Full textAbstract:
The prawn (Cryphiops caementarius) is the only resource in the Peruvian coastal rivers that supports a commercial fishery. Bioeconomic-fishing aspects are reported based on data (fishing, costs and income derived from fishing) acquired in situ monthly in four altitudinal strata (every 200 meters above sea level - masl) of the Majes-Camaná river during 2019. The catch per unit of effort (CPUE) was expressed in kg h-1, monthly income was estimated based on the average catch values, number of tasks and price of the resource. To evaluate the profitability of the activity of an average fisherman (by stratum), a cash flow based on income and expenses was executed under situations with a constant future, using economic profitability indicators such as the Net Present Value (NPV), Internal Rate of Return (IRR), Benefit-Cost ratio (B/C) and Discounted Payback Period (DPB). There was a predominance of the diving method, the catches (kg) and the fishing yield increased throughout the fishing period (April-December) with a maximum value of 4.8 kg h-1 (December - high strata). Investment costs per fisherman were low, roughly 1,000 soles. The sale price increases with altitude, decreasing over the course of the year depending on the availability of the resource; the monthly income per fisherman varied from 964 soles (April - low stratum) to 6,760 soles (December - high stratum). The economic simulation model showed that the income exceeded the costs of the fishing activity from the first year of activity in all the altitudinal strata, the economic profitability indicators showed high profitability for the activity.

Full textAbstract:
The present study was concerned to assess the present status of biodiversity in the Bhairab river, Jessore with its conservation measures. The study was based on primary observations, questionnaire interviews with 50 fishers, focus group discussions with river bank community members and cross-check interviews with key informants. The study was conducted for a period four months from May to August, 2016. The objective of the study was to assess the fish biodiversity in the Bhairab river, understand the existing fishing practices of the river and to identify proper management strategies for the conservation of fish biodiversity. Results of the study revealed that three kinds of fishers were engaged in the Bhairab river namely, professional fishers; seasonal fishers and subsistence fishers. Seven types of fishing gears like seine net, gill net, cast net, push net, lift net, trap and hook and line were operated to fish by the fishers during the survey. A total of 39 species of fish were identified in the catches of the Bhairab River. There are degraded ecosystems and declining biodiversity have found during the study. According to survey, fishing pressure and over fishing were responsible for almost 38% loss and pollution and siltation caused about 27% loss of ecosystem. Around 21% and 14% loss of ecosystem were caused by urbanization and human encroachment, and the recreational activities respectively. These have been created a great impact on river ecology. As a result, the water quality is deteriorating day by day and the availability of fish species and other aquatic biodiversity is decreasing gradually. During the survey, 20 species was found at a risk of being endangered. From the survey, it was found that the overexploitation of fish was responsible for the 40% losses of biodiversity in the Bhairab River and water pollution caused 35% loss of biodiversity. Henceforth, river course change and habitat degradation resulted in 15% and 10% loss of biodiversity of the river respectively. This study was identified possible ways to achieve a rich fish biodiversity in the Bhairab River with social, economic and environmental aspects. The specific recommendations are included community based fisheries management, establishment of sanctuary, control of pollution, maintenance of fishing gears and the implementation of fish act for conservation of fish biodiversity of the Bhairab River.Asian J.

