Haemogregavina sachai n.sp. from cultured turbot Scophthabnus maximus (L.) in Scotland

Abstract. A new species of pathogenic haemogregarine is described from farmed turbot ( Scophthalmus maximus L.) as Hamogregarina sachai and its life cycle is demonstrated in its final host. An intralexicocytic schizogony followed by an intraerythrocytic schizogony was observed. This appears to be only the second time that a complete life cycle in the vertebrate host has been described for a marine fish haemogregarine.
