  • Make it simpler and better: T90 codend improves size selectivity and catch efficiency compared with the grid-and-diamond mesh codend in the Northeast Atlantic bottom trawl fishery for gadoids 

    Brinkhof, Jesse; Larsen, Roger B.; Herrmann, Bent (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-08)
    The use of a sorting grid followed by a size-selective codend with minimum 130 mm mesh size is compulsory in the Northeast Atlantic demersal trawl fishery targeting cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and saithe (Polachius virens). However, sorting grids cause some disadvantages, which possibly can be solved by removing the grid and improving codend selectivity, thus making the ...
