The effect of grid size on catch efficiency and by-catch in the demersal trawl fishery for Norway pout (Trisopterus esmarkii)
(Peer reviewed; Journal article, 2022)Norway pout (Trisopterus esmarkii) is caught with large trawls with small meshed codends, inevitably causing the fishery to have large by-catch issues. To reduce the amount of by-catch, a rigid sorting grid was made ... -
Quantification of gear inflicted damages on trawl-caught haddock in the Northeast Atlantic fishery
(Journal article; Peer reviewed, 2020-08)External damages are indicators of the overall quality of fish and fish welfare. Haddock is an important commercial species widespread in the North Atlantic, but few studies related to quality have been carried out on this ... -
Size selectivity and catch efficiency of bottom trawl with a double sorting grid and diamond mesh codend in the North-east Atlantic gadoid fishery
(Journal article; Peer reviewed, 2020-11)This study investigated the size selectivity and catch efficiency in the North-east Atlantic demersal trawl fishery targeting cod (Gadus morhua) and haddock (Melanogrammus aeglefinus). The use of a sorting grid followed ... -
Species separation efficiency and effect of artificial lights with a horizonal grid in the Basque bottom trawl fishery
(Peer reviewed; Journal article, 2022)Achieving effective size selectivity for different species within a fishing gear is a major challenge in mixed fisheries. Fish behaviour may be exploited to separate species into separate codends where different selective ...
