J.O. Cheikyula, D.T. Anju, A.A. Garba


This study was carried out to assess the changes in haematological indices in Heterobranchus longifilis juveniles exposed to aqueous bark extract of Tephrosia vogelii. The experimental fish were obtained from the wild and transported to the Department of Fisheries and Aquaculture, University of Agriculture, Makurdi, Nigeria for two weeks acclimatization. Ten (10) fish of average weight 115.25+ 25.00g were selected randomly, injected intramuscularly (IM) with aqueous bark extract of T. vogelli using five concentrations of 0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 g/l with replicates. Control fish were injected with distilled water. Blood was collected and analyzed for changes in some haematological indices. Result obtained showed no significant (P>0.05) changes in the Haematological indices considered.
