In order to conclude on the total impact of trawling, an extensive mapping of fishing effort and bottom habitat would be necessary. In general, the response of benthic organisms to disturbance differs with substrate, depth, gear, and type of organism (Collie et al. 2000). Seabed characteristics from the Barents Sea are only scarcely known (Klages et al. 2004) and the lack of high-resolution (100 ...

Minke whale
The management of this species is based on the Revised Management Procedure (RMP) developed by the Scientific Committee of the International Whaling Commission. The inputs to this procedure are catch statistics and absolute abundance estimates. The present quotas are based on abundance estimates calculated from surveys conducted in 1989, 1995, 1996–2001 and 2002–2007.

Northern shrimp

The 2008 stock assessment indicated that the stock has been exploited in a sustainable manner and has remained well above precautionary reference limits throughout the history of the fishery. The advised TAC (quota) for 2009 is 50,000 tonnes.

Fisheries are meant to influence the ecosystem by removing sustainable quantities of fish as food for humans. The fishery is, however, not considered sustainable if it impairs the recruitment of the fish stocks. Single species management often focuses on measuring the status of the fishery in relation to benchmarks called biological reference points (BRPs). BRPs for single species management are u...
