|Issue Date:||2019||Journal:||Journal of Fish Biology||Abstract:||In this study, we used a historical collection of photographs taken by recreational fishers from 1940 to 2014, at the island of Gran Canaria, to show both a significant decrease in the mean total length of Epinephelus marginatus and a concurrent change in the composition of captures. Before 1980, the mean total length of fish caught and photographed was c. 100 cm, while after 2009 this was typically < 40 cm. Before 1980, the predominant captured species was E. marginatus (an apex predator), but currently the majority of catches are of omnivorous species, in particular the parrotfish, Sparisoma cretense and seabreams Diplodus spp. Overall, integration of these results indicates a qualitative and quantitative variation in captures of recreational fishers, probably as a sign of change in ecological balances and the overfished status of many target species.||URI:||http://hdl.handle.net/10553/58415||ISSN:||0022-1112||DOI:||10.1111/jfb.13969||Source:||Journal Of Fish Biology [ISSN 0022-1112], v. 94 (6), p. 857-864|
