Larval Fish Aquaculture

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.

Aquaculture continues to grow more rapidly than all other animal food-producing sectors. The gap between seafood supply and market demand suggests a great potential for aquaculture development to meet the needs of seafood consumers. Larval fish rearing is a bottleneck to supply sufficient quantity and high quality of fingerlings for grow-out production. This book aims to provide comprehensive references on larval fish aquaculture. Specifically, it attempts to update the recent development in larval fish feed and feeding, environmental manipulation and hatchery management and to suggest future research needs for improvement of production efficiency in larval fish culture. Currently no book of this kind is available to cover major issues in larval fish aquaculture from an environmental, biological and managerial perspective. This book starts from environmental factors including temperature, salinity and light, and then extends to the major biological and managerial issues in larval fish rearing including live feed production, feeding and digestion, gas bladder development, metamorphosis, cannibalism control and weaning strategies. This book will become a useful reference text for researchers and hatchery managers advancing knowledge in larval fish rearing and a supplementary textbook for advanced courses in larval fish biology and aquaculture.

Nutrition is particularly important in the healthy development of fish during their early-life stages. Understanding the unique nutritional needs of larval fish can improve the efficiency and quality of fish reared in a culture setting. Larval Fish Nutrition comprehensively explores the nutritional requirements, developmental physiology, and feeding and weaning strategies that will allow aquaculture researchers and professionals to develop and implement improved culture practices. Larval Fish Nutrition is logically divided into three sections. The first section looks at the role of specific nutrient requirements in the healthy digestive development of fish. The second section looks at the impacts if nutritional physiology on fish through several early-life stages. The final section looks at feeding behaviors and the benefits and drawbacks to both live feed and microparticulate diets in developing fish. Written by a team of leading global researchers, Larval Fish Nutrition will be an indispensible resource for aquaculture researchers, professionals, and advanced students. Key Features: Reviews the latest research on larval fish nutritional requirements, developmental physiology, and feeding and weaning strategies Extensively covers nutritional needs of various early-life stages in fish development Weighs the benefits and drawbacks to both live feeds and microparticulate diets Written by a global team of experts in fish nutrition and physiology

This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the singlecelled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution. The book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

This book deals with the fundamentals of key physiological mechanisms involved in the development and growth of fish larvae. Chapters included show how the environmental and nutritional conditions are affecting the developmental process from its molecular basis and how these same conditions also influence the final characteristics of late larvae and fry. This volume provides recent findings on the importance of environmental rhythms, some specific nutrients and the adequate microbial environment in the developmental processes including recent results of current research projects.

As the expansion in world aquaculture continues at a very high rate, so does the need for information on feeding of cultivated fish and shellfish. In the larval and juvenile phases of many species, the use of manufactured feed is not possible. This important book covers in detail the biology and culture of the main live prey and microalgae used as feeds in the aquaculture of major commercial species including shrimps, sea bass, halibut, cod and bivalves. Contents include comprehensive details of the status of marine aquaculture in relation to live prey, and chapters covering the biology, production, harvesting, processing and nutritional value of microalgae and the main prey species: rotifers, Artemia and copepods. The editors have drawn together an impressive international team of contributors, providing a work that is set to become the standard reference and practical guide on the subject for many years to come. Live Feeds in Marine Aquaculture is an essential purchase for anyone involved in marine aquaculture, including fish farmers, researchers, and personnel in feed and equipment companies supplying the aquaculture trade. An extremely valuable tool as a reference and practical manual for students and professionals alike; libraries in all universities and research establishments where biological and aquatic sciences and aquaculture are studied and taught, should have copies available on their shelves.

The importance of copepods in aquaculture has long been recognized, especially in the larval rearing of many marine fishes. This timely publication provides a single source of information on copepod biology, culture methods and practical use in marine finfish hatcheries. Originating out of a workshop held on copepods by the Oceanic Institute in Hawaii, this proceedings includes review articles and papers presented by leading international experts in copepod biology and aquaculture. It is a seminal work that integrates the most up-to-date information on selecting copepod species, effects of algal species on reproduction, ways to increase production, the nutritional value of copepods, behavioral characteristics of copepods, potential use of copepod nauplii and eggs, and their application to larval rearing of various marine finfish species.
