Aquaculture: Applied Genetics of Tilapias; Summary Report of the ICLARM Conference on the Biology and Culture of Tilapias; and the ICLARM-CLSU Integrated Animal-Fish Farming Project - Poultry-Fish and Pig-Fish Trials

摘要

The book consists of four reports. The first covers the geographical distribution of Tilapias; Variation between Species; Interspecific Hybridization; Sex Determination; Variation within Species. The second is a summary report of the ICLARM Conference on the Biology and culture of Tilapias held in Bellagio, Italy, 2-5 September, 1980. It contains sections on Biology, Physiology, and Culture; and a consensus statement and research requirements. The third describes fish production trials in conjunction with pigs and ducks using 40 or 60 pigs/ha and 750 or 1250 ducks/ha of pond surface, with total fish stocking densities of 10,000 or 20,000/ha. The highest net yields were obtained with the 60 pig/20,000 fish and 750 ducks/20,000 fish combinations. Based on the estimated production functions relating fish yield to manure input, optimum manure loading rates were computed for Philippine pig-fish operations at prevailing market prices.
