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.

series
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.
