Aquatic Animal Nutrition

<p>This volume first covers the supplementation of aquafeeds with terrestrial plant material used in human medicine and nutrition. Mainly based on the ���trial and error��� approach many supplements enhance growth immunity and resistance to stress. However other supplements appear to be ineffective and some have adverse effects. A robust and guiding hypothesis for sup��plementation is not apparent. Therefore the book proposes the use of artificial intelligence to end the trial-and-error phase. In addition a graded dosing is rarely used especially in the low-dose range so the physiological mechanisms behind the supplements are often only partially understood. This topic of aquatic animal nutrition is still in its infancy. Chapters cover medicinal plants in general selected medicinal plants in detail food plants fruits essential oils fermentation residues and genetically modified plants. One chapter attempts to answer the question of what mechanism may underlie ineffective or even harmful supplementation. Overall the importance of the intestinal microflora is becoming increasingly clear and points to the imperative need to include gut microbiota in replacement studies. Based on the few epigenetic studies currently available the importance of these processes is demonstrated. The need to integrate such approaches into future studies is emphasized. The so-called hologenomics approach is inevitable. Can adverse effects be mitigated by adding functional feed ingredients such as prebiotics or probiotics? This volume concludes with aquatic plants (macroalgae filamentous algae and macrophytes) as food sources for natural and farmed aquatic animals. Can aquaculture learn from natural aquatic herbivores?  </p>
