Production Functions of the Norwegian bottom trawl fisheries of cod in the Barents Sea
. Catch and effort data of the cod fisheries of 18 Norwegian bottom trawlers have been obtained for the period 1971-1985. Statistical analyses have been carried out, assuming different types of production functions. Independent variables of the catch production are the per vessel trawl hours a day,...

. Catch and effort data of the cod fisheries of 18 Norwegian bottom trawlers have been obtained for the period 1971-1985.

Per day biomass estimates have been calculated by polynomial interpolation of the per year estimates of the International Council for the Exploration of the Sea (ICES).
