BACKGROUND Fishery management has historically been an inexact and reactionary discipline, often taking action only after a critical stock suffers overfishing or collapse. The invertebrate ornamental fishery in the State of Florida, with increasing catches over a more diverse array of species, is poised for collapse. Current management is static and the lack of an adaptive strategy will not all...

The fishery for mobulid rays, also known as devil rays, has been practiced in the Bohol Sea for over a century yet very little is known about its history and characteristics. This study provides the first detailed description of the mobulid ray fishery in the Bohol Sea, Philippines. It describes the history and evolution of the fishery from the 19th century to 2013. It characterizes the fishery...

We develop an economic model for a multi-species fishery that incorporates the spatial distribution of effort and fish stocks. Catchability coefficients and initial stocks are estimated from catch and effort data for each specific location. Vessels are allocated over space and time to locations of maximum profit which decline with harvest because of stock externalities. A supply function for la...

Regulatory efforts to reduce bycatch fulfill multiple management goals -from protecting overfished and depleted species, to preventing over-harvest of species of unknown abundance, to acknowledging that vessels using different gear types require different harvest strategies, to matching within-year harvest rates to within-year abundance and congregation habits of managed species. These goals mu...

the catch composition of the bottom trawl fishery along the coasts of karataş was evaluated in the 2002-2003 fishing season. a total of 110 species were registered, the fishes showed the highest diversity (90 species) followed by 15 crustaceans species and 5 species of cephalopods. the highest catch per unit effort (cpue) value (66.8 kg h -1 ) was recorded in september when the fishing season w...

Using individual firm data from before and after the introduction of ITQs in the multispecies Nova Scotia mobile gear fishery, data envelopment analysis (DEA) is used to examine issues relating to capacity and capacity utilization. The paper is the first to look at capacity utilization in the context of a multi-species fishery that has both ITQ and nonITQ components. The paper examines how a ch...

Effective management is necessary if small-scale fisheries, such as those found in mixed habitats including seagrass and coral reefs, are to continue providing food for many of the poorest communities of the world. Gear-based management, although under represented and under studied, has the potential to be adaptive, address multiple objectives, and be crafted to the socio-economic setting. Mana...

Although a consensus in marine science is developing on the need to adopt ecosystem-based fishery management, few studies try to quantify the contextspecific gains from implementing it. Using a multi-species bioeconomic model for a Caribbean reef community, we determine the optimal harvesting rates for predator and prey species and ask how this more comprehensive optimization differs from tradi...
