Disputas og prøveforelesning - Enis Kostak

Trial lecture on assigned topic will take place at 10.15:

"The role of new technologies to enhance our understanding of fish behavior to improve trawl fishing operations"

Later, at 12.15 he will defend his thesis entitled:"Catch and energy efficiency in trawls targeting mesopelagic fish, Calanus and northern krill"

Acting Dean Roy Dalmo will lead the disputation.

Popular Science Summary
This PhD explored how to design more efficient trawls to harvest small, nutrient-rich marine species such as mesopelagic fish, Calanus finmarchicus, and northern krill, potential new resources for aquaculture and food production. Because these species are diminutive and live deep in the ocean, specialized trawls with fine meshes are needed, which often create high drag and energy costs. Through a mix of sea trials, flume tank experiments, and AI-based analysis, the research identified gear design parameters to improve catch efficiency while reducing energy use in future commercial fisheries for those species. The results support future sustainable harvesting of these underused marine species.
