Book Description
Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

Book Description
Suriname is undoubtedly the site of origin of the oldest extant preserved specimens of South American fishes and 19 Surinamese fish species were described and figured by Linnaeus. This book offers the first comprehensive introduction to the 480 currently known fresh- and brackish-water fishes of Suriname, including identification keys, short descriptions and photographs of the species and descriptions of their habitats.

Book Description
Livestock farming supports livelihood and provides food security. It is the fastest-growing sector of the agriculture economy. This book is about using modern technology to increase yields, income, and ultimately food security. It is organized into three sections on livestock and poultry farming, fish farming, and innovations and advances in technology.

Book Description
This volume is taken from an ecological study of wetlands undertaken in northern Lake Victoria (East Africa) between 1993 and 1996 with the major aim of characterizing shallow vegetation-dominated interface habitats, and evaluating their importance for fish, in particular, for the Nile tilapia.

Book Description
This new volume examines the ecological importance, threats, protection, and management of the biodiversity of freshwater ecosystems, such as lakes, ponds, rivers, streams, reservoirs, pools, and wetlands. As populations have been increasing exponentially, humans are using freshwater ecosystems severely, resulting in habitat destruction and breakdown. Environmental contamination, climate change, the introduction of harmful and invasive organisms, unplanned dredging and de-weeding processes, disposal of sewer systems in freshwater bodies, and badly planned water diversions are the leading causes of habitat loss in freshwaters. These impacts have led to significant decreases in the numbers and productivity of many freshwater species and decreased biodiversity in freshwater. This book presents a selection of primary research and review papers on several freshwater aquatic biodiversity studies, which involve evaluating plants, macroinvertebrates, macrophytes, benthic zones, and fish diversity in freshwater ecosystems. It provides an abundance of new information on freshwater biodiversity distribution, status, and patterns. Key features: Discusses the importance, threats, and management of biodiversity of freshwater ecosystems Provides detailed coverage of modern and updated techniques used in the evaluation and conservation of freshwater biodiversity Looks at the impact of pesticides pollution on freshwater environs, and on aquatic and terrestrial life Reviews how global climate change affects freshwater biodiversity Biodiversity of Freshwater Ecosystems: Threats, Protection, and Management promotes the enhancement and strengthening of freshwater protection and its unique biodiversity for scientists, policymakers, scholars, researchers, NGOs, and the public, providing necessary background knowledge and practical tools to help manage aquatic ecosystems and their biodiversity in a holistic manner.

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
Regular reporting and monitoring of fishery and aquaculture production using genetic information, i.e. using information on stocks, breeds, monosex groups, polyploids, products of modern biotechnology and hybrids, would allow aquaculturists to assess which breeds or strains could be most useful for production, and help fishery managers better manage and trace products from capture fisheries. Genetic information would be useful to both aquaculturists and fishery managers in assessing which stocks are under threat or endangered and in traceability requirements for the origin and handling of aquatic food products. However, the capacity and information requirements for incorporating genetic information into national and global statistics are significant and, in many cases, currently prohibitive. A key source of information for this paper was the reports currently being submitted to the FAO Fisheries and Aquaculture Department by countries as part of the process to produce the first report on The State of the World’s Aquatic Genetic Resources for Food and Agriculture (SoW AqGR). Through this country-driven process, FAO is receiving information on stocks, varieties, strains and other farmed types that are currently being used in aquaculture and fisheries or that are being actively researched for future use. The country reports will further attempt to include relevant policies and constraints relating to the collection and monitoring of genetic data.
