Assessing the effectiveness of an electrical stunning and chilling protocol for the slaughter of Atlantic mackerel (Scomber scombrus)
Anders, Neil; Roth, Bjørn; Grimsbø, Endre; Breen, Michael (Journal article; Peer reviewed, 2019)Inducing unconsciousness in fish using electrical stunning prior to slaughter may improve fish welfare and fillet quality if such practises can be disseminated into wild capture fisheries.

Tveit, Guro Møen; Anders, Neil; Bondø, Morten Steen; Mathiassen, John Reidar Bartle; Breen, Michael (Peer reviewed; Journal article, 2021)Wild capture can be stressful for fish. Stress has the potential to induce mortality in released unwanted catches or negative flesh quality consequences in retained ones. Such effects compromise sustainable natural resource ... -
Behavioural and welfare implications of a new slipping methodology for purse seine fisheries in Norwegian waters
Anders, Neil; Breen, Michael; Saltskår, Jostein; Totland, Bjørn; Øvredal, Jan Tore; Vold, Aud (Journal article; Peer reviewed, 2019)The release of unwanted fish from purse seines whilst still in the water is termed slipping and may lead to significant mortality following release.

Behavioural responses of krill and cod to artificial light in laboratory experiments
Utne-Palm, Anne Christine; Breen, Michael; Løkkeborg, Svein; Humborstad, Odd Børre (Journal article; Peer reviewed, 2018)Most fishes and crustaceans respond to light, and artificial light sources may therefore be an efficient stimulus to manipulate behaviours in aquatic animals. It has been hypothesised that the catch efficiency of pots could ... -
By-catch species susceptibilities and potential for survival in Algarve (southern Portugal) deep-water crustacean trawl fishery
Adão, Ana C.; Breen, Michael; Eichert, Moritz; Borges, Teresa (Journal article; Peer reviewed, 2018)Bottom trawling for crustaceans in Portuguese coastal waters is an important fishery in terms of revenue, despite its negative impacts on deep-sea ecosystems. This fishery catches large amounts of unwanted species that ... -
