Feed and Feeding for Fish and Shellfish: Nutritional Physiology presents foundational knowledge and the most recent advances in aquaculture finfish and crustacean metabolism and nutritional requirements, feed ingredients, nutrient deficiency disorders, and integrated sciences. Nutrition is fundamental to the success and sustainability of the aquaculture industry as it relates to economics, fish health, high-quality product production, and pollution minimization. This book provides a unique, complete, and comprehensive coverage of the nutrition, metabolism, and feeding strategies of key aquaculture species. Written by an international group of experts, this work introduces nutrient requirements of finfish, prawn, shrimp, crabs, and lobster before delving into advances in feed ingredients, production, and practices. Latter chapters discuss the risks of nutritional deficiency and associated diseases and disorders. The final section of the book describes integrated sciences, including aquaculture species immune systems, muscle development, reproduction, gut health, and broader perspectives on seafood quality and food security.
