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 24/09/1984 and 27/09/1984 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 35 stations
42 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.
