Gillnet Selectivity In The Fishery For Greenland Halibut In East Greenland

1997
No abstracts are to be cited without prior reference to the author.Catches of Greenland halibut in East Greenland and Iceland have reached a considerably high level in the last decade due to increased effort mainly by trawlers. Associated with these high catches are a steady decrease in SSB towards a critical low level.

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, 2014.

2015
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. 2014). There are currently about 500 total directed and incidental shark permits issued in the US Atlantic and Gulf of Mexico, while the ...

A commercial fisheries production function : the Skeena River sockey salmon gillnet fishery

2011
The production functions commonly suggested in the fishery bio-economic literature are reviewed, and modifications are suggested to take into account direct and indirect gear externalities and gear saturation effects in a salmon gillnet fishery. This suggests a daily production function of the Cobb-Douglas variety, tested on Skeena River sockeye salmon

Gillnet fisheries as a major mortality factor of Magellanic penguins in wintering areas

Marine Pollution Bulletin, 2011
The incidental capture in fisheries is probably the main conservation problem affecting seabirds. While the capture of albatrosses and petrels on longline hooks is well-known worldwide, the bycatch of diving seabirds in gillnets is an overlooked conservation problem.

Bayesian inference and assessment for rare‐event bycatch in marine fisheries: a drift gillnet fishery case study

Ecological Applications, 2015
Fisheries bycatch is a global threat to marine megafauna. Environmental laws require bycatch assessment for protected species, but this is difficult when bycatch is rare. Low bycatch rates, combined with low observer coverage, may lead to biased, imprecise estimates when using standard ratio estimators.
