Tilapia hatchery and nursery systems: Operation and management Bautista, Antonio M. Guerrero III, Rafael D.; de Guzman, Dalisay L.; Lantican, Cecilia M. The successful and profitable production of Tilapia nilotica in ponds or cages is predominantly influenced by the environment and hereditary traits of the stock. Therefore, stocking of high quality fingerlings is a major requirement to ensure the profitable production of marketable tilapia in 90-120 days. There are reports on crossbreds of F₁ backcross of two strains of T. nilotica stocked in net cages in the central bay of Laguna Lake at 15/m² during the months of May to August, reach a marketable size of 100 to 180 grams in 70 days without supplemental feeding. It is not uncommon for tilapia farmers in Cardona, Tanay and Pililla, Rizal to harvest marketable outbred tilapia after three to four culture months from May to August. In the case of F₃ inbreds of T. nilotica, stocks that have a certain degree of T. mossambica blood, growth is comparatively slower.

Culture studies on Tilapia sp. under saline conditions at the Brackishwater Aquaculture Center Fortes, Romeo D. Guerrero III, Rafael D.; de Guzman, Dalisay L.; Lantican, Cecilia M. This paper reviews the various researches on tilapia at the BAC with the purpose of disseminating the information so far generated and identifying the gaps in tilapia research under saline conditions. Primary studies on tilapia at BAC were concentrated on increasing production of tilapia in brackishwater ponds and how this targetted production could be obtained more effectively and efficiently. Monoculture and polyculture procedures for tilapias including fertilization and feeding were studied. Forage fish: carnivore fish ratios were established for certain species which could be effective in thinning down the population of young tilapia while allowing the original stocks to grow bigger and at the same time producing fingerlings for restocking. This paper presents the results of various studies on tilapia.

Extension and training programs in support of tilapia farming in the Philippines Tayamen, Melchor M. Guerrero III, Rafael D.; de Guzman, Dalisay L.; Lantican, Cecilia M. The Bureau of Fisheries and Aquatic Resources (BFAR), now a staff bureau of the Department of Agriculture (DA), is an agency mandated to look after the national development and management of the fishing industry. It constantly demonstrated its sensitivity towards the attainment of improving the lot of poor fish farmers and fishermen in the countryside. Fisheries, as a major sector of agriculture is expected to push the country s Economic Recovery Program and must be developed to realize its potential contribution. This sector contributed 4.7% at current prices to the Gross National Product (GNP) and 5.0% on constant prices in 1985. The fishing industry directly employs an estimated one million fishfarmers and fishermen. Indirectly, the industry provides employment to household members who are engaged in allied fisheries industries like fish processing, net making, boat building, ice plant and cold storage operation, fish handling, marketing and fish distribution.

Commercial production of tilapia in freshwater ponds and cages in the Philippines Guerrero III, Rafael D. Guerrero III, Rafael D.; de Guzman, Dalisay L.; Lantican, Cecilia M. This paper reviews the state-of-the-art of Nile tilapia production on a commercial scale in Philippine freshwater ponds and cages. Culture practices and problems are also discussed. Commercial production of tilapia as applied here refers to growing of table fish to generate income.
