Breeding salmon may help understand human fertility

Male salmon appear to have a clever way to get ahead of their breeding rivals.

A Canterbury University study has found chinook salmon can adjust their sperm's swimming speed, when competing with a rival to reproduce.

PhD student Michael Bartlett says the adjustment of sperm velocity alters male reproductive success and therefore fitness.

He said it's probably not a conscious decision by the fish.

"It's a physiological response by the fish in response to those cute signals from various things."

Bartlett is continuing the study in an effort to try to learn more about human fertility.
