| Abstract: | The expansion of water resource development projects in the tropics and subtropics resulted in an increased transmission of human schistosomes. This study was conducted to test the feasibility of using two snail-eating fishes, Trematocranus placodon (Trewavas) and Maravichromis anaphyrmis (Trewavas), as biocontrol agents of schistosomes in fish ponds. The results suggest that T. placodon has a potential for controlling the snail vectors of Schistosoma mansoni (Sambon) and Schistosoma haematobium (Bilharz). The use of M. anaphyrmis, however, to control schistosome-carrying snails was not satisfactory. |
