Assessing impact of fishing on growth of corkwing wrasse (Symphodus melops) and goldsinny wrasse (Ctenolabrus rupestris)
Berntsen, Vegard Omestad (Master thesis, 2022)Corkwing wrasse (Symphodus melops) and goldsinny wrasse (Ctenolabrus rupestris) are two temperate wrasse (Labridae) species that are targeted by commercial fishery due to their ability to reduce sea-lice infections. The ... -

Insights into lobster trap selectivity: exploring the role of local demography and behaviour for effective reserve monitoring
Ulset, Silje Marie (Master thesis, 2024)Human activities have a major effect on the world’s ecosystems including the marine environment, where harvesting practices often target individuals based on specific traits, resulting in selective fishing. This selective ... -
Lobster reserves as a management tool in coastal waters: Two decades of experience in Norway

Protection from fishing improves body growth of an exploited species
Sørdalen, Tonje Knutsen; Halvorsen, Kim Aleksander Tallaksen; Olsen, Esben Moland (Peer reviewed; Journal article, 2022)Hunting and fishing are often size-selective, which favours slow body growth. In addition, fast growth rate has been shown to be positively correlated with behavioural traits that increase encounter rates and catchability ... -
