VERIFICATION OF THE DELETERIOUS EFFECTS OF LERNAEOSIS ON THE HEALTH OF GRASS CARP (CTENOPHAR YNGODONIDELLA)
Experimental infestation of Ctenophuryngodon idella (80-90 g) with laboratory reared first copepodid stage of Lernaea cyprinacea (a parastitic copepod ) resulted in clinical lernaeosis. The mortality rate reached up to 40% of the infested group within <a month at 26 ± 2°C. The sequential clinical abnormalities, histolopathcrilogicai and hematological alterations with elevation in the cortisol lewd had verified experimentally the deleterious effects of lernaeosis* on the health of G idella. Periodical examination of the experimentally infested C. idella cleared that the females parasites were tlfrie most physically detrimental stage to-the. fisfcv withe regard to their ranode of attachment and cortisol response. Induction of lernaeosis in the present investigation may be important when attempting to develop useful effective protective and / or curative measures for lernaeosis in G idella and probably in other cyprinids.
