Abstract The freshwater sponge, Ephydatia fluviatilis (Porifera: Spongillidae), was maintained in a continuous-flow laboratory culture system under several conditions of calcium ion (Ca++) concentration and salinity. Experimental results suggest that sponge growth rate increases with increasing Ca++ concentration, that sponge growth rate decreases with increasing salinity, and that the negative effect of higher salinity can be overcome by increasing Ca++ concentration. The experimental results correlate well with field observations on the effects of salinity and Ca++ on the distribution of E. fluviatilis.
