The effects of hook and bait sizes on fishing efficiency and size composition of cod (Gadus morhua), haddock (Melanogrammus aeglefinus) and wolffish (Anarhichas lupus) were investigated in a designed experiment in the Icelandic longline fishery. Five hook sizes, EZ 10-14, and two bait sizes, ~10 and 30g, were compared. The bait was Saury (Cololabis saira). Bait sizes affect catch rates and size selection in longline fishery for haddock, cod and wolffish. Higher catch rates of haddock were obtained with small bait, but large bait caught cod and wolffish more effectively. The proportion of fish caught with large v.s. small bait increased significantly with fish size for all three species, and the relationship can be described by a sigmoid shaped curve. Smaller hooks result generally in higher catches, but ... Conference Object Gadus morhua DataCite Metadata Store (German National Library of Science and Technology) |
