Near-bottom sampling with bottom and pelagic trawls

, 1987
The Institute of Marine Research, Bergen, has carried out combined bottom trawl and acoustic surveys for cod and haddock in the Barents Sea - Svalbard area since 1981. These investigations have demonstrated clearly that the currently applied survey methods considerably underestimate the young age groups of cod.

Recompression Improves Release Success in Pollack (Pollachius pollachius): A Step Towards Assessing Post Release Mortality in a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release.

Translating Ecological Integrity terms into operational language to inform societies

, 2018
It is crucial that societies are informed on the risks of impoverished ecosystem health for their well-being. For this purpose, Ecological Integrity (EI) is a useful concept that seeks to capture the complex nature of ecosystems and their interaction ...

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks

Fisheries Management and Ecology, EarlyView.
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

Decrease in water clarity of the southern and central North Sea during the 20th century [PDF]

, 2015
Light in the marine environment is a key environmental variable coupling physics to marine biogeochemistry and ecology. Weak light penetration reduces light available for photosynthesis, changing energy fluxes through the marine food web.
