Abstract Citanduy river is one of the priority watersheds in West Java. Information on capture fisheries resources in Citanduy, however, river is limited. The aim of this study was to assess the information of capture fisheries resources in that river. The method used in this study was a survey method, by collecting data in the field, and then analyzed it in the laboratory. This research was conducted in 2018. Samples of fish were collected through the active participation of fishers with various types of fishing gear. The identification of fish and fishing gear used some references. Some fish caught were preserved in formalin solution and identified. The dominant catch in Citanduy River is Mystacoleucus marginatus and Cyprinus carpio. Other economic fishes catch in Citanduy river are Oreochromis niloticus, Osteochilus vittatus, O. mossambicus, Trichogaster trichopterus, Hemibragus nemurus, Hampala macrolepidota, Channa striata, Moolgarda seheli, and Glossogobius giurus. The fishing gears used by fishers are hooks and lines, cast nets, scope nets, traps, and gill nets. The inland capture fishery in Citanduy river is still a secondary sector for the interests of local government.The current condition of capture fisheries in Citanduy is not the main livelihood for fishers. The inland capture fisheries in Citanduy is still using a simple fishing gear and do not have more complex tools. Citanduy river has potential source of economic and protein food, particularly for local community. Regarding in these potential, management of environment could be the major domains in fisheries management. The policy of local government in handling non-selective fishing gear and restocking activity could be maintain the sustainable fish resources in Citanduy river.

The sustainability of capture fisheries development in Indonesia faces various challenges, such as climate change, pollution, resource degradation, and pressure from fluctuating commodity prices. Furthermore, a policy breakthrough with proper strategy is needed in realizing sustainable capture fisheries development. This study aims to formulate the most appropriate policy from several existed alternative policies to achieve sustainable capture fisheries development. Primary and secondary data are used in this study. A prospective analysis (SMIC-Prob-Expert) approach is used to formulate priority policy scenarios for capture fisheries development in Indonesia. As results, the analysis brings about six main priority alternative policies, namely: (1) increasing utilization of fisheries resources (SDI), (2) increasing capture fisheries productivity, (3) increasing fishermen household income, (4) providing fisheries insurance/social security, (5) improving status utilization of SDI, and (6) increase in the value of capture fisheries non-tax state revenue (PNBP). The analysis shows that policy scenario 01 (111111) or by implementing all alternatives policy simultaneously is the best choice. If the policymakers are faced with options, then the policy scenario becomes the last option to be taken simultaneously is not to choose a policy of providing insurance/social security to fishermen; or in the in this case policy scenario 05 (111011).

The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community with diversified livelihood strategies for whom inland fisheries are extremely important. Many drivers affect the fisheries, including internal fisheries management practices. There are also many drivers from outside the fishery that influence the state and functioning of the environment as well as the social and economic framework within which the fishery is pursued. The drivers affecting the various types of inland water, rivers, lakes, reservoirs and wetlands may differ, particularly with regard to ecosystem function. Many of these depend on land-use practices and demand for water which conflict with the sustainability of the fishery. Climate change is also exacerbating many of these factors. The future of inland fisheries varies between continents. In Asia and Africa the resources are very intensely exploited and there is probably little room for expansion; it is here that resources are most at risk. Inland fisheries are less heavily exploited in South and Central America, and in the North and South temperate zones inland fisheries are mostly oriented to recreation rather than food production.

