Warum Fischereiwissenschaftler nicht mit kommerziellen Netzen fischen

“Wrong trawl, wrong rigging – that’s why research ship cannot find cod” – in a polemic article in the April number of “Fishing News International” British fishermen accuse fishery scientists of using the wrong trawl for their bottom trawl surveys in the North Sea. They wrote the GOV is unsuited to catch cod and therefore the cod stock could be in a much better shape than assessed by the scientists. In this paper the characteristics of a scientific survey trawl and the results of comparison fishing experiments are listed.
