Viabilidade econômica do uso de aerador para o cultivo semi-intensivo de Tambaqui em tanques escavados

Abstract: The increase in the market for fish motivated the fish industry to intensify its demand, inserting sophisticated equipment in the production systems. But little is known about the real cost of tambaquis producing with the use of these technologies. Therefore, were evaluated the economic viability of semi-intensive cultivation of tambaqui in two tanks, T1 (without aerator) and T2 (with aerator), in each tanks was inserted 275 fish (≈ 40 g), that were monitored weekly during a year, for biometric collections (weight and furcal length), realized concomitant with limnological samplings. The data shows that only dissolved oxygen (≈7.79 and ≈8.30) and total ammonia (≈0.27 and ≈0.16) differed between the tanks, respectively. In the economic analysis, the Operational Cost of Production (OCP) was used, which for the T1 was R$ 1,803.35 (dry fishmeal), while in T2 it was R$ 3,552.94 (dry fishmeal + electricity). The zootechnical variables of the tambaquis groups did not differ significantly