Perikanan tangkap di Indonesia memiliki peran strategis, namun dalam pelaksanaannya tidak terlepas dari kompleksitasnya pemasalahan yang dihadapi. Ancaman terhadap keberlanjutan sumber daya ikan dan kapasitas pelaku usaha menjadi perhatian utama dalam mewujudkan perikanan tangkap berkelanjutan. Penelitian ini bertujuan unutk mengkaji kondisi pembangunan perikanan tangkap yang telah dilaksanakan di Indonesia, yang difokuskan pada pada dua aspek utama, yaitu komoditas utama perikanan tangkap tuna, tongkol dan cakalang (TTC) dan pelakunya serta bagaimana strategi keberlanjutannya. Selain itu, penelitian ini juga mencoba merumuskan indikator prioritas yang dapat digunakan untuk mengukur keberlanjutan pembangunan perikanan tangkap. Penelitian ini menggunakan metode analisis isi dan untuk mengetahui prioritas indikator digunakan pendekatan metode urgency, seriousness and growth (USG). Hasil kajian memberikan gambaran bahwa manfaat dari perikanan tangkap di Indonesia belum merata dirasakan. Struktur perikanan tangkap di Indonesia masih didominasi nelayan skala kecil dan berpengaruh terhadap produksi komoditas utama (TTC), Illegal, Unreported and Unregulated Fishing (IUUF) menjadi ancaman terbesar bagi keberlanjutan perikanan tangkap. Kondisi sumber daya ikan dan perikanan skala kecil menjadi indikator prioritas utama untuk mengukur keberhasilan perikanan tangkap yang berkelanjutan, sehingga kedepannya diperlukan perbaikan terhadap pengelolaan perikanan yang dapat ditempuh melalui pengelolaan sumberdaya ikan berbasis WPP melalui penguatan kelembagaan dan dukungan sarana prasarana. Title: Capture Fisheries in Indonesia: Portraits and Challenges of SustainabilityCapture fisheriy in Indonesia has a strategic role, though its implementation encounter such a complex problem. The threat on the sustainability of fish resources and fisher capacity are the major concern in creating sustainable capture fisheries. This study aims to examine the condition of capture fisheries development in Indonesia that focused on two main aspects: (1) the main commodities of tuna, little tuna and skipjack (TTC) and its fishers, and (2) the strategy for its sustainability. In addition, this study tries to formulate priority indicators to measure the sustainability of capture fisheries development. The research used content analysis method as well as Urgency, Seriousness and Growth (USG) method to determine priority indicators. Results of the study showed that the benefits of capture fisheries in Indonesia are not evenly distributed. Small-scale fishers dominate the structure of capture fisheries in Indonesia and affect the production of major commodities (TTC). In addition, Illegal, Unreported and Unregulated Fishing (IUUF) is the biggest threat to the sustainability of capture fisheries. The condition of fish resources and small-scale fishers is a top priority indicator to measure the success of sustainable capture fisheries, so it is necessary to improve future fisheries management based on WPP through institutional strengthening and infrastructure support.

The level of purse seine business income is determined by the efficient allocation of resources for alternative capture fisheries activities. If resources are not used efficiently, there will be unexploited potential to increase income and create surpluses. Conversely, if resources are allocated efficiently, additional capture fisheries can be obtained through growth-oriented development efforts. Therefore, it is important to identify the efficient use of resources to determine the existence of purse seine fisheries. The results show that the estimated technical efficiency of the catch with SPF (Stochastic Production Frontier) analysis for purse seine fisheries in Central Maluku Regency and Ambon was influenced by the length and width of fishing gear, number of fishermen, amount of investment value and time of capture operations. The minimum value of catch technical efficiency is 0.10 and the maximum is 0.99 with an average 0.48. Factors influencing the technical inefficiency of fishing are the experience of captain and the education level of fishermen. Purse seine fishery business in Central Maluku Regency and Ambon City is feasible to be developed, showing by NPV value Rp. 30,514,684 / year, IRR 23.97% and B / C ratio 5.85. The average return on investment (PP) based on the analysis is 2.16 years, with BEP price Rp. 6,606 and BEP production 3,765 kgs. The main priorities of purse seine fisheries development policy strategy in Central Maluku Regency and Ambon are the development of assistance to fishing groups, the development of appropriate technology to handle catches, increase fisheries production, and infrastructures development.

Community-based approaches have gained significant attention in inland open water fisheries management in Bangladesh. This article focuses on the challenges and opportunities of the inland open water fishery resources under community-based management approaches. The present study employed management information of waterbodies between 1991 and 2014 across a range of geographical locations and habitats. The study reveals that coordinated management of water bodies is essential given common management issues of waterbodies. Present study also reveals that complexity of different property rights and the diversity of users within individual clusters have had cumulatively adverse effects on fisheries. The study shows that different fisheries management policies promoted by the government of Bangladesh over time to have varied in strength and appropriateness. This study concludes that open water fisheries management through fishers’ community involvement is promising approach in Bangladesh but a variety of socio-economic factors that affect the governance in its implementation.

