Sea lice feeding behavior of wild and hatchery lumpfish (Cyclopterus lumpus) under hatchery conditions.
(Master thesis, 2022)In 2014 Norway contributed 1.2 million tons of the world production of farmed salmon. Norway is the world’s largest producer of farmed salmon, and the species is among the top five species, quantity consumed, in the major ... -
Homing ability of goldsinny wrasse (Ctenolabrus rupestris) and corkwing wrasse (Symphodus melops)
(Master thesis, 2022)Wrasse family (Labridae) are widely used as a cleaner fish in salmonid aquaculture to remove the sea lice infestation. Goldsinny wrasse and corkwing wrasse are the most used wrasse fishes in the aquaculture industry in ... -
Feltstudie av makroalgevegetasjonen på Flekkerøy, Agder
(Master thesis, 2022)Makroalger spiller en sentral rolle i kysthabitater, på grunn av deres funksjon som økosystemingeniører, konkurrenter og primærprodusenter. De danner svært produktive habitater for forskjellige samfunn, og øker den ... -
Assessing fish community dynamics in a Norwegian no-take marine reserve compared to a harvested area
(Master thesis, 2022)An ecosystem's ability to respond and maintain key functions during environmental change are largely determined by its biodiversity. As human activities continue to alter the composition of biological communities at all ... -
Ghost fishing in Raet National Park: estimating the impact on Atlantic cod and three species of wrasse
(Master thesis, 2022)Loss of fishing gear have been a problem for as long as fishing has occurred in the ocean. As modern fishing gear are made up of mostly synthetic materials, it will stay intact and continue to fish for a long time after ... -
The life-saving effect of biodegradable cotton thread in lost fishing traps: from a cleanup-project in Raet National Park, Norway
(Master thesis, 2022)The fishing gear used today is primarily made of synthetic materials, which gives the gear a long breakdown time. This means that Abandoned, Lost, and Discarded Fishing Gear (ALDFG) can continue fishing for a long time in ... -
Impacts of ghost fishing on European lobster (Homarus gammarus) and brown crab (Cancer pagurus) in Raet national park, Norway
(Master thesis, 2022)Lost fishing gear pose a threat to marine life in large parts of the world. Fishing gear have the potential to continue to fish for a long time after it has been lost, referred to as “ghost fishing”, an issue which has ... -
Benthic community distribution pattern in Sandnesfjorden
(Master thesis, 2021)In the marine environment, benthic macrofauna plays a crucial role in carbon and nutrient cycling, decomposition, and as prey items for higher-level consumers. The distribution and composition of macrofauna were studied ... -
Haul-out Behavior of Harbor Seals (Phoca vitulina) along the Norwegian Coast
(Master thesis, 2021)How do selected environmental factors affect haul-out behavior of harbor seals in Skagerrak and in northern Norway? Does the probability of hauling out differ between the geographical areas? -
Long term effects of activated carbon on benthic communities
(Master thesis, 2021)Thin-layer capping with activated carbon (AC) has a potential as situ remediation method for sediments exposed to hydrophobic organic compounds (HOCs). This treatment was applied at two test fields; one in the Eidangerfjord ... -
Homing Ability of Goldsinny Wrasse (Ctenolabrus rupestris)
(Master thesis, 2021)After the discovery of delousing abilities of temperate wrasses, several wrasse species are increasingly harvested in Norway and supplied to salmonid aquafarms to combat sea lice infestations. An increased ... -
