The Effect of Climate Change on the Productivity and Profitability of Cod in the Barents Sea
Climate change has an inevitable natural impact on fisheries. Continually, several models made of both biological and economic factors are used to measure the effects of climate change on fish stocks. This study has as its objective to identify how climate change effect through carrying capacity aff...

Climate change has an inevitable natural impact on fisheries. Continually, several models made of both biological and economic factors are used to measure the effects of climate change on fish stocks. This study has as its objective to identify how climate change effect through carrying capacity affects the productivity and profitability of the cod stock in the Barents Sea. Two scenarios one with climate change effect and the other without climate change effect are compared to explore the climate change effect. This thesis uses a simple bioeconomic model based on a surplus production model to conduct the analysis over 50 years.
