Pelletized diets containing different amounts of sun‐dried shrimp meal and brewer's yeast were tested. A relationship was observed between the content of shrimp meal and brewer's yeast in the diets and increased growth of juvenile shrimp, Penaeus stylirostris. Data suggested that in feeds containing 5% squid meal, up to half the shrimp meal can be replaced by brewer's yeast. These feeds should thus contain at least 15% shrimp meal and less than 15% brewer's yeast. A quadratic correlation was found between the rate of growth of juvenile shrimp and the percentage of linoleic acid in the diets. The best nutritional response should be obtained in rations containing 14.5% linoleic acid. The same type of relation was observed for the ratio of the linolenic series (ω3)/linoleic acid (106) with the ratio of 1.18 giving the best nutritional response for the diets tested in this study.
