- Genetic improvement of farmed tilapias: Biochemical characterization of strain differences in Nile tilapiaMacaranas, Julie M.; Agustin, Liza Q.; Ablan, Ma. Carmen A.; Pante, Ma. Josefa R.; Fukushima, A.; Pullin, Roger S. V. (Springer, 1995-03)Four African wild strains (Egypt, Ghana, Senegal and Kenya) and four established Asian farmed strains of Nile tilapia, Oreochromis niloticus (popularly known in the Philippines as ‘Taiwan’, ‘Thailand’, ‘Singapore’ and ‘Israel’) were analysed electrophoretically at 30 protein loci to estimate genetic differences among the strains. All strains shared alleles at 14 monomorphic and 16 variable loci. Among the African strains, characteristic allele frequency differences were observed at AAT-1 * 46 for Ghana and Senegal, ADH * 83 for Kenya, ADH * 120 for Senegal, G3PDH-2 * 300 for Egypt, IDDH * 67 for Senegal, sMDH-1 * 120 for Kenya and SOD * 150 for Senegal. Genetic distance values among the strains revealed a clustering of the farmed strains with Egypt and Ghana O. niloticus, a slight separation of the Senegal strain and a larger separation of the Kenya strain. This profile may reflect the origins of the few founder populations of this species previously introduced to Asia. It also confirms the wider genetic divergence of the Kenya strain (O. niloticus vulcani) from the others studied here, which are all O. n. niloticus. Observed heterozygosities of the strains ranged from 0.026 to 0.071, with the African wild strains the lower values (mean Ho = 0.036) and the farmed strains the higher ones (mean Ho = 0.056). The implications of these results to the ongoing tilapia genetic improvement programme in the Philippines are discussed.
- BFAR, Itbayat Island open first tilapia hatchery(Philippine Manila Standard Publishing, Inc., 2024-04-11)Batanes fish farmers will soon have their own local source of tilapia fingerlings as the Department of Agriculture-Bureau of Fisheries and Aquatic Resources (DA-BFAR) and the local government inaugurated on April 4, 2024 the province’s first municipal tilapia hatchery in Barangay Raele in the island municipality of Itbayat. The facility, equipped with breeding, nursery, treatment and conditioning ponds and a water system vital for hatchery operation, is expected to produce 300,000 to 500,000 pieces of tilapia fingerlings annually.
- BFAR opens Laguna tilapia intensive hatcheryMiraflor, Madelaine B. (Manila Bulletin Publishing Corporation, 2021-09-02)The Department of Agriculture’s (DA) Bureau of Fisheries and Aquatic Resources (BFAR) has successfully conducted the first trial run of its second tilapia intensive hatchery in the CALABARZON region, a development that will help boost the productivity of tilapia farmers. Located in Los Baños, Laguna, the hatchery recorded a high hatching rate of 95 percent, which means a high number also of fry produced. At present, the hatchery has six fry trough and hatching jars, and can produce 300,000 fry in just three to five days. Following the successful trial run, the hatchery now aims to complete four rounds of hatching per month, BFAR said.
- BFAR to distribute milkfish fingerlings in La UnionGarcia, William Jun (The Manila Times Publishing Corporation, 2014-10-09)Mayor Pablo Ortega on Tuesday led the distribution of rehabilitation milkfish fingerlings to fishermen from six villages whose fishponds dried up due to April’s intense summer heat. The milkfish fingerlings came from the Bureau of Fisheries and Aquatic Resources, which will also distribute tilapia fingerlings to upland villages next year. Dolores Gurtiza, fishery chief of the City Agriculture Office, said San Fernando received the highest total of rehabilitation fingerlings with 64,020.
