Spawning stock biomass (SSB) is often used to give a measure of the size of particular fish stocks. Figures for the SSB of major North sea stocks are available from the most recent scientific advice provided by the International Council for the Exploration of the Sea (ICES). These are given in the following table.
Stock SSB (Thousand tonnes) Cod 70.7 Haddock 212 Plaice 265 Hake 151.4 Sole 28
Stock SSB (Thousand tonnes)
It should be noted that hake caught in the North sea are considered to form part of a biological stock (“Northern Hake”) that covers a much larger area, including the Bay of Biscay, the Western approaches, the Irish Sea and West of Scotland.
