AbstractChina (herein referred as China’s mainland, and excluding Hong Kong, Macau and Taiwan) is the largest contributor to global seafood production. While China’s marine fisheries have been extensively documented, there is a gap in systematically quantifying production of its marine fisheries and the different challenges confronting them at the provincial level. We addressed this gap in spatial detail by providing a review that compares and contrasts the exploitation history of China’s fisheries at both the national and provincial levels based on official statistical data. We expanded upon this to explore aspects of bio-socio-economic challenges faced by the country’s 11 fishing provinces. Our analysis suggested that significant increases in domestic marine catches in China have been accompanied by escalating fishing power, which has had differential impacts at the provincial scale. Catch per unit effort (CPUE) sharply declined at both the national and provincial scales, and many traditionally targeted demersal fish stocks showed clear downward trends in terms of catches. The 11 fishing provinces in China can be grouped into four clusters with distinct biological, social, and economic attributes. Targeted measures are recommended accordingly when implementing fisheries management measures for each specific fishing province in order to deliver an overall improvement in the sustainability of China’s marine fisheries.

Marine Resource Management

China’s 13th Five-Year Plan, launched in March 2016, provides a sound policy platform for the protection of marine ecosystems and the restoration of capture fisheries within China’s exclusive economic zone. What distinguishes China among many other countries striving for marine fisheries reform is its size—accounting for almost one-fifth of global catch volume—and the unique cultural context of its economic and resource management. In this paper, we trace the history of Chinese government priorities, policies, and outcomes related to marine fisheries since the 1978 Economic Reform, and examine how the current leadership’s agenda for “ecological civilization” could successfully transform marine resource management in the coming years. We show how China, like many other countries, has experienced a decline in the average trophic level of its capture fisheries during the past few decades, and how its policy design, implementation, and enforcement have influenced the status of its wild fish stocks. To reverse the trend in declining fish stocks, the government is introducing a series of new programs for sustainable fisheries and aquaculture, with greater traceability and accountability in marine resource management and area controls on coastal development. As impressive as these new plans are on paper, we conclude that serious institutional reforms will be needed to achieve a true paradigm shift in marine fisheries management in China. In particular, we recommend new institutions for science-based fisheries management, secure fishing access, policy consistency across provinces, educational programs for fisheries managers, and increasing public access to scientific data.

A 1977 exploratory survey of subtidal clam resources in the southeastern Bering Sea revealed extensive concentrations of Alaska surf clams (Spisula polynyma) along the north coast of the Alaska Peninsula. Using east coast hydraulic clam harvesters, subsequent 1977 and 1978 stock assessment surveys delineated a geographically isolated stock with an estimated exploitable biomass of 329 000 ± 52 000 t and conservatively calculated potential annual yield of 25 017 t (maximum sustainable yield) of whole clams. Production fishing trials at 13 sites in 1978 produced an average catch per unit effort of 815 kg/h with a 1.84-m-wide clam harvester.Life history studies indicated the species is long-lived (25 yr), slow growing (K = 0.135), fully recruited to the spawning population at 8 yr of age, subject to low natural mortality (conservatively calculated as M = 0.19), and attains maximum cohort biomass at ages between 9.4 and 13.0 yr. Biological rationale for management measures is presented.Key words: population assessment, sustained yield, surf clams, Alaska

AbstractThe 1995 UN Straddling and Highly Migratory Fish Stocks Agreement is designed to implement the management principles of the LOS Convention applicable to these stocks. This contribution focuses upon those aspects of the 1995 Agreement related to surveillance and enforcement, dispute settlement and the role and competence of regional fisheries management organisations (RFOs). The Agreement seeks to delegate fisheries management authority over straddling stocks to the RFOs. A key issue that will confront an RFO will be compatibility of management measures inside and outside the 200-nautical mile zone. An RFO will have to choose between a "top down" (the RFO managing the entire stock) or a "bottom up" (the coastal state having independent authority within 200 nautical miles) approach. While the 1995 Agreement is careful not to trample upon coastal state jurisdiction within 200 nautical miles, the preferred resource management approach supported by the 1995 Agreement and this contribution is the "top down" model.

AbstractThe SEAFO Convention, signed in April 2001, is one of the first new conventions to create a regional fisheries management organisation since the adoption of the UN Fish Stocks Agreement. The negotiating history of the convention, and the way the SEAFO participants dealt with key issues in the international fisheries management, illustrates effective use of the Agreement, even before the entry into force of the Agreement, and while it remains uncertain whether all SEAFO participants will also be bound by the Agreement when it is in force. The SEAFO Convention also deals with discrete high seas stocks, not covered by the Agreement.

AbstractThis paper deals with decision-making processes within those regional fisheries management organisations (RFMOs) with the capacity to adopt management measures respecting either straddling or highly migratory fish stocks. The perception is that the decisions emanating from RFMOs are not achieving the goal of sustainable management of the fish stocks. Concerns raised in this regard are the perceived: non-adherence of RFMO decisions to science; lack of timeliness in making decisions; ability of RFMO members to avoid certain decisions; and adoption of management decisions that are not sufficiently rigorous. This contribution does not seek to evaluate the validity of the perception, rather it explores the manner in which RFMO conventions (the constitutive texts of RFMOs) deal with the decision-making process by looking at the trends within RFMOs, the challenges that exist and suggests ways to meet the challenges.

