Broodstock nutrition has been shown to influence the performance of eggs and larvae in marine finfish. The present study aimed to test the hypothesis that a broodstock conditioning diet with increased astaxanthin, taurine and water would have an effect on the early life stages in Atlantic cod. Thus, cod broodstock were fed two diets, a standard broodstock conditioning diet, and an experimental ...

Inspired by Ostrom’s Governing the Commons (1990), this thesis examines fisheries collective action in the Dutch brown shrimp fishery. The study was conducted as a qualitative case study, with semi-structured interviews and an analysis of literature and secondary sources as the main research methods. Taking the perspective of the appropriators, the main collective action problem turned out to be ...

Property rights and economic performance have been highly linked concepts, where the former influence the latter. In this thesis, we seek to explore property rights as fishing rights in two large fishing nations, Norway and Iceland, and the economic performance of the fishing sectors. However, there is a fundamental difference between the fishing sector in Iceland and Norway. In Iceland, the government ...

This thesis is dedicated to the case of the pink salmon (Oncorhynchus gorbuscha) in Norway. The pink salmon has a large native range and is indigenous to regions of the Pacific Ocean. It was deliberately introduced into rivers that drained into the White Sea by the Soviet Union. This was done through several attempts reaching from 1957 to 2001. These attempts resulted in secondary expansion to the ...

Nepal is a poor country where the problems of poverty and food insecurity is very much evident. Aquaculture has been identified as one of the major sectors that could bring about the changes in the lives of poor communities through employment, food security and income. Currently, the Government of Nepal has identified and recognized the contribution of aquaculture towards poverty alleviation and ...

Alaskan wild salmon and Norwegian farmed salmon represent the largest share of their respective global harvests of salmon by volume, yet both are exporting the majority of their harvests and byproducts for processing and are thereby missing out the potential to create local circular production systems for more environmentally sustainable processing . Alaskan salmon and Norwegian aquaculture have an ...

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 ...

The growing Atlantic salmon (Salmo salar) aquaculture production is confronted with many challenges that limit the potential development of the industry. The major current problem threatening the salmon aquaculture production is the parasitic sea lice (Lepeophtheirus salmonis) that negatively affects both cultured salmon and wild stock populations. Several treatment options have failed to deliver ...

The Norwegian aquaculture industry is today experiencing increasing demands of Atlantic salmon (Salmo salar L.) from global markets. However, past years has not seen the same rise in production as in value. In a time where several area and environmental-related challenges are hindering further growth of the Norwegian aquaculture industry, the development licenses have become the latest licensing ...
