摘要：

Relatively small differences in size reduced spawning success in crosses of two paired species of lampreys. Typical spawning behavior occurred between the two species in all experiments, but minimal fertilization occurred when females were more than about 20% larger or smaller than males. The results support the hypothesis of Hardisty and Potter (1971) that homogamy is the general mechanism that results in the establishment of paired species of lampreys.
