Leucism in <em>Astroblepus ubidiai<em> (Pellegrin 1931) (Siluriformes: Astroblepidae), in Imbabura Province, Ecuador

Abstract

The leucism is an aberration in pigmentation, resulting from a genetic abnormality and occurs in all vertebrate groups in which the fish are included. In Ecuador it has not reported such anomalies in fish. Is presented for the first time a case of partial leucism in an individual of Andean Catfish (Astroblepidae), observed in a spring located near the Lake San Pablo Canton Otavalo, Imbabura Province, Ecuador.
