Marine fish haematozoa from Newfoundland waters

Of 797 fish of 28 species, 159 of 12 species yielded blood protozoa. Trypanosoma rajae is recorded from Raja radiata. Undetermined trypanosomes are reported from Glyptocephalus cynoglossus and Gadus morhua, respectively. Haemogregarina myoxocephali is listed from the type host, Myoxocephalus octodec...

Description
Summary:Of 797 fish of 28 species, 159 of 12 species yielded blood protozoa. Trypanosoma rajae is recorded from Raja radiata. Undetermined trypanosomes are reported from Glyptocephalus cynoglossus and Gadus morhua, respectively. Haemogregarina myoxocephali is listed from the type host, Myoxocephalus octodecemspinosus. The occurrence of haemogregarine sporozoites (perhaps of this species) in the gut of a piscicolid leech (Malmiana nuda) from Myoxocephalus scorpius represents the first discovery of a potential vector of any fish haemogregarine. New hosts are listed for Haemogregarina delagei and H. platessae. A babesioid Haemohormidium terraenovae n. sp. is described from six hosts: Ammodytes americanus, Urophycis tenuis, Melanogrammus aeglefinus, Limanda ferruginea, Glyptocephalus cynoglossus, and Hippoglossoides platessoides; and another, Haemohormidium beckeri n. s p., from Myoxocephalus octodecemspinosus.