Increasing the amount of demand for natural resource needs is increasing. One of them is natural resources in the sea and coast. The current condition of capture fisheries in Indonesia is not yet optimal. This is indicated by the increase in the volume of capture fisheries production which is very slow. The purpose of this study is to make data classification for the prediction of the average volume increase in capture fisheries with data mining techniques. Data mining techniques are applied to determine the data patterns of the capture fisheries dataset, so the results of the classification can be applied to evaluate the factors that affect the volume of capture fisheries. The classification algorithm used is C45. The results of the classification were tested with rapidminer in classifying data. The level of performance is indicated by the accuracy value. The accuracy value is obtained by testing the results of the classification of training data and testing data. Comparison of accuracy values between the algorithms used can be seen the best algorithm in making the classification of capture fisheries data.

To manage with the Indonesian vision as the biggest producer of fisheries in 2015, capture,aquaculture, and post-harvest fisheries should be ready to operate at large or business scale.Consequently, industrialization should be promoted since this is the most appropriate way tomanage fisheries in business manner. Though it has a positive goal to maximize the utilization offisheries resource for the improvement of economic and prosperity of Indonesian people, however,industrialization undoubtedly retains a negative impact in terms of threats on the sustainability offishery and other natural resources. This article summarises review and analysis aiming to developan ideal model in order to strengthen the fisheries industrialization in Indonesia. Based on previousweaknesses, the ideal model is the one that reflects an inclusive and holistic manner, suitable forvarious characteristics of industries in each typical areas and people of Indonesia, with the emphasison competitive advantage, untraditional, and commercial basis, especially in respect to thedevelopment of a strong fisheries business. This kind of model should also maintain harmonizedand coordinated programs and actions between involved related institutions. Research supportsare needed to develop and test the most appropriate model. Also, in technical basis, innovationson fish capture, aquaculture, as well as processing technologies are urgently needed as acomplement to the developed model of fisheries industries. One thing that should be kept in mindis the importance of management and conservation of natural resources, including resource forfisheries capture and aquaculture, germ plasms and genetic fish resources, as well as marinemicroorganisms, as these all are the main assets for the development of marine and fisheries inIndonesia.

La sécurité alimentaire, qui est la garantie de l’approvisionnement et de la qualité des aliments tout en gérant les ressources de manière durable, est intrinsèquement liée à la connaissance de la biologie et l’écologie des espèces consommées. Dans un contexte de dérèglement climatique menaçant la salubrité des produits de la mer, il est donc nécessaire d’établir un référentiel sur le fonctionnement des systèmes marins, ainsi que sur l’occurrence des nutriments et des contaminants dans les produits de la mer. C’est d’autant plus important pour les Petits Etats Insulaires en Développement (PEID), qui dépendent des ressources marines pour leur subsistance, et où les produits de la pêche sont la première source de protéines et micronutriments (éléments traces essentiels) pour les populations locales. Malgré l’importance des systèmes tropicaux pour la sécurité alimentaire, ces systèmes sont peu étudiés comparés aux systèmes polaires et tempérés. Cette thèse vise à mieux comprendre le fonctionnement des systèmes marins tropicaux, et à établir un référentiel sur l’occurrence des micronutriments et des contaminants métalliques dans les produits de la pêche aux Seychelles (Océan Indien), un PEID tropical. En étudiant les concentrations en éléments traces aux niveaux inter- et intraspécifique, nous avons identifié différents facteurs intrinsèques et extrinsèques influençant la bioaccumulation de ces éléments dans les ressources marines tropicales. Nous avons aussi montré l’importance de considérer différentes échelles (individu, espèce et écosystème) pour mieux comprendre l’occurrence des éléments traces essentiels et non-essentiels dans les produits de la merFood security, that is guarantying food supply and quality while sustainably managing resources, is closely linked to knowing the biology and ecology of consumed species. In a context of global changes that are threatening seafood safety, it is thus necessary to establish baselines on marine ecosystem functioning, as well as nutrient availability and contamination occurrence in seafood. This is all the more important in Small Island Developing States (SIDS), where populations rely on marine resources for their subsistence, and where capture fisheries resources are the main sources of proteins and micronutrients (i.e. essential trace elements) in local populations’ diet. In spite of the importance of tropical systems in ensuring food security, they remain largely understudied compared to polar and temperate systems. This thesis thus aims to better understand the functioning of tropical marine systems, and to establish a baseline on micronutrient availability and metal(loid) contamination in a wide diversity of capture fisheries resources from the Seychelles (Western Indian Ocean), a tropical SIDS. By investigating trace element concentration patterns at the inter- and intraspecific levels, it was possible to identify intrinsic and extrinsic factors influencing trace element bioaccumulation in tropical capture fisheries resources. We thus highlighted the importance of considering different scales (individual, species, and ecosystem) to better understand essential trace element availability and non-essential trace element occurrence in seafood

