Abstract

 Clarias batrachus (Linnaeus, 1758) larvae were subjected to different modes of probiotic (Bacillus subtilis) administration such as:  T1: feeding Artemia nauplii enriched with B. subtilis; T2: feeding enriched Artemia nauplii + addition of B. subtilis in water  and T3: addition of B. subtilis in water alone, for a period of 14 days. A control group (T0) with no probiotic administration was also maintained. On termination of the experiment, probiotic supplemented through enriched Artemia nauplii along with addition in  water (T2) yielded significantly (p<0.05) higher length,  weight, weight gain, specific growth rate and survival compared to control (T0) and T3 groups. All these parameters did not differ significantly (p>0.05) between T1 and T2. Similar trend was observed in the case of total gut bacterial count and digestive enzyme activity. The highest (p<0.05) digestive enzyme activity of protease, lipase and amylase   were recorded in T2, while no significant (p>0.05) difference was observed between T2 and T1. The present study reiterated the advantage of B. subtilis, and its administration through enriched Artemia nauplii which could be a promising supplementation mode during   C. batrachus larval rearing.
