Annual survey in a series of Fisheries Science Partnership (FSP) surveys of
cod, haddock and whiting in the Irish Sea that commenced in spring 2004, and
evaluates the time-series of data on catch rates, distribution and age
composition in the western (commercial whitefish otter trawler) and eastern
Irish Sea (midwater (semi-pelagic) trawler).

series
The surveys were designed to achieve full coverage of potential cod, haddock
and whiting habitats within the area of the main roundfish fisheries of the
Irish Sea, while placing additional trawling effort in areas expected to have
the greatest densities of cod, haddock or whiting). In order to provide
adequate spatial coverage the Benaiah IV survey area was divided into blocks
of 15 minute (latitude) by 20 minute (longitude), with the intention to make
one tow in each block. Similarly, the Isadale survey was divided into blocks
of 10 minute (lat) by 20 minute (long.). The different block size for the two
surveys reflects the different anticipated average tow durations of the two
vessels (nominally 6 h for Benaiah IV and 4 h for Isadale). Additional tows
were permitted in rectangles where high densities of cod, whiting or haddock
were anticipated. The number of additional tows per rectangle was expected to
vary depending on the abundance of cod in each rectangle, up to a maximum of
two additional 6-h tows for Benaiah IV and three additional 4-h tows for
Isadale. Tows by Benaiah IV in the Clyde closure were restricted to 18 hours
of fishing in total (3 x 6h tows) under the conditions of the permission given
by the Scottish authorities.