Full textAbstract:
Small-scale fisheries (SSF) is a local and community-based activity that can be traced back to ancient times, and thus, closely related to the history of humankind. However, large-scale fisheries have grown tremendously, approaching an industrial sector in the last century, due to their socio-economic and political properties, including both national and international aspects. This progress towards industrial-scale fisheries led to the involvement of scientific research, first aiming to improve production efficiency, and then, to protect ecosystems as resources exploited for fisheries activity, by mitigating their adverse impacts. During this evolutionary progress, SSF was usually neglected because of their limited production ability, and thus minimal economic contribution, until the later phase when the protection of ecosystem resources gained sufficient importance. As a result of this, many countries lack data on SSF, undermining efforts for the creation of proper policies for this type of fisheries. The aim of this study was to evaluate the productivity and the effects of some demographic characteristics, boat structures, and some cost (input) items on the net profit of SSF in the Black Sea. The eligible sample for this study consisted of 5575 small-scale fishing boats in the Black Sea. The number of fishers to be surveyed was determined as 315 using the “Simple Random Sampling” method, based on operators of boats < 12 m, i.e., boats in the SSF. Questionnaires were conducted face-to-face with fishers. In this study, it was tested if six parameters were investigated to determine whether they had a significant effect on net profit in SSF. These parameters were: (1) engine power; (2) number of fishing days; (3) boat length; (4) consumption of fuel in fishing; (5) education level of fishers; and (6) overall professional experience of fishers. To do so, Simple Linear Regression Analysis was performed to determine the effect of the data considered as independent variables when the net profit was set as the dependent variable. Atlantic bonito, Sarda sarda (Bloch, 1793); whiting, Merlangius merlangus (Linnaeus, 1758); rapa whelk, Rapana venosa (Valenciennes, 1846); and turbot, Scophthalmus maximus (Linnaeus, 1758) were the most important commercial fish species for small scale fishing. When catch per boat in SSF was evaluated, Kırklareli province ranked first with 97 007 kg, with Atlantic bonito (44 778 kg) being the most common species caught. Samsun had the second-largest catch per boat with 91 761 kg. The total net profit of 303 boats was calculated as €1 794 938 and the mean net profit per boat was €5924. The highest per boat mean net profit (€25 909) was in Kırklareli. According to the results of the study, the number of days at the sea, boat length, engine power, and fuel cost had a significant effect on the net profit while education level and professional experience were not important in productivity. The economically-fragile SSF sector may need some kind of supporting subsidy. It would be beneficial to provide support to the majority of fishers active in the SSF in terms of complementary alternative employment opportunities in the regions where they are located.

Abstract The ubiquitous spread of digital networks has created techniques which can organize, store, and analyse large data volumes in an automized and self-administered manner in real time. These technologies will have profound impacts on policy, administration, economy, trade, society, and science. This article sketches how three digital data technologies, namely the blockchain, data mining, and artificial intelligence could impact commercial fisheries including producers, wholesalers, retailers, consumers, management authorities, and scientist. Each of these three technologies is currently experiencing an enormous boost in technological development and real-world implementation and is predicted to increasingly affect many aspects of fisheries and seafood trade. As any economic sector acting on global scales, fishing and seafood production are often challenged with a lack of trust along various steps of the production process and supply chain. Consumers are often not well informed on the origin and production methods of their product, management authorities can only partly control fishing and trading activities and producers can be challenged by low market prices and competition with peers. The emerging data technologies can improve the trust among agents within the fisheries sector by increasing transparency and availability of information from net to plate.

(Mollusca: Cephalopoda) in the northern Adriatic Sea in relation to the main fishing gears employed."

Full textAbstract:
The cuttlefish (Sepia officinalis Linnaeus 1758) represents one of the most important coastal fishery resources of the Mediterranean Sea. For Italy, 45% of cuttlefish landings (2,328 t) originates from coastal regions of the northern Adriatic Sea: Veneto, Marche, Emilia Romagna and Friuli Venezia Giulia. In terms of economic value this species represents about 8% (~€ 16.5 million) of the production from this basin. From May 2004 to October 2005, cuttlefish were purchased from commercial landings of the Grado fishery fleet. At least 30 specimens were randomly taken each month from each fishing method employed for this species: bottom trawl (cod end mesh size 40 mm), rapido trawl, trammel net (mesh size of inner panel 30 mm) and cuttlefish specific trap. The main biological aspects, such as size, sex ratio, reproductive stage and diet in relation to both the season and type of fishing gear were analyzed. 1,495 specimens, ranging from 3.5 to 18.0 cm mantle length, were analyzed. In relation to the observed size and reproductive stage of individuals caught, trammel nets and cuttlefish traps both appeared to target sexually mature individuals, whilst trawling gear were not selective for either recruits or spawners. In total 34 prey taxa were found in the stomachs of S. officinalis: crabs and bony fish species were the most important prey, although the latter appeared mostly in the largest specimens. Finally the fullness index revealed that cuttlefish caught by trawling were more suitable for diet analysis than those caught by static gear. In this way the contribution of the present paper was to give new insights on the biological parameters of this species in relation to the main fishing gears employed in the northern Adriatic Sea.

