This research have been done at December, 2013 untill February, 2014. Sampling technique using Proportionate Cluster Random Sampling with fishnet stocking area 12,56 m2. Based on Catch per Unit Effort (CPUE) analyst is known snakehead fish density in Kelubi Lake is 439 fishes. Sex ratio between snakehead fish male and female is 2:1. Population is dominated by widhitebait with level of gonad maturity (TKG) I. Index of gonad maturity is about 0,03-0,94%,
