Abstract
The reproductive periodicity of the Atlantic silverside, Menidia menidia, was studied at two locations on the North Edisto River estuary in South Carolina during March - July of 1976-1978. Spawning runs occurred in the upper intertidal zone and coincided precisely with daytime high tides. Time series analysis of daily changes in the intensity of spawning runs revealed a fortnightly reproductive periodicity. Additional analyses indicated that the observed reproductive rhythmicity in M. menidia may be mediated by a high tide- sunrise cue, that also occurs at fortnightly intervals.
