New Host and Locality Records for Two Protozoan (Myxosporea, Coccidia) Parasites of Marine Fishes

Abstract

This is the first report of the myxosporean Ortholinea orientalis from Atlantic herring Clupea harrengus. It infects the kidney tubules and previously was known from Pacific herring Clupea pallasii and navaga Eleginus navaga in the White Sea and North Pacific Ocean. This is also the first report of the coccidian Eimeria raibauti from Norway pout Trisopterus esmarkii. It infects the epithelium of the pyloric ceca and previously was known only from poorcod Trisopterus minutus in the Mediterranean Sea. The new records are both from the northern North Sea.
