Notes

Formal training in identification of the nematodes encountered in fresh, brackish or salt waters is offered in relatively few academic institutions. Usually, information must be sought in abstruse books and reprints which may be difficult to obtain, and may contain confusing morphological terminology. The key that follows is based on published reports of nematodes found in fresh water and, in part, fresh water intruded by salt water. It was devised with the intent of offering brief, relatively simple choices and providing the user with visual illustrations of specific nematode morphology. Original drawings, photocopies of published drawings, and redrawing of original illustrations were used. The key was constructed in order that those with biological training could use it without undue difficulty. It is scheduled for inclusion in "Standard Methods for the Examination of Water and Wastewater", 15th edition.
