Tilapias: Biology and Exploitation


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.










Aquaculture Sourcebook


Book Description

As traditional commercial fishing becomes increasingly expensive and restrictive, aquacultural fish production emerges as a practical viable alternative. The Aquaculture Sourcebook is an introductory text and ready reference for information on the fresh-, brackish-, and salt-water farming of both fish and shellfish, as well as of several important algae. Until now, such material has been available only in scattered publications; but the Aquaculture Sourcebook incorporates all the feasibility data pertinent to farming aquacultural species in North America into one easy-to-use text. It will be welcomed not only by current and future aquaculturists, but also by fisheries, seafood company managers, biologists, teachers, and students. The Aquaculture Sourcebook has been designed to satisfy the needs of fisheries, scientists, and commercial aquaculturists by providing, in a handy and well-organized format, information vital for successful North American aquacultural ventures. Concise details are given for over a hundred individual speices, including not only those raised for human consumption, but also organisms reared for feed, bait, or other purposes. Each entry in this valuable volume covers such relevant material as: *the scientific and common names of the organism *its visual appearance and distinctive characteristics *habitat range specifications *species reproduction and development *age- and growth-related factors *specific parasites an diseases *potential predators and/or competitive species *its prospects for future aquacultural success Key groups of closely related species are discussed in a geographical context, highlighting areas which each will find the habitat best for its survival. Great care has been taken to specify ranges of tolerable salinity and optimum temperature for candidate species, and emphasis has been placed on creating aquacultural environments that replicate those normally habitated in nature. Comprehensive, informative, and accessible to layperson and scientist alike, the Aqualculture Sourcebook is both the perfect desktop reference for anyone establishing an aquacultural facility, and a ready reference to help maintain one.




Intensive Animal Farming - A Cost-Effective Tactic


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.




The Freshwater Fishes of Suriname


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.




The Biology and Culture of Tilapias


Book Description

This conference brought together 19 tilapia biologists and experimental culturists from 10 countries. It was designed from the outset as a technical conference on the basic biology of the tilapias and applications in culture systems. The conference did not consider the commercial aspects of tilapia culture.




Lake Victoria Wetlands and the Ecology of the Nile Tilapia


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.




Risk analysis in aquaculture


Book Description

This publication is based on materials covered and outputs generated during the Workshop on Risk Assessment Methodologies and Tools for Aquaculture in Sub-Saharan Africa, which was jointly held by WorldFish and FAO in Siavonga, Zambia on 28 June - 2 July 2010. The workshop was delivered as a training exercise to 17 participants from seven sub-Saharan countries and was designed to highlight current methodologies and tools available for environmental risk analysis in aquaculture development. A key focus of the workshop was to encourage participants to consider hypothetical but realistic scenarios and to discuss issues relevant to evaluating the environmental risks of a given activity or scenario. This publication presents selected scenarios from the workshop and the outcomes of the deliberative process as developed by the participants. This publication is factual but not comprehensive, therefore any statements or estimations of risk do not represent the actual risks arising from the described scenario. It is intended to serve as an easily readable introduction to risk analysis, highlighting worked examples that will provide guidance on how a risk analysis may be approached in a similar situation.ÿ
