    dct:description """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. The Blackwater Herring survey report can be downloaded from this record.
