Effects on individual level behaviour in mackerel (Scomber scombrus) of sub-lethal capture related stressors: Crowding and hypoxia
Anders, Neil; Howarth, Kirsten; Totland, Bjørn; Handegard, Nils Olav; Tenningen, Maria; Breen, Michael (Peer reviewed; Journal article, 2019-03-13)Stress to fish during harvest in wild capture fisheries is known to negatively influence subsequent survival in catches that are released.

Effects on schooling function in mackerel of sub-lethal capture related stressors: Crowding and hypoxia
Handegard, Nils Olav; Tenningen, Maria; Howarth, Kirsten; Anders, Neil; Rieucau, Guillaume; Breen, Michael (Peer reviewed; Journal article, 2017-12-28)The selectivity of fishing gears with respect to fish species and size is important, both for fisheries management and fishing operations. Purse seining is an efficient, environmentally friendly fish capture methodology ...
