Blood parasites from fish of the Gulf of Maine to Cape Hatteras, Northwest Atlantic Ocean, with notes on the distribution of fish hematozoa
Examination of blood smears from 657 marine fish collected from the continental shelf off the east coast of the United States, Cape Hatteras to the Gulf of Maine, revealed hematozoa in 19 of 39 species. Among the infected fish species, hemogregarines were more prevalent (17%) than trypanosomes (5%),...
