No abstracts are to be cited without prior reference to the author.The method is based on bottom trawl survey, for which fishing efficiency that is a relation between a number of fish caught and fish in the fished area was measured with the aid of underwater video. The method and devices (underwater video recorders) were developed and used in the experiments on fishing efficiency. The velocity and spatial orientation of G. halibut in the trawl estuary were measured analysing video records, and the concentrating factors by trawl doors and cables as well as trawl efficiency coefficient were calculated. ...
