Evaluation of the Effectiveness of Light Streamer Tori-Lines and Characteristics of Bait Attacks by Seabirds in the Western North Pacific
To improve the effectiveness of tori-lines it is necessary to evaluate the ability of tori-lines to mitigate seabird bycatch and determine what kind of seabird species gather during line settings, attack the bait and are incidentally caught. We conducted two experiments in the western North Pacific and examined the effectiveness for seabird mitigation of light streamer tori-lines which have no ...
متن کاملSCIENTIFIC COMMITTEE THIRD REGULAR SESSION 13-24 August 2007 Honolulu, United States of America RECORDING SEABIRD BYCATCH IN LONGLINE OBSERVER PROGRAMS WCPFC-SC3-EB SWG/WP-6
This paper discusses best practice for collecting seabird bycatch data in pelagic longline observer programs. The paper recognizes that key challenges for WCPFC include: • The levels of observer coverage needed for recording and monitoring bycatch of non-target species such as seabirds, which typically have high variability in CPUE • The need to divide observer time between a range of tasks • T...
متن کاملRelative abundance and distribution of fisheries influence risk of seabird bycatch
Fisheries provide an abundant and predictable food source for many pelagic seabirds through discards, but also pose a major threat to them through bycatch, threatening their populations worldwide. The reform of the European Common Fisheries Policy (CFP), which intends to ban discards through the landing obligation of all catches, may force seabirds to seek alternative food sources, such as bait...
متن کاملEffectiveness of tori line use to reduce seabird bycatch in pelagic longline fishing
Industrial longline fisheries cause the death of large numbers of seabirds annually. Various mitigation measures have been proposed, including the use of tori lines. In this study the efficiency of a single tori line to reduce seabird bycatch was tested on pelagic longline vessels (25-37m length). Thirteen fishing trips were carried out in the area and season of the highest bycatch rates record...
متن کاملComparing effectiveness of experimental and implemented bycatch reduction measures: the ideal and the real.
Fishers, scientists, and resource managers have made substantial progress in reducing bycatch of sea turtles, seabirds, and marine mammals through physical modifications to fishing gear. Many bycatch-avoidance measures have been developed and tested successfully in controlled experiments, which have led to regulated implementation of modified or new fishing gear. Nevertheless, successful bycatc...
