Book excerpt: 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.

Barry and published by . This book was released on 2017 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aquaculture industry is expanding to supply the demand for sustainable protein, essential nutrients, and energy. Recent reports of worldwide fish production indicate a rise in aquaculture, coupled with near static capture fishery landings. Feed prices represent a major limiting factor for aquaculture as ingredients sourced from wild caught fisheries remains stagnant. Fish oil is included in the realm of expensive, marine sourced ingredients and is a highly nutritious commodity. Lipids are indispensable constituents of aquafeeds because they provide essential energy and nutrients. Some fatty acids are deemed essential because they must be obtained via dietary intake to avoid pathology and ultimately mortality. Depending upon the species, essential fatty acids may include C18 polyunsaturated fatty acids (C 18 PUFA) or long chain polyunsaturated fatty acids (LC-PUFA). Despite many years of research, essential fatty acids requirements in aquaculture nutrition are still not fully understood. Therefore, the work described herein was intended to determine the essentiality of C18 PUFA or LC-PUFA (including n-3 and n-6 fatty acids) in diets of hybrid Striped Bass and Rainbow Trout through survival, growth performance, and fatty acid tissue analysis. The essentiality in the two taxa were examined through feeding fish experimental diets that met all other nutrient requirements, except for fatty acid nutrition, for a period of 8 weeks. Diets were created to isolate individual fatty acids with hydrogenated soybean oil, rich in saturated fatty acids (SFA), and the absence or addition of various C18 PUFA or LC-PUFA fatty acid concentrates. An ideal fatty acid nutrition diet was formulated with 100% fish oil. Hybrid Striped Bass are reported to require EPA (eicosapentaenoic acid, 20:5n-3) and/or DHA (docosahexanoic acid, 22:6n-3) at 0.5-1% dietary inclusion rate. For all vertebrates, ARA (arachidonic acid, 20:4n-6) may also be important when determining LC-PUFA requirements. Results of this study indicate that hybrid Striped Bass do have a dietary requirement for LC-PUFA and that provision of C18 PUFA alone is insufficient to avoid essential fatty acid deficiency and support optimal growth of this fish. Existing fatty acid requirements for Rainbow Trout are 0.7-1.0% 18:3n-3 (alpha linolenic acid, ALA) and/or 0.4-0.5% n-3 LC-PUFA. It is debated whether Rainbow Trout require C18PUFA or LC-PUFA. Results of this study indicate Rainbow Trout are physiologically able to synthesize LC-PUFA from C18PUFA. Therefore, Rainbow Trout do not require LC-PUFA-rich feeds, but providing preformed LC-PUFA in the diet may be energetically advantageous and support improved growth performance. Quantitatively assessing essential fatty acid requirements in representative finfish will allow for more accurate formulations, but aquaculture is incredibly diverse and it will not be possible to conduct requirement students in all cultured taxa. The traditional formulation conventions for fatty acid requirements failed to recognize that the cold-water and marine species that had been evaluated were largely top-level carnivores, whereas the warm-water and freshwater species were largely herbivores, omnivores, or low level carnivores. In more recent work, the use of trophic levels to predict and generalize essential fatty acid requirements is gaining credence. Utilizing the trophic hierarchy ideology to guide EFA requirements may provide more accurate formulation. However, more research on various taxa is needed to determine the exact threshold at which PUFA essentiality, specifically requirements for C18 PUFA vs. LC-PUFA, can be predicted.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have indicated the level of total sulfur amino acids (TSAA)(methionine + cystine) is most limiting in practical diet formulations for hybrid striped bass(HSB), especially if animal feedstuffs are replaced with plant feedstuffs. Reduction of costly animal feedstuffs such as fish meal while maintaining adequate dietary levels of TSAA may enhance cost effectiveness of production. Therefore, this study, consisting of four separate feeding trials, investigated three different aspects of sulfur amino acid nutrition of HSB including: (1) the efficacy of crystalline methionine hydroxy analog (MHA) and liquid MHA(Alimet[superscript]TM) relative to L-methionine in meeting the requirement for TSAA; (2) the cystine sparing value for methionine; and, (3) the influence of various sulfur amino acid supplements on ammonia excretion. During the feeding trials, juvenile HSB were fed various diets including a basal diet deficient in TSAA (0.33 or 0.51% of diet), and experimental diets supplemented on an equal sulfurbasis with different levels of either L-methionine, Alimet[superscript]TM or crystalline MHA. Diets containing TSAA at 1% of diet and different ratios of cystine to methionine (60:40, 55:45,50:50, and 45:55) also were fed to re-evaluate sparing effects of cystine on methionine. During the ammonia excretion trial, HSB were fed diets containing either L-methionine, Alimet [superscript]TM or crystalline MHA after which total ammonia nitrogen (TAN) excretion was determined 4 h postprandial. In trial 1, Alimet [superscript]TM was 73% as effective in promoting growth as L-methionine at the same concentration while MHA was 83% as effective. In trial 3, fish fed Alimet [superscript]TM at 1.25% of diet displayed similar growth performance as those fed TSAA at 1.0% of diet while weight gain of fish fed Alimet [superscript]TM at 1% was only 58% of that displayed by fish fed TSAA at 1.0%. No significant differences in weight gain, feed utilization or survival were observed among fish fed diets containing various ratios of cystine to methionine although the diet with 60:40 cystine to methionine supported the lowest responses. Inclusion of MHA or Alimet [superscript]TM did not affect TAN excretion of HSB. These findings will aid in refining diet formulations for HSB to ensure adequate sulfur amino acid nutrition.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The US hybrid striped bass (Morone chrysops x M. saxatilis) industry has been negatively impacted by infectious diseases because there are very few approved drugs and vaccines. Therefore, a series of experiments was conducted to explore the potential use of various dietary supplements including autolyzed brewers yeast, the commercial prebiotic GroBiotic®-A, oligonucleotides and levamisole for improvement of hybrid striped bass growth, immunity and resistance to disease caused by various pathogenic bacteria. In two trials with brewers yeast, fish fed diets supplemented with yeast at 2% generally showed enhanced weight gain and feed efficiency compared with those fed a basal diet. Brewers yeast also positively influenced resistance to S. iniae infection. In addition, results of immune response assays demonstrated that brewers yeast can be administered for relatively long periods without causing immunosuppression. GroBiotic®-A (Grobiotic [superscript]TM AE) also resulted in significantly enhanced weight gain, innate immune responses and resistance of juvenile hybrid striped bass to S. iniae infection. An additional experiment with sub-adult fish showed significantly reduced mortality of fish fed a diet supplemented with GroBiotic®-A at 2% when subjected to an in-situ Mycobacterium marinum challenge. This is the first report of positive effects from dietary prebiotics for fish health management, although many fundamental questions should be pursued further. Dietary supplementation of a commercial oligonucleotide product (Ascogen P®) at 0.5% of the diet was shown to enhance resistance of hybrid striped bass against S. iniae infection and increased their neutrophil oxidative radical production. However, the effect on growth was marginal. Dietary levamisole supplementation at a low level (100 mg/kg) enhanced the growth and feed efficiency of juvenile hybrid striped bass. However, an elevated dosage(1000 mg/kg diet) strongly suppressed growth, feed intake and feed efficiency. Hypothesized beneficial influences, including antibody production and resistance to S.iniae and A. hydrophila were not substantiated. Although dietary levamisole increased fish macrophage respiratory burst, an in vitro study failed to show a direct effect on cultured macrophages. This suite of studies demonstrated the potential use of some dietary supplements to enhance hybrid striped bass production. Thus, immunonutrition represents a valuable strategy to apply in aquaculture.
