An overview of the nutrition, feed and feeding techniques of prawn penaeid/shrimps
MetadataShow full item record
This paper echoes what transpired during the first International Conference of Penaeid Prawns/Shrimps held in Iloilo City in December 4-7, 1984, particularly on the Nutrition nd Feed Development. Around 25 papers were presented during the conference. The nutrient requirements of P. japonicus and to some extent, P. monodon have been studied quite extensively compared to other penaeid species. Requirements for protein, carbohydrates fats, amino acids and essential fatty acids for juveniles and larvae have been defined compared to those of the broodstock. Optimum protein levels for prawn juveniles vary from 28-38% for P. kerathurus, 40-46% for P. monodon, 43% for P. indicus and 50-54% for P. japonicus. Dissacharides like sucrose and trehalose have been found to be good source of carbohydrates at 20-25% in the diet. Crustacean diets require around 0.5% cholesterol. There are few studies on vitamine and mineral requirements. There are artificial diets for juveniles and microencapsulated diets that can completely replace live organisms as larval feed. Microencapsulated diets have been field-tested for P. vannamei, P. stylirostris, P. monodon, P. indicus and P. merguiensis in Ecuador, Taiwan, Malaysia, Thailand and the Philippines. When a commercial diet for the broodstock becomes available ther will be an artificial diet for athe life cycle of tha prawn.

Leucaena leucocephala leaves in formulated feed for Penaeus monodon: a concrete example of the application of histology in nutrition research Vogt, Günter; Quinitio, Emilia T.; Pascual, Felicitas P. (Elsevier, 1986)Penaeus monodon postlarvae were fed with formulated diets containing either soaked or unsoaked Leucaena leaves. A similarly prepared feed with soybean in place of Leucaena was used for comparison. Results were analysed by ...
