| Abstract | Bycatch has become one of the most pressing fishery management issues of our time. Bycatch, which is defined as the part of the capture that is discarded dead (Hall 1996), occurs because most fishing technologies cannot be perfectly selective in targeting the desired species. Bycatch affects nontarget fish species, juvenile target fish species, and other nonfish species (Alverson and Hughes 1996). Discarding occurs for a number of reasons: economic (low price, no market, lack of storage space, quality, high-grading), quotas are reached, or regulations prohibit the particular species, age, size, gear, or season. I Besides the issue of waste inherent in bycatch, particular concerns arise when the bycatch is a long-lived species with low reproductive rates, particularly if the species is threatened or endan gered. Bycatch ofmarine mammals, seabirds, and sea turtles is currently one ofthe significant drivers of fisheries management in several cases et al. 2000). Bycatch of particular species may have impacts on the ecosystem and biodiversity, such as removal of top-level predators or of prey. Bycatch has negative impacts on fishers as well. It can be a source of conflict, creates a bad image with consumers, leads to restrictive regulations, and can decrease profit because of the time that must be spent separating the bycatch from the fish to be retained. In addition, ifbycatch is mainly ju veniles ofthe target species, it can lead to a decline in the resource of interest. Objectives of bycatch management, therefore, can be diverse: avoiding severe depletion of a species, retaining the basic structure and functioning ofecosystems, reducing waste in fisheries, reducing interactions between fisheries, keeping fisheries open, and rebuilding depleted popUlations. |
