An overview of the nutrition, feed and feeding techniques of prawn penaeid/shrimps
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.

Piedad-Pascual, Felicitas. (Asian Fisheries Society. AFS Spec. Publ. 4, 1989)World demand for shrimp has increased significantly in the last decade. Of the 32 species investigated, the most commonly cultured in Southeast Asia is the Penaeus monodon . Formulated feed constituted around 50% of the ...
Piedad-Pascual, Felicitas (Philippine Council for Aquatic and Marine Research and Development, 1989)Knowledge on nutritional requirements of prawn juveniles and broodstock are scanty. However, relatively more information is now available with regard to requirements of juveniles compared to that of broodstock. Many ...
Pascual, Felicitas P. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1989)Following an account of the feeding habits and nutritional needs of Penaeus monodon, diet formulation for cultured shrimp is discussed in detail. Equipment required, preparation of the diets and methods of feeding are detailed.
