Text in Filipino.The manual discusses tilapia culture methods in concrete tanks, netcages, and fishponds. It details the species of tilapia cultured in the Philippines, which include Oreochromis nilotucus, O.mossambicus, O.aureus. It covers the following: site selection; construction of netcages and its modules; fishpond construction and pond preparation; criteria for fry selection; stocking; netcage and pond management including water quality management; and harvest. The manual also lists the agencies involved in tilapia research and development in the Philippines; defines some technical terms in a glossary, and lists some useful references.3rd Ed

Tilapia culture: The basics

This new aquaculture extension manual revisits the basics of tilapia culture with updated information on the grow-out technology in cages and ponds. Updated cost and returns analyses were also included to guide farmers regarding the profitability of farming tilapia. A fresh chapter on tilapia health management is also included to promote the prevention of tilapia diseases

Growth response of three Oreochromis niloticus strains to feed restriction

Growth of fry from three test strains of Nile tilapia (CLSU, ISRAEL and NIFI) fed restrictively and nonrestrictively were compared. Four-week old fry were matched for size with similarly aged red tilapia fry which served as an internal reference. Fish were stocked in 60l aquaria at a ratio of 25 tests:25 reference fish. Test fish were fed commercial fish feed ad libitum during the initial and final two weeks and rations of the same feed at 10% of the fish biomass during weeks 3 and 4. Control fish were fed commercial fish feed ad libitum throughout the six week experiment. Although feed restriction retarded growth in all three test strains, growth differed significantly between strains. Under both restrictive and nonrestrictive feeding regimes, the ISRAEL strain grew better than the CLSU and NIFI strains

Growth of five Asian red tilapia strains in saline environments

Growth of five Asian red tilapia strains (BFS, NIFI, FAC, PF and HL) were evaluated in brackish and seawater. Eight-week-old juveniles from the five test strains were size-matched with similarly aged Oreochromis mossambicus which served as internal reference. Fish were stocked at a ratio of 15 test:15 reference in 100-l tanks supported by a recirculating system. Commercial feed was given twice daily at 10-20% of the fish biomass. Growth, measured from length and weight increment at 10 weeks, was recorded. Statistical analyses on mean specific growth rates showed significant differences among the strains reared in seawater. The Philippine strain PF grew best in seawater while the Thai strain NIFI performed well in brackishwater. In the Philippines, red tilapias are farmed in intensive freshwater culture systems by few aquaculturists. Results of this study indicate that some Asian strains can be developed for use in more sustainable brackish and seawater culture systems

Salt tolerant Nile tilapia production: Prospects in aquaculture

In the Philippines, salt tolerant Nile tilapia strains have been developed and promoted for culture to increase tilapia production in brackishwater pond systems previously dedicated for milkfish and/or penaeid shrimp culture. This was mainly done to address the decline in the production of such major commodities in ponds and/or cages brought about by diseases and mass fish kills caused by intensified culture methods. The present paper focuses on the different salt tolerant Nile tilapia stocks that have been developed and disseminated in the Philippines, the culture practices involved, as well as the prospects for profitable production of Nile tilapia in saline conditions
