An experiment was undertaken in nine experimental ponds to evaluate the impact of stocking densities of Mystus gulio on growth and production of Penaeus monodon, Chelon subviridis and Macrobrachium rosenbergii in polyculture. Three stocking densities of M. gulio were tested with three replications for each, viz., 5000/ha (T1), 10000/ha (T2) and 15000/ha (T3). At the end of culture period, average final weight of P. monodon, M. rosenbergii, M. gulio and C. subviridis in T1 were significantly higher (P<0.05) than those in T2 and T3. Survival of P. monodon (64.9 %), M. rosenbergii (65.5 %) and C. subviridis (71.5 %) was highest in T2 whereas, survival of M. gulio (73.7%) was highest in T1 than other treatments. Among the treatments, significantly (P<0.05) highest total production obtained in T2 (1352.1 kg/ha), followed by T3 (1078.5 kg/ha) and T1 (955.2 kg/ha) in 150 days. Therefore, among all treatments, 10,000/ha stocking density of M. gulio would be the best recommendation for the poly culture with P. monodon, M. rosenbergii and C. subviridis.
