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.

Equipped with type AEM-RS electromagnetic current meter, the buoy provided effective technical platform for on-site rapid monitoring of the ocean current. Performance index and usage in the ocean current buoy of AEM-RS was introduced. Ultrasonic cleaning method in seawater was developed for preventing AEM-RS from biofouling. Ocean current data can serve for oceanographic research and marine resource exploitation.

The Schaefer-Gordon model of fisheries management does not adequately predict the state of stocks or the behavior of fishermen. In any scientific discourse, this should call the basic assumptions into question. I review the challenges to the model's biological assumptions and argue that its economic assumptions are also flawed. I review the approach developed by A.V. Chayanov for studying peasant economies in conjunction with comparative data on other fisheries and data from Mississippi Shrimpers to show that Chayanov's model characterizes the shrimpers of Mississippi. From the comparative and ethnographic data, I conclude that fishermen do not operate as firms. This further calls into question the adequacy of the current fisheries management model and raises the question of how and why such an inadequate model is perpetuated.

Technological change in the UK herring industry took place rapidly after 1965, due in part to the active encouragement encouragement given to fishermen to switch from driftnetting to pelagic trawling and purse-seining. The adoption and diffusion of these modern methods of capture stimulated a major expansion of output, but this very success was undermined by the depletion of the fish-stocks on which the industry depended. In the case of the West of Scotland herring fisheries, which were especially important to UK fishermen, the decline in fish-stock biomass caused vessel catch-rates to fall after 1973. The failure of international fisheries management, which acted as a permissive factor in the intensification of fishing effort, also had important economic implications as it resulted in the dissipation of resource-rent. The Authors calculate that the maximum sustainable ‘rent’ which could have been generated from the West of Scotland herring fishery was approximately £14 millions per annum at 1976-equivalent prices.The resource-rent effectively financed the overcapitalization of the fleet and the decline which followed, and it is the speed with which this occurred that most distinguishes the herring fishery from others where technological change has taken place. The article concludes by arguing that, although the UK public authorities (notably the Herring Industry Board) might reasonably be criticized for pursuing a development strategy which resulted in economic and biological over-fishing, the international regime of fisheries management which prevailed at the time gave them little choice but to adopt a pro-active approach to technical innovation.

Legislated marine "protected" areas are now widely distributed throughout tropical and temperate waters, but the nature of human activities actually restricted in any area varies. This ambiguity about what "protected" means has resulted in contradictory claims as to both the benefits and costs of marine protected areas. Here, we give our perspective on the current status of marine resource protection in Canada in general and British Columbia in particular. We first describe and discuss the history of Canadian marine protected areas established to date. Many areas are claimed to be protected, with little understanding by either the general public or even most marine resource experts as to what human activities are actually regulated by legislative designations. Second, we present an overview of biological reasons and objectives for marine protected areas, followed by a review of both the conservation and fisheries management effects and implications resulting from effective renewable resource protection. Finally, we propose a unique qualitative scheme for classifying and describing marine protected areas of different types to determine relative measures of protection.
