Abstract: To test the effects of stocking density on growth, survival and production of Thai Sharpunti (Barbonymus gonionotus) an experiment was carried out for a period of 2 months in 9 earthen ponds (each of 2.0 decimal). Three stocking densities were tested: ponds with 100, 200 and 300 fish per decimal designated as treatment T1, T2, T3 each having three replications that were randomly selected. At stocking, all the fishes were same age group having body weight of 2.05g. Fishes in all the experimental ponds were supplemented with Saudi Bangla nursery feed for the first 29 days and starter-1 feed for days of 30 to 64. Water quality parameters were within suitable range for fish culture. At the expiration of trial period, results showed significant differences (P<0.01) including weight gain, percent weight gain, average daily weight gain and specific growth rate among the three treatments (T1, T2 and T3 respectively), indicating the decrease of growth performance with the increasing stocking density, whereas total fish yield were higher with higher stocking density. The survival rate was estimated highest in T1 compared to other two treatments (T2 and T3). Considering the highest net production the stocking density applied in T3 found best, but more research still needed to further optimize stocking density of Thai Sharpunti in aquaculture ponds. Till then, stocking 300 B. gonionotus fish per decimal will yield a better production to fish farmers.
