Mosquito Larvivorous Potentiality of Oreochromis niloticus (Perciformes:Cichlidae) and Lepidocephalichthys guntea (Cypriniformes:Cobitidae) in Density Dependent and Time Dependent Laboratory Bioassay
Subscribe/Renew Journal
Present study was carried out to evaluate the mosquito larvivorous potentiality of two larvivorous fishes (Oreochromis niloticus and Lepidocephalichthys guntea) in laboratory condition against the larval form of Culex quinquefasciatus. Results of the density dependent bioassay study indicated that the predation rate of the O. niloticus was higher than L. Guntea all prey densities. The predation rate at light-on phase was higher than light-off phase in both the fish species and the consumption rate was higher in presence of river water than in tap water.
