Abstract: The present investigation was carried out in winter season to investigate the effect of different temperature ranges on the caudal fin regeneration of Flying Barb Esomus danricus in glass aquariums (30.0 x 15.0 x 15.0 cm). Hence the fishes were reared at three different temperature treatments viz. 22±1°C (T22), 26±1°C (T26), 30±1°C (T30) with three replications of each treatment for 30 days under laboratory condition. Fishes were fed twice daily with mixed zooplankton upto adlibitum. Ten numbers of fish species (n=10, Mean caudal fin length=5.240±0.274mm) were stocked into each glass aquariums following a completely randomized design (CRD) after the amputation of the caudal fin using sterilised scissor. Here the temperature was maintained by using thermostats and aeration was provided. At the end of the study, the higher temperature (T30) treatment group shown the highest (P < 0.05) total mean caudal fin length followed by T26 treatment group compared to lower temperature (T22) treatment group. The length increment (mm) gain and percent weight gain was found significantly (P < 0.05) higher in T30 and T26 treatment group compared with T22 treatment group. It has also observed that there was no mortality during the experimental periods. The results indicated that that high temperature has an overall stimulating impact on the structural recovery caudal fin of Esomus danricus may help to consider the fish as model fish for genetics, biotechnology and biomedical studies.
