Book Description
ABSTRACTImproving the efficiency of production, profitability and nutrient utilization are the most important factors for aquaculture companies. Many research efforts have been focused to develop strategies that improve the productive performance of shrimp farms. One recognized strategy is polyculture, which can considerably improve farm production yields by optimizing use of available resources. Tilapia production in shrimp ponds (with and without shrimp) has increased rapidly in many countries including Thailand, the Philippines, Honduras, Mexico, Peru, and the inland desert of Arizona. A current practice in extensive, semi-intensive and intensive culture systems is the integration of tilapia with shrimp to increase total productivity. I tested this hypothesis in the present trials experimentally by co-cultivating tilapia and Pacific white shrimp in closed recirculating systems. The present series of experiments were carried out over a period of three years between 2007 and 2009. All of these studies were developed and conducted at the facilities of the Environmental Research Lab (ERL) of the University of Arizona in Tucson, AZ. A preliminary study included three treatments in low salinity water (5 ppt). White shrimp post larvae were stocked into cylindrical plastic pools and Red tilapias were stocked into aquaria. Equal numbers of shrimp were placed in all the treatments whereas fish (Red tilapia) density was variable. We found good growth and 100 % survival of shrimp and tilapia. The first experiment included five treatments with four replicates each with saline water of 10 ppt. Shrimp and Nile tilapia were weighed and distributed in 20 fiberglass tanks with capacity of 200 liters. There were evaluated finding statistically significant differences in growth of tilapia (P0.05) but no significant difference in growth of shrimp at different fish densities (P0.05)The second and third experiments included four treatments with four replicates each using the same shrimp density in each study but different fish density by treatment. Results of one-way analysis of variance (ANOVA) for the second experiment showed a significant effect of the shrimp- tilapia polyculture on the growth of Pacific white shrimp (P0.05) but not for tilapia (P0.05) compared with monoculture. In the third experiment, there were significant differences in the growth of shrimp (P0.05) but not significant differences in the growth of fish (P0.05). These experiments were conducted using slightly different culture systems.

Book Description
Intensive tilapia co-culture is the commercial production of various species of tilapia in conjunction with one or more other marketable species. Tilapia are attractive as a co-cultured fish because of their potential to improve water quality, especially in penaeid shrimp ponds, by consuming plankton and detritus and by altering pathogenic bacterial populations while increasing marketable production. Following introductory chapters covering ecological aspects of co-culture, tilapia feeding habits, historical use, and new models, Tilapia in Intensive Co-Culture is divided into co-culture in freshwater and marine environments. Co-culture core information is presented on Vibrio control, high-rate aquaculture processes, aquaponics, tilapia nutrient profile, and tilapia niche economics and marketing in the U.S, and with carp, catfish, freshwater and marine shrimp in the Americas, the Middle East, and Asia. Tilapia in Intensive Co-Culture is the latest book in the prestigious World Aquaculture Society (WAS) Series, published for WAS by Wiley Blackwell. It will be of great use and interest to researchers, producers, investors and policy makers considering tilapia co-culture in terms of environmental and economic sustainability.

Book Description
Master's Thesis from the year 2012 in the subject Biology - Zoology, grade: B, Norwegian University of Science and Technology (Animal Science - Norwegian University of Life Sciences), course: Aquaculture - Tilapia, language: English, abstract: This literature review has been written to examine different tilapia farming practises both in semi-intensive and extensive systems. Extensive culture is not mentioned sine it is not considered to be a real commercial production as the control over the system is quite limited and even semi-intensive system is being replaced by intensive system due to technological developments, high demand and increasing market prices of tilapa. In first chapter, environmental and nutritional requirements are also mentioned as they are closely correlated play a key role in a succesful production. The results of some recent studies and experiments suggest that tilapia has some superiority over other culture fish like faster growth, ability to utilize different feeds, wide tolerance for high stocking densities and environmental conditions. In addition to these advantages, tilapia do very well in integrated culture systemsboth with aquatic species; carp and shrimps, also crops like tomato and lettuce as well. As a result this study is conducted to prove the advantages of commercialtilapia production covering economic values.

Book Description
Mapping of animal genomes has generated huge databases and several new concepts and strategies, which are useful to elucidate origin, evolution and phylogeny. Genetic and physical maps of genomes further provide precise details on chromosomal location, function, expression and regulation of academically and economically important genes. The series Genome Mapping and Genomics in Animals provides comprehensive and up-to-date reviews on genomic research on a large variety of selected animal systems, contributed by leading scientists from around the world. This volume summarizes the first era of genomic studies of aquaculture species, in which the tools and resources necessary to support whole-genome sequencing were developed. These tools will enhance efforts toward selective breeding of aquaculture species. Included in this volume are summaries of work on salmonids, cyprinids, catfish, tilapias, European sea bass, Japanese flounder, shrimps and oysters.
