Inland Fisheries

1.4.8 Catch trends by major inland water species groups

The following figure shows catch trends since 1970 by major species groups caught in inland fisheries. In 2005, cyprinids returned as the dominant group after being exceeded for some years by the tilapias group (and in 2002 also by freshwater crustaceans). Catches of freshwater molluscs have decreased significantly since 2002, and this may be due to their extreme vulnerability to habitat degradation, overexploitation, and predation by alien species. It is noteworthy that catch trends for inland water species groups present several more abrupt ups and downs than those of marine species groups.