The article analyzes the importance of marine fisheries in the area covered by the Svalbard Treaty of 1920, both for Russia and for other countries. The information on the history of the discovery and on marine living resources exploitation in the area is provided. The significant contribution of Russian scientists and fishermen to the trade is emphasized. Effective cooperation between Russia and Norway on fish resources monitoring and fisheries management in the framework of the SRNC was noted. At the same time, the disagreement between Russia and Norway regarding the introduction by Norway of a 200-mile fish protection zone around Spitsbergen necessitated Russia to adopt appropriate measures to ensure the national fisheries interests in the area.

Tuna Fishery

<p>ABSTRACT<br /><br />Tuna is an important fish commodity in Southeast Sulawesi. It valued as an export and interisland trade product as well as an important component of local fish consumption for coastal community around Southeast Sulawesi Waters (PSST). Indonesian fisheries management is currently adopting the concept of ecosystem approach to fisheries management (EAFM). EAFM implementation in Indonesia has continued by indicators establishment to assess the sustainability performance of fisheries. Catch per unit effort standard (Standard CPUE) and juvenile composition were implemented as indicators to assess resource sustainability. Data limitations are one of the issues in fisheries management at this time, however, management efforts remain to be implemented by utilizing the best available data. This study aimed to derived recent ten years coverage of standard CPUE and it trends as well as juvenile proportion in tuna fishery based on statistical data and field observation. Assessment results show that Standard CPUE in 2014 was 0,31 tons per trip and tends to increase in year coverage, while juvenile composition was 48,6%. Based on these results, the tuna fishery in Southeast Sulawesi is still sustainable. However, there is a need to have further control and monitoring, especially on a fishery that caught tuna under Lm. Management measure has to be selected carefully in line with social economic aspects of tuna fishery in this area.<br /><br />Keywords: EAFM, juvenile proportion, Standard CPUE, tuna</p><p>-------<br /><br />ABSTRAK<br /><br />Tuna merupakan komoditas perikanan penting di Sulawesi Tenggara baik sebagai produk ekspor, perdagangan antar pulau maupun pemenuhan kebutuhan lokal bagi masyarakat pesisir di perairan bagian selatan Sulawesi Tenggara (PSST). Untuk mempertahankan keberlanjutan perikanan tuna di daerah ini maka perlu adanya suatu upaya pengelolaan komprehensif yaitu pengelolaan perikanan dengan pendekatan ekosistem atau Ecosystem approach to Fisheries Management (EAFM). Implementasi EAFM di Indonesia terus dikembangkan dengan tersusunnya indikator penilaian kinerja pengelolaan. Tangkapan per Unit Upaya atau Catch per Unit Effort (CPUE) dan komposisi yuwana merupakan bagian dari indikator EAFM Indonesia khususnya dalam domain sumberdaya. Penelitian ini bertujuan untuk memperoleh nilai CPUE baku dan kecenderungannya selama sepuluh tahun terakhir, dan proporsi yuwana berdasarkan data statistik perikanan yang diintegrasikan dengan data yang diperoleh melalui pengamatan, wawancara dan pengisian kuesioner dengan pemangku kepentingan terkait. Hasil penilaian menunjukkan bahwa CPUE baku tahun 2014 adalah 0,31 ton/trip dengan kecenderungan meningkat, sedangkan komposisi yuwana adalah 48,6%. Berdasarkan nilai CPUE baku dan proporsi yuwana, maka kinerja perikanan tuna Sulawesi Tenggara masih dinilai baik. Perlu adanya upaya pengendalian dan pemantauan lebih lanjut terutama pada perikanan yang menangkap yuwana tuna. Namun demikian, pemilihan tindakan pengelolaan harus dilakukan secara hati-hati dengan memperhatikan pemenuhan kebutuhan sosial ekonomi lainnya dari perikanan tuna di daerah ini.<br /><br />Kata kunci: EAFM, proporsi yuwana, CPUE baku, tuna</p>

Conservation, like beauty, is clearly in the eye of the beholder. The lack of a clear definition of what is meant by the term conservation, however, may encourage misconceptions about the degree to which biological objectives can be traded off against pressing economic and social objectives. Our purpose is to promote a dialogue about the meaning and practice of conservation, which might lead toward consensus on essential biological objectives. We present a brief history of the philosophical evolution of the term conservation and offer a definition of conservation based on the argument for an ecological ethic. This ethic requires that human benefits be derived in a sustainable manner and recognizes that human uses need to be reconciled with intrinsic and necessary ecosystemic functions and structures. We then present a preliminary set of operating principles applicable to the management of fish stocks that are consistent with an ecological or ecosystemic view of conservation. By proposing a set of conservation principles for fisheries management we hope to initiate a debate about just what those principles ought to be.

The Great Leap Forward

In 1949, at the end of a long period of wars, one of the biggest challenges facing leaders of the new People's Republic of China was how much they did not know. The government of one of the world's largest nations was committed to fundamentally reengineering its society and economy via socialist planning while having almost no reliable statistical data about their own country. This book is the history of efforts to resolve this “crisis in counting.” The book explores the choices made by political leaders, statisticians, academics, statistical workers, and even literary figures in attempts to know the nation through numbers. It shows that early reliance on Soviet-inspired methods of exhaustive enumeration became increasingly untenable in China by the mid-1950s. Unprecedented and unexpected exchanges with Indian statisticians followed, as the Chinese sought to learn about the then-exciting new technology of random sampling. These developments were overtaken by the tumult of the Great Leap Forward (1958–1961), when probabilistic and exhaustive methods were rejected and statistics was refashioned into an ethnographic enterprise. By acknowledging Soviet and Indian influences, the book not only revises existing models of Cold War science but also globalizes wider developments in the history of statistics and data. Anchored in debates about statistics and its relationship to state building, the book offers fresh perspectives on China's transition to socialism.
