Primer registro del caracol manzano exótico Pomacea canaliculata (Gastropoda: Ampullariidae) en México, con comentarios sobre su propagación en el bajo río Colorado

摘要

The apple snail Pomacea canaliculata (Lamarck, 1822) is for the first time reported for Mexico. The species was discovered in several locations adjacent to the Matamoros-1950 dam, All-Mexican Canal, Algodones, Baja California. The spread of P. canaliculata in Mexican waters was through the tributaries of the Colorado River from a population originally introduced in Yuma, Arizona around 2005. To date, no harmful effects have been detected on native vegetation or fauna of the Colorado River or agricultural crops in the Mexicali Valley, Baja California.
