Summary

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 10/11/2006 and 21/11/2006 on INA K
