[Preliminary observation on feeding preference of Oncomelania for Sedum sarmentosum].
As a result of screening, we discovered that Sedum sarmentosum Bunge was most preferred among 317 kinds of snail food. Both adult and young snails readily eat S. sarmentosum as evidenced by laboratory observation and dissection of the snails. In aquarium, more snails were attracted by S. sarmentosum than by Chinese cabbage and Chlorella suspension. On water surface, S. sarmentosum curtains attracted adult snails 2.1-3.7 times and immature snails 2.3-4.1 times more than rice straw curtains.
