Tilapia can now be grown for export fillet market – BFAR-10
Cagayan de Oro City (25 September) -- Before, the harvest size of tilapia was on the average of 350 grams, but now it can reach up to 600-800 grams, the desired size of tilapia for fillet especially for the export market.
Growing bigger tilapia for export fillet market was among the technologies presented in the 2007 Mindanao Cluster Regional Technology Forum and Product Exhibition/Fair in Grand Caprice Restaurant, Cagayan de Oro City. The technology was locally verified by the Regional Fisheries Research and Development Center of the Bureau of Fisheries and Aquatic Resources-10.
Though the purpose of growing bigger tilapia is for export fillet market, it can also be applied to the production of tilapia for local markets sold as whole or frozen. Bigger-size tilapia commands higher price even in local markets.
To grow tilapia for export fillet market, one must use the GET EXCEL strain of tilapia which is available at Kisolon Freshwater Fish Production and Regional Training Center in Sumilao, Bukidnon and in BFAR-10 accredited satellite-hatcheries. The 50 gram-size GET EXCEL tilapia fingerling is preferred during stocking for faster growth and high survival rate.
The ponds are weekly fertilized at a rate of 28 kgs. Nitrogen and 7 kgs. Potassium for every hectare. Conducting weekly fertilization enhances the growth of natural food and lessens the use of commercial feeds. Tilapia is herbivore so even if it is fed with commercial food, natural food like plants and algae still play a major role in its growth.
The stock is fed at satiation level in the first day of each week, wherein the feeds for the rest of the week are weekly determined.
After three months, the stocks are to be manually segregated to male and female. The female are harvested while the male will continue through the culture period until six to eight months depending on demand. Male tilapia grows 40% faster than the female tilapia. The average body weight in the final harvest is 650 grams.
This technology process allows the fishfarmer to have two harvests in a single cropping which can supply both local and export market needs. (BFAR-10) [top]
