The invention relates to a trawl with a special sorting net which can carry out sorting to a higher degree than known nets, hereby avoiding unnecessary and undesired catch and thus the losses connected herewith. A conventional trawl has been compared with the same trawl provided with the special sorting net. With the known trawl, the undesired catch was 70 %, while the new gave an undesired catch of only 1 %. |
