The aim of these are to provide abundance indices of 2-4 year old bass. The catch density of other species taken is also recorded. The survey was undertaken twice yearly during May and September for most years up to 2009. Since then one September survey each year has taken place. Survey took place between 22/09/1986 and 25/09/1986 on Angelle Marie Equipment used during this survey : - Otter Trawl Solent Bass Trawl 5 fm Headline, 6 & 8 metre bridles, 40mm Liner Survey operations were undertaken on 30 stations 39 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 Department for Environment, Food and Rural Affairs (DEFRA) defra.helpline@defra.gov.uk owner notPlanned Benthos Crustacean Shellfish Age Advice Management Catchment area Coastal environment Estuary Species GEMET, version 1.0 2008-06-01 publication Fish Fisheries SeaDataNet P03 parameter discovery vocabulary 2011-03-25 revision Species distribution GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Water column 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 Adherence to the Cefas Data access policy required.

A QA exercise has been undertaken in February 2014. The quality of sampling has improved progressively over the time series. Prior to 1995 only bass, and sometimes bream, mullet and plaice, were measured; since then most commercial species have been sampled for length. No species have ever been weighed on these surveys, but incorrect sampling process codes (e.g. weighed and counted (WC)) had been used in the original dataset. These have not been changed, but all weight values from this dataset should be ignored. No coordinate information was recorded in the log books for any of the surveys before 1995. A list of the prime stations with their position coordinates had been created manually from Admiralty charts, so there are no accurate “distanced towed” data. Stations have now been assigned validity flags. Use of an additional tow (A) has been used to indicate tows that were not part of the core survey, such as tows specifically targeting bass to tag, exploratory tows and gear comparison trials. All benthos data have now been entered onto the Fishing Survey System (FSS) database, although data recorded for benthos pre-1995 are sparse, and for some surveys (e.g. 2/2007) the benthos has been recorded in great detail due to the presence of a benthos expert from Southampton University on board. There are no age data available prior to 1994, although aggregated age length keys for some of the surveys exist in paper format. Some of the ages are missing from the samples. In these cases not all of the scale samples were analysed as it was deemed that five samples per centimetre group were sufficient. Species and Gear codelists are available via the additional information source field. MEDIN 3.1.1
