Salmo carpio
''Salmo carpio'', also known as the carpione (''carpione del Garda''〔Crivelli, A.J. 2006. (''Salmo carpio'' ) In: IUCN Red List of Threatened Species. Version 2010.1. Downloaded on 2 April 2010〕 or ''Lake Garda carpione''〔S. Melotto, G. Alessio (2006) (Biology of carpione, ''Salmo carpio'' L., an endemic species of Lake Garda (Italy) ) ''Journal of Fish Biology'' 37, 687-698.〕) is a salmonid fish endemic to Lake Garda in Italy. It has been introduced to a number of other lakes in Italy and elsewhere but unsuccessfully in all cases.〔 The population in Lake Garda has been strongly declining, and is considered critically endangered.〔〔
The main threats are due to overfishing, pollution and possibly competition from introduced species such as Coregonus and Salmonidae.〔(Fishing World Records - Salmo carpio Carpione )〕
