Or­ganic ti­lapia grow­ing fea­si­ble in Re­gion 2

Manila Times - - Regions - LEANDER C. DOMINGO

TUGUEGARAO CITY, Ca­gayan: With­out the need for ex­pen­sive com­mer­cial feeds and other in­puts, fish­er­men in Ca­gayan Val­ley (Re­gion 2) said there is noth­ing more to worry about chem­i­cal

The Bu­reau of Fish­eries and Aquatic Re­sources ( BFAR) in Re­gion 2 has shown vi­a­bil­ity of Imelda Ban­gloy in Gamu town in Is­abela prov­ince.

Rho­damel So­ri­ano, Or­ganic Ti­lapia project leader, said a total of 348 ki­los was har­vested af­ter six months in the demon­stra­tion farm, with har­vests av­er­ag­ing 200 grams.

So­ri­ano added that farm­ers could fol­low the pro­to­col on or­ganic ti­lapia farm­ing in this demo farm where chem­i­cal-free pond prepa­ra­tion was made, fol­lowed by fer­til­iza­tion.

“Fer­til­izer used was ver­mi­cast ap­plied at rate of 1,000 to 2,000 kilo­grams per hectare per month,” she said.

Ban­gloy’s pond mea­sures 1,500 square me­ters and was stocked with 4,500 ti­lapia at - lings per square me­ter.

So­ri­ano said this was lower com­pared to the five pieces - om­mended for semi-in­ten­sive cul­ture of ti­lapia .

The lower stock­ing den­sity, ac­cord­ing to her, aims to max­i­mize uti­liza­tion of nat­u­ral food, which is made avail­able with ap­pli­ca­tion of or­ganic fer­til­izer reap­plied ev­ery month us­ing the same rate.

“Feed­ing rate was com­puted at 10 per­cent dur­ing the first month and grad­u­ally re­duced to 2 per­cent to­ward the end of the six-month cul­ture pe­riod,” So­ri­ano said.

She added that in­stead of com­mer­cial fish feeds, the demon­stra­tion farm uti­lized a spe­cially for­mu­lated or­ganic meal, 30 per­cent co­pra meal, 20 per­cent D1 darak (bran) and

Other feeds uti­lized were duck­weeds and wa­ter spinach (kangkong).

“Or­ganic farm­ing pro­motes farm- made feeds us­ing avail­able lo­cal raw ma­te­ri­als,” So­ri­ano said, ad­ding that yield might be lower in or­ganic ti­lapia com­pared to the usual semi- in­ten­sive cul­ture ( with com­mer­cial feeds) but cap­i­tal­iza­tion was also much lower.

She said sale from this project was P38,300 with net in­come of P13,047 and, ac­cord­ing to her, in­come could be much higher as the pro­duce could be priced higher since it was or­ganic.

Ac­cord­ing to BFAR, the project is pur­suant to Repub­lic Act 10068 or “An Act Pro­vid­ing for the Devel­op­ment and Pro­mo­tion of Or­ganic Agri­cul­ture in the Philip­pines.”
