黑暗条件下缢蛏（Sinonovacula constricta）对牟氏角毛藻（Chaeroeeros moelleri）和青岛大扁藻（Platymonas subcordiformis）的滤食效应

The effect of filter-feeding in dark by Sinonovacula constricta on Chaeroeeros moelleri and Platymonas sub-cordiformis was studied. The result show that the pattern of functional response in S.constricta to C.moelleri and P.subcordi-formis is of Holling-II type, the fitted Holling's disc equations are (The equation is abbreviated) and (The equation is abbreviated) respectively, while that of density to C. moelleri and P.subcordiformis are E=0.985P^(-1.0256) and E=0.778P^(-1.1819); The associated response equations between the density of S. constricta and C. moelleri, and that of S.constricta and P.subcordiformis are (The equation is abbreviated) and (The equation is abbreviated) respectively. In addition, the filter-feeding rate, the type of functional reaction and the effect of S.constricta on algae were studied.
