There is considerable global interest in the culture of finfish species both for cold and warm water aquaculture development and growth. Essential information on the biology, domestication and aquacultural characteristics of a wide selection of novel and established species is provided in the form of technical sheets, species descriptions and information on current rearing practices, making this a must-have reference in the field of aquacultural science. The book also offers a basic framework in order to support investment strategies for research and development efforts aimed at the emergence of a profitable finfish aquaculture industry and presents a rationale for species diversification, different approaches to species selection and basic economic and market considerations governing the launch of strategic development and commercialization efforts.

While diversified aquaculture could reduce both biological and financial risks, the private sector may lack incentives to diversify the species composition of aquaculture production because developing or adopting new species tends to be costly and risky. Conversely, concentrating on the most efficient species can benefit from economies of scale in both production and marketing. With ever-growing concerns over climate change, disease outbreaks, market fluctuations and other uncertainties, species diversification has become an increasingly prominent strategy for sustainable aquaculture development. Policy and planning on species diversification require a holistic, sector-wide perspective to assess the overall prospect of individually promising species that may not be entirely successful when competing for limited resources and markets. The historical experiences of species diversification in global aquaculture can provide guidance for the assessment. This paper develops a benchmarking system to examine species diversification patterns in around 200 countries for three decades to generate information and insights in support of evidence-based policy and planning in aquaculture development. The system uses “effective number of species” (ENS) as a diversity measure that is essentially equivalent to, yet more intuitive than, the widely used Shannon Index. A statistical model is established to estimate a benchmark ENS for each country and construct a benchmarking species diversification index (BSDI) to compare a country’s species diversification with global experiences. Key results are presented and discussed in the main text; and more comprehensive results are documented in Appendix II. The benchmarking system can be used in foresight analyses to help design or refine future production targets (including species composition) in policy and planning for aquaculture development; an example is provided in Appendix I to help practitioners better understand and utilize the system.
FAO Fisheries and Aquaculture Proceedings These proceedings, from a workshop convened by FAO and World Fisheries Trust (Canada), summarize diversification successes and opportunities in all major world regions, and identify general principles to guide diversification in aquaculture.The document includes an assessment of main strategies and future steps, not only in terms of purely economic costs but also in development costs, including evaluation and mitigation of environmental and social impacts and establishment of species-specific biosecurity frameworks.
This two-volume set discusses recent approaches and technological innovations for sustainable agriculture in smallholder farming systems impacted by climate change. The systems covered include crop-based agricultural production, as well as aquaculture and livestock production as related systems using similar techniques to combat food security issues brought about by climate change and resource overuse. The chapters detail innovations involving crop diversification, soil resilience management, geoinformatics and land suitability monitoring for smart farming, information technology in livestock production, and nutrient resource management in fishery aquaculture. Researchers, practitioners and industries will be able to use this information to implement socially and economically sustainable practices to achieve food security in impoverished areas vulnerable to climate change, while also learning about the rapid evolution in information technology that is applicable for and available to small holder farmers. Volume 1 focuses on current innovations in agricultural and livestock practices in response to climate change. It covers the technological challenges, approaches and mitigation strategies encountered by both scholars and practitioners working in livestock and agricultural production systems impacted by climate change.
Modern aquaculture is faced with a number of challenges, including public concern about environmental impacts and the welfare of farmed fish. A fundamental understanding of fish biology is central to finding ways to meet these challenges and is also essential for maintaining the industry's sustainability. Furthermore, the behaviour of fish under culture situations has long been ignored despite heavy commercial losses that can result from fish stressed and hence disease-prone, due to bad husbandry techniques. This important book summarises the current understanding of the behavioural biology of farmed species and illustrates how this can be applied to improve aquaculture practice. Informative and engaging, Aquaculture & Behavior brings the reader up-to-date with major issues pertaining to aquaculture. Everyone from fish farmers to upper level students will find this book a valuable and practical resource. Libraries in universities and research establishments where animal behavior, aquaculture, veterinary and biological sciences are studied and taught should have copies of this work on their shelves.
Aquaculture is a rapidly growing, successful approach to improving diets by providing more high quality fish and shellfish protein. It is also an industry with major unresolved issues because of its negative impact on the environment. This book is a pioneering effort in the development of environmentally benign aquaculture methods.
Focusing on pathobiology and protective strategies against protozoan and metazoan parasites of fish, this book reviews the latest research on important parasites: those that cause financial hardships to the aquaculture industry, have been introduced to new geographical regions through transportation of infected fish, are pathogenic to groups of finfish and detrimental to production, are highly adaptable and not host-specific with worldwide distributions, and that may serve as disease models for studies on other pathogens. It also highlights gaps in the knowledge to help direct future research.
This book investigates how fish experience their lives, their amazing senses and abilities, and how human actions impact their quality of life. The authors examine the concept of fish welfare and the scientific knowledge behind the inclusion of fish within the moral circle, and how this knowledge can change the way we treat fish in the future. In many countries fish are already protected by animal welfare legislation in the same way as mammals, but in practice there is still a major gap between how we ethically view these groups and how we actually treat them. The poor treatment of fish represents a massive animal welfare problem in aquaculture and fisheries, both in terms of the number of animals affected and the severity of the welfare issues. Thanks to its interdisciplinary scope, this thought-provoking book appeals to professionals, academics and students in the fields of animal welfare, cognition and physiology, as well as fisheries and aquaculture management.
