In 1992 an acoustic survey in fjords and shelf areas off Finnmark and Troms, two counties in northern Norway, was made to estimate the total biomass of cod, haddoc, saithe, redfish species and herring to be 876.000 tonnes. The total biomass of cod was calculated to 112.000 tonnes. Based on otolith structures about 1/3 of the cod (34.000 tonnes) was identified as North East Arctic cod. The remaining, dominant fraction of 78.000 tonnes was coastal cod which form local stocks, according to tagging experiments performed in 1986 - 92. The biomass of other fish species were; haddock: 78.000 tonnes; herring: 470.000 tonnes; capelin: 10.000 tonnes; saithe: 181.000 tonnes and redfish: 25.000 tonnes.