The Peruvian anchoveta fishery was for nearly 60 years characterized by the unsustainable dynamics of open access resource pools. This thesis investigates whether the 2009 Peruvian Legislative Decree 1084 on Individual Vessel Quotas (IVQ's) is an effective response to the industrial overcapacity and race-to-fish problems that threatened the environment before its implementation. It employs Common-Pool Resource theory to assess the impact of the new IVQ scheme on collective dynamics, and Ribot and Peluso's access theory (2009) to elucidate evolving power relations in the fishery. In this framework, DL1084 is evaluated as a regulatory instrument, as a lens on fisheries governance in Peru, and as a source of insight into how environmental impact serves in developing regulations of natural resource exploitation. A triangulated mixed-method design is employed: (1) a two-stream literature review of fisheries management and of the fishery's political ecology; (2) a quantitative analysis of daily state-published landings reports; and (3) seven in-depth intensive interviews with key actors in the fishery, conducted in Peru over two field-trips of approximately 2 months in total. Results indicate that although IVQ's supported existing trends towards large-scale economic efficiency and altered extreme competitive strategies previously associated with open access, fishing companies have built larger ships, favour bigger catches and still concentrate fishing effort around a given annual peak. Meanwhile, capacity has again increased in the unregulated artisanal fishery sector. DL1084 appears to reflect a broader process of growing private sector involvement in managing the fishery, made official by its institutionalization of market self-regulation. Ultimately, it evidences deep structure and capacity limitations in the state's ability to govern marine resources. The law was nevertheless seen as a landmark for the environmental legal process in Peru and an opportunity for reform. This thesis suggests that studying such legislations can provide insight into state identity and the evolving relationship between a nation and its geography.Durante casi 60 años, la pesquería peruana de anchoveta estaba caracterizada por las dinámicas insostenibles de la explotación de recursos de propiedad común en situación de acceso abierto. Esta tesis investiga si el Decreto Legislativo Peruano 1084 (DL1084) sobre Límites Máximos de Captura por Embarcación (LMCE) es una respuesta efectiva a los problemas de sobrecapacidad industrial y de carrera por el recurso que amenazaban el ambiente antes de su aplicación en 2009. Se basa en la teoría de los Recursos de Propiedad Común (Common-Pool Resource theory) para evaluar el impacto del nuevo modelo de gestión por LMCE sobre las dinámicas colectivas, y en la teoría del Acceso de Ribot y Peluso (2009) para trazar la evolución de las relaciones de poder en la pesquería. En este marco, el DL1084 es evaluado como herramienta regulatoria, como lente sobre la gobernanza pesquera en el Perú y como reflejo del proceso por el cual el impacto ambiental sirve como base para el desarrollo de regulaciones sobre el acceso a recursos naturales. Sigue un diseño triangulado de métodos combinados: (1) una revisión de literatura en dos ramas de la gestión de pesquería como campo general y de la ecología política de la pesquería de anchoveta; (2) un análisis cuantitativo de los informes diarios de desembarques publicados por el estado (IMARPE); y (3) siete entrevistas intensivas de fondo con actores claves en la pesquería, realizadas en Perú durante dos visitas de aproximadamente dos meses en total. Los resultados indican que a pesar de que los LMCE soportaron una tendencia existente hacia una eficiencia económica de mayor escala y alteraron las estrategias competitivas extremas asociadas con el acceso abierto, las empresas pesqueras han construido embarcaciones más grandes, favorecen capturas de mayor tamaño y todavía concentran su esfuerzo pesquero alrededor de un pico anual de abundancia. En paralelo, ha aumentado la capacidad de captura en el sector artesanal, el cual no cuenta con límites de captura. El DL1084 aparece como parte de un proceso más general de creciente involucramiento del sector privado en el manejo de la pesquería, haciéndolo oficial por su misma institucionalización de la autorregulación del mercado. Por último, pone en evidencia profundas limitaciones de estructura y de capacidad en el estado en cuanto a cómo gobierna los recursos marinos. La ley ha sin embargo sido vista como un precedente importante para el proceso legislativo ambiental en el Perú así como una oportunidad para impulsar otras reformas. Esta tesis sugiere que el estudio de tales legislaciones puede ofrecer una mirada sobre los procesos de formación de la identidad de un estado y sobre la evolución de la relación entre una nación y su geografía.

