Aquafeed Formulation is the only resource that provides summaries with examples and formulation techniques specifically to meet the needs of anyone in the aquaculture industry. As feed is the largest single cost item in aquaculture production, and formulating aquaculture feed requires many combinations of several ingredients and nutrient requirements, this book takes a clear-and -concise approach, providing essential information on formulation and covering relevant available software, feed nutrients, and additives such as enzymes and phytase and conjugated fatty acids, as well as best industry practices to improve aquafeed production. Users will find this to be a one-stop resource for anyone interested or involved in, the global aquaculture industry. - Includes the latest software evaluation for calculating protein and amino acid sources, trace minerals, and vitamins for aquaculture diets - Provides essential information on formulation, covering feed nutrients and additives such as enzymes and phytase and conjugated fatty acids - Presents factors affecting nutrient recommendations for aquaculture diets and nutritional effects on aquaculture nutrient excretion and water quality - Covers a broad range of techniques to understand the nutrient recommendations in the NRC guide

Aquaculture has become one of the main sources of human food, and the per capita food fish supply has reached 21 kilograms in 2019. With the expansion of the farming industry and the deterioration of the farming environment, outbreaks of various infectious diseases have become more and more serious, resulting in huge economic losses. In the past, antibiotics were commonly used to control diseases in aquaculture animals. However, the overuse of antibiotics caused various problems such as pathogen resistance, drug residues and environmental pollution. As a result, the development of functional ingredients added to feed to improve the health of aquaculture animals is necessary for the sustainable development of the aquaculture industry.

This Special Issue presents high-quality research papers as well as review articles addressing recent advances in the use of marine bioactives in animal nutrition. The marine environment constitutes a relatively untapped source of biologically active compounds that can be applied in various areas, such as improvement of animal performance, health maintenance, and disease prevention. Numerous marine-based compounds isolated from marine organisms (especially seaweeds) have diverse biological activities, including antioxidative, anti-inflammatory, antibacterial, antifungal, and antiviral activities that can be beneficial to animal health. Additionally, the application of marine bioactives as feed additives can increase the nutritional value of products of animal origin. In this Special Issue, the main attention was focused on seaweeds and their application in poultry (laying hen and broiler chickens) and pig feed. The suitable processing of marine resources required for their optimal use as feed/feed additives was underlined. The contained publications present scientific evidence for the use of various seaweeds as feed additives that improve health (enhanced immunity, prebiotic effect), growth performance, and production. Inclusion of this unconventional material in animal nutrition can enrich products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids, and pigments which are beneficial for consumers.

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

Sea cucumbers belong to the Phylum Echinodermata. There are more than 900 recorded species of sea cucumber of which more than 40 are edible. As a food source, sea cucumbers are rich in protein, low in fat, rich in collagen, sulfated polysaccharides, phospholipids, glycolipids, saponins and other functional components. Therefore, sea cucumbers have important nutritional and medicinal value. Growing awareness of these health benefits has promoted growth in marine aquaculture and processing technologies for the development of sea cucumber products for many applications.Novel perspectives of nutritional functions and processing technologies of sea cucumbers are defined in this book. The chemical structure and nutritional function of sea cucumbers are systematically reviewed. These include the functional/nutritional components, the endogenous enzymatic properties related to processing efficiency and product quality, and the efficient preparation technology of functional components. The traditional processing technology is presented as the background context to highlight the advances in new processing technologies including low-temperature cooking technology based on controllable negative pressure system, heat pump-hot-blast air combined drying technology, microwave sterilization of instant sea cucumber, collagen stabilization technology. The book finishes with the authentication of sea cucumber types and origin, quality standards, product quality control systems and food safety requirements.
