Травмирование и выживаемость балтийской сельди, прошедшей сквозь ячею кутка трала
In the years 1973 and 1974 a complex of investigations was conducted on the degree of injury and the chances of survival of Baltic herring after penetrating the meshes of the codends. The degree of injury was studied under real trawl fishery conditions by applying biochemical analytic methods. The chances of survival were studied on test and control fishes (which did not penetrate the meshes of the net) in cages and also after the return of tagged fish. It was found that the mortality caused by injuries does not surmount 3 percent; the remaining fishes are viable.
