Book Synopsis Enrichment of Live Prey with Microparticles for the Enhanced Delivery of Water-soluble Nutrients to Marine Fish Larvae by : Matt Hawkyard
Download or read book Enrichment of Live Prey with Microparticles for the Enhanced Delivery of Water-soluble Nutrients to Marine Fish Larvae written by Matt Hawkyard and published by . This book was released on 2015 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the wild, marine fish larvae feed on copepods and other planktonic organisms. Copepods are often considered the "gold standard" for meeting the nutritional needs of cultured marine fish larvae; however, in captivity, marine fish larvae are generally fed cultured live prey, i.e. rotifers (Brachionus plicatilis) and/or Artemia sp., until they can be weaned onto artificial diets, which typically coincides with the end of the larval phase. Concentrations of certain water-soluble nutrients in rotifers and Artemia, notably taurine, may not be sufficient to meet the nutritional demands of some species of marine fish larvae. The delivery of low-molecular weight, water-soluble substances to aquatic organisms is challenging because these substances are rapidly lost from food particles when suspended in water, referred to as nutrient leaching. One solution to this problem is to encapsulate water-soluble substances within synthetic microparticles that are specifically designed to reduce nutrient leaching. Alternatively, water-soluble substances may be dissolved in the culture water of these organisms facilitating nutrient absorption or ingestion via drinking, hereafter referred to as the "dissolved method" of nutrient enrichment. In Chapter 2, I provide an overview of enrichment methods for cultured live prey and put particular emphasis on the enrichment of water-soluble compounds. In Chapters 3, 4 and 5, my co-authors and I evaluated the use of synthetic microparticles, liposomes and wax spray beads, for increasing the water-soluble nutrient concentrations (enrichment) of rotifers and Artemia with the intent to increase their nutritional quality for marine fish larvae. Furthermore, we compared microparticulate enrichment with dissolved methods whereby the nutrients were dissolved in the culture medium. Microparticle-enriched live prey were evaluated by: 1) using fluorescent techniques to investigate the ingestion and digestion of microparticles by live prey and 2) determining the growth performance of two species of marine fish larvae, northern rock sole (Lepidopsetta polyxystra) and California yellowtail (CYT: Seriola lalandi) in response to different enrichment methods for the water-soluble nutrient, taurine. Taurine was used as a model nutrient because taurine concentrations are low in cultured live prey, especially when compared to copepods, and because its was believed to be a growth-limiting nutrient for marine fish larvae. Taurine concentrations in rotifers and Artemia enriched with taurine-containing microparticles could be increased to levels reported in copepods. In Chapters 3 and 4, we found that northern rock sole larvae grew significantly larger, were more developed and had higher whole body taurine concentrations when fed rotifers enriched with taurine-containing microparticles when compared to control treatments. In Chapter 5, we found that CYT larvae fed taurine enriched rotifers showed increased growth (final dry weights) and had higher whole body taurine concentrations when compared to larvae fed unenriched rotifers but these differences were not apparent in the subsequent Artemia phase, suggesting that unenriched Artemia had sufficient taurine concentrations to allow compensatory growth of CYT. Differences and similarities are discussed between the efficacy of liposomes and wax spray beads for rotifer enrichment and subsequent nutritional effects on fish larvae. Ultimately, this research provides the first evidence of positive growth effects of liposome- and wax spray bead-enriched live prey on marine fish larvae as a result of enhanced delivery of water-soluble nutrients. The outcomes of these findings suggest that microparticles may be used as a research tool to assess the water-soluble nutrient deficiencies of cultured live prey for marine fish larvae. Furthermore, with further development, these methods may have application for commercial hatcheries and could result in improved production efficiencies and cost savings for these operations

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and authoritative synthesis on the successful production of fish larvae Success Factors for Fish Larval Production is a vital resource that includes the most current understanding of larval biology, in the context of larval production. The text covers topics such as how external (environmental and nutritional) and internal (molecular/ developmental/ physiological/ behavioral/ genetic) factors interact in defining the phenotype and quality of fish larvae and juveniles. The expert contributors review broodstock genetics and husbandry, water quality, larval nutrition and feeding, growth physiology, health, metamorphosis, underlying molecular mechanisms, including epigenetics, for development, larval behavior and environmental conditions. Compiled by members of a European Union-funded consortium of top researchers, Success Factors for Fish Larval Production provides a wide-range of authoritative information for the aquaculture industry and academia. In addition to a wealth of information, the authors review research and commercially applicable larval quality indicators and predictors. The successful production of good-quality fish larvae is of vital importance for fish farming and stock enhancement of wild fisheries: Includes contributions from a consortium of noted researchers and experts in the field Deals with on how to improve egg quality and larval production via broodstock management and nutrition Suggests ways to control the phenotype of juveniles and table-size fish via manipulations of the conditions of larval rearing (e.g., epigenetics) Includes ideas for optimizing diet composition, formulation, and technology Integrates knowledge and practical experience in order to help advancing excellence in aquaculture Success Factors for Fish Larval Production offers fish biologists, developmental biologists, physiologists and zoologists the most current and reliable information on the topic. All those working in fish aquaculture facilities and hatcheries in particular will find great interest to their commercial operations within this book.

Book Synopsis Digestive Physiology and Food Intake in Marine Fish Larvae by : Sofia Morais
Download or read book Digestive Physiology and Food Intake in Marine Fish Larvae written by Sofia Morais and published by LAP Lambert Academic Publishing. This book was released on 2012-07 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: A growth depressing effect of high dietary neutral lipid levels in cultured marine fish larvae has been reported. This may be the result of a decrease in the efficiency or activity of digestive enzymes, a reduction in absorption efficiency and/or a decrease in food intake. This book presents work that was carried out on commercially valuable species (Atlantic herring, Senegalese sole, European seabass and gilthead seabream), to investigate the effects of neutral lipid level and source (fatty acid composition) on some of these key factors. The results collectively indicate that lipid transport across the enterocytes may be more problematic when feeding high neutral lipid diets than lipid digestion, although both factors are likely to intervene. Results also suggest that food intake might be affected by the lipid source included in the diet. Therefore, the neutral lipid level in diets for marine fish larvae has a significant impact in several factors influencing growth but clearly it cannot be dissociated of its fatty acid composition, which appears to play a central role on the nutritional and physiological effects of dietary lipid, at the ingestion, digestion and absorption levels.
