The invention provides a technique for preparing hermaphrodite scallop interspecific hybrid fingerlings, which relates to a marine shellfish breeding technique. Purple scallops and bay scallops are fattened and induced to be mature respectively so as to reach sexual maturity at the same time, and then are synchronously induced to lay eggs and discharge sperms respectively, so that sperms and eggs of two types of scallops are obtained respectively to perform interspecific cross insemination. The purple scallops and the bay scallops are hermaphrodite, both belong to an Argopecten category, have the same number of chromosomes, and have complementary superiority and traits. Hybrid groups are high in both fertilization rate and hatching rate and normal in larvae development. Two types of scallop parents adopted have complementary superiority and traits, thereby having significant heterosis in size, growth, adaptability and other aspects. As two types of scallops are both hermaphrodite, parent scallops are easy to purifym and the offspring with greater heterosis can be obtained by hybridizing the purified parent scallops.
