Abstract
Oreochromis aureus exhibits a diel periodicity of spawning when mainta ined on a controlled 14:10 Light:dark photoperiod, with a peak in spaw ning activity during the 11th hour of light. That this periodicity of spawning is a response to light is supported by phase-shifting the lig ht cycle by seven hours. This results in a corresponding shift in the time of spawning.
