Milkfish has grown to be one of the most important aquaculture species in the country. It is widely grown in 7 out of the 16 regions of the country, majority of which are in Central Luzon, Northwestern Luzon, and Western Visayas.
In the Philippine setting, milkfish aquaculture has
expanded from the traditional culture in brackish water ponds and freshwater pens to marine cages and pens. It has also evolved from extensive (low stocking density, no supplemental feeding) to intensive (high stocking density with supplemental feeding) culture.
Fry, one of the farming methods being raised in either sea cages, large saline ponds is mainly done using natural environmental cues. However, there
have been attempts using gonadotropin-releasing hormone analogue (GnRH-A) to induce spawning. Some still use the traditional wild stock method; and this involves capturing wild fry using nets.
Since 1993, the back-yard hatcheries have functioned as successful production centers of milkfish fry. The fledgling industry received a substantial boost in 1998 due to profits from increased milkfish prices. The subsequent hatchery investment boom resulted in a pyramid of job opportunities that expanded the horizons and incomes of the local people, and also attracted an estimated 5,000 workers nationwide.
Among the new job titles were hatchery construc
tion worker, technician, fry counter, fish packer, and broker, marketer, trader, and product exporter. Compensation for workers is usually 20% of the sale price, and incomes vary with the price of the product. About 40-50 new, larger hatcheries now produce and sell surplus fertilized eggs to smaller back-yard hatcheries. Presently, local people own approximately 10% of these larger hatcheries.
This industry has strengthened the area and its economy. It embodies the power of combining technology, local enterprise, and sustainable use of natural resources. It increases the options to the milkfish farmers in terms of modification and improvements in production systems, feed formulation, brood stock management and hatchery technology. This could be the start of something great for the country; more jobs, more opportunity.
