Sustainable Aquafeeds

Aquaculture, the youngest, fastest-growing, and most dynamic protein-producing industry, has the key advantage of efficient use of feed that allows farmed fish to be competitively priced compared with terrestrial proteins. Sustainable Aquafeeds: Technological Innovation and Novel Ingredients explores the present and future evolution of feeds, explains the current challenges for aquaculture, and considers how advances in technologies and ingredients can produce aquafoods for the increasing world population. International contributors to this book provide state-of-the-art information on the profile of the aquafeed industry, including factors affecting supplies and prices of key ingredients for aquafeed production. An entire set of chapters covers the scientific advances and feed industry initiatives in accordance with modern consumer trends, updating readers on the most promising strategies. These include the use of novel ingredients for nutrient supplementation and the enhancement of their use by genetic selection. The authors hope to inspire a collaboration of NGOs, researchers, and private partnerships to replace wild-caught ingredients by accelerating and supporting the scaling of innovative, alternative, aquaculture feed ingredients, including bacterial meals, plant-based proteins, algae, and yeast.

This book is about important relevant recent research topics in sustainable aquaculture practices. A critical assessment of the sustainable fishing methods and the aspect of sustainable aquaculture feed is presented in this volume. A special focus has been given to socio-economic and environmental assessment of aquaculture practices and analysis of carbon footprint under an intensive aquaculture regime. Aquaponics as a niche for sustainable modern aquaculture has been highlighted. The effect of use of pharmaceuticals to prevent fish disease on the surrounding marine environment is an emerging area of concern, and a critical discussion on this aspect is included in the book. The spread of organic waste and nutrients released by fish farms to natural water bodies has raised considerable concerns. Therefore the methods to prevent their dispersion and removal (treatment) have been comprehensively covered in this book. This book is an essential read for academician, researchers, and policy makers in the field of aquaculture.

Future Food Systems: Exploring Global Production, Processing, Distribution and Consumption provides an overview of food systems, from farming through to logistics, processing, retail, service and consumption, with the intention of enabling more efficient development of policy and implementation of food related practices. The book presents the considerations which must be understood to develop effective and efficient policies and practices for any level of food system and along the continuum of those systems, with attention being given to the academic, public and private sector challenges, and opportunities for progress, efficiency, effectiveness, and sustainability. Presented in parts to highlight key aspects of the subject area, the book explores production practices including increasingly important programs in integrated farming systems, vertical agriculture and urban farming, processes, value adding for commodities, agricultural technology, supply chain innovations and consumer considerations. The book provides foundational insights into the underpinnings of today’s food systems, its challenges and its opportunities for the future. Written by industry and academic experts for balanced perspective Presents foundational information with practical application insights Includes chapters on regulatory and policy issues

The global human population will reach nine billion by 2050, and seafood is projected to be the primary food source to sustain such a large population. According to a recent World Bank report, aquaculture will be the prime source of seafood by 2030. Tilapia is one of the promising species for commercial aquaculture and one of the second most farmed fish worldwide. Given the issues raised by Antibiotic misuse in intensive aquaculture, such as the occurrence of resistant bacteria, it is necessary to develop environment-friendly strategies that could be used to improve production in a sustainable manner. Also, there is a need to establish the best aquaculture practice (BAP) approaches to avoid significant disruption to the ecosystem, the loss of biodiversity, and substantial pollution impact on the environment. The book covers the recent findings regarding sustainable tilapia farming through environment-friendly approaches. This book contains chapters that cover the current status of world tilapia farming and the concept of sustainability of tilapia culture (Chap. 1). Chap. 2 discusses the health management of tilapia with a particular focus on various diseases and treatments. Chap. 3 provides an updated view of the possible effects of feed additives on tilapia reproductive performance. Chap. 4, 5, and 6 cover the recent findings on the gut microbiota of tilapia with a particular focus on structure and modulation. Chap. 7 focuses on the use of medicinal plants for sustainable tilapia farming. Chap. 8 provides insights into the application of alternative protein sources to decrease fish meal consumption. Chap. 9 highlights the importance of culture systems for the development of sustainable tilapia aquaculture. We believe the current book will be very helpful to academics, researchers, and policy-makers in aquaculture.

This special edition, Seafood Sustainability Series I, includes two articles on seafood consumption, four on sustainable capture fisheries, and four on sustainable aquaculture. The articles on consumption explore an alternative perspective on sustainable seafood movement governance to consumer- or retail/brand-driven logic and analyze fish tissues for human consumption to detect contaminants like flame retardant chemicals hazardous to human health sourced from microplastic pollutants. Articles on capture fisheries include: • A study of harvest strategies to achieve ecological, economic, and social sustainability objectives; • An examination of the economic leverages and resources needed to sustain coastal artisanal fishing communities in Africa; • A review of sustainability planning efforts to combat fishing community threats like declining participation, aging infrastructure and fleets, gentrification, reduced resource access, market competition, and environmental stresses; • An analysis of responsible fish consumption through a life-promoting sustainable food system for school-age children. Three of the articles on aquaculture focus on studying consumer preferences related to sustainable aquaculture based on the estimation of how the attributes of aquaculture products (including product labeling and perception) affect consumers’ purchase decisions. The other article questions the widely held assumption of sustainable substitutability of plant protein sources (e.g., soymeal) for fishmeal in aquaculture production.

This book provides a scientific forecast of development in aquaculture with a focus on the environmental, technological, social and economic constraints that need to be resolved to ensure sustainable development of the industry and allow the industry to be able to feed healthy seafood products to future generations. The chapters discuss the most critical bottlenecks of the development. They encompass subjects of understanding the environmental impacts, the current state-of-the-art in monitoring programs and in coastal zone management, the important interactions between wild and cultured organisms including release of non-native species into the wild.
