1. 1. Size Selection of Fish in the Trap Fisheries of the Baltic and Bothnian Seas

   Författare :Mikael Lundin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : A sustainable fishery in the Baltic Sea requires fishing gear that fishes selectively and at the same time excludes raiding seals. A successful type of trap recently developed in response to the seal problem is the pontoon fish chamber, which significantly decreases damage to gear and catch losses caused by grey seals. LÄS MER
