Alternative title(s)

FSP Irish Sea roundfish

Abstract

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).

Quality and validity

Lineage

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.
