. Larvae of Rana perezi Seoane were reared under laboratory conditions on three compounded diets, three fresh diets and three mixed diets in an attempt to compare the nutritive use and the relative performance of the feeds. The indices of nutritive use help to evaluate the diets. Best digestibility was observed with the fresh diets, although the animals grew slowly. A diet rich in protein (40%), fats, and carbohydrates improved growth rates.
