Crustacean Fisheries

Much of the biological and other research efforts on crustaceans have been driven by their importance to humans as a food source. Production comes from a diverse array of methods and scales of extraction, from small recreational or subsistence fisheries to industrial-scale operations. Most crustacean catch comes from shrimp fisheries, with over two million tons taken in 2014, mainly by trawl. The genera Acetes, Fenneropenaeus, and Pandalus account for around three quarters of this catch. Crab, krill, and lobster are the other main crustacean products (around 600,000 t crab, 380,000 t krill, and 300,000 t lobster in 2014). Trends in crustacean fisheries are broadly similar to those of other seafood, although crustaceans often target different market segments and receive higher prices than fish. Crustacean fisheries management faces many challenges with management of bycatch from trawl gears especially significant. Fortunately, crustaceans tend to be easily handled with low discard mortality, and this has enabled widespread use of regulations based on size, maturity, or sex (e.g., male-only fisheries). Total allowable catch (TAC) limits are widely used and highly effective for ensuring sustainable harvests when set responsibly using good information. TAC systems are often combined with catch share or individual transferable quota systems, which had a mixed history in crustaceans, sometimes reducing overall community benefit. This parallels the challenge facing fisheries globally of ensuring that harvests are not only sustainable but also deliver benefits to the wider community beyond the commercial fishers; management of some crustacean fisheries is at the forefront of these developments.

<em>Abstract.—</em>Urban and community fishing (UCF) projects are viewed as a way to provide easily accessible fishing opportunities to an increasingly urbanized society, thereby retaining and recruiting anglers and maintaining support for conservation of fisheries resources. Nearby, out-of-city fishery resources provide an option for development of UCF opportunities by municipalities lacking aquatic resources that can support recreational fishing. Examples of out-of-city fishing sites used as part of UCF projects in eight states are summarized. These out-of-city fishery resources not only provide relatively accessible fishing opportunities, but they also provide more diverse and often more natural fishing experiences. This diversity of fishing experiences may be useful for satisfying a broader angler constituency and aiding the transition of anglers from urban to more traditional, rural fisheries. Inclusion of out-of-city fishery resources in UCF programs can benefit from partnerships between state fisheries management agencies and municipal agencies and organizations.

Limited Success

For many years, fisheries management was based on optimizing yield and maintaining a target biomass, with little regard given to low-frequency environmental forcing. However, this policy was often unsuccessful. In the last two to three decades, fisheries science and management have undergone a shift towards balancing sustainable yield with conservation, with the goal of including ecosystem considerations in decision-making frameworks. Scientific understanding of low-frequency climate–ocean variability, which is manifested as ecosystem regime shifts and states, has led to attempts to incorporate these shifts and states into fisheries assessment and management. To date, operationalizing these attempts to provide tactical advice has met with limited success. We review efforts to incorporate regime shifts and states into the assessment and management of fisheries resources, propose directions for future investigation and outline a potential framework to include regime shifts and changes in ecosystem states into fisheries management.

The 1960S

Despite the increasing importance of marine recreational fishing, recreational fisheries management is often hampered by lack of adequate data and limited effectiveness of conventional regulations. In Shark Bay, Western Australia, snapper (Pagrus auratus) in the Eastern Gulf, Denham Sound and Freycinet Estuary have been a major attraction for recreational fishers since the 1960s. Various management measures were progressively introduced from 1998 onwards to limit snapper catches, including increases in minimum length, introduction of a maximum length, reductions in daily bag limit, a moratorium in the Eastern Gulf (June 1998–March 2003), a 6-week spawning closure in the Freycinet Estuary and, finally, the introduction of a Total-Allowable-Catch-based system in 2003. Stock assessments in 2011 indicated that spawning biomass in the Eastern Gulf and Denham Sound had rebuilt to the management target level while biomass in the Freycinet Estuary remained below the threshold level but was continuing to slowly rebuild. This paper summarising the research and adaptive management of the snapper fishery over the last 15+ years represents an important case study that addresses a range of issues typically associated with marine recreational fisheries, including assessment of stock size and recreational catch, evaluation of management regulations and active engagement with the recreational fishing community.

