45 years (40%), represented by 90% Muslim. The family size of fishing community is usually consisted of 5-7 members. Over 45% of the fishermen primarily engaged in fishing. Among them 50% was illiterate and 7% was SSC and above group. About 40% of the fishermen received health service from village doctors, 23% from upazila health complex and remaining 7% got health service from MBBS doctors. Some management strategies such as prohibition of catching brood fish, control of destructive gears, establishments of fish sanctuaries, release of fish fry have been suggested by the fishermen to stop the decreasing trend in the fish catch and to enhance fish production.

Abstract:

Abstract On the continental shelf, New Zealand bryozoans dominate ecologically-important three-dimensional benthic habitat providing structural complexity which hosts a wide variety of fauna, including economically valuable species (e.g. oysters and blue cod). The association between these species and bryozoan-dominated biogenic habitat commonly results in trawling damage to the benthos; eliminating pressure from destructive fishing practices could support bryozoan regrowth. In 2002, a voluntary fishing restriction was designated over part of one such bryozoan-dominated biogenic habitat, but the efficacy of this ban has not been assessed. Statutory marine protected areas have been proposed in the same area; they aim to achieve bryozoan protection and recovery. A comparison of the bryozoan fauna using benthic images from 2003 and 2019 from the Otago shelf, South Island, New Zealand/Te Waipounamu, Aotearoa shows that a 17-year voluntary fishing ban has been ineffective at increasing the cover and richness of bryozoan-dominated biogenic habitat on the Otago shelf. This study provides a baseline for future monitoring and develops useful metrics for recovery, while calling for further research on the biology and ecology of habitat-forming bryozoans.

Abstract:

Many industries apply pressure tanks for the storage of various types of liquids [1]. It can be toxic, chemically active liquids or food products. Storage conditions of these liquids can have a wide range of pressures and temperatures; therefore it is preferable to control the liquids levels from the outside of the tank. The most optimal solution in this case is the ultrasonic pulse time method [2-6], which is also widely used in robotics [7], fishing, shipping [8-9], archeology [10-11], non-destructive testing [12-17] and manometric method [18].

Upland rivers of hills of Uttarakhand are unique in its ecosystem and biodiversity. These waters possess various varieties of ornamental fishes. The present study focuses on Scope of ornamental fisheries in snow fed rivers of Uttarakhand, along with challenges and opportunities. Besides the availability of resources peoples are not that much aware of ornamental fisheries of this region and these resources are yet not developed. The use of destructive fishing methods, habitat destruction leads to diversity destruction of hills stream fishes. As theseresources does not comprise fisheries of commercial importance due to sparse biota and low thermal scale, slow growth and very low natural food availability So, Directorate of Cold Water Fisheries is actively working in the field of survey and brood stock management of ornamental fish resources of cold water. Four hundred live cold water fishes including exotic gold and koi carp are being maintained at DCFR main complex for study and breeding trials. The recreational activities by fisheries department like ranching, sport fisheries development and development of ornamental fisheries of this region can lead to socioeconomic upliftment of hilly people and development of cold water ornamental fisheries in the state.

Abstract:

