This study aims at identifying the influence of proteolytic enzymes, papain and bromelin, addition on growth rate and feed utilisation efficiency in gourami fry. Four different concentrations of papain from papaya (0%, 0.75%, 1.5% and 2.25%) and bromelin from pineapple (0%, 1%, 1.5% and 2%) were used. The parameters investigated in this study were: protease enzyme activity, daily growth rate, survival rate, feed efficiency rate and water quality. Papain and bromelin activities were 2.16 and 12.41 units/mg protein, respectively. The addition of papain and bromelin did not affect the growth rate, survival and feed efficiency in a statistically significant way. It is likely that more than 60 days is required to observe the impact of enzyme addition on growth rate and feed efficiency. Thus, more experiments are needed to validate our results.
