Abstract

The invention relates to hemifusus tuba artificial culture technology. The method utilizes a 20 m<2>culture pond. Cement boards with overspreading through holes are laid on the bottom of the culture pond; and the cement boards are 20cm away from the bottom of the culture pond so as to form space between the pond bottom and the cement boards. Then mesh cloth and fine sand are respectively arranged on the cement boards; a water inlet pipe is directly communicated with the pond bottom which is provided with a drain hole; and one end of the drain hole is extended out of the pond, while the other end of the drain hole in the pond is connected with a 70cm high plastic water pipe which is perpendicular to the water surface and is taken as a drain pipe. The initial density of released young snails is 400 to 500 pcs/m<2>; and with the growth of the individual young snails, the density is gradually reduced and the later stage culture density is 30 to 40 pcs/m<2>. During the water change, the water shoots up from the pond bottom through a sand layer; and due to the flushing action of the water, a great part of dirt in the sand layer such as the excrement of the hemifusus tuba is flushed away from the sand layer and is then discharged through the 70cm high drain pipe. Therefore, the culture environment is fully improved so as to benefit the growth of the hemifusus tuba, reduce the diseases, improve the survival rate, and simultaneously reduce the flushing frequency of the sand layer and consequently save much manpower.
