Apuntes sobre la reproduccion de algunos Bagres marinos

Mouthbreeding in the male, and modifications of the pelvic fins of the female are recorded for the first time in Selenaspis herzbergii. The pelvic girdle of Selenaspis herzbergii is compared with those of Sciadeichthys proops, Arius spixii, and Bagre marinus. Data are given on eggs and fry in the buccal cavity of these four species of South American marine catfish, which were collected in Venezuela, in the Lagoon of Tacarigua, Gulf of Cariaco, and off Margarita Island.
