Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book is a unique cross fertilization of aquatic ecology and aquaculture. It shows how diets structure the digestive tract and its microbiota and, in turn, the microbiota influences life history traits of its host, including behavior. Short-term starvation can have beneficial effects on individuals themselves and succeeding generations which may acquire multiple stress resistances - a mechanism strengthening the persistence of populations. From terrestrial, but not yet from aquatic animals, it is understood that circadian the rhythmicity makes toxins or good food. On the long-term, the dietary basis impacts succeeding generations and can trigger a sympatric speciation by (epi)-genetics.This volume defines gaps in nutritional research and practice of farmed fishes and invertebrates by referring to knowledge from marine and freshwater biology. It also points out that dietary benefits and deficiencies have effects on several succeeding generations, indicating that well designed diets may have the potential to successfully improve broodstock and breeding effort.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Based on positive experiences in human nutrition and healthy aging, individual and combined plant secondary metabolites are added to aquafeeds. The main compounds used are carotenoids, polyphenols, terpenes, and various alkaloids. The pile of supplementation studies with beneficial results is growing rapidly. These benefits include increased immunity, pathogen resistance, or improved gut microbiome diversity. However, a variety of adverse results cannot be ignored. Overall, inAquatic Animal Nutrition research, this is another area of that is still in its early stages: as with supplementation of plant preparations (Aquatic Animal Nutrition Plant Preparations), a robust and guiding hypothesis for supplementation is not apparent, and graded dosing is rarely used, especially in the low-dose range. Often, the high doses used lead to the classification of various compounds as anti-nutritional. However, appropriate low-dose supplementation demonstrates that and how aquatic animals can cope with anti-nutritional factors within their adaptive response, indicating that even these compounds may have some nutritional value. In addition, knowledge of the underlying mechanisms of the adaptive response may provide physiological, transcriptomic, and epigenetic means to more sustainably utilize even this worthless food source. 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. Supplementing aquafeed with terrestrial plant material can introduce toxins and endocrine disruptors. The addition of adsorptive compounds (clay minerals) or functional feed ingredients (prebiotics, probiotics) can at least partially mitigate the adverse effects.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Not all stress is stressful; instead, it appears that stress in the environment, below the mutation threshold, is essential for many subtle manifestations of population structures and biodiversity, and has played a substantial role in the evolution of life. Intrigued by the behavior of laboratory animals that contradicted our current understanding of stress, the author and his group studied the beneficial effects of stress on animals and plants. The seemingly 'crazy' animals demonstrated that several stress paradigms are outdated and have to be reconsidered.The book describes the general stress responses in microorganisms, plants, and animals to abiotic and biotic, to natural and anthropogenic stressors. These stress responses include the activation of oxygen, the biotransformation system, the stress proteins, and the metal-binding proteins. The potential of stress response lies in the transcription of genes, whereas the actual response is manifested by proteins and metabolites. Yet, not all stress responses are in the genes: micro-RNAs and epigenetics play central roles. Multiple stressors, such as environmental realism, do not always act additively; they may even diminish one another. Furthermore, one stressor often prepares the subject for the next one to come and may produce extended lifespans and increased offspring numbers, thus causing shifts in population structures.This book provides the first comprehensive analysis of the ecological and evolutionary effects of stress.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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 supplementation is not apparent. Therefore, the book proposes the use of artificial intelligence to end thetrial-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.…
