N2 - Abstract. Segments of the kidney tubules of about 16% of cod caught in the approaches to Halifax Harbour were found to contain a coccidian parasite. Macrogametes developed in an epicellular position, and microgamonts, unsporulated and sporulating oocysts, and free sporocysts, were found in the lumen of the kidney tubule. The epithelial cells of the kidney tubules were damaged and granulomas often formed around infected tubules. The presence of a suture dividing the sporocyst wall into two valves could only be determined using electron microscopy. Other coccidians which have been placed in the genus Eimeria because sutures could not be seen using light microscopy, although no Stieda body was present, may also belong to the genus Goussia. No other coccidians have been reported in the kidney tubules of marine fish, and the name Goussia spraguei sp. nov., is proposed.
