Snakeskin gourami is a potential local fish in Indonesia. Up to present, the major production came from natural catch. These conditions tend to decrease rapidly the natural stock. Domestication offers the promising solution of this problem. Three snakeskin gourami populations from Lampung, East Java and West Kalimantan were used as potential genetic source considered for culture. These snakeskin gourami populations showed the best genetic diversity from Sumatra, Java and Borneo. This study aimed to investigate the potencies of snakeskin gourami from Lampung, East Java and West Kalimantan as fish culture candidate based on truss morphometric and growth performance.

Morphometric comparison test indicated 5 distinguish characters between Lampung, East Java and West Kalimantan populations. These were A3 (upper mouth - upper operculum), A5 (upper operculum - low operculum), B5 (early dorsal fin - ventral fins), C4 (end of the dorsal fin - end of the anal fin) and C6 (early dorsal fin - the end of the anal fin). The canonical function illustration showed that morphometric characters from three populations distributed in different quadrants. On the negative X-axis, East Java population was distinguished to Lampung and West Kalimantan (Figure 1). The highest intra population sharing value gained by East Java population (66.7%) and lowest in Lampung population (43.3%). While the highest inter population sharing gained between West Kalimantan and Lampung population (50%).

Lampung population showed the highest growth length (1.8±0.04) and significantly differences compared with East Java and West Kalimantan population. Lampung showed the highest specific growth rate (1.86±0.02%) and significantly differences between populations. Seed survival rate ranges between 93,3 - 94,4% (Tabel 1).
