Abstract: 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 eai S, sarmentosum as evidenced by laboratory observation and dissection of the snails.In aquarium, more snails were attracted by S. sarmentosum than by Chunese cabbage and Chlorella suspension. On water surface, S. sarmentosum curtains attracted adult snails 2.l-3.7 times and immature snails 2.3-4.1 times more than rica straw curtains.
