Book Description
As the world's demand for food from aquatic environments continues to increase, the importance of performing aquaculture in an environmentally responsible manner also increases. The aim of this important and thought-provoking book is to stimulate discussion among aquaculture's modern scientific, education and extension communities concerning the principles, practices and policies needed to develop ecologically and socially sustainable aquaculture systems worldwide. Ecological Aquaculture provides fascinating and valuable insights into primitive (and often sustainable) culture systems, and ties these to modern large-scale aquaculture systems. The book is edited, and authored to a considerable degree, by Barry Costa-Pierce who has assembled a team of some of the leading thinkers in the field, providing information spanning a spectrum of activities from artisanal to high technology approaches to producing aquatic organisms in a balanced and environmentally-friendly way. Ecological Aquaculture is an essential purchase for all aquaculture personnel involved in commercial, practical and research capacities. Libraries in research establishments and universities where aquaculture, biological, environmental and aquatic sciences are studied and taught should have copies of this book available on their shelves.

Book Description
In this volume, an international group of contributors explores the newly emerging aquaculture industry. Focusing on the social and environmental dimensions of aquacultural development in both industrialized and nonindustrialized nations, they examine issues of social equity, user-group conflict, environmental impacts of production, and the mediating role of the state. They also discuss aquaculture's role in development activity-especially in sustainable development, where it can enhance community viability, coherence, and solidarity. Asserting the need for careful planning and recognizing impending political and moral choices, the contributors assess the decisionmaking process for public authorities and development agencies and consider the social consequences of these decisions. Policymakers responsible for promoting and managing this growing industry will find this volume invaluable as they begin to research and design appropriate institutional structures. In addition, scholars interested in the overall adoption and diffusion of new technologies will find here a rich source of information about a system that shares attributes with but also differs significantly from agricultural and fisheries production systems.

Book Description
Papers in this book discuss the emphasis on tilapia, modelling of pond aquaculture, exploratory and confirmatory methods for multivariate analysis, the relationships between multiple regression and analysis of variance and the rationale for sharing and analyzing "old", public domain data, all with emphasis on tropical/subtropical aquaculture systems.

Book Description
Aquaculture technology has been evolving rapidly over the last two decades, led by an increasingly skilled cadre of researchers in developing countries. Rather than copying, or adapting work done in industrialized countries to their situations, these scientists are moving aquaculture research out of the box to explore species and production systems relevant to their natural resources, economies and social institutions. Studies from India, Latin America, the Middle East and Africa are highlighted in this collection of papers, covering the entire gamut of aquaculture science from comparison of tilapia breeds, novel feed ingredients for indigenous species, improving disease resistance, water-use efficiency, traditional farming systems, spatial planning and economics. More than a how-to book, this volume introduces the researchers and institutions leading the development of aquaculture as it expands into new frontiers. This book was based on a special issue of the Journal of Applied Aquaculture.

Book Description
Volume 3. This document identifies elements of a legislation that will encourage the emergence of a sustainable commercial aquaculture. The aquaculture law of an individual country must provide the operator with a secure right to conduct aquaculture operations, to the property on which the farm will be located, to good quality water and to the produce. It must also ensure environmental sustainability, through permit or licence systems, without imposing unnecessary costs on applicants. Only proposals with the potential for serious environmental harm should be subjected to a full environmental impact assessment. Environmental supervision must extend to controls over the use of exotic species and products from modern biotechnology including genetically modified organisms, disease control and health management and to any water quality concerns created by the proposed project. To minimise costs, countries are encouraged to adopt a single window approach for the numerous approvals usually required for an aquaculture operation and screen initial applications. They could also consider creating a single agency to promote aquaculture and to monitor the progress of applications. Aquaculture regimes of selected African countries are measured against the elements required to encourage sustainable commercial aquaculture, and improvements that are applicable to all countries in sub-Sahara are suggested.

Book Description
"(Reprint. First published in 1998) The present study is an update of an earlier assessment of warm-water fish farming potential in Africa, by Kapetsky (1994). The objective of this study was to assess locations and areal expanses that have potential for warm-water and temperate-water fish farming in continental Africa. The study was based on previous estimates for Africa by the above author, and on estimates of potential for warm-water and temperate-water fish farming in Latin America by Kapetsky and Nath (1997). However, a number of refinements have been made. The most important refinement was that new data allowed a sevenfold increase in resolution over that used in the previous Africa study, and a twofold increase over that of Latin America (i.e. to 3 arc minutes, equivalent to 5 km x 5 km grids at the equator), making the present results more usable in order to assess fish farming potential at the national level. A geographical information system (GIS) was used to evaluate each grid cell on the basis of several land-quality factors important for fish-farm development and operation regardless of the fish species used. Protected areas, large inland water bodies and major cities were identified as constraint areas, and were excluded from any fish farming development altogether. Small-scale fish farming potential was assessed on the basis of four factors: water requirement from ponds due to evaporation and seepage, soil and terrain suitability for pond construction based on a variety of soil attributes and slopes, availability of livestock wastes and agricultural by-products as feed inputs based on manure and crop potential, and farm-gate sales as a function of population density. For commercial farming, an urban market potential criterion was added based on population size of urban centres and travel time proximity. Both small-scale and commercial models were developed by weighting the above factors using a multi-criteria decision-making procedure. A bioenergetics model was incorporated into the GIS to predict, for the first time, fish yields across Africa. A gridded water temperature data set was used as input to a bioenergetics model to predict number of crops per year for the following three species: Nile tilapia (Oreochromis niloticus), African catfish (Clarias gariepinus) and Common carp (Cyprinus carpio). Similar analytical approaches to those by Kapetsky and Nath (1997) were followed in the yield estimation. However, different specifications were used for small-scale and commercial farming scenarios in order to reflect the types of culture practices found in Africa. Moreover, the fish growth simulation model, documented in Kapetsky and Nath (1997), was refined to enable consideration of feed quality and high fish biomass in ponds. The small-scale and commercial models derived from the land-quality evaluation were combined with the yield potential of each grid cell for each of the three fish species to show the coincidence of each land-quality suitability class with a range of yield potentials. Finally, the land quality-fish yield potential combinations were put together to show where the fish farming potential coincided for the three fish species."
