The grass carp (Ctenopharyngodon idella) was first introduced in 1970s from Japan at the Chascomús and El Burro lakes in Buenos Aires province to control the growth of dense of aquatic plants in waterways and lentic water bodies. It is obvious the released grass carp were able to adapt and spread out.
Grass carp has been utilized in aquaculture by small-scale rural producers whether in monoculture or in polyculture along with other carps and/or “pacu”. The type of aquaculture is mainly practiced at the Misiones province (NEA). According to fishery statistics, about 3000 tons of grass carp were produced in 2003. The photo shows a field display of produced grass carp.
