Abstract: To assess the effect of protein levels in diet on growth of pink shrimp juveniles (Farfantepenaeus notialis), two completely randomly experimental designs were carried out, one at laboratory scale during 8 weeks and the second one in fertilized earthen ponds during 20 weeks. Samples of pink shrimps obtained after spawning in the laboratory, were used. Isocaloric practical diets containing 35, 40 and 45% were used in the first experiment and 40 and 45% protein in the second one. In both trials, shrimps fed with 45% protein diet reached the highest growths. The nutritional factors assessed were always better in that organisms fed with the diet of higher protein content. The histological analysis of the hepatopancreas in shrimp feds with diets containing lower protein levels showed degeneration and necrosis of the hepatopancreatic tubes. Protein level in diets affected the digestive enzymes activity and its behaviour was similar in both experiments. The best general proteolitic and like trypsin activities, were observed in shrimps that reached the highest growths.
