1. Selectivity of commercial and research trawls in relation to krill

   / Description:  This paper describes the results of fishing a single krill aggregation with a commercial trawl ... RT 72/308 and an Isaacs-Kidd midwater research trawl (IKMT). The commercial trawl catches contained ... more large krill (35-58 mm) than catches of the research trawl (30-54 mm). The maximum difference in ... krill length composition was observed between catches made by the research trawl, while in commercial ... m along the belly line. The trawl bag has no rope or large-mesh sections. Therefore, the effective ...
