Abstract
부영양화 호소수에 대한 국내 서식 펄조개(A. woodiana)의 유기물 제어 실험 결과, 펄조개 30개체를 대상으로 패각 크기 4.3~15.5 cm (평균 9.54 cm)에 따른 유기물 여과율은 0.08∼0.86Lg?1h?1 , 단위 건중량당 펄조개의 여과율은 0.09Lg?1h?1 를 나타내었다. 펄조개의 배설물 생산량 (PF)은 0.00∼11.10mgg?1h?1 , 단위 건 중량당 배설물 생산량은 0.37mgg?1h?1 를 나타내었다. 또한, 클로로필-a와 부유물질 제거율(RA, %)은 느린 유속에서 82.1%, 71.0% 빠른 유속에서는 65.4%, 57.5%의 제거율을 나타냈고, 반응표면분석 결과, 패각 크기는 14.3~15.6 cm, 유속은 22∼30Lh?1 구간에서 여과율 6.21Lmussel?1d?1 의 최적값을 나타내었다. 또한, 배설물 생산능은 패각 크기는 14.3~16.3 cm, 유속은 36∼44Lh?1 구간에서 배설물 생산이 4.2mgg?1d?1 의 최적값을 나타내었다.This study was conducted to establish models of filtrating rate and production of feces of a native freshwater bivalve, Anodonta woodiana, on removal organic matters in eutrophic waters. Among the applied shell size (4.3~15.5 cm), the filtrating rate and production of feces of Anodonta woodiana was 0.08∼0.86Lg?1h?1 (average 0.24Lg?1h?1 ), 0.00∼11.10mgg?1h?1 (average 0.94mgg?1h?1 ), respectively. In two different water current (high 48Lh?1 , low 24Lh?1 ), the filtrating rate of Chl-a was 0.02∼0.10Lg?1d?1 (average 0.05Lg?1d?1 ), 0.02∼0.11Lg?1d?1 (average 0.07Lg?1d?1 ) and the removal rate was 65.4%, 82.1%, respectively. Response surface methodology, with a central composite design comprising 3 levels and 2 variables, was used to identify the optimal removal condition of shell length, water current and filtrating rate or feces production by bivalves. The optimum removal conditions were found that had optimized 6.21Lmussel?1d?1 at shell length 14.3~15.6 and water current 22∼30Lh?1 . The optimal conditions of production of feces ( 4.2mgg?1d?1 ) by freshwater mussels were shell length 14.3~16.3 cm and water current 36∼44Lh?1 .
