Resumen

The protein requirement for gamitana in the fry stage, was determined through the zootechnical parameters of liweweight gain and food conversion. There were used 128 gamitana fingerling of 3.19 g on average liweweight with increasing levels of protein (30%, 32%, 34% and 36%). Diets were isoenergetics (3.6 Mcal/kg DE), were fed for six weeks. The protein requirement was determined by the quadratic polynomial regression method. The results were: the protein requirement for the gamitana fingerling with the daily weight gain variable was 32.61%, and with the food conversion variable it was 33.83%.
