Alternative title(s)

FSP North Sea whitefish

Abstract

One of a time-series to develop a North Sea survey to compare the catch rate of our whitefish species using an otter trawl on hard grounds and a scraper trawl on soft grounds. Detailed measurements will be made of cod, whiting, haddock and possibly plaice.

Lineage

The North Sea whitefish (NSW) survey is designed to provide a time-series of information on commercial vessel catch per unit effort from representative fishing grounds within the North Sea. Each year, data gathered by the survey are supplied to the ICES Working Group on the Assessment of Demersal Stocks in the North Sea and Skagerrak, initially for evaluating comparative catch rates at age, for example against research vessel catches, and if and when the time-series is of sufficient length, to support the estimation of stock trends. The vessel uses a combination of traditional English fishing gears appropriate to hard and soft ground in order to provide information on comparative catch rates. The tows are distributed over subareas defined to provide information on catch rate, size/age composition and species catch composition from as many different locations as feasible, given time and cost constraints, within the area where the fishery takes place, and not necessarily at constant locations each year. The size of the whole catch is recorded, but detailed measurements are made of the catches of cod, whiting and haddock, and of plaice.
