The catchability coefficient Q of cod, haddock and whiting associated with the Scottish seine-net fleet is examined. Cod and haddock show increasing catchability for the period 1963 to 1979. The rise in Q is related to the spatial distribution of the fleet as vessels increasingly fish in areas of high fish abundance. Additionally, for haddock, catchability is related to year-clas strength. The utility of catchability trends in the prediction of fishing mortality is discussed.
