The abundance of sharks and rays can decline considerably with fishing, but assessing the drivers of community changes can be complicated by species interactions and variations in vulnerability to fishing. This study used data from five trawl surveys conducted between 1948 and 2005 to evaluate long-term trends in elasmobranch communities in the Adriatic Sea. Since 1948, catch rates have declined by > 94% and 11 species ceasing to be detected.