- Lake Sebu fish kill destroys ₱20M worth of tilapiaSarmiento, Bong S. (Philippine Daily Inquirer, Inc., 2021-01-13)At least 1,000 fish cages containing about 200,000 kilograms of tilapia were ravaged by the latest fish kill in Lake Sebu town, South Cotabato province, last week, an official said on Monday. Lake Sebu Mayor Floro Gandam said at least 250 tilapia growers would get aid from the local government to recover their losses estimated at P20 million.But officials who joined an emergency meeting which Gandam convened on Monday did not think the damage was extensive enough to place the town under a state of calamity. Christopher Ofong, the municipal information officer, said the disaster risk reduction and management office decided against recommending the declaration of state of calamity because some criteria were not met, such as the condition that the fish kill should affect at least 20 percent of the population.
- BFAR 7 Bohol farm nets high tilapia production(Sun • Star Publishing, 2020-10-11)The Bureau of Fisheries and Aquatic Resources (Bfar) 7 and its Clarin Freshwater Fish Farm (CFFF) in Clarin, Bohol have exceeded their target for tilapia production for 2020. Gaymelo Lopez of CFFF said the field facility reached its annual target of producing six million tilapia fry or fingerlings by the end of September. As of Oct. 28, Lopez said, the tilapia production had reached 7.5 million. The production number is still increasing, he said in a report posted on Bfar 7’s Facebook page.
- ₱12.3-M tilapia lost in Taal Lake fish kill: BFAR monitoring waters off 3 lakeshore townsCinco, Maricar (Philippine Daily Inquirer, Inc., 2019-06-01)At least 150 tons or P12.3 million worth of cultured tilapia turned belly-up in fish cages in Taal Lake in Batangas province due to a low level of dissolved oxygen in the water. The Department of Environment and Natural Resources and the local government of Laurel town in Batangas continued to closely monitor the remaining fish cages after the fish kill occurred in the villages of Gulod and Buso-buso in the last two days. As of Friday, provincial environment officer, Jose Elmer Bascos, said they had yet to dispose all of the dead fish as they needed a larger area to bury them.
- Taal fish feeding resumes as water quality improvesSimeon, Louise Maureen (Philippine Star Printing Co., Inc., 2019-02-09)Fish cage operators can now resume feeding their fish stocks in Taal Lake after tests showed improvements in the quality of water. Agriculture Secretary William Dar said tests conducted by the Bureau of Fisheries and Aquatic Resources (BFAR) from Jan. 14 to 30 revealed that the level of dissolved oxygen in Taal Lake, which is essential to fish growth and survival, had already improved. BFAR Calabarzon director Sammy Malvas said Taal water quality tests also showed that the sulfide level is within normal.
- Pangasinan aquaculture practices wow US studentsVisperas, Eva (Philippine Star Printing Co., Inc., 2019-02-06)Students of the University of Rhode Island arrived in Pangasinan on New Year’s eve for their 20-day study of the best aquaculture practices in various coastal areas of the province and got wowed. From going to the rivers, the 10 students led by their professor Michael Rice experienced demonstration and did hands-on sex determination/cannulation of milkfish breeders and feed preparation/enrichment at the Philippine Bangus Center, seining milkfish broodstock from a maturation pond at the Bureau of Fisheries and Aquatic Resources center, all in this city. At the BFAR center, the students also had the opportunity to harvet bangus and saltwater tilapia from ponds.
- BFAR-6 to spend P10M for fingerling dispersal project(Panay News, Inc., 2017-01-05)The Bureau of Fisheries and Aquatic Resources (BFAR) will spend around P10 million for its free fingerling dispersal project in Western Visayas this year. In an interview Tuesday, BFAR-6 director Remia A. Apari said the fingerling dispersal is their contribution to achieve the mandate of the Department of Agriculture (DA) to provide affordable and available food on the table of every Filipino. Tilapia fingerlings will be released to coastal and upland areas and are expected to benefit some 100 fisher folks. Initially, “hito” or catfish juveniles will be provided to some 60 to 60 fisherfolk. The fingerlings will come with the corresponding feeds requirement, which will also be provided free, she said.
