dc.description.abstract | The Institute of Marine Research studied effects of kelp (Laminaria hyperborea) harvesting on
near shore fish and crab abundance in Flatanger, Nord-Trøndelag in August 2014. Recordings
were made using fixed underwater camera systems and traditional fish and crab catching gear in
kelp harvested areas and in reference kelp beds. The methods sample different species and sizes of
fish, and supplement each other. There was a significant reduction of small cod and an increased
amount of wrasse caught in wrasse traps on the harvested field two years after kelp harvesting,
compared to pre-harvesting catches, indicating opposite effects of kelp harvesting on these groups
of fish. However, the study suffers from a relatively low number of sampling units for the preharvesting
recordings, and knowledge on the effects of kelp harvesting on fish and crab
abundances should be supplemented by future studies | nb_NO |
