Abstract

In this experiment, the roots of a herb mulethi (Glycyrrhiza glabra Linn.) were mixed with the supplementary diet (groundnut oil cake and rice bran in 1:1) of fish at three different levels and fed to the fingerlings of an Indian major carp Cirrhinus mrigala (Ham.) in the glass aquaria. Mulethi was mixed with the conventional diet @ 0.1% (T₁), 0.2% (T₂) and 0.3% (T₃) and control diet was kept without mulethi. Experimental diets including control were fed @ 2 per cent body wt. of fish per day for 60 days. The fingerlings fed with diet T₃ (containing mulethi @ 0.3%) gave the highest growth (weight gain) of 24% where as fingerlings fed with diet T₁, T₂and C (control) diets showed the weight gain of 18.52%, 20.37% and 12.77%, respectively. Analysis of variance indicated that the growth per day in per cent body weight, average wt. gain, food conversion ratio (FCR), gross conversion efficiency (GCE) and specific growth rate (SGR) were significantly higher (P<0.05) in all the three treatments as compared to control.
