Abstract
The objective of this study was to study the efficiency of relative humidity control system for the nursing of tadpole (Hoplobatrachus rugulosus). The research methods were divided into 2 steps;
1) designing the relative humidity control for the tadpole nursing and 2) comparing the efficiency tadpole nursing system between relative humidity control and traditional system. Natural environmental structures including air temperature, light intensity, water temperature and relative humidity and tadpole’s growth indicators including weight, length and survival rate were collected. The result showed that relative humidity in control system was 88.72 throughtout 30 days of experimental time. Weight and length of tadpole in the relative humidity control system was higher than the traditional system significant difference (p<0.05) at 52.73±6.54, 27.72±2.09 grams and 8.76±0.39, 8.05±0.34 centimeter respectively. The survival rate of tadpole in the relative humidity control and traditional system were 70.3 and 62%, respectively.
