Tilapia: Biology, Culture and Nutrition.
By Chhorn Lim and Carl D. Webster (Editors), Hardcover 705 pages (May 2006).

Tilapia is the second-most cultured fish species in the world, and its production is increasing each year. However, for several reasons profit margins remain slim. Tilapia: Biology, Culture, and Nutrition presents respected international experts detailing every aspect of tilapia production around the world. Biology, breeding and larval rearing, farming techniques, feeding issues, post-harvest technology, and industry economics are clearly presented. This concise yet extensive reference provides the latest research and practical information to efficiently and economically maximize production in diverse locales, conditions, and climates. This book comprehensively explores all types of tilapia with a detailed biologic description of the fish that takes readers from egg through harvesting. The book authoritatively discusses production issues such as feed nutrition, temperature, water quality, parasites, and disease control to guide readers on how to best encourage fast, efficient growth. Economic and marketing information are examined, including industry data and projections by country. Each chapter approaches a specific facet of tilapia and provides the most up-to-date research available in that area. This resource gives the most current, detailed information needed for effective tilapia farming in one compact economical volume. Extensively referenced with an abundance of clear, helpful tables, photographs, and figures. Tilapia: Biology, Culture, and Nutrition is essential reading for aquaculturists, nutritionists, geneticists, feed formulators and mill operators, hatchery managers, tilapia growers and producers, educators and students etc.

Tilapia Culture.
By Abdel-Fattah M. El-Sayed, Hardcover 320 pages (June 2006).

This book describes, in detail, the principles and practice of tilapia culture. All aspects of the subject are covered, from basic biology, environmental requirements, nutrition and reproduction, to culture in intensive and semi-intensive systems. There is also discussion of stress and diseases, harvesting and marketing of farmed tilapia, the role of tilapia culture in rural development and environmental impact of tilapia culture. Tilapia are sometimes known as "aquatic chicken", due to their high growth rates, adaptability to a wide range of environmental conditions, ability to grow and reproduce in captivity and feed on low trophic levels. As a result, these fishes have become excellent candidates for aquaculture, especially in tropical and subtropical regions. Indeed, tilapia culture has been expanding rapidly, and is now practised in more than one hundred countries worldwide. This book is designed for students, researchers and practitioners in aquaculture.

Tilapia Culture.
By Stephen Goddard, Hardcover 320 pages (July 2007).

Tilapia are an extremely important food fish, caught and cultured throughout the world's sub tropical and tropical regions. The farming of tilapia has increased dramatically during the last decade with global production now exceeding 2,000,000 tonnes per annum; three-quarters of which is from aquaculture.This important new book provides a single key reference covering current methods of tilapia culture including full details of recent advances in methods of husbandry, reproductive technology and genetic improvement of strains for colour, growth, yield and development of new consumer products. Full information on the biological and environmental principles underlying sustainable aquaculture practices is also included.

Please note that we have closed from 15. July to 13. August due to vaccation.

Holding units with conditioner and recirculation system, for fish and seafood -

An aquarium should be seen as a complex grouping of elements functioning synergetically to maintain constancy of environmental characteristics, countering any variation whatsoever and simulating as far as possible the whole biological cycle that is present in nature and indispensable to the live of the aquatic animals. This futuristic range of aquariums are designed for a working temperature of 10-30 C and consists of double glass walls in which the two layers of glass are separated by a dry air gap which not only reduces heat and thus energy disperisons but also prevents fogging of the glass when the difference between water temperature and ambient temperature is considerable.They are available with or without integrated refrigerator (chiller) or external climatisator (heater/chiller) and with or without mechanical/biological filter and circulation pump etc. Tables or frames are available as accessoire. Larger isolated holding tanks, on request.

Book Tips:

Hormones and their Receptors in Fish Reproduction
by Philippa Melamed and Nancy Sherwood (Editors), Hardcover, 308 pages (2005).

Research on the molecular aspects of fish reproduction has progressed swiftly over the past few years. With the availability of wide-ranging molecular tools, fish researchers have elucidated many of the molecular mechanisms regulating reproduction which operate in the brain, pituitary and gonad. This research has revealed novel variants of reproductive hormones and their receptors, and has shed new light on the mechanisms through which many of these genes can be activated. Several of the findings, which are reported in this book, have formed the basis for subsequent mammalian research and will also constitute the platform on which new approaches to reproductive management in aquaculture can be developed.

Reproductive Biotechnology in Finfish Aquaculture
by C. S. Lee and E. M. Donaldson, Hardcover, 328 pages (2001).

The successful reproduction of cultured brood stock is essential to the sustainable aquaculture of aquatic organisms. This book describes recent advances in the field of finfish reproductive biotechnology. The chapters in this volume are written by eminent scientists who review the progress and assess the status of biotechnology research that is applicable to the reproduction of finfish species for aquaculture. A wide range of topics is included starting with broodstock technologies such as broodstock genetics, broodstock nutrition, environmental control of maturation and impacts of stress on broodstock, gametes and progeny. The volume includes technologies for induction of ovulation and spermiation using synthetic hypothalamic peptides. Gamete technologies which are described include cryopreservation, chromosome set manipulation, disease prevention and control for gametes and embryos and the development of transgenic fish with enhanced production characteristics. Genetic and endocrine technologies for the production of monosex male and female fish stocks are also described. The closing chapter summarizes the discussion of each topic at the workshop, provides recommendations to industry and describes priorities of research and development. Researchers as well as teaching faculty in the aquaculture field will find this volume of great value.

Artemia Biology
by Robert A. Browne, Patrick Sorgeloos, Clive N. A. Trotman (Editors), Hardcover, 384 pages (1990).

Artemia is widely used in both life-sciences research and aquaculture. Although there are over 4000 references regarding Artemia, the literature is widely scattered. Artemia Biology provides a comprehensive, state-of-the-art review of this literature, containing a considerable amount of previously unpublished data. Although all aspects of Artemia biology are covered, the book emphasizes whole-organism approaches. Topics covered include molecular genetics, ontogeny, clonal diversity, mitochondrial DNA-based phylogeny, and comparisons of Artemia and Parartemia (including a taxonomic key to Parartemia species). The book also contains the latest information on Artemia culturing in fertilized ponds and culture tanks, as well as the use of the organism as a food source. Researchers investigating basic biological questions involving molecular genetics, biochemistry, enzymatic and developmental activities, physiology, ecological genetics and adaptation, ecology, and aquaculture production will find this book indispensable.
