DOI: 10.1016/j.fishres.2020.105724
Abstract: Abstract Size-selective grids in the Barents Sea trawl fisheries have demonstrated large variation in sorting capacity. When combined with dynamic catch-control systems for regulating catch quantity, surplus fish are washed out at the surface. The… read more here.

DOI: 10.3390/jmse11051026
Abstract: Codends are the posterior components of trawl nets that collect the catch and play a crucial role in the selectivity process. Due to the accumulation of catch and the variety of catch types, the quality… read more here.
