title: Comparative study on the toxic effects of red tide flagellates Heterocapsa circularisquama and Chattonella marina on the short-necked clam (Ruditapes philippinarum).
abstract: Heterocapsa circularisquama showed much higher toxic effects on short-necked clams than Chattonella marina. Clams exposed to H. circularisquama exhibited morphological changes concomitant with an accumulation of mucus-like substances in the gills, a profound reduction in filtration activity, and lysosomal destabilization in hemocytes. Chattonella marina was less effective than H. circularisquama, and Heterocapsa triquetra was almost harmless in all these criteria. These results suggest that H. circularisquama exerted its lethal effect on short-necked clams through gill tissue damage and subsequent induction of physiological stress.
