This Fisheries and Aquaculture Technical Paper presents the findings of a value chain analysis of the aquafeed (aquatic animal feed) sub-sector for the striped catfish (Pangasianodon hypophthalmus) farming in Viet Nam, including a review of aquafeed regulatory framework in the country. The striped catfish (pangasius) production sub-sector is characterized by intensive pond production technology and high-quality production inputs. In 2014, annual production of pangasius was 1 143 797 tonnes. The key actors in the value chain comprise input suppliers, including feed ingredients suppliers, feed manufacturers, and hatchery operators (seed producers), along with fingerling and grow-out farmers, fish processors, exporters, consumers and service providers. In recent years, large-scale vertically integrated enterprises have started to emerge that operate along the entire value chain, and these now dominate many areas of production.

Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements. - Features expansive updates to the previous edition, including a new chapter dedicated to diet analysis and evaluation - Addresses the roles of fish nutrition and feeds on sustainability and the environmental impacts of aquaculture - Covers basic nutritional biochemistry and applied nutritional topics