<em>Abstract</em>.—Lakes are very important resources for fisheries production in China. The total area of lakes for commercial fisheries in China reaches 1.02 million ha, which accounts for 18% of the total freshwater aquaculture area. China has gained rich experience developing lake commercial fisheries over the past 60 years. In the 1950s, lake fisheries were primarily focused on the capture of natural aquatic animal species. With the success of the artificial reproduction of the four domestic carps (Silver Carp <em>Hypophthalmichthys molitrix</em>, Bighead Carp <em>H. nobilis </em>(also known as <em>Aristichthys nobilis</em>), Grass Carp <em>Ctenopharyngodon idella</em>, and Black Carp <em>Mylopharyngodon piceus</em>), stock-enhanced fisheries became the main production method in the 1960s and 1970s. During this period, large-scale resources investigations all over China were conducted, some stocking and management theories that were based on primary production developed, and fish production potentials for lakes were determined. The united fishing method was created during this period, which significantly increased the capture efficiency in large lakes. In the 1980s, semi-intensive and intensive aquaculture methods, including application of fertilizers and artificial feeds, cage culture, and pen culture, were applied to lake and reservoir fisheries, which substantially increased fishery production and also the income of fishermen. However, intensive aquaculture in lakes has caused serious environmental problems, such as ecosystem degradation, exhaustion of natural fisheries resources, decreased biodiversity, and increased eutrophication. Sustainable development of fisheries in lakes of the Yangtze River basin has been facing unprecedented challenges, both to the environment and to human society. More and more attention has focused on the balance between fisheries development and environmental protection in the past two decades. Ecofishery is a possible solution to this potential conflict. As a strategy for lake fisheries reform, it is suggested that use of natural food resources in lakes should be more efficient than present, and lake fisheries should be developed based on ecosystem restorations.

Aquaculture is instrumental for increasing global fish production, but its ecological effects can create new pressures on the fishing grounds that small-scale fisheries (SSFs) depend on. As a result, achievement of SDGs 1 (end poverty) and 2 (end hunger) in societies of the Global South is compromised, and that of SDG14 (sustainable marine resources) is complicated. Using new evidence from Lake Victoria, which harbors Africa’s largest inland SSFs and a fast-growing aquaculture industry, this chapter examines how science, technology, and innovation (STI) can support ecologically and socially sustainable governance of fisheries resources. The author argues that a sustainable expansion of aquaculture needs to protect the natural resources that small fishers depend on while maximizing their ability to benefit from fish-farming. STI-based solutions, if integrated in a transformation governance approach, can secure and expand contributions from capture fisheries and aquaculture to help achieve SDGs 1, 2, and 14. The concept of transformation governance is based on a threefold structure: to increase eco-efficiency, redistribute access to natural resources, and recognize eco-sufficiency as a guiding principle. By applying this threefold resource-governance approach, the potential for STI-based solutions to provide greater overall eco-efficiency is utilized, restrictions on total resource use prevent rebound effects, and the principle of redistribution promotes a focus on appropriate technologies for small-scale resource users.

