FSP Western cod

Abstract

The second survey of three in a series of FSP surveys of cod in the Bristol Channel and Celtic Sea. The first two surveys took place in spring 2004 and 2005 on FV Our Josie Grace, a commercial trawler based in Ilfracombe. Programme 7 in 2006 used the same vessel for 20 days between 5 February and 17 March. Tows were carried out in and close to the three ICES rectangles closed to fishing in spring, and in the Bristol Channel, using twin-rig and single-rig nets with 85mm codends. The objectives of the 2006 FSP survey were to investigate the potential of the western cod FSP survey for providing time-series data on abundance and population structure of cod, and to examine the distribution of a range of species in and near the closed rectangles.

Quality and validity

Lineage

Sampling of all catches was carried out using standard methods employed by CEFAS. This entailed recording of the numbers and lengths of all the large or unusual fish that stand out from the rest of the catch, and sorting, counting and measuring a known fraction of the remaining catch of smaller fish. Numbers in the sample were then raised up to total numbers in the haul. The total catches of hauls 11-15, for which only one net of the twin trawl was sampled, were estimated by doubling the catch recorded for the net that was sampled. Data were recorded separately for fish discarded and retained for landing. Otoliths from samples of cod, haddock and whiting were taken to determine the age of the fish, and to allow the age composition of the catches to be calculated. Weighing facilities were not available on any of the vessels.
