The optimum fish stocking density effected on fish growth performance as a response to growth and survival. Previous research showed that the G5 transgenic mutiara catfish produced 100% (twice) higher growth than non-transgenic catfish in indoor rearing. Further research on G6 at different stocking densities aims to evaluate the growth performance of transgenic mutiara catfish. The study was conducted using a Completely Randomized Design (CRD) with four treatments and three replications on the bucket media. The density treatments used: A (40 fish/60 L), B (50 fish/60 L), C (60 fish/60 L) and D (70 fish/60 L) in the budikdamber (fish farming in buckets) system. The results showed that a density of 70 fish/60 L (treatment D) increased the average biomass weight gain (ABWG) by 2,152 g for 56 days of rearing. In addition, the feed utilization efficiency (FCR) in all treatments of G6 transgenic mutiara catfish did not show any significant differences as compensation for the presence of exogenous GH inserts.
