Saline Tilapia: A beneficial partner in prawn rearing

It was more than a decade ago when Northern Mindanao’s prawn industry was almost crippled by Vibriosis, a luminous bacterial disease that caused sudden drops in the region’s shrimp production. The destruction caused by this event greatly affected the region’s shrimp producers prompting some intensive farms to close down, while extensive farms which contribute 88% of the region’s shrimps also suffered huge monetary losses.

In Region 10, Misamis Occidental alone has devoted 1,790 hectares of its total brackishwater fishpond area to prawn farming. Of this area, 95% are comprised of extensive farms which are characterized by low stocking densities of about 5 pcs /sq meter and below. These extensive farms are greatly preferred in this region since it is relatively cheaper to maintain but almost always produces high quality shrimp products because of less disease occurrences and problems. Likewise, extensive farming is more environment-friendly since it utilizes naturally available food organisms thus limiting the input of feeds and chemical supplements.

Ulang Production / Freshwater shrimp culture

Ulang Production / Freshwater shrimp culture

Ulang production is an alternative for tiger prawn culture. Ulang is grown in freshwater which is a great advantage for those who are living in low lands or living near lake areas.

Marlo Pagulayan an ulang grower in Cagayan said that for an investment of 21,000 pesos you could earn an aroudn 10,000 pesos. THis is almost 50% return in investment.

What make ulang special is that you can feed it with indigenous feed stuff. As to Mr. Pagulayan’s experience, he fed his Ulang with boiled crush suso which is a pest from his rice field. He also feed it with ripe papaya, grated coconut, and other vegetable like squash and carrot. Cultue period would take around 5 months.

Another advantage of ulang is that you could put tilapia also in the same pond / polyculture technology.
