Abstract: Bluefin killifish mate preference is best detected using mating behaviors, such as the number of courting bouts or the number of eggs produced with a mate. Using these measurements, we found that female bluefin killifish that co-occur with a close evolutionary relative have stronger mate preferences for their own species than their male counterparts, and even show increased mate preference for individuals from their own population.
