Abstract
In the present investigation, herb, Bala was used growth promoter with the supplementary feed of an Indian major carp, Cirrhinus mrigala (Ham.). Basal diet of fish comprised of groundnut oil cake and rice bran in 1:1 ratio. The fingerlings of Cirrhinus mrigala (Ham.) were reared for 60 days (excluding initial 5 days of acclimatization period) in the glass aquaria having 36 litres of water. During this experiment, the fingerlings of mrigal were fed with four experimental diets. Growth parameters such as weight gain, FCR, GCE, SGR etc. were also monitored to assess the use of this herb as growth promoter. After 60 days of experimental period, proximate composition of fingerlings reared in these aquaria was also determined for observing the effect of herb on the biochemical profile of experimental fish.
Bala was mixed with the supplementary diet of fish at four different levels viz., 0.06, 0.10, 0.14 and 0.18 gm/kg body wt/day. The fingerlings fed with diet B3 containing Bala @ 0.14 gm/kg body wt/day performed better growth interms of weight gain to the extent of 26.50%, whereas, fish reared on control diet exhibited weight gain of 12.22% only. The growth per day in per cent body weight, FCR, GCE and SGR were also superior with B3 diet. Further, fingerlings fed with this diet showed significant change in the proximate composition compared to the control. Based on this experiment following ranking can be made for relative performance of various doses tried:
B3 > B4 > B2 > B1 > C (control)
(0.14) (0.18) (0.10) (0.06) (No herb)
This preliminary screening of Bala herb tried for the first time on mrigal suggests for undertaking further trails under field conditions taking different parameters and other fish species for experimentation.
