Abstract
Filtering rates of two farming ascidians Styela clava and S. plicata, and of a farming mussel Mytilus edulis were experimentally investigated with reference to effects of water temperature and size. Absorptiometric determinations of filtering rates were carried out in a closed system with experimental animals being decreased indicate dyes neutral red. Optical density (OD) of 440 nm in path length 22 mm cell used as the indication of food particles absorption was appeared directly in proportion with the concentration of neutral red dyes. The filtering rate F is calculated by Kim's equation
근년에 내만성 굴양식장의 생산성이 저하함에 따라 대체종으로 미더덕과 횐멍게가 주목되면서 이 종들의 생태적 지위가 기존의 양식굴과 상충되는지 여부를 알아보기 위한 일련의 조사계획의 하나로서 여수율을 조사하였으며, 조사결과와 Kim (1995)의 양식굴의 여수율 (
