Abstract

A non-random distribution of cysts of Nematopsi.s along the mantle margin of oysters was discovered. Sampling sites must be carefully chosen for cornparative studies. When oysters with high and low initial infections of Nematopsis were transplanted into areas of low and high infestation respectively, the transplants attained the characteristic level of inf'ections of native oysters in that area. Presumably a dynamic equilibrium of elimination and reinfection of the parasite was reached. Spores discharged from living oysters may infect crabs.
