THE IN­TRO­DUCED TILAPIA is the sec­ond most im­por­tant farmed or cul­tured fish in the coun­try next to our na­tive milk­fish. In 2016, we pro­duced 300,720 met­ric tons (MT) of tilapia (mainly the Nile tilapia) from farms (86%) and fish­ing from in­land wa­ters (14%) with a value of R24 bil­lion. Our pro­duc­tion of farmed tilapia in 2015 was 260,966 MT with 54% com­ing from fresh­wa­ter ponds, 30% from fresh­wa­ter cages, 8% from fresh­wa­ter pens and 7% from brack­ish­wa­ter ponds. Most of the farmed tilapia pro­duc­tion was from Lu­zon (92%), with Min­danao and the Visayas con­tribut­ing only 6% and 2%, re­spec­tively. Lu­zon (69%) and Min­danao (31%) were in­ter­viewed through fo­cus group dis­cus­sions and key in­for­mants. Of the 55 re­spon­dents, 38 or 72% said that their tilapia pro­duc­tion de­creased by 52.4% on the av­er­age in the last five years. So­cioe­co­nomic, tech­no­log­i­cal, in­sti­tu­tional, and cli­matic fac­tors that could cause the de­cline in farmed tilapia pro­duc­tion were pre­sented in a struc­tured ques­tion­naire. The ma­jor fac­tors iden­ti­fied by the farm­ers were “High Wa­ter Tem­per­a­ture” (68%), “Lack of Gov­ern­ment As­sis­tance” (58%), “Poor Breed of Tilapia” (48%) “High Cost of Pro­duc­tion” (46%), and “Lack of Cap­i­tal” (44%).

From the AAPRs of the var­i­ous tilapia cul­ture sys­tems, the study con­cluded that brack­ish­wa­ter
