Sažetak
Previous work has identified maximum body size as an important functional life-history trait for marine fish species influencing their growth, natural mortality, recruitment, and resilience to exploitation. We use data from a large number of scientific bottom trawl surveys from West Greenland to the Adriatic Sea to compare the distribution of species richness and average number of individuals caught per hour of trawling across different fish communities. Although highly variable the data reveal several overall patterns. Going from north to south the total species richness and the total number of individuals caught per hour of trawling increase, while the average log maximum length of the individuals shows a consistent decrease. In contrast the average log maximum length of the species recorded remains stable throughout the area. The mesh size in the codend and the total number of hauls are significant covariates. We briefly discuss to what extent these patterns reflect differences in fish community structure with latitude or are generated by differences in levels of exploitation.
