2008 - 2008 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Survey : AMAR 1/08 (part of Solent Bass Pre-recruit Survey (FSS: SOLENT))
This survey was undertaken by Cefas as part of the Solent Bass Pre-recruit Survey (FSS: SOLENT); There are over 50 surveys in this series which began in 1983. 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 01/09/2008 and 05/09/2008 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 37 stations 60 different species were caught on this survey

The abundance, age and length of bass is recorded from fishing stations on a standard grid in Southampton Water, the Solent, and Portsmouth and Chichester Harbours using a standard bass trawl. 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.
