Abstract

The sensitiveness of different demersal and pelagic fish species of 70 hauls in the North and Baltic Sea in water depths of 60 to 250 m and 15 to 80 m, respectively, amount of catch of 100 to 3500 kg and trawling times of 0,5 to 6 h on board of the FRV “Walther Herwig III” was investigated. Some demersal fish species , e.g. saithe (Pollachius virens), were even still sensitive, when caught at a water depth of 250 m at a trawling time of 1,5 h. Generally the number of sensitive fishes was reduced with increasing water depth, amount of catch, trawling time and following storage of the catch on board. Among demersal fishes the species without swimbladder and flat fishes were clearly more resistent to mechanical stress. On the contrary, pelagic fish species were generally less robust. After trawling times of 2 h no sensitive animals were observed. In some fisheries there are mixed catches of demersal and pelagic fish species with different sensitiveness. In commercial fisheries, there is therefore – under animal welfare aspects – for the time being, no prospect for an improvement of the catching and slaughtering procedure on board
