In deep water: Long-term trends in demersal fish diversity in Skagerrak and the Norwegian trench

Throughout history, human activities have had profound impacts on marine ecosystems, with clear evidence of these consequences observable in the Skagerrak region. Oceans have historically been a critical resource for humankind, supplying food for the world's population. However, unsustainable practices such as overfishing and the emission of CO2, which leads to increased sea temperatures, have jeopardized this valuable resource. The current study investigates changes in biodiversity and population size of various fish species in deep water areas of Skagerrak. The data is obtained from the Norwegian Bottom Trawl Survey for Northern Shrimp (Pandalus borealis) in Skagerrak and the Norwegian De…
