Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science.

National Research Council (NRC): Nutrient requirements of fish and shrimp
The following information was supplied regarding data availability:. Atlantic salmon Salmo salar feeds have changed drastically in their composition from being predominantly marine-based to plant-based. This has altered the dietary supply and availability of micro-nutrients to Atlantic salmon. The impact of graded inclusion levels of a nutrient package NP comprising of 25 different micro-nutrients were studied in Atlantic salmon parr in freshwater Trial 1 and post-smolts in seawater Trial 2. Micro-nutrients, namely Zn, Mn, Se, Cu, Fe, Co, I and vitamin D3 were included in the NP with the objective of re evaluating the dietary need to meet the requirement of Atlantic salmon parr and post-smolt, when fed low fish meal, plant ingredient-based diets. Responses in apparent availability coefficient AAC , whole body and vertebrae mineral concentrations, and retention were analysed.
Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the edition.
Metrics details. A study of three feeding trials was conducted to investigate the dietary protein requirements of Pacific white shrimp Litopenaeus vannamei at three different growth stages. The three feeding trials were conducted in different-sized shrimp at 0. In trial 1, the growth performance was not affected by the dietary protein levels. However, protein efficiency ratio was significantly higher in P30 diet compared to P40, P45, and P50 diets. In trial 2, growth rate was significantly higher in P35 diet than in P25 diet.

Download PDF. Recommend Documents. Aquacult Int — DOI This new book, which updates and expands upon information given in the edition, has been put together by a committee of ten well-known aquatic animal nutritionists. Given the length of time that has elapsed since publication of the previous edition, this book is long overdue. The book summarizes current knowledge about nutritional requirements of fish and shrimp some readers will be more familiar with several species under the name prawns, and some information is also given for other crustaceans.
However, aquatic feeds generally require higher dietary concentration of crude protein CP vs. Many protein ingredients can be used to manufacture aquatic feeds, but fishmeal traditionally was the protein source of choice, because of its nutrient value, particularly its high levels of digestible CP and the balanced essential amino acid EAA profile. But global fishmeal supplies have leveled off as global aquaculture has grown rapidly, so fishmeal has become less available and more expensive to use as a main protein component in aquatic feeds. As a result, there has been a need to increase the dietary use of alternative protein sources, and available options include byproducts from agriculture, fisheries or the processing of terrestrial production animals. Some of these ingredients can contain CP levels comparable to fishmeal, but values usually range from 40 to 75 percent.
