harmful parasites of freshwater fishes. Reports on the damages caused
by copepod parasites from different parts on the world are increasing
alarmingly. But the information on parasitic copepods of freshwater

parasites, their Biology and pathology from Kerala. is lacking.
The thesis consists of five chapters. The first chapter is a
general introduction which deals with the review of literature on various
aspects of parasitic copepods viz; systematics, life history, host-parasite
relationship, ecology, pathogenicity, prophylaxis and control measures.
Systematics of parasitic copepods of freshwater fishes collected during
the present study forms the second chapter. The third chapter deals
with the life cycle study of the new Lernaeid copepod, Lernaea
osphronemi. The fourth chapter contains host-parasite relationship.
ecology and treatment of ‘the’ new species of Lernaea On
