changes and can optimize high stocking densities (SD). The purpose of this study was to
determine the effect of nursery culture in high stocking density with RAS on survival rate
(SR), specific growth rate (SGR), relative length (LR), weight gain (WG), length gain (LG)
and feed utility efficiency (FUE) of juvenile catfish. The study used a completely randomized
design with 4 treatments and 3 replications: R3000 (SD of 3,000 fish/m 2 with RAS); NR3000 …
