U. S. Fish Commission 1872-1873, p. 666-689. 



Outlines effects of leeches on fish. The large blood-sucking leeches 

 attack fishes directly, even fishes of considerable size, and destroy them 

 very quickly by sucking their blood; other species are true parasites 

 of fishes and often, when numerous, do them much injury. Still others 

 destroy the food of fishes. Lists the species then known.
