| Abstract |
The reproductive rhythmicity of the false grunion, Colpichthys regis, was observed in the Estero del Soldado, Mexico during October 1982 through January 1983. Spawning runs occurred at approximately 2-week intervals during daytime high tides. These high tides coincided with new and full moons. Spawning only occurred when predicted tidal heights were equal to or greater than 0.73 m above MLW. Eggs were deposited in the upper intertidal zone in locations that appeared to provide protection from predators, thermal stress and desiccation. |
