The spawning host selection and adaptive characteristics in life history were investigated for Sarcocheilichthys nigripinnis morii which has similar habit of spawning with acheilognathine fishes. The fertilized eggs of the species were found in the mantle cavity of Corbicula papyracea and C. fluminea among the bivalves collected from same locality, meaning the species specific host selection for the spawning. We considered that the differences in the status of expanding egg membrane after hydration, fewer number of eggs settled into the mantle cavity and having eleutheroembryo with developed organ would be some evidences of specific reproductive strategy for this species. But the status of developed surface blood circulation was thought to be a compensation for the parasitism. The pigmentation of melanopore delayed to late embryo and the spot on the caudal region was a characteristics of this species appeared in the early life history.
