Nutritional Requirements of Prawn—VII Effect of Dietary Lipids on Growth

Abstract

The effects of dietary lipids on the growth and fatty acid composition of the prawn, Penaeus japonicus, were examined. The survival and growth of prawn kept on soybean oil diet were extremely low. However, all diets containing pollack residual oil were found to improve both survival and growth. The highest growth was obtained in the prawn group receiving 8% short necked clam lipid. Dietary lipids affected the fatty acid composition of prawn lipids. The diets containing either pollack residual oil or short necked clam lipid elevated 20: 5ω3 and 22: 6ω3 levels as compared with soybean oil diet. © 1977, The Japanese Society of Fisheries Science.