Peristiwa overfishing semakin marak terjadi di beberapa wilayah perikanan Indonesia akibat penggunaan alat tangkap yang merusak (destruktif). Jika hal ini terus dilakukan, maka kelestarian sumberdaya dikhawatirkan akan semakin menurun. Maka dari itu dibutuhkan strategi agar usaha perikanan tangkap ramah lingkungan secara ekologi dengan cara mengidentifikasi alat tangkap berdasarkan kriteria Code of Conduct for Responsible Fisheries (CCRF). Tujuan dari penelitian ini adalah untuk menganalisis alat tangkap ramah lingkungan di PPI Celong berdasarkan Sembilan kriteria CCRF. Metode penelitian yang digunakan adalah deskriptif mengenai alat penangkapan ikan yang ramah lingkungan di Pangkalan Pendaratan Ikan (PPI) Celong pada bulan Desember 2017 dengan wawancara dan observasi lapangan. Responden diambil secara sensus sebanyak 121 orang. Hasil analisis ramah lingkungan menghasilkan skor 17,87 pada arad, 27,44 pada trammel net, dan 28,40 pada gill net. Kesimpulan yang diperoleh dari penelitian ini adalah status alat tangkap arad tidak ramah lingkungan, trammel net ramah lingkungan, dan gill netsangat ramah lingkungan. Arad termasuk dalam kategori tidak ramah lingkungan karena cara pengoperasiannya yang tidak selektif dan merusak dasar perairan. Overfishing are increasingly prevalent in some Indonesian fishery areas due to the use of destructive fishing gear. If it continues, then the sustainability of resources feared will decrease further. Therefore a strategy is needed for eco-friendly fishery business by identifying fishing gear based on the criteria of Code of Conduct for Responsible Fisheries (CCRF). The purpose of this research is to analyze the eco-friendly fishing gear at Celong Fishing gear based on Nine criteria of CCRF. The research method used is descriptive of eco-friendly fishing gear at Celong Fishing Port in December 2017 with interviews and observations. Respondents who were taken by census was 121 respondents. The results of eco-friendly analysis resulted in a score 17.87 for arad, 27.44 for trammel net, and 28.40 for gill net. The conclusions obtained from this research are arad status is not eco-friendly, trammel net is eco-friendly, and gill net is very eco-friendly. Arad is categorized as eco-unfriendly due to its non-selective way of operating and damaging the sea base.

Abstract:

Imported to adorn tanks of marine aquarium hobbyists, the trade in live corals poses a significant risk to species that concurrently face threats from rising global temperatures, pollution, and destructive fishing practices. To better understand the live coral trade, we employed a crime script framework to analyze the process by which corals are harvested in two of the world’s major exporting countries—Indonesia and Fiji. We demonstrate that coral harvesting and export are complex activities that require a specific set of skills and tools. As such, various intervention strategies are proposed to address illegal coral harvesting at different stages of the crime script.

AbstractThis article briefly reviews the current status of high seas bottom fishing and its impacts. It then traces the evolution of major intergovernmental discussions on these issues up to the 5th meeting of the UN Informal Consultative Process on Oceans and the Law of the Sea in June 2004, including the involvement of scientists and conservation organisations. Next, it highlights the four key arguments presented to date on the need for immediate action to curtail high seas bottom trawling: that it is largely unregulated and unsustainable, severely impacts deep-sea biodiversity, and is a highly destructive fishing technique. In addition, it draws attention to an important emerging argument on equity considerations. Rights and duties regarding conservation of sedentary species on the coastal state's continental margin beyond 200 nautical miles are also considered. A final section suggests possible solutions to the management impasse regarding high seas bottom trawl fisheries, covering the authority to regulate, the need for deep ocean assessment, strengthening the international community's stake in deep-sea conservation and some of the tools available.

Abstract:

Oil was discovered in large quantities in Nigeria in 1956 and exploration began in the same year. Before oil, agriculture and fishing had assured the Niger Delta people of a bright future. Since 1956, oil has been extracted from the Niger Delta with destructive consequences on the environment, bringing about environmental degradation and destruction of the people’s primary means of livelihood. Land and water were badly polluted, and the health of the people affected because of leaks from oil pipelines, gas flaring and acid rains. Several petitions and non-violent protests by Delta communities, women and youth against environmental destruction failed to receive attention. Rather, opposition to peaceful protests earned the people military invasions of their communities, clampdowns and jailings. The rise of militarism and terrorism in the Niger Delta was the result of the Federal Government and Oil Companies’ clampdown on non-violent protests for environmental justice in the Niger Delta. This paper discusses the history of oil exploration in the Niger Delta, oil laws, effects of oil exploration in the region, and the rise of militants and terrorists in the area. The paper uses the term, ‘environmental Justice’ to denote unfair treatment and destruction of the Delta environment resulting from oil exploration, non implementation and enforcement of environmental laws and regulations, and abuse of human rights.The paper suggests solutions for peace in the Niger Delta.

