Nutrition requirements for giant freshwater prawn, Macrobrachium rosenbergii (De Man, 1879) broodstock: A review

Abstract

The giant freshwater prawn (GFP), Macrobrachium rosenbergii (De Man, 1879) farming industry consistently maintains a high production volume, ranging from 233 to 238 thousand metric tons worldwide annually from 2014 to 2018. Improvements in the quality and quantity of fry are necessary to further boost production. Maturation feed stands as a critical factor in enhancing the quality of broodstock. The nutrient requirements for GFP, (M. rosenbergii) broodstock consist of essential nutrients such as protein (40-45%), lipids (8-10%), and carbohydrates (25-35%). In addition to these major nutrients, minor nutrients like essential fatty acids, cholesterol, phospholipids, vitamins, and minerals play a crucial role in developing a high-quality maturation feed. Research focused on determining optimal levels of essential amino acids and essential fatty acids is essential to enhancing reproductive performance. High-quality maturation diet significantly contributes to the broodstock's reproductive performance and high-quality fry, both of which are paramount in the GFP farming industry. This review paper on maturation diets for GFP serves as a valuable reference for hatchery managers, aiding in the production of high-quality maturation feeds to enhance production efficiency.