Abstract. Asrial E, Marzuki M, Hamid, Khasanah RI. 2021. Sustainability analysis of tomato jellyfish (Crambione mastigophora) fisheries resources management in Saleh Bay Waters, Sumbawa Island, Indonesia. Biodiversitas 22: 512-520. The tomato jellyfish (Crambione mastigophora) or gullung (local term), is endemic in Saleh Bay, Sumbawa Island, Indonesia and has been utilized as an additional livelihood by fishermen for last two decades. Its commonly caught by 2-4 fishermen/boat using scoop net, wooden fishing vessels, and lamps as attractors and collectors of jellyfish. This study aims to determine the sustainability of jellyfish fisheries management. A survey-dependent method with sampling, observation, dialogue, and documentation techniques was applied for data compilation. The rapid appraisal for jellyfish fisheries - six dimensions (Rapjellyfish-6D), based on Rapfish technique, is utilized for analysis of the sustainability status of jellyfish fisheries management. This paper describes the sustainability analysis results for two of the six dimensions of jellyfish fisheries management, namely the technological dimension (13 attributes) as an input factor and the economic dimension as an output factor (14 attributes). At present, around 8-30 baskets/boat/day of jellyfish mouth-arms are being sold to the buyers in Saleh Bay. This catch's profit is divided between the fishermen (3 parts) and the boat owner (2 parts). The analytical results show the revenue per cost ratio (R/C Ratio) as 4.75 which means that every 1.00 Indonesian Rupiah (IDR) the cost of catching jellyfish will generate IDR 4.75. The breakeven point (BEP)Price is IDR 13,158 and BEPProduction is 3.13 and 8.33 baskets/trip for the assumed price of IDR 80,000 and IDR 30,000. The technological (36.13%) sustainability status and economic (49.64%) dimension is Less Sustainable. The leverage analysis results indicate that the group of sensitive attributes in the technological and economic dimensions, respectively, consists of 5 attributes and 3 attributes. All sensitive attributes have an impact on the low value of management sustainability. The sustainability of jellyfish fisheries management in Saleh Bay has been supported by a choice of environmentally friendly fishing methods. Besides, the mouth-arm price is formed from an oligopsony market system that is not profitable for fishermen. It is suggested to the village government to build an integrated and environmentally friendly scyphozoan facility to neutralize the liquid waste generated from scyphozoan processing.

<p>The World's fisheries are in a desperate state, they have been utilised to a point where a majority of the fisheries resources are fully exploited. In addition to overfishing, the responsibility of the sad state of affairs of the world's High Seas' fish stocks can be put down to inefficient management. The high seas fisheries regime is dominated by two powerful, tried, tested and consented to norms: the principle of freedom of fishing on the high seas and the principle of exclusive flag state jurisdiction over flagged vessels on the high seas. These Grotius norms (unintentionally) obstruct effective and meaningful high seas fisheries management, and have enabled unscrupulous states and actors to take advantage of the lacunae created by the UNCLOS High Seas fisheries framework and engage in IUU fishing which has resulted in a tragedy of the high seas commons. Furthermore these norms have a 'hobbling' effect on RFMOS and coastal states alike, and leave them almost powerless to ensure flag-state compliance with their sustainable fishing measures without the consent of the flag state, and totally unable to enforce its measures directly on that flagged vessel. Thus in the absence of an express reference to the superiority of coastal state rights over those of high seas fishing states, freedom of high seas fishing prevails. However the international community armed with weaker UNCLOS obligations of conservation and co-operation and have fought the good fight, and in lightening speed have constructed a normative framework that is additional to but consistent and complimentary with the UNCLOS regime. With the use of port state measures, voluntary instruments that codify responsible fisheries practice, surveillance and the denial of the right to land IUU fish – the fight is gradually beginning to turn in favour of the international community.</p>

<p>Cilacap adalah salah satu sentra perikanan di Indonesia dengan salah satu produk utamanya adalah udang dan alat tangkap utama yang digunakan adalah trammel net. Penelitian ini bertujuan untuk menduga status tingkat pemanfaatan stok sumberdaya udang. Pengumpulan data dilakukan dengan metode survei dan studi pustaka. Analisis data melalui pendekatan model bioekonomi Gordon- Schaefer. Pemanfaatan stok udang pada tahun 2003-2011 berada di bawah kondisi tingkat kelestarian sumberdaya, sedangkan tahun 2012-2013 telah melampaui tingkat kelestarian sumberdaya. Hasil tangkapan tahun 2011 masih di bawah kondisi tingkat kelestarian sumberdaya, namun telah melampaui jumlah tangkapan yang diperbolehkan (JTB). Hasil penelitian menunjukkan bahwa status pemanfaatan sumberdaya udang terkini sudah overfishing baik secara biologi maupun ekonomi. Jika hal ini terus dibiarkan maka berpotensi merusak kelestarian sumberdaya udang dan mengancam keberlanjutan usaha perikanan tangkap udang yang menjadi mata pencaharian nelayan. Untuk itu diperlukan pengelolaan yang mengatur tingkat pemanfaatan sumberdaya udang sehingga sumberdaya udang tetap lestari dan usaha perikanan udang tetap menguntungkan nelayan.</p><p> </p><p><em>(Bio-economic Status of Shrimp Resources in Cilacap District)</em></p><p><em>Cilacap is one of Indonesian fisheries centre with shrimp as one of its main commodity with trammel net as the main fishing gear that used in the site. The objective of this study was estimating the status of shrimp fisheries in the area. Survei and literature study were used to collect data, while Gordon- Schaefer bioeconomic model was used to analyze them. Results indicated that shrimp yield in 2003-2011 was still under sustainable level; however in 2012-2013 had already exceeded it. Total production in 2011 was also still under sustainable yield but had exceeded its Total Allowable Catch (TAC). Furthermore, it was also indicated that the current status of shrimp fisheries had been overfishing both biologically and economically. This situation could not only potentially undermine shrimp fisheries sustainability but also threaten shrimp business sustainability as fishers’ livelihood if it continued. Therefore, fisheries management which manage the shrimp yield level was needed to not only keep shrimp resources sustained but also profitable for fishers.</em></p>
