Abstract
In order to evaluate the zootechnical parameters for red-tailed tarpon Brycon cephalus fingerlings, in a region other than Amazonia, the evaluation of growth parameters in temperate waters was carried out for 60 days in the port of Ilo, Department of Moquegua. 84 fingerlings were used in 70 liters of water and two biometrics were performed, fluctuating in size from 3.5 cm to 9 cm at the end of the trial. Fingerlings were fed commercial trout feed of 45% protein, 8% fat and 25% carbohydrate, a feeding rate of 4.5% of biomass, distributed 3 times per day. The results reported as an average water temperature of 20.6°C, survival rate of 2.4%, growth determined by y=0.0155 X 2.8284 and a coefficient of determination of R²=0.975, average condition factor (K): 0.04393±0.0126 SD, Relative Growth Rate (TCR) of 9.5%, Specific Growth Rate (TCE) of 3.9% and Apparent Feed Conversion (CAA) of 1.4. With which it is observed that the parameters evaluated in the coastal zone of southern Peru are close to the native cultivation conditions.
