Assessment the impact of 17'-Methyl testosterone on the growth and survival rate of golden barb fish, Puntius gelius (Hamilton, 1822).

摘要

The present study was conducted to assess the impact of an androgenic hormone, 17 a methyl testosterone (MT) on comparative growth promoting efficiency in Golden Barb, Puntius gelius. The hormone incorporated feed was fed to the fish through pelleted diets at three concentrations: 5, 15 and 25 ppm kg dietG1 in addition to a fourth control group without hormone. From the results obtained it is clear that the hormone MT has promoted the growth rate to a significant level (P<0.05) over the control. While the 25 ppm concentration recorded a maximum specific growth rate (1.83+or-0.1 ppm/d) a forceful reduction in the growth rate (0.52+or-0.64 ppm/d) was observed at 5 ppm level. The survival rate was not affected by different dosages of this hormone.
