| Abstract |
A resumé is given of the sampling techniques applied in juvenile flatfish research in the countries around the North Sea in the course of time with the emphasis on small trawl nets. A preliminary comparison of the relative efficiencies of otter-trawl and beam-trawl under different environmental conditions is presented. Beam-trawls show a higher and less variable efficiency than otter-trawls. The fixed width of a beam-trawl may be an important factor. Based on these results, a standardization of juvenile flatfish sampling techniques is suggested, based on the 1-m and 2-m beam-trawl. |
