Can small-scale northern marine protected areas work as management tools for a mobile temperate fish species? A before-after control-impact study of coastal Atlantic cod (Gadus morhua)
(Master thesis, 2016)The recruitment and spawning stock biomass of Atlantic cod (Gadus morhua) along the Skagerrak coast have been extremely low the last years and overfishing seems to be one of the main factors for this decrease. Marine ... -
Effects of nutrients and temperature on mobilization of mercury from sediment of the industrial contaminated Gunneklevfjorden, southern Norway
(Master thesis, 2016-10-28)Mobilization of mercury (Hg) and Hg methylation rates in sediment and water from the contaminated fjord Gunneklevfjorden, Telemark, Norway, were investigated in a laboratory experiment with addition of nutrients (as glucose ... -
Metal concentrations in blue mussel (Mytilus edulis) in the Kaldvellfjord, Lillesand county, affected by metal rich runoff.
(Master thesis, 2016)In this master thesis there has been studied possible effects from acidic, metalrich runoff on blue mussels (Mytilus edulis) in the Kaldvellfjord (Lillesand county), as a result of sulphide oxidation from deposits in the ... -
Relationship between modelled drift of eggs and larvae and the geographical variation in recruitment of cod (Gadus morhua) and pollack (Pollachius pollachius) in Tvedestrandsfjorden
(Master thesis, 2016-01-18)Oceanographic current models are frequently used to predict particle drift in marine ecosystems. In our study, eggs and larvae of cod (Gadus morhua) and pollack (Pollachius pollachius) are used as particles in the model ...
