The present study describes the fatty acid composition of brown shrimp ( Penaeus aztecus ) at two different growth stages, juvenile and spawned female. It was noted that P . aztecus contained large amounts of higher fatty acids typical of marine animals. Linolenic acid was present in greater quantities in juveniles than in adults. This information was used to perform growth trials to determine the growth rate of brown shrimp fed diets containing varying amounts of linolenic acid. Studies showed that increasing linolenic acid to the 1% level improved growth in juveniles by about 14% over growth achieved using diets without additive linolenic acid.
