How Can Innovative Post Smolt Strategies Revolutionize Sustainability in Salmon Farming?

Abstract

This thesis evaluates the effectiveness of Closed Containment Systems (CCS) and Recirculating Aquaculture Systems (RAS) in enhancing the sustainability and economic possibilities of the Norwegian salmon industry in the Western Norway region. Utilizing data from Ovum AS for the post smolt stage and advanced simulation modelling, the study demonstrates that employing larger post smolt sizes to the open net farming practice can dramatically reduce mortality rates by up to 40% and decrease the frequency of sea lice treatments by over 80%.

These improvements significantly support fish welfare and reduce the environmental footprint of aquaculture practices. Furthermore, the adoption of CCS and RAS not only optimizes operational efficiencies but also elevates profitability by enhancing operational margins through better maximum allowed biomass utilization and reduced operational risks. The findings advocate for a strategic shift in practices involved in farming Atlantic salmon, suggesting that the integration of cutting-edge technologies in post smolt strategies is imperative for achieving sustainable growth and resilience in the industry. This research provides compelling evidence that advanced aquaculture systems are essential for the future sustainability and economic success of salmon farming in Norway.
