Abstract
The effect of water temperature on sex ratio of guppy (Poecilia reticulate) was investigated. Treatments of 26, 28, 30, 32°C and control (normal temperature) were used on gravid female and rearing of hatchlings. The highest temperature treatment (32°C) caused the death of gravid females. In this experiment, female offspring production was found increased with decreasing temperature. As such the highest (66.67%) females were observed in control. Whereas the highest male (63.33%) were noticed in 30 0C treatment. Generally, sex ratio biased to male and female at high and low temperature treatments respectively
