DOCUMENT SARM-10-14b VERTICAL DISTRIBUTION OF 17 PELAGIC FISH SPECEIS IN THE LONGLINE FISHERIES IN THE EASTERN PACIFIC OCEAN

S Pelagic deep longline was widely used in targeting tunas of high economic values with other fish species caught incidentally as bycatch. Identifying characteristics of vertical distribution of fish species that interact with longline can provide critical information needed for the development of effective measures to mitigate bycatch species and is essential for ecosystem conservation. Much w...

Conservation Hotspots for the Turtles on the High Seas of the Atlantic Ocean

Understanding the distribution of bycaught sea turtles could inform conservation strategies and priorities. This research analyses the distribution of turtles caught as longline fisheries bycatch on the high seas of the Atlantic Ocean. This research collected 18,142 bycatch observations and 47.1 million hooks from large-scale Taiwanese longline vessels in the Atlantic Ocean from June 2002 to De...

Trade-offs among catch, bycatch, and landed value in the American Samoa longline fishery.

The interspecific preferences of fishes for different depths and habitats suggest fishers could avoid unwanted catches of some species while still effectively targeting other species. In pelagic longline fisheries, albacore (Thunnus alalunga) are often caught in relatively cooler, deeper water (>100 m) than many species of conservation concern (e.g., sea turtles, billfishes, and some sharks) th...

Deep-water longline fishing has reduced impact on Vulnerable Marine Ecosystems

Bottom trawl fishing threatens deep-sea ecosystems, modifying the seafloor morphology and its physical properties, with dramatic consequences on benthic communities. Therefore, the future of deep-sea fishing relies on alternative techniques that maintain the health of deep-sea ecosystems and tolerate appropriate human uses of the marine environment. In this study, we demonstrate that deep-sea b...

Effectiveness 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...
