摘要	The rapa whelk Rapana venosa transforms from a phytophagous larva to a carnivorous juvenile after settlement and metamorphosis. The high mortality rate and low metamorphosis rate(<1%) of larvae are among the key factors limiting the recovery of the resources of R. venosa. We studied these two processes and showed that the larva has the ability to settle and metamorphose in the middle and late 4 spiral whorl period, and the use of substrates(scallop shells with oysters) can signi?cantly improve the settlement and metamorphosis rate of larvae. The presence of darkness, juvenile bivalve shell?sh, and oyster polysaccharide could ef fectively increase the rates of larval settlement and metamorphosis. Our ?ndings broaden the understanding of settlement and metamorphosis in gastropods and can be used to improve population control, resource recovery and commercial breeding strategies for R. venosa.