<p>Coastal and small islands are faced with various significant challenges. The trend shows that the region suffered largely from habitat destruction, changes on natural processes of ecosystems and<br />pollution. Coastal and small islands regions became increasingly complex as conflicts of interest occur, both within the community and at the government level. Thus, activities to be placed within this region should consider the compatibility between needs and the region’s ability in providing resources. This study aims to develop a management strategy for unpopulated islands in utilization of natural resources. The research was conducted through descriptive evaluative method, using spatial analysis to obtain suitability between the waters and the carrying capacity of the area using<br />ArcGIS 10.3. On the other hand, management strategies were formulated using Analytic Hierarchy Process (AHP) model. The ecological potentials of Nusa Manu and Nusa Leun Islands covers diving, snorkeling tours, mangrove tracking and beach tourism, grouper fish aquaculture within floating net<br />cages and fishing grounds. The potentials are suitable and can be utilized for various activities with priority on conservation-based marine ecotourism. This management strategy sides with the people, opens employment opportunities and able to encourage economic growth while maintaining the sustainability aspects of natural resources.</p>

ABSTRAKNelayan di Desa Toniku Kabupaten Halmahera Barat, awalnya menggunakan bagan perahu untuk menangkap ikan teri Stolephorus sp. sebagai umpan perikanan pole and line, akan tetapi pada saat ini banyak tertangkap selain teri yaitu juvenil dan larva ikan, ini permasalahan yang perlu dikaji komposisi tangkapan dari bagan perahu. Tujuan penelitian adalah menganalisis komposisi tangkapan, by-cacth, discard, dan aspek ekonomi. Penelitian dilaksanakan di perairan desa Toniku Kabupaten Halmahera Barat, dari tanggal 1 sampai 9 Juni 2018. Metode penelitian adalah metode survei. Obyek penelitian yaitu ikan hasil tangkapan bagan perahu. Hasil penelitian menunjukkan bahwa tangkapan bagan perahu didominasi oleh ikan target tangkap, yaitu; ikan teri (Stolephorus sp) sebesar 86,295%, tangkapan sampingan 12,335% dan tangkapan yang dibuang 1,370%. Tangkapan sampingan didominasi ikan peperek (Leiognatus sp) yaitu 5,575%. Nilai keuntungan Usaha bagan perahu sebesar Rp 93.047.200,00/tahun dengan B/C ratio 2,96. Berdasarkan perbandingan antara target tangkap dengan by-catch dan discard, bagan perahu di Desa Toniku Kabupaten Halmahera Barat dikategorikan alat tangkap ramah lingkungan dan secara finansial menguntungkan dan layak dikembangkan (berkelanjutan). Walaupun discard rate pada bagan perahu rendah namun usaha-usaha untuk meminimumkan tetap perlu dilakukan. Salah satu usaha yang bisa dilakukan adalah sortir, dan hasil tangkapan yang tidak memiliki nilai ekonomis dibuang ke laut dalam keadaan masih hidup. ABSTRACTFishermen in Toniku Village, West Halmahera Regency, initially used a boat lift net to catch anchovy Stolephorus sp. As bait for pole and line fisheries, but at this time many were caught besides anchovy, namely juvenile and fish larvae, these are problems that need to be studied from the boat lift net. The study objective was to analyze the composition of catchs, by-catch, discard, and economic aspects. The research was carried out in the waters of Toniku village, West Halmahera Regency, from June 1 to 9, 2018. The study method is the survey method. The object of the research is the fish catch by the boat lift net. The study results show the catch of the boat's lift net was dominated by main catch, namely; anchovy (Stolephorus sp) is 86.295%, by-catch 12.335% and discard 1.370%. The bay-catch is dominated by peperek (Leiognatus sp) which is 5.575%. Value of the boat lift net business profit of Rp. 93,047,200.00/year with B/C ratio 2.96. Based on the comparison between catch targets and by-catch and discard, the boat lift net in Toniku Village, West Halmahera Regency is categorized as environmentally friendly and financially profitable and feasible (sustainable) fishing gear. Although the discard rate on the boat chart is low, efforts to minimize it still need to be done. One effort that can be done is sorting, and catches that have no economic value are dumped into the sea while still alive.

