Effects of temperature on acoustic and visual courtship and reproductive success in the two-spotted goby Pomatoschistus flavescens.

Fish are ectothermic and small changes in water temperature could greatly affect reproduction. The two-spotted goby is a small semi-pelagic species that uses visual and acoustic displays to mate. Here, we studied the effect of temperature (16 and 20 °C) on acoustic and visual courtship and associated reproductive success in 39 males.
