The introduction of a long-term management plan for the cod socks by the International Baltic Sea Fishery Commission (IBSFC) to ensure stable and high yields and to conserve the fish stocks of the Baltic demands certain conservation measures. One is the use of the Total Allowable Catches (TACs) based on precautionary approches. In addition the exploitation pattern and the selectivy of trawls shall be improved to increase the spawning stock biomass and to reduce the presently high discard rates. The contributation demonstrates by means of model calculations for the cod stock of the ICES Sub-divisions 22 to 24 ( Western Baltic ) the short- and long-term effects of an improvement of the trawl selectivity on stock size, yields and profit.
