Impairment induced due to chloramphenicol and ginger on growth parameters of Channa punctatus (Bloch)
Abstract
A maiden study was aimed to comparatively investigate the results of chloramphenicol and ginger on certain growth parameters of Channa punctatus (Bloch). The 96hr-LC50 tests have been carried out along with a control group. Data were analyzed using regression analysis to determine 96hr-LC50 values. The mean values for chloramphenicol and ginger were calculated 55.0 mg l-1 and 52.0 g kg-1 respectively. Phytochemical components of ginger were analyzed. Channa punctatus (57.5±2.0 g and 19.0±1.0 cm) were assigned to seven treatments with three replicates each. Fish had been fed twice daily with commercial feed at 5% body weight for 60 days. The samples have been investigated for various growth parameters such as final weight (FW), Weight gain (WG), daily weight gain (DWG), specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency ratio (FER) and survival rate (SR). Most of growth parameters (FW, WG, DWG, SGR and FER) had been found increased even as FCR reduced than the normal. ANOVA inferred that 2.60g/kg ginger adjust the growth parameters more profoundly than 2.75mg/l chloramphenicol. Although, the mean values of growth parameters except FCR inferred their decline in chloramphenicol but elevation in ginger treated groups as compared to control. The statistical evaluation revealed a significant distinction between chloramphenicol and ginger treatments. The results indicated the chloramphenicol is harmful for fish health. Therefore, ginger may be without difficulty used in vicinity of chloramphenicol.
