The compound effects of changing habitats, ecosystem interactions, and fishing practices have implications for the management of Antarctic krill and conservation of its predators. For Antarctic pack-ice seals, an important group of krill predators, we estimate the density and krill consumption in theWest Antarctic Peninsula (WAP)–WesternWeddell Sea area, the main fishery region; and we consider...
This fishery was examined utilizing public records, stakeholder interviews, and operational site visits to describe the fishery for the Puerto Rico Coral Reef Advisory Committee as a first step toward development of policies for the effective management of these natural resources. The fishery is not large, including fewer than 20 licensed fishers operating primarily on the west end of the islan...
Sea turtles interact with a variety of fishing gears across their broad geographic distributions and ontogenetic habitat shifts. Cumulative assessments of multi-gear bycatch impacts on sea turtle populations are critical for coherent fisheries bycatch management, but such estimates are difficult to achieve, due to low fisheries observer effort, and a single-species, single-fishery management fo...
The transition process from the Soviet economical system to the market economy in fisheries has received relatively little attention from fisheries researchers. This study analyze how overall changes in political and economical life of Estonia during the last decade have affected the complex system of the environmental, economic, social and legal issues connected to the coastal fishery of the B...
Regional tuna fishery management organizations cannot provide specific advice to local fishery managers in small island jurisdictions. The State of Hawaii maintains time series of yellowfin tuna catches dating back to 1949, but these data have never been formally applied to evaluating the effects of the yellowfin fishery in the Main Hawaiian Islands on the local stock. I develop a new approach ...
Black Sea is one of themost severely degraded and exploited largemarine ecosystems in the world. For the last 50 years after the depletion of large predatory fish stocks, anchovy (with the partial contribution of sprat) has been acting as the main top predator species and experienced a major stock collapse at the end of 1990s. After the collapse, eastern part of the southern Black Sea became th...
This paper presents the results of a research project, which focuses on Danish fishers’ acceptance of imposed fisheries regulations and their respect for the management system. The analytical framework developed by Raakjær Nielsen (1998) and Raakjær Nielsen and Vedsmand (1999) has been applied. The research focuses on three Danish fisheries: the cod fishery in the Baltic Sea, the demersal and N...
Pursuit of the triple bottom line of economic, community and ecological sustainability has increased the complexity of fishery management; fisheries assessments require new types of data and analysis to guide science-based policy in addition to traditional biological information and modeling. We introduce the Fishery Performance Indicators (FPIs), a broadly applicable and flexible tool for asse...
We propose that rebuilding ecosystems. and not sustainability per se. should be the goal of fishery management. Sustainability is a deceptive goal because human harvesting of fish leads to a progressive simplification of ecosystems in favour of smaller. high-turnover. lower-trophic-Ievel fish species that are adapted to withstand disturbance and habitat degradation. Present fisheries management...
This paper explores the importance of a focus on the fundamental goals of resilience and adaptive capacity in the governance of uncertain fishery systems, particularly in the context of climate change. Climate change interacts strongly with fishery systems, and adds to the inherent uncertainty in those complex, interlinked systems. The reality of these uncertainties and linkages leads to a reco...
