Abstract

This experiment was carried to evaluate the hydrological alterations in the production of Nile tilapia (Oreochromis niloticus) in raceway, with different rates of water exchanges, to estimate the impact of this system on water quality. Four treatments with total exchange of water at 30, 90, 120 and 150 minutes were analyzed. A total of 1,500 fingerlings were used. They were reverted for male, fed three times a day with commercial extruded ration 36% and 32% of crude protein. The following hydrological parameters were evaluated: dissolved oxygen, temperature, alkalinity, pH, solids in suspension, turbidity, electrical conductivity, phosphorus, nitrite and nitrate. All tested treatments maintained the hydrological variables within patterns suggested for fish raising, rationalizing the use of water for cultivation.

KEYWORDS: High water flow, Oreochromis niloticus, water quality, water total exchange.
