Title

1982 - 2004 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Western Celtic Sea Groundfish Survey, Q1 (FSS: WCGFS)

Abstract

Surveys carried out to investigate the distribution and abundance of juvenile mackerel. Two surveys per year in March and December. Station, catch, length (all species) and biological data (selected species) are collect using research vessels. The standard bottom trawl used on these surveys was a modified Portuguese High-headline Trawl fitted with 14” rubber bobbins on the groundrope and a bunt tickler chain. The codend was fitted with a small-mesh liner (nominal diagonal stretched mesh 20 mm). The standard haul duration was 60 min and trawling was restricted to daylight hours. Fixed station positions were used and for analytical purposes

Lineage

Fishing over an allocated area of the western English Channel and Celtic Sea using a standard grid. The objectives of the survey were as follows: 1. To monitor changes in the distribution, abundance and size/age structure of fish populations within the survey area. 2. To provide time-series of indices of abundance for inclusion in scientific assessments of the main commercial species. 3. To provide information on the biology and ecology of fish species in the survey area.