Fenomena ini juga menunjukkan telah terjadi jalan pintas dan bersifat jangka pendek tanpa melihat dampak-dampak yang ditimbulkan baik dari segi sosial, ekonomi dan lingkungan. Upaya untuk mengatasi problem penggunaan jaring arad di Pantura tampaknya tidak mudah. Pemerintah telah mengeluarkan peraturan yang melarang penggunaan jaring arad. Akan tetapi tampaknya kebijakan pelarangan alat tangkap tersebut menghadapi masalah pada implementasi di lapangan. Penegakan hukum belum bisa dilakukan secara optimal. Hal ini antara lain disebabkan masih pasifnya para petugas dalam mengontrol terjadinya pelanggaran, dan keberadaan petugas tidak didukung oleh prasarana yang memadai. Jadi ada kesan bahwa pelarangan alat tangkap tersebut tidak mendapat dukungan dari aparat penegak hukum, sehingga masalah yang berkaitan dengan penggunaan alat tangkap yang sudah dilarang tersebut tidak dapat terselesaikan secara tuntas. Tittle: The Operation of Arad Net in The North Coast of Java: Problems and Their Solutions.The article of “The Operation of Arad Net in The North Coast of Java: Problems and their Solution” discusses the problem of fishers conflict especially related to the usage of arad net in North Coast of Central Java and West Java. This article was conducted in Rembang and Cirebon Regencies. Qualitative approach was used in the research. Results showed that the exploitation of shrimps using a semi-trawl called ‘jaring arad’ was considered a social phenomenon of fishing to cope daily life. This phenomenon also shows that there was a short term profit orientation without considering long-term impact on social, economic and environment aspects. The effort to reduce the used of arad in Pantura was not easy. Government has erected the regulation on banning the used of arad. However, low enforcement was quite weak. This is because the officer could not effectively control territory and was not supported by adequate infrastructure and equipments. That is why, it seemed that regulation on banning the use of arad was not supported by adequate enforcement efforts. Hence, problem related the use of Arad could not be solved effectively.

Ikan tongkol abu-abu (Thunnus tonggol) tertangkap di Laut Cina Selatan dan bernilai ekonomis penting. Trend produksi berfluktuatif, 2009-2011 meningkat, menurun pada 2013 dan 2015 meningkat kembali. Kondisi fluktuatif juga ditunjukkan dari nilai CPUE jarring insang hanyut. Seiring dengan meningkatnya permintaan, pemanfaatan tongkol abu-abu harus dikelola agar ketersediaannya tetap berkesinambungan. Tujuan penelitian adalah mengkaji biologi reproduksi ikan tongkol abu-abu sebagai bahan kebijakan pengelolaan yang lestari. Kajian yang dilakukan meliputi struktur ukuran, hubungan panjang dan berat, nisbah kelamin, tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG), rata-rata ukuran pertama kali tertangkap dan matang gonad serta kebiasaan makanan. Pengumpulan sampel dilakukan oleh enumerator di PPN Pemangkat, Kalimantan Barat pada Januari sampai November 2014. Data yang dikumpulkan meliputi panjang, berat, jenis kelamin, tingkat kematangan gonad, dan isi lambung. Hasil penelitian menunjukkan sebaran panjang ikan tongkol abu-abu pada kisaran 29-80 cm dan modus 47-49 cm, pertumbuhan bersifat isometrik, nisbah kelamin jantan dan betina menunjukkan kondisi seimbang, ukuran rata-rata pertama kali tertangkap (Lc) pada panjang 47,8 cm, ukuran pertama kali matang gonad (Lm) 41,1 cm. Dari data TKG dan IKG, prediksi musim pemijahan berlangsung pada Mei dan Agustus. Hasil pengamatan isi lambung menunjukkan bahwa ikan tongkol abu-abu tergolong ikan karnivora. Dari hasil penelitian rekomendasi untuk kebijakan pengelolaan adalah penetapan penutupan musim dan daerah penangkapan pada bulan Mei dan Agustus pada wilayah perairan yang diduga sebagai daerah pemijahan, penetapan kuota ukuran tangkapan lebih besar dari Lm 41,1 cm dan alternatif wisata pancing dengan ukuran mata pancing yang hanya menangkap ukuran yang sudah matang gonad. Longtail tuna (Thunnus tonggol) were caught in the South China Sea has important economic value. The catch trend fluctuates, increases from 2009 - 2011, decreases in 2013 and increase in 2015. Fluctuating condition is also showed from CPUE drift gill net. Along with the escalation demand, the utilization longtail tuna should be managed in order to keep it sustainable. The objective of the research was to study the reproductive biology of longtail tuna as suggestion for sustainable management. Studies performed on the size structure, the length and weight relationship, sex ratio, maturity stage, gonad somatic index (GSI), Length at first capture and Length at first maturity and food habits. Sample collection was conducted by enumerators at Pemangkat Fishing Port, West Kalimantan in January to November 2014. Data containing length, weight, sex, maturity stage, and stomach contents. The results showed that the length of longtail tuna in range of 29-80 cm and the mode of 47-49 cm, the growth is isometric, the sex ratio male and female showed a balanced condition, the average Length at first capture (Lc) at 47.8 cm, Length at first maturity (Lm) 41.1 cm. From the Maturity stage and GSI data, the predicted spawning season takes place in May and August. Observations o of the stomach contents showed longtail tuna is carnivorous fish. From results of the research recommendation for the management policy is the determination of the close seasons and close areas in May and August on the location suspected as spawning areas, determination of the legal size is bigger than 41.1 cm and encourage the recreational fishing as alternative with the size of the hook which is only catch the mature size fish.

