Tropical Mariculture takes an in-depth look at developmental activities in a growing industry striving towards sustainability and environmental integrity. All of the contributors to this book have considerable experience and expertise in the field of tropical mariculture, and this is the first book to bring expert contributions together. The topics covered are wide and varied, ranging from general issues such as the impact of mariculture on coastal ecosystems to genetic improvement of cultured marine species, as well as the specifics of breeding selected marine species of current importance, such as groupers and sea bass. Significant coverage is also given to the problems of larval rearing in inland aquaculture as well as the demands of water- and land-based resources in a tropical environment. This book will be essential for everyone working in and researching tropical mariculture. - Looks at developmental activities in tropical mariculture - All of the contributors are experts in the field - Covers specific breeding problems and larval rearing - Studies the environmental impact of inland aquacultural activities - Provides detailed examples of cultivated species in the tropics - Compiles mariculture strategies and discusses example species - First book to give an overview of tropical mariculture
This document is directed to aquaculture development specialists, coastal resource use planners and government officials involved and interested in the planning and management of coastal aquaculture development within the wider context of resource use in coastal areas. It is intended to serve in the promotion of environmental management of coastal aquaculture. Guidelines are given for improved environmental management of coastal aquaculture based on an overview of selected published experiences and concepts. Potential adverse environmental effects of and on coastal aquaculture practices are addressed with consideration of main socio-economic and bio-physical factors. Methodologies are presented for the assessment and monitoring of environmental hazards and impacts of coastal aquaculture. Selected environmental management options are described for application both at policy-level and farm-level.
Carrageenan is a gelling agent extracted from red seaweeds and it has multiple applications in the food processing and other industries. Increasing demand for carrageenan has led to rapid expansion of carrageenan seaweed (primarily Kappaphycus and Eucheuma) farming in tropical areas. This expansion is expected to continue, but many issues need to be addressed to enable the sector to develop its full potential in contributing towards sustainable livelihoods, human development and social well-being. Including six country case studies and a global synthesis, this document provides a comprehensive and balanced assessment of the economic, social and governance dimensions of carrageenan seaweed farming. Information and insights provided by this document should facilitate evidence-based decision-makings in both the public and private sectors.
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.
Aquaculture is the art, science and business of cultivating aquatic animals and plants in fresh or marine waters. It is the extension of fishing, resulted from the fact that harvests of wild sources of fish and other aquatic species cannot keep up with the increased demand of a growing human population. Expansion of aquaculture can result with less care for the environment. The first pre-requisite to sustainable aquaculture is clean wate, but bad management of aquatic species production can alter or even destroy existing wild habitat, increase local pollution levels or negatively impact local species. Aquatic managers are aware of this and together with scientists are looking for modern and more effective solutions to many issues regarding fish farming. This book presents recent research results on the interaction between aquaculture and environment, and includes several case studies all over the world with the aim of improving and performing sustainable aquaculture.
Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.
U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.
Environmental risks associated with large-scale marine finfish cage aquaculture cast doubt on the sustainability of the industry. This book divides the topic into its broad parts: Eutrophication; Sedimentation and Benthic Impacts; Changes in Trophic Structure and Function; and Managing Environmental Risks, and goes further to analyze methods and models currently used to measure near and far-field environmental effects of finfish mariculture and and their implications for management.
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.
