| Abstract |
A standard two-metre beam trawl, frequently and commonly used in surveys of young flatfish, was modified to increase its catch efficiency by replacing the tickler chains with heavy, spiked chains. Catches of 0-group plaice were improved by a factor of almost five. Differences in catchability were found between the three species, and behavioural factors were suggested which could account for such variation. |
