Aquatic Nutrition And Intestine Immunity

Mucosal Health in Aquaculture is an essential reference on mucosal health for the diverse aquaculture community. Rich in explanatory figures and schematics, the book includes important concepts such as structural and cellular composition of mucosal surfaces in fish and shellfish, known functional roles of molecular and cellular actors during pathogen invasion, impacts of nutrition on the mucosal barriers, impacts of chemical treatments on mucosal surfaces, mucosal vaccines and vaccination strategies, and more. The health of cultured aquaculture species is critical in establishing the sustainable growth of the aquaculture industry worldwide, and mucosal health is of particular interest to those working in aquaculture because mucosal surfaces (skin, gill, intestine, reproductive tissues) constitute the first line of defense against pathogen invasion. Mucosal Health in Aquaculture captures the latest research on mucosal barriers in aquaculture species and their impacts on nutrition and immunity to ensure sustainable aquaculture development. Includes research case studies to exhibit the importance of various integrated approaches to mucosal health Examines the latest scientific methods and technologies to maximize efficiencies for healthy fish production for farming Brings together the latest knowledge and research on mucosal barriers and mechanisms from world-wide experts in mucosal health Utilizes detailed diagrams and figures to enhance comprehension

Manipulation of the microbial gut content of farmed fishes andcrustaceans can have a marked effect on their general health,growth, and quality. Expertly covering the science behind the useof prebiotics and probiotics this landmark book explains how thecorrect manipulation of the gut flora of farmed fishes andcrustaceans can have a positive effect on their health, growthrates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probioticsand Prebiotics provides a comprehensive overview of the currentknowledge of the gut microbiomes of fish and their importance withrespect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world’s leading authorities andedited by Dr Daniel Merrifield and Professor Einar Ringø, thisimportant book discusses in detail the common mechanisms formodulating microbiomes, particularly at the gut level (e.g.probiotics, prebiotics and synbiotics). The book is a key resourcefor an understanding of the historical development of theseproducts, their known mechanisms of action and their degree ofefficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself,and more broad aspects of microbe-live feed interactions, provideessential reading for researchers, academics and students in theareas of aquaculture nutrition, fish veterinary science,microbiology, aquaculture, fish biology and fisheries. Thoseinvolved in the development and formulation of aquaculture feedsand those with broader roles within the aquaculture industry willfind a huge wealth of commercially-important information within thebook’s covers. All libraries in universities and researchestablishments where biological sciences, nutrition and aquacultureare studied and taught, should have copies of this excellent bookon their shelves.

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.
