摘要：

1. 1. Contrary to the generalization presently in the literature that fish sperm lack a powerful glycolytic system, the sperm of the shiner surfperch (Embiotocidae) and the guppy (Poeciliidae) exhibit a rate of glycolytic metabolism comparable to that of mammalian sperm. 2. 2. It is likely that sperm metabolism is supported by ovarian sugars during the period of prolonged viability within the ovary characteristic of these species. 3. 3. These results suggest that sperm metabolic systems are influenced by the environment in which fertilization occurs. © 1978.
