France lauds implementation of fising area ban on reducing dolphin bycatch

 

 

 

A one month cessation of fishing, including the provision of 80% ib lost revenues to fishermen, resulted in keeping the industry alive while reducing thousands of dolphin deaths.

An overview on elasmobranch release as a bycatch mitigation strategy

Submitted by allykristan on

This study compiled data from National and Regional Plans of Action (POAs) and Regional Fishery Management Organizations (RFMOs) to investigate whether commercial fisheries practice the release of live sharks and rays caught as bycatch. Results indicate that onboard releases are cited in some POAs and RFMO recommendations, the measure has only voluntary adherence and is not considered priority. The authors call for a change in the perception of live elasmobranch releases as a conservation strategy.

Harnessing stakeholder knowledge for the collaborative development of Mobulid bycatch mitigation strategies in tuna fisheries

Submitted by allykristan on

The present study was designed to incorporate stakeholder input and fisher expertise in the design of mobulid (mantas and devil rays) bycatch technology in large-scale tuna purse seine fisheries operating in the EPO (Eastern Pacific Ocean). Surveys and focus groups of fishers suggested that the primary obstacles to mitigating mobulid bycatch are 1) inability to sight them before capture, 2) lack of appropriate response equipment on board, and 3) the difficulty of releasing large individuals. Many suggestions were made for both pre-capture and post-capture bycatch mitigation strategies.
