The innovative construction of a specific small mesh split cover for the Baltic cod codends (T90 and BACOMA types) have been designed. Owing to that cover, it was possible, for the first time at the Baltic sea, to quantify separately the cod number escaping the codend when towing and when heaving the trawl on board. The cod escaping during heaving the trawl have their swim bladder damaged, due to decompression, and die. Until now, a percentage of such cod was an unknown value. Conducted surveys, based on 25 survey drags indicated that 36.22 % of the captured cod individuals run away during heaving operation, it is 32.97 % of a total catch weight. We called it invisible discard. Results point to the urgent need for a new approach in addressing the selectivity and discard problem during trawling operation for the Baltic cod.
