보통옆새우(Gammarus sobaegensis : 옆새우과, 단각목)의 서로 다른 배양액 및 온도에 대한 생존율

Abstract

Gammarus sobaegensis, a common amphipod crustacean in Korean mountain streams, was experimented in the laboratory in terms of two environmental factors, medium and temperature conditions, which are essential in laboratory rearing. Individuals of G. sobaegensis were collected from a small spring outlet beside Gapyeong stream in Gyeonggi-do, Korea, in December 2003. Survivorships of G. sobaegensis were evaluated from the effect on rearing media (distilled water: DW, tap water: TW, chironomid rearing medium: CM, and stream water: SW) and temperatures (10, 15, 20, and 25℃). As a result, G. sobaegensis was higher in survivorships at TW followed by SW, CM, and DW and at 10℃ followed by 15, 20 and 25℃.
