The constraint technique, i.e. using a rope between the warps, has the intention of minimizing the variability in trawl geometry with depth. Experiments with the constraint technique on two different bottom trawls used ...

A newly developed cod pot (two-chamber pot) has been tested in the VarangerfJord area as an alternative to gill-net, with the purpose to reduce the periodically large unaccounted mortality of king crab in the gill-net ...

Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that, under most circumstances, increased mortality at potential ages and sizes at maturation ...

The main aim of the ecosystem survey was to map the distribution and abundance of the young and adult stages of several demersal and pelagic fish species, and in addition to this gather information about hydrographical ...

ICES coordinated surveys are, on a non-regular basis, reviewed by parent expert groups. A potential problem is that these are often conducted by evaluators being themselves involved in the surveys, thus lacking ...
