This survey was undertaken by Cefas as part of the Blackwater Herring Survey
(FSS: INA K HER);
A series of cruises carried out from 1989 to 2009 each November on the INA-K
in the Thames Estuary. The aims of which were to assess the state of herring
(*Clupea harengus*) stocks through measurements of length samples and by
ageing a stratified selection of fish. The latter was also to determine the
stock split between North Sea and Thames fish as there is a great deal of
mixing of stocks in the area. Stock identification was done by a combination
of first year growth observed in the otolith and the maturity stage of the
fish.
Survey took place between 14/11/1992 and 22/11/1992 on INA K
Equipment used during this survey :
- Larson Sprat Trawl
Survey operations were undertaken on 25 stations
1 different species were caught on this survey

A Larson Sprat Trawl was used at 36 prime stations spread throughout the
estuary. 1987-2009. Survey results were used to review the Total Allowable
Catch (TAC).
Species and Gear codelists are available via the additional information source
field.
Sampling on the surveys concentrated only on pelagic species.
