A Study of the Relationship between the Water Temperature and the Concentration of Cod in West Greenlands Waters
MetadataVis full innførsel
The relation between catch of cod/per unit effort and temperature in West Greenland waters has been studied by material from bottom long line fishing experiments and from official fishery statistics. The experiments have been carried out during June-August by Norwegian commercial fishing vessels in 1949-1950, 1953-1955 and 1958 and by Norwegian research vessels in 1956 and 1959. When the data from subdivisions 1B, 1C and 1D of Subarea 1 of the ICNAF Convention Area from more years were considered, the stock size was taken into account. This involved only smaller differences in the cod/temperature relation, and the highest yield was obtained at the temperature interval 0.75-3.24° C.
