Towards a culture technology for pescado bIanco, Chirostoma estor estor

摘要

In 1999 we established a major project to investigate the potential for culturing the endangered Pescado Blanco, C. estor estor, of Lake Patzcuaro in the Mexican Altiplano. This is a major species in the relict flock of Atherinopsid fishes unique in central Mexican lakes. The Atherinopsidae are a large group, also known as silversides, which includes the well-known Pejerrey (Odontesthes bonariensis) of South America and the brackish water Menidia group. The Altiplano lakes of Mexico are remnants of a vast inland sea, once connected to both the Pacific and Atlantic oceans and it is considered that the Chirostoma species flock became isolated from their traditional migratory routes relatively recently in evolutionary terms.
