FEEDING ECOLOGY OF ERIOCHEIR SINENSIS,PROCAMBAEUS CLARKII AND MONOPTERUS ALBUS

Eriocheir sinensis, Procambarus clarkia and Monopterus albus was reared in net enclosure in Malaria and Schisstisimiassis area to investigate the feeding habits. A feeding trial was also conducted in net enclosure to investigate the food consumption on Oncomlania and mosquito larvae. The results showed that the animals can consume both Oncomlania and mosquito larvae. Daily intake of each Eriocheir sinensis was 62.4ind. on mosquito larvae, 4.8ind. on Oncomlania. Daily intake of each Procambarus clarkia was 17.6 ind on mosquito larvae, 0.9 ind. on Oncomlania. Daily intake of each Monopterus albus was 8.1 ind. on mosquito larvae, 0.7 ind. on Oncomlania. It shows that these three animals could be used to control the population of Oncomlania and mosquito.
