Start year 2010 End year 2012 Funding (€) € 136,000 Website https://www.fhf.no/prosjekter/prosjektbasen/900432/ Summary "By-catch of king crab is a growing problem along the coast of Finnmark, and especially in net fishing for cod, by-catch is high (Godøy et. al., 2003; Hjelset et al., 2003). The problems are greatest in Eastern Finnmark, but are spreading further west in the county.
Experiments carried out within this project show that a grooved skirt at the bottom of the net results in significantly fewer king crabs in the catch, see separate fact sheet . During the experiments, all crabs were caught on standard nets, none were caught on skirt nets. It therefore appears that the net skirts work well to avoid crabbing. Catches of cod seem to be somewhat less. The advantage of crab-free nets can still far outweigh the reduction in catch otherwise. Despite somewhat reduced fish catches and the fact that nets with grooved skirts take up considerably more space in the net bin, this can be an alternative to avoid bycatch of king crab.
Goals:
1. To develop and test cod nets that significantly reduce bycatch of king crab, while at the same time catching cod is not reduced.
2. To document the degree of wear and accumulation of bottom substrate on the test yarns, and compare this with standard yarns.
3. To assess the transfer value for bycatch of bag crab in more detail if the experiments are successful"