<em>Abstract</em> .—Understanding the role and value of small-scale fisheries to livelihoods and food security is a key challenge in conserving fishery resources. This is particularly true for small-scale inland fisheries, one of the most underreported and undervalued fisheries sectors that also increasingly faces environmental and societal change. Gender plays a central role in the different ways in which inland fisheries contribute to food and nutritional security in developing countries. The role of women in inland fisheries is significant, with millions of women contributing to dynamic capture fisheries and aquaculture supply chains. The role of women in inland fisheries, however, is less visible than the role of men and is often overlooked in policymaking processes. The need for participatory community-based approaches has been widely recognized in natural resource management literature as a means to capture people’s perspectives and empower marginalized groups. The Photovoice method is increasingly used as a participatory tool in health, social, and environmental research, but has had little adoption in inland fisheries research to date. The aims of this paper are (1) to review and evaluate the effectiveness of an emerging participatory method, Photovoice; and (2) to present a modified Photovoice method, applicable to the context of small-scale fisheries, to advance understanding of gender and socioecological dimensions. We outline the strengths and limitations of the method and highlight that it can be used as a tool for triangulation of mixed research methods or independently. We argue that Photovoice, as a participatory tool in fisheries research, has the potential to provide rich, qualitative, context-specific, untapped sources of knowledge to advance fisheries research and management. The use of Photovoice in the context of small-scale inland fisheries and aquaculture research is a timely endeavor given heightened interest to obtain insights into the previously overlooked aspects of gender and the need for more policy relevant information.

<em>Abstract</em>.—At the extreme southern boundary of its range, the lake sturgeon <em>Acipenser fulvescens </em>was once an important biological component of the Coosa River system of Georgia–Alabama. During the 1970s, the population was extirpated by the combined effects of overfishing and degraded water quality. Over the past 20 years, water quality has improved, and in 2002, the Georgia Department of Natural Resources initiated a lake sturgeon reintroduction program with the goal of establishing a self-sustaining population within 20 years. From 2004 to 2007, we evaluated the initial phase of this reintroduction program by quantifying poststocking survival and seasonal habitat use of juvenile lake sturgeon in the Coosa River. We used gill nets and trammel nets to capture juveniles at several locations in both riverine and reservoir habitats. Fourteen individual juveniles were randomly selected for surgical implantation of radio tags to monitor their seasonal movements and habitat use. Over the 3 years of the study, we captured a total of 597 juvenile lake sturgeon measuring 231–790 mm total length. Using capture probabilities calculated from Program MARK (White and Burnham 1999), we estimated a total abundance of 789 (690–889, 95% confidence interval) juvenile lake sturgeon in 2006. Survival of each cohort from date stocked to summer 2006 varied from 1% to 14%, depending on year and size of fish stocked. Seasonal movements of juveniles varied; however, most fish occupied a relatively short reach in the lower river during summer months when water temperatures were more than 258C. At least 1% of fish stocked in each cohort have survived, and the population appears to be gradually increasing with each additional year of stocking. Further studies are needed to monitor annual recruitment and to evaluate reproductive success as first cohorts reach maturity.

