This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Las necesidades nutricionales de los reproductores de dorada han sido poco estudiadas, esto unido al comportamiento reproductor imprevisible y variable de las especies en cautividad, constituyen un importante factor limitante para la producción masiva de semilla. La adecuada alimentación de los reproductores no solo puede mejorar la calidad de huevos y espermatozoides sino también aumentar la producción de semilla. El objetivo general de este trabajo fue el de realizar una aproximación al efecto de la inclusión de sustancias bioactivas como los carotenoides, en la dieta de los reproductores de dorada (Sparus aurata), y su relación con otros micronutrientes (n-3 HUFA y vitamina E) sobre la calidad de la puesta de esta especie bajo condiciones de cultivo. Se evaluaron los efectos de dietas experimentales, sobre el número de huevos producidos, morfometría de los mismos, viabilidad, número de larvas eclosionadas y supervivencia larvaria, entre otros. En forma paralela se estudió, la composición bioquímica de los huevos y su relación con la dieta suministrada, y con la calidad de la puesta. Se realizaron una serie de experimentos, todos ellos con un diseño experimental muy similar entre sí, los objetivos específicos de los experimentos realizados fueron: evaluar el efecto de la utilización de carotenoides de distinto origen; determinar el requerimiento de carotenoides en dietas isoprotéicas e isolipídicas; evaluar el efecto de la inclusión de carotenoides y distintos niveles de n-3 HUFA y evaluar el efecto de la inclusión de Vitamina E y carotenoides en la dieta. Los resultados de este trabajo sugieren que la calidad de la puesta de la dorada puede mejorarse por la inclusión de carotenoides dietéticos. La inclusión de carotenoides, como el pimentón en polvo, de origen vegetal, produjo mejores resultados en la calidad de la puesta que la harina de langostino, de origen animal. Esto se podría deber al tipo de carotenoides que determinan también la calidad nutricional. La ca

Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
Book Synopsis Broodstock Management and Egg and Larval Quality by : Niall R. Bromage
Download or read book Broodstock Management and Egg and Larval Quality written by Niall R. Bromage and published by Wiley-Blackwell. This book was released on 1995-02-17 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the supply of eggs and fry is one of the major constraints on future aquaculture development. For the majority of farmed species, production is totally dependent on harvesting of broodstocks or seed from wild populations At present we know little about the control of reproduction of most farmed finfish nor of the detailed nutrient, metabolic and husbandry requirements of the broodstock or the ways in which they might be managed to optimize seed production and improve the quality of eggs and larvae. Newer technologies such as ploidy and gender manipulation, induced spawning and cryopreservation are coming to the forefront of modern broodstock management and all of these topics are considered, in detail, in this new text. Broodstock Management and Egg and Larval Quality has been written as a standard text for commercial practitioners and students of aquaculture, fish biology and fisheries and provides a comprehensive review of current and future methods of broodstock and hatchery management. The range of marine and freshwater tropical and temperate finfish species considered, together with contributions from many of the world's most eminent fish biologists, provide comprehensive and international coverage of this increasingly important area of aquaculture.
