ABSTRACT
The growth performance of striped murrel, Channa striata larvae which were produced in the pre-monsoon season (April- May) and another in monsoon season (June-August) under controlled conditions has been evaluated with a 30-day experiment. The experiment was conducted for pre-monsoon and monsoon season separately. Two quadruplicate was assigned as T1 (pre-monsoon season i.e., Beyond breeding season) and T2 (spawn produced during monsoon season i.e., breeding season). At the end of the trial, significant (P<0.05) improved weight gain percent, thermal growth coefficient (TGC), survival, and reduced cannibalism were recorded in larvae produced during the pre-monsoon season (T1). From the present study, it is concluded that larvae produced in the pre-monsoon season (T1) could be an additional benefit for the farmers to generate additional revenue in terms of seed production as well as monetary profit.