<em>Abstract.</em> —Nepal is rich in water resources and fishing is a longstanding tradition. Capture fisheries are an important sector in Nepal and contribute approximately 0.5% to the national gross domestic product. The fish catch data of the Phewa, Begnas, and Rupa lakes of the Pokhara Valley from 2006 and 2011 were analyzed to determine the harvest trends of the exotic Nile Tilapia <em>Oreochromis niloticus </em> and native fish. The harvest of Nile Tilapia increased and the harvest of native fish species decreased in the lakes of Pokhara Valley. Harvest from the capture fisheries has increased in these lakes since Nile Tilapia became established. The introduction of Nile Tilapia in these lakes was accidental. Due to an increase in Nile Tilapia catches, the income of the Jalari community has increased, enhancing its livelihood. The native fishes of the Pokhara Valley lakes, however, are highly valued and provide a direct livelihood for the Jalari community living around the lakes. Population growth, urbanization, tourism, agricultural intensification, illegal fishing, and the introduction of exotic fish species are the drivers that affect the capture fisheries in Phewa, Begnas, and Rupa lakes. Regular monitoring and stock enhancement programs for native fish species and selective harvesting of Nile Tilapia will mitigate the problem of overpopulation of Nile Tilapia. To control further expansion of Nile Tilapia into other natural lakes, reservoirs, and rivers of Nepal, native fish conservation policy, laws, and protocols should be rigorously enforced. This paper discusses the drivers of fisheries, the increasing trend of Nile Tilapia in total fish catch, and its possible effect on native fish species and the livelihood of dependent communities of the lakes of the Pokhara Valley.

<em>Abstract</em>.—A population assessment of Muskellunge <em>Esox masquinongy </em>in two connected north-central Minnesota lakes allowed evaluation of angler data when assessing various population metrics, including the residual effects of historical stocking efforts, as a nonlocal strain had been introduced into the native population during the 1970s. In 2012, the Minnesota Department of Natural Resources sampled and marked Muskellunge using trap nets during the prespawn and spawning periods and electrofishing during the postspawn period, while anglers collected data from fish caught during the 2012 open-water season. Anglers released all fish after collecting a scale for genetic analysis. Microsatellite DNA genotypes were used to differentiate individuals, thus identifying recaptures, and to estimate ancestry derived from the stocked strain. Anglers reported catching 16% of individuals marked by biologists. Of Muskellunge reported by anglers, 78% were from the lake where they were initially captured while 22% were reported in the lake opposite their initial capture. Postspawn movements suggested that more individuals migrated from the lake characterized as having preferred spawning and nursery habitat to the lake characterized as having preferred summer habitat and prey. The age- and length-frequency distributions of fish captured by anglers and trap nets were similar, while electrofishing sampled younger and smaller fish, likely because it occurred postspawn when many adults had moved off shore. The best estimate of adult population size was produced by a model incorporating fish length as a covariate. Density was estimated at 0.70 adults per ha or 1.92 adults per littoral ha. Higher percentages of nonlocal ancestry were associated with smaller maximum size potential (<em>L<sub></em>∞</sub> ) in von Bertalanffy growth models. Our study described key population characteristics for a Muskellunge population while demonstrating that anglers could reliably collect several specific types of data that supplement data collected by management agencies.

<i>Abstract</i>.—Cryptic or unobserved fishing mortality in marine and freshwater fisheries has received much attention in recent decades and in this chapter we discuss various forms of cryptic mortality in Paddlefish <i>Polyodon spathula</i>. Specifically, we review the literature on catch-and-release (CAR) mortality in recreational sport fisheries, bycatch mortality in commercial fisheries, and wounding of Paddlefish entrained through dams or struck by recreational or commercial vessels. We also discuss opportunities to mitigate some forms of cryptic mortality. Indirect evidence suggests that CAR mortality of Paddlefish snagged in sport fisheries is minimal, probably because many of those fisheries occur when water temperatures are cool. Similarly, ample evidence points to minimal postrelease mortality of Paddlefish captured in commercial or research gill nets fished for short periods of time or overnight at cool (<11°C) water temperatures. Conversely, Paddlefish netted in warm (>16°C) waters experience high (35–71%) mortality rates. Chondrosteans exhibit depressed stress responses and faster recovery than teleosts and that trait may explain why Paddlefish often exhibit high postrelease survival after encountering fishing gear. Cryptic fishing mortality of Paddlefish arising from fishers targeting other commercial species has received scant attention. The spread of Asian carp <i>Hypophthalmichthys</i> spp. in the Mississippi River basin has prompted aggressive harvest strategies during which Paddlefish are often captured, which argues for increased scrutiny of Paddlefish bycatch in those fisheries. A final source of cryptic mortality of Paddlefish are mortal wounds resulting from boat and propeller strikes, and dam passage. Propeller strikes are a high-profile concern for endangered marine fish and sea mammals, but it is not clear whether this line of inquiry for Paddlefish warrants further study. Paddlefish in some locales experience high rates of amputated or damaged rostrums resulting from impacts with boats, or entrainment through turbines or passage through flood gates, and body condition is usually poorer in injured fish.