Abstract:

Tanguar Haor (TH) is considered one of the Ecologically Critical Areas (ECAs) of Bangladesh and is internationally recognized as RAMSAR wetland (2nd Ramsar site) known to provide multiple ecosystem services to the society. Nevertheless, multidimensional threats and stressors, the capacity to supply ESs, and the biodiversity of the TH significantly degrades and threatens this wetland’s conservation and sustainability. Although the legal framework promises the sustainable conservation of fisheries resources, information on the implementation scenarios of fisheries laws, regulations, and policies in the TH Ramsar are scant. By merging qualitative and quantitative data of primary and secondary sources, this research aimed to analyze the legal framework to check the effectiveness of regulations for non-conflicting fisheries resources and the sustainable conservation of the TH Ramsar. Primary empirical data were collected by employing Participatory Rural Appraisal (PRA) tools, i.e., 204 semi-structured questionnaire-based individual interviews with fishers, three focus group discussions, and 14 key informants’ interviews in three fishing villages in the TH. In contrast, secondary data was set by reviewing published literature and related official documents. Results showed that, due to weak enforcement with inadequate surveillance and poor implementation of the legal framework, there was a high non-compliance with fishing laws, rules, and policies. Destructive and prohibited fishing gears, e.g., the use of small mesh fine nylon nets (current jal), purse seine net (ber jal), and the harvesting during ban period-illicit catch were widespread in the study areas. In addition, catching undersized fish, fishing at the restricted areas (sanctuary area), and fishing during spawning seasons occur often. There is a crying need for a comprehensive legal and policy framework to contextualize the local context, ensure the proper implementation of the fishing laws and regulations, increase the managerial inefficiency of enforcing agencies, ensure livelihood support during the fishing ban, and afford good alternative income options are still significant issues for good governance in the Tanguar Haor ECA. Findings might help to identify the gaps and misunderstanding of the existing legal practice while submitting urgent attention to the need for drawing a comprehensive legal and policy framework (contextually modified according to the local context), taking initiatives and acting synchronously for proper implementation, and calling transdisciplinary collaboration and cooperation among the agencies that may ensure the non-conflicting use of the natural resources of the TH that can be also helpful for the better conservation of this Ramsar wetland.

Abstract:

Abstract Gillnets are one of the most widely used fishing gears, but there is limited knowledge about their habitat effects, partly due to the lack of methodology to quantify such effects. A stereo imaging method was identified and adapted to quantify the dynamic behaviour of gillnets in-situ. Two cameras took synchronized images of the gear from slightly different perspectives, allowing to estimate the distance from the observation unit to the gear such as in the human 3D vision. The sweeping motion on the seabed and the penetration into the sediment of the leadline of light and heavy commercial bottom gillnets deployed in sandy habitats in the Danish coastal plaice fishery were assessed. The direct physical disruption of the seabed was minimal as the leadline was not penetrating into the seabed. Direct damage to the benthos could however originate from the sweeping movements of the nets, which were found to be higher than usually estimated by experts, up to about 2 m. The sweeping movements were for the most part in the order of magnitude of 10 cm, and resulted in a total swept area per fishing operation lower than any of the hourly swept area estimated for active fishing gears. Whereas the general perception is that heavy gears are more destructive to the habitat, light nets were moving significantly more than heavy ones. The established methodology could be further applied to assess gear dynamic behaviour in situ of other static gears.

Abstract:

Bottom trap have been used widely by coastal communities in North Sulawesi to catch coral fishes, since it simple in design, cheaper and easy to manage with a small boat. Unfortunately, the fishing practice of the traditional trap is usually conducted in destructive way, where fishermen cover the gear with live coral to attract fishing target. Although the gear’s design has evolved over centuries, there is still potential for improving its catching efficiency and selectivity. An attempt to understand the fishing process of bottom trap should therefore be focused on bait and how its chemical composition, visual and physical properties may stimulate target species to attack the bait and captured. Addition of squid liver oil to the bait could increase the fishing power of bottom trap gear. But scientific information’s about its applications are not available yet. Therefore, the objective of this research was to study the effect of squid liver oil on bait of bottom trap toward the capture of coral fishes. This research was done in Bangka Strait North of Minahasa, based on experimental method. Six units of bottom trap (bamboo) were operated ten nights in collecting data; where tree units of them used scad mackerel bait that injected by squid liver oil, and tree other units just used scad mackerel bait without squid liver oil; and the capture data were analyzed by ttest. The catch was 117 fish in total consist of 2 genera; 74 fish was caught by scad mackerel bait with squid liver oil, and 43 fish was caught by bait without squid liver oil. Analysis of ttest show that t0= 8.908>t0.05; 5= 3.250; which means that the addition of squid liver oil on bait could increase the catch of bottom trap.