This research undertaking was conducted in Aparri, Cagayan, particularlyat the Cagayan River Estuary. The study generally characterized the catch rates and socio–economic dynamics of the filter net fisheries of the said estuary. The study utilized of questionnaires to obtain the data. It also considered personalinterviews and observation to validate the data. Results revealed that majorityof the respondents were married, have children ranging from 1-4, aged 26-40,finished elementary level of education, with no extended family. Majority of therespondents were engaged in fishing without alternative source of income. Ongear species accounting, most of the drift filter net fishers consumed 1-2 hoursper haul with alamang catch of 11-20 cans per haul and 9-10 hours per haulwith 1-5 kilograms per haul for the stationary filter net fishers. Majority of thefishers have 3-4 hauls per day. On sales and sharing scheme of the drift filter netfishers, majority of the drift filter net fishers had sales of 10,000 and below perfishing trip, majority of the fishermen had a share of 500.00 per fishing trip. Asto the respondents’ involvement in community activities, most of them joinedcommunity activities despite the fact that they do not hold any position in thecommunity. There were 19 identified species that were caught by the drift filternet (DFN) and stationary filter net (SFN) for the months of May & June, withrespect to moon phases. Catch per unit effort of “saplar” was higher than that of“banwar”.Keywords: Aquatic Ecology, catch, effort, Filter Net Fisheries, descriptive design,Cagayan, Philippines

Full textAbstract:
Dol net is traditionally used for fishing along the north-west coast of India. In this study, the operational as well as economic aspects of dol net operation off Navabandar, Gujarat was studied. Dol nets operations from mechanised boats locally called as Van along Navabandar coast were considered for the present study. The overall length (OAL) of the mechanised vessels were in the range, 10-12.8 m with 2.4-3.6 m breadth and 1-1.8 m height. The total capacity of vessels was in the range 15-20 t and average fish holding capacity was 2.5 t. The fishing vessels had six cylinder engines of 87 to 105 hp. Fishermen themselves fabricated the nets for the dol net, which had seven different parts with various lengths. Kaba-sus system using steel pipes was the method of dol net fishing off Navabandar. They were locally known as Bochi, Patiya, Aor, Trijo, Bangu, Chothi and Jalo. The study indicated that the profit of a dolnetter at Navabandar in a year was `2,88,122.