Abstract Aquaculture is currently the fastest growing food sector in the world and the open oceans are seen as one of the most likely areas for large-scale expansion [1], [2], [3]. The global demand for seafood is continuing to rise sharply, driven by both population growth and increased per capita consumption, whilst wild-capture fisheries are constrained in their potential to produce more seafood. A recently funded EC project, the Blue Growth Farm – BGF (GA n. 774426, 1st June 2018 – 30th September 2021) aims at contributing to this world need with an original solution. The Blue Growth Farm proposes an efficient, cost-competitive and environmentally friendly multi-purpose offshore farm concept. It is based on a modular floating structure, moored to the seabed, meeting requirements of efficiency, cost-competitiveness and environmental friendless, where automated aquaculture and renewable energy production systems are integrated and engineered for profitable applications in the open sea. In the present paper, the overall engineering approach developed to carry out the research work is presented, described and justified. Different technical and scientific challenges are addressed through an integrated industrial engineering design approach, where all disciplines are tuned to achieve the Blue Growth Farm main targets. These are represented by: i) guaranteeing expected nominal fish production thanks to advanced automation and remote control capabilities; ii) minimizing the pollution introduced at marine ecosystem level when exploiting the marine natural resources, whilst increasing the social acceptance and users community agreement; iii) maximizing the electricity production in the Blue Growth Farm potential installation area ecosystem to provide energy supply to the on-board electrical equipment and to dispatch the extra produced electric energy to the land network. Preliminary engineering design results are promising to demonstrate effective increase of safety and efficiency by reducing on-board human effort and consequently risks at offshore, thus to make commercial-scale open ocean farming a reality. The present paper introduces overall concepts and design methodology whilst other companion works submitted at OMAE2019 [4], [5], [6] provide insight of specific aspects of the Blue Growth Farm project elaborated during the first six months activity.

The Tripletail, Lobotes surinamensis, is a pelagic fish found in tropical and sub-tropical waters of all oceans. Tripletails are often associated with floating debris and make frequent incursions in bays and estuaries where they are targeted by recreational fishermen. In Mississippi waters the species is typically present during the late spring and summer season that also correspond to the period of sexual maturation and spawning (Brown-Peterson and Franks 2001). Tripletail is appreciated as a gamefish but is also prized for its flesh of superior quality. The fast growth rate of juveniles in captivity documented by Franks et al. (2001) and the excellent quality of Tripletail flesh both contribute to the potential of this species for marine aquaculture. In addition, the production of cultured juveniles would be precious to develop a better understanding of the biology, early life history and habitat use of Tripletail larvae and juveniles, a topic largely undocumented to date, through experimental releases and controlled studies. The culture of tripletail thus supports the Tidelands Trust Fund Program through improved conservation of natural resources, potential enhancement of fisheries productivity and potential development of a new economic activity on the Gulf coast producing tripletail via aquaculture. The Objective of this project was to initiate development of methods and techniques needed to spawn captive held tripletail broodfish and raise their offspring to evaluate their growth and development in captivity. In this report we will present the results of studies aiming to develop methods and protocols for captive spawning of tripletail and the first data obtained on the early development of tripletail larvae. A major issue that was encountered with tripletail broodstock development during the project lied in the difficulties associated with identifying the sex of adults caught in the wild and candidates for being incorporated in mating sets for spawning. This issue was addressed during the course of the project by examining the potential of a non-lethal method of hormonal sexing. The results of these preliminary investigations are presented in the third part of this report. All protocols used in the project were determined with the guidance of the Institutional Animal Care and Use Committee (IACUC) of the University of Southern Mississippi (USM IACUC protocol number 10100108).
