1987 - 2009 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Blackwater Herring Survey (FSS: INA K HER)
Thames Herring Survey
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.

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.
