The methods and gears used to capture fish affect how many unwanted fish are captured (bycatch) and can disrupt other ecosystem components. Bycatch and discards significantly impede the sustainable use of living marine resources that are captured by commercial fisheries. To minimize unintended impacts on the environment, commercial fisheries should strive to improve selectivity to reduce the bycatch and discards of non-target species, as well as undersized commercial species. Research is exploring other effects of fishing gears on ecosystems, such as habitat damage and ghost fishing of derelict fishing gear, and developing new technologies to minimize such unintended impacts. This workshop will focus on the linkages between fishing technologies, ecosystems and ecosystem-based management, as well as on recent methodologies to reduce unintended effects of fishing. Particular emphasis will be placed on studies that have changed commercial fishing practices.
