Hello Mark,
In Ontario (Canada) we adopted the Nordic method (I believe this is also the EU standard?) for our biodiversity work. It works well in lakes >10ha and catches a large size range of individuals. I have attached copies (ours and the original Scandinavian versions) of the manual.
Best Wishes
George

Hi mark,
I frequently use a small beam trawl like the third model in the article and caught many three-spine stickleback and other small fish with it in different types of habitat. It is easy to use from a relatively small boat.
