Abstract

Tambaqui (75%) was reared in polyculture with common carp (25%) from 5.5g and 3.4g mean weight respectively for a period of 505 days. Ponds of 40m2 were stocked at a total density of 10000 ha-1, and daily manured with 150 kg.ha-¹, of swine fresh manure. Fish were supplemented fed with corn or pearl millet grain, offered in submersed trays at a daily rate calculated as 3% of total biomass. The experiment polyculture had a mean net yield of 6.6; 5.2 and 2.1 t.ha-¹.year-¹ of pearl millet, corn and manure respectively. The result of this study indicates that rearing tambaqui in semi-intensive polyculture without supplementary feed had a low growth and the pearl millet fed fish showed a high performance.

KEY-WORDS: Fishes; polyculture; pearl millet.
