Bycatch in gillnet fisheries – An overlooked threat to waterbird populations

Biological Conservation, 2009
Bird mortality in fishing gear is a global conservation issue and it is recognised that bycatch in industrial longline and trawl fisheries threatens several seabird species. Little is known however about the effects of bycatch in small-scale gillnet fisheries on bird populations.

Novel Tools to Reduce Seabird Bycatch in Coastal Gillnet Fisheries

Conservation Biology, 1999
Abstract: We examined several strategies to reduce seabird bycatch, primarily of Common Murres ( Uria aalge ) and Rhinoceros Auklets ( Cerorhinca monocerata ), in a coastal salmon drift gillnet fishery in Puget Sound, Washington, U.S.

A Study on Karaduvar Trammel and Gillnets Fisheries

2020
Sustainable management requires not only structural analysis but also socio-structural analysis. Therefore, structural analysis and the socio-cultural structure of the fishery need to be found out for the sustainable management for small-scale fishery of trammel nets at Karaduvar Fishermen Harbour.

Evaluating protected species bycatch in the U.S. Southeast Gillnet Fishery

Fisheries Research, 2020
Abstract Incidental capture or ‘bycatch’ of non-targeted species is a global fisheries issue that threatens ocean ecosystems and the conservation and recovery of protected species. Many protected species are at a high risk of incidental capture and mortality in commercial fisheries, which could have an impact on already decreasing populations.

Catch and bycatch in U.S. Southeast gillnet fisheries, 2016

2017
The Southeast Gillnet Observer Program has adapted to the changes of the Florida-Georgia shark gillnet fishery since the program began in 1993 (e.g. Carlson and Bethea 2007 and references therein, Mathers et al. 2015). There are currently about 500 total directed and incidental shark permits issued for the southeastern U.S.

Effect of baiting gillnets in the Canadian Greenland halibut fishery

Fisheries Management and Ecology, 2020
AbstractCatch rates were compared between gillnets with and without bait in the Greenland halibut Reinhardtius hippoglossoides (Walbaum) fishery off Baffin Island, Canada. Two different types of baiting techniques were compared: bait bags where squid were placed into 2‐mm mesh bags, and tied bait where squid were tied into meshes.

Reducing seabird bycatch in longline, trawl and gillnet fisheries

Fish and Fisheries, 2007
AbstractWith an increasing number of seabird species, particularly albatross and petrels, becoming threatened, a reduction of fishery impacts on these species is essential for their future survival. Here, mitigation methods to reduce and avoid seabird bycatch are assessed in terms of their ability to reduce bycatch rates and their economic viability ...
