Aquaculture, the youngest, fastest-growing, and most dynamic protein-producing industry, has the key advantage of efficient use of feed that allows farmed fish to be competitively priced compared with terrestrial proteins. Sustainable Aquafeeds: Technological Innovation and Novel Ingredients explores the present and future evolution of feeds, explains the current challenges for aquaculture, and considers how advances in technologies and ingredients can produce aquafoods for the increasing world population. International contributors to this book provide state-of-the-art information on the profile of the aquafeed industry, including factors affecting supplies and prices of key ingredients for aquafeed production. An entire set of chapters covers the scientific advances and feed industry initiatives in accordance with modern consumer trends, updating readers on the most promising strategies. These include the use of novel ingredients for nutrient supplementation and the enhancement of their use by genetic selection. The authors hope to inspire a collaboration of NGOs, researchers, and private partnerships to replace wild-caught ingredients by accelerating and supporting the scaling of innovative, alternative, aquaculture feed ingredients, including bacterial meals, plant-based proteins, algae, and yeast.

Probiotic has been used for centuries especially in fermented dairy products since Metchnikoff associated the intake of fermented milk with prolonged life. Probiotics confer many health benefits to humans, animals, and plants when administered in proper amounts. These benefits include the prevention of gastrointestinal infections and antibiotic-associated diarrhea, the reduction of serum cholesterol and allergenic and atopic complaints, and the protection of the immune system. Furthermore, the proper usage of probiotics could suppress Helicobacter pylori infection and Crohn's disease, improve inflammatory bowel disease, and prevent cancer. In this book, we present specialists with experience in the field of probiotics exploring their current knowledge and their future prospects.

As sequel to Aquatic Animal Nutrition – A Mechanistic Perspective from Individuals to Generations, the present treatise on organic macro- and micronutrients continues the unique cross fertilization of aquatic ecology/ecophysiology and aquaculture. This treatise considers proteins and their constituents, carbohydrates from mono- to polysaccharides, fatty acids from free acids to fat, and waxes. It becomes obvious that these organic nutrients are more than only simple fuel for the metabolism of animals; rather, their constituents have messenger and controlling function for the actual consuming individual and even for succeeding generations. This aspect will become particularly clear by putting the organisms under consideration back into their ecosystem with their interrelationships and interdependencies. Furthermore, micronutrients, such as vitamins and nucleotides as well as exogenous enzymes, are in the focus of this volume with known and still-to-be-discovered controlling physiological and biomolecular functions. Aquatic Animal Nutrition – Organic Macro and Micro Nutrients addresses several gaps in nutritional research and practice. One major gap is the lack of common research standards and protocols for nutritional studies so that virtually incomparable approaches have to be compared. This applies also to the studied animals, since most approaches disregard intraspecific variabilities and the existence of epimutations in farmed individuals. Furthermore, recalling the Mechanistic Perspective from Individuals to Generations, dietary benefits and deficiencies have effects on succeeding generations. In most studies, this long-term and sustainable aspect is overruled by pure short-term production aspects. By comparing nutritional behavior and success of fishes and invertebrates, Aquatic Animal Nutrition points out different metabolic pathways in these animal groups and discusses how, for instance, fishes would benefit when having some successful metabolic pathway of invertebrates. Application of novel genetic techniques will help turn this vision into reality. However, a widely missing link in the current nutritional research is epigenetics regarding transgenerational heritages of acquired morphological and physiological properties. To increase public acceptance, nutritional optimization of farmed animals based on this mechanism, rather than genetical engineering, appears promising.

Manipulation of the microbial gut content of farmed fishes and crustaceans can have a marked effect on their general health, growth, and quality. Expertly covering the science behind the use of prebiotics and probiotics this landmark book explains how the correct manipulation of the gut flora of farmed fishes and crustaceans can have a positive effect on their health, growth rates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probiotics and Prebiotics provides a comprehensive overview of the current knowledge of the gut microbiomes of fish and their importance with respect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world’s leading authorities and edited by Dr Daniel Merrifield and Professor Einar Ringø, this important book discusses in detail the common mechanisms for modulating microbiomes, particularly at the gut level (e.g. probiotics, prebiotics and synbiotics). The book is a key resource for an understanding of the historical development of these products, their known mechanisms of action and their degree of efficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself, and more broad aspects of microbe-live feed interactions, provide essential reading for researchers, academics and students in the areas of aquaculture nutrition, fish veterinary science, microbiology, aquaculture, fish biology and fisheries. Those involved in the development and formulation of aquaculture feeds and those with broader roles within the aquaculture industry will find a huge wealth of commercially-important information within the book’s covers. All libraries in universities and research establishments where biological sciences, nutrition and aquaculture are studied and taught, should have copies of this excellent book on their shelves.

This book has been developed to provide a detailed discussion of probiotics, which have been evaluated for use predominantly in fish and shellfish aquaculture. This book highlights strengths and weaknesses in knowledge and discusses gaps that need to be addressed. There has been a great deal of research concerning the use of probiotics in aquaculture. To date, a wide range of Gram-positive and Gram-negative bacteria and some eukaryotes, i.e. yeasts and unicellular algae, has been reported to be beneficial to aquatic hosts. Following oral uptake, benefit includes improved growth performance and protection against many bacteria and some parasitic diseases. This book will be suitable for scientists, veterinarians, professionals, and senior students involved in aquaculture.
