Resumen:
Paleogeographical, morphological, ecological, physiological, linguistic, archeological and historical evidence demonstrated that the wild ancestor of the common carp Cyprinus carpio Linnaeus, 1758 originated in the Black, Caspian and Aral sea drainages and naturally dispersed east into Siberia and China and west as far as the Danube River. This species has been introduced in all continents. In most countries where it was introduced, a wide array of negative impacts on native biota and ecosystems has been documented. Because of its historical use in aquaculture and as an ornamental fish, this species has become widely dispersed. It is recorded in more than 50 localities in Argentina: in the Paran a, Uruguay and Plata river basins, as well as in the Mirim lagoon (Rio Grande do Sul, Brazil). In the Pampa plain the distribution of this species is restricted to freshwater ecosystems of the Salado River Basin. In the present paper three specimens of the exotic common carp C. carpio were recorded for the first time in the inner zone of Mar Chiquita coastal lagoon (37, 35, 25, S; 57, 22, 21 W) (Fig. 1a,b) on 20 January 2014. Specimens were collected during summer samplings in lotic channelized tributaries of the lagoon. Body colouration, standard counts and measurements fit previous descriptions of the species. Two specimens were adults: one male in the maturing reproductive phase, and one female in advanced maturation. The presence of C. carpio is of great concern since it might represent the beginning of the second large invasion process in this coastal-estuarine ecosystem.
