The most important natural beds and cultured zones of clams (Ruditapes decussatus, R. philippinarum, Venerupis pullastra and V. aureus)on the coast of Huelva (S.W. Spain) were sampled in March 1989. The distributions and prevalences of the different observed parasites are presented. Perkinsus atlanticus and Minchinia tapetis were the most worrying parasites detected. P. atlanticus was the agent observed with the highest distribution and prevalence, showing a special incidence in R. decussatus . An intensive hemocytic response encysting the parasite and destroying the tissue structure was related to P. atlanticus.
