Abstract

Laboratory-reared marbled flounder (Pleuronectes yokohamae) juveniles ($23.2{\pm}0.2mm$ total length; age 89 day) were sampled over a 48-h period to determine any diel patterns in RNA/DNA ratios. RNA/DNA ratios were highest during daytime periods (0800, 1100, 1400, 1700 h) and significantly reduced at night (2000, 2300, 0200, 0500 h). Findings from this study indicate a diel variation in biochemical condition and suggest that special care should be taken in designing sampling plans, including sampling time and data analysis to account for this source of variability.

문치가자미 Pleuronectes yokohamae의 RNA/DNA비 일주기 변화를 조사하기 위하여 부화후 89일, 전장 $23.2{\pm}0.2mm$의 치어를 48시간 동안 일정한 시간 간격으로 채집하였다. RNA/DNA비는 주간(0800, 1100, 1400, 1700)에 높았고 야간(2000, 2300, 0200, 0500 hours)에는 낮게 나타났다. 이번 연구결과에서 문치가자미의 생화학적 일주기 변화를 확인하였고, 이와 같은 RNA/DNA비의 일주기적 변화를 고려하여 시료 채집시간 결정을 포함한 시료채집 계획작성과 data분석이 필요할 것으로 생각된다.
