Abstract
This paper describes standard procedures developed to induced spawning of the spadefish Chaetodipterus faber (Broussonet) (Pisces: Ephippidae) and rear their larvae under controlled conditions. The spadefish are induced to spawn using human chorionic gonadotropin and luteinizing-releasing hormone analog. Larval rearing is done in the same tank in which the eggs hatched. Larvae were fed with mixed live food and normally after 31 days attained a total length between 24 and 33 mm. In twenty four trials realizated the whirling disease and vibriosis were common. During 1991-1992 a total of 26,731 juveniles were harvested.
