New records of invasive mollusks Corbicula fluminea (Muller, 1774), Melanoides tuberculata (Muller, 1774) and Tarebia granifera (Lamarck, 1816) in the Vicente Guerrero reservoir, Mexico

The Vicente Guerrero reservoir is the sixth largest water reservoir in Mexico. This is a primary water source for the northeast region as well as a frequently holiday touristic site. In this paper we report aquatic specimens of the bivalve Corbicula fluminea, along with the gastropods Melanoides tuberculata and Tarebia granifera for the first time in the reservoir. This is also the first report of M. tuberculata and T. granifera for the Soto la Marina basin, and the first record of T. granifera for Northeast Mexico. The establishment of these species in the water body represents a potential threat to the native species and human health, since they are intermediate hosts in the life cycle of some parasites, such as Centrocestus formosanus trematode. Their arrival may be due to aerial, aquatic or commercial dispersion, since they can become adhered to, and hidden easily on birds, boats or aquarium ornamental plants, respectively. The introduction of these species may also cause potential economic losses for the agricultural. aquaculture and fishing activities in the local area. Due to high potential of dispersion, displacement of native species and pathogen transmission, the establishment of preventive actions is recommended to avoid their potential expansion in other aquatic bodies of the Soto la Marina basin.
