An attempt to estimate food biomass eliminated annually by the cod (Gadus morhua L.) population in the Baltic, based on studies in 1977-1982
Daily coefficients obtained from long-term studies on stomach content of cod feeding within subareas 25 and 26 are compared with ICES data on the biomass of the stock inhabiting subareas 25-32. The total biomass of food consumed annually by the stock is calculated as well as the biomass of food (and...

| Summary: | Daily coefficients obtained from long-term studies on stomach content of cod feeding within subareas 25 and 26 are compared with ICES data on the biomass of the stock inhabiting subareas 25-32. The total biomass of food consumed annually by the stock is calculated as well as the biomass of food (and its components) eaten by cod in various age classes. The values are calculated separately for each year within 1977-1982, 6-yr means being given as well. |
