Diet changes observed in demersal fish species such as whiting reflect impacts from altered benthic prey communities.
The study finds that sandeels have become a dominant dietary component in later decades compared to the 1900s.
Using historical data spanning over a century, the analysis highlights long-term dietary shifts among fish species.
Findings emphasize the importance of addressing trawling and eutrophication in marine policy frameworks.
