The aim was to provide fisheries independent abundance indices of all age groups of sole and plaice which are used in assessment working groups to tune the ICES stock assessment and to estimate recruitment. The survey was undertaken annually. Fifty eight trawl stations on the main sole grounds in the English waters of the Western English Channel were fished and sampled. Surveys were carried out on chartered commercial fishing vessels with Cefas staff on board. Survey took place between 13/10/2013 and 19/10/2013 on Carhelmar Equipment used during this survey : - Beam Trawl 4m steel commercial 3/5 link mat flip up 75mm CE 40mm liner PORT - Beam Trawl 4m steel commercial 3/5 link mat flip up 75mm CE 40mm liner STAR Survey operations were undertaken on 58 stations 113 different species were caught on this survey Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk originator Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk custodian Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk distributor Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) data.manager@cefas.co.uk owner Department for Environment, Food and Rural Affairs (DEFRA) defra.helpline@defra.gov.uk owner European Commission info@publications.europa.eu owner annually Species Taxonomy Benthos Crustacean Invertebrate Mollusc Shellfish Age Advice Indicator Management Monitoring Stock (biological) Aquatic environment Biodiversity Catchment area Coastal environment Ecosystem GEMET, version 1.0 2008-06-01 publication Biodiversity indices Fish abundance in water bodies Fish biomass in water bodies Fishery characterisation Fishing by-catch SeaDataNet P02 parameter discovery vocabulary 2011-03-25 revision Biota abundance, biomass and diversity Fish Fisheries Other biological measurements SeaDataNet P03 parameter discovery vocabulary 2011-03-25 revision Species distribution GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Infralittoral Circalittoral SeaVoX Vertical Co-ordinate Coverages 2010-05-18 revision Marine Environmental Data and Information Network MEDIN metadata record availability 2012-01-11 publication data.gov.uk MEDIN metadata record availability 2012-01-11 publication otherRestrictions noLimitations otherRestrictions Adherance to the Cefas Data access policy required.

Data were originally collected and stored in spreadsheets. All Carhelmar data is stored on the Fishing Survey System (FSS). Biological were samples returned to the laboratory fro processing and age determination as required. Data has been extensively quality checked. When the survey was undertaken by the Carhelmar (survey reference prefixed as CHMR) the catch was processed separately by port and starboard beam, but on a few occasions a catch only from the one side was processed. In 2002 and 2004 the survey was undertaken on the Corystes research vessel, (survey reference prefixed as CORY) but only the one beam was used, however this was rigged with the same gear previously used by the Carhelmar. In 2003 both vessels were used. When the survey was conducted on the Carhelmar, the processing of the catch focused on the commercial species. All commercial fish species were measured. Non-commercial species were not always identified and measured. Benthic observations were made in some of the years from the port side beam. Biological age data were collected for sole and plaice.
