AbstractOf 797 fish of 28 species, 159 of 12 species yielded blood parasites. -- Eight species of protozoan parasites are reported - three each of Trypanosoma and Haemogregarina, and two of Haemohormidium. -- Trypanosoma rajae Laveran & Mesnil is recorded from Raja radiata. Undetermined trypanosomes are reported from Glyptocephalus cynoglossus and Gadus morhua respectively. -- Haemogregarina myoxocephali Fantham et al. was found in 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 H. delagei Laveran & Mesnil and H. platessae Lebailly. -- Haemohormidium terraenovae n. sp. Is described from six hosts:- Ammodytes americanus, Urophycis tenuis, Melanogrammus aeglefinus, Limanda ferruginea, Glyptocephalus cynoglossus and Hippoglossoides platessoides; and Haemohormidium beckeri n.sp. from Myoxocephalus octodecemspinosus. -- Intraerythrocytic inclusions of unknown origin were common in Clupea harengus and Argentina silus, and myxosporidans occurred as blood film contaminants in Raja radiata and Gadus morhua (in the latter case the parasite was referable to Kudoa sp.). Other artifacts reported were bacterial contaminants from Squalus acanthias and Limanda ferruginea.
