JICA Tilapia ( Tilapia sp.) is one of the tilapia strain that originally from Japan. This species is main commodity of Jambi Freshwater Aquaculture Development Centre (JFADC) ( Balai Perikanan Budidaya Air Tawar Jambi-BPBATJ). It was chosen because of its good adaptability in acid or swamp waters and fairly good growth. Some problems arose in its development efforts , especially fish diseases problem. Until now, Streptococcus infection is serious disease for tilapia, causing economic losses. Prioritized control efforts by vaccination to prevent disease and reduce mortality. In general, most effective vaccine from similarly isolate or close with bacteria pathogen, in this case local isolates.
C hallenge test with pathogen injection to observe vaccination impact on JICA tilapia. Isolates choice for vaccine acquired from disease monitoring in BPBAT working area. Vaccinated fish are kept at small scale hatchery (UPR) to establish broodstock production cooperation . SWOT (Strength, Weakness, Opportunity, and Threats) analysis conducted on UPR respondent to understand main factors influence vaccinated fish. Afterwards to determine development strategy for sustainability uses SWOT-AHP analysis (combination of hierarchical analysis (AHP) and SWOT analysis).
Post challenge result for vaccinated fish, survival rate (SR) 76,67 % and relative percent survival (RPS) 71,07 %. T his result is similar as the result at UPR. In farm 90-days production period, survival rate of JICA vaccine is 69,92% , which differs significantly with non-vaccinated fish (SR 45,66%). Therefore, vaccine significantly reduced fish mortality. SWOT analysis result shows that internal factor for succeedss production at UPR is strength factor i.e., quality of JICA Tilapia parents’ stock and resistance from disease. Meanwhile, greatest external factor impact is opportunity i.e., several UPR are capable of producing JICA tilapia brood stock according standards. Furthermore, chosen main strategy for future development is SO (Strength-Opportunity) strategy, which is increase production for vaccinated fish and maintaining fish quality (priority of importance 42,82 %).
