Abstract: Microbiological survey in the Luozhou River and a pond of Doumen County Guangdong Porvina from March to July in 2001 provided the data for study in the variations of heterotrophic bacteria and vibrio population size with some environmental factors. The results showed that heterotrophic bacteria and vibrio population densities in Luozhou River and pond increased with water temperature. But when COD increased, these densities in the pond appeard to decline. The popula tion densities of heterotrophic bacteria in Luozhou River and pond ranged from 200cells穖l-1 to 9.7?104cells穖l-1,and those of vibrio ranged from 800 cells穖l-1 to 1.97?104cells穖l-1.

Key words: super-cooling point, water content, total fat content, total protein content, total glycogen content, Carposina sasakii.
