to improve the selection of roundfish
Target species:

The catches of a standard 80 mm diamond mesh codend are compared with those of an 80mm square mesh codend.
Results:
The square mesh codend released more pouting than the diamond mesh codend. There were no differences in the catches of the target species, sole. There was some deformation of the square meshes.
