The results of experimental culture for Korean mitten crab, Eriocheir japonicus at different outdoor culture methods such as rice field, pond, and vinyl house from July 21, 1994 to October 23, 1995 were summaried as fellows.
1. The water temperature was 2℃~32℃ during the culture periods from July 21, 1994 to October 23, 1995, and it ranged from 15℃ to 30℃ during the terms showing the intake habit of feed with these temperature maintained for 281 days of 460 days of the total cultur periods.
2. The gain weight of Korean mitten crabs was 1,711.3g at the rice field, and 1,565.4g at the pond, and 1,220.0g at the vinyl house. The survial rate was 22.7% at the pond, and 18.7% at the rice field, and 18.3% at the vinyl house with the average survial rate of 19.9%. The daily growth rate of carapace width was 0.64% at the rice field, and 0.61% at the pond, and 0.59% at the vinyl house. And the gain weight and the daily growth rate were the best at the rice field.
3. When the culture was finished, the frequency of carapace width of 4.0~4.9㎝ was 57.1% at the rice field, and 33.3% at the pond, and 31.2% at the vinyl house. Therefore, culture at the rice field for the cultur of mitten crab was considered to be the best outdoor culture method from the point of view in the fast growth and polyculture feasibility with paddy rice.
