Abstract
The speckles dace Rhinichthys osculus [Girard] is the most widely distributed and ubiquitous fish in the western United States (Moyle, Inland Fishes of California, 1976). Although common, very little information is available concerning thje reproductive behavior of speckled dace or the environmental cues which trigger spawning activity. Several hundred speckled dace were observed spawning in the San Francisco River, 4.8 km upstream from Reserve, Catron County, New Mexico, on June 2-3, 1981. Spawning was in an area of disturbed substrate at a time when other reaches of the streambed were overgrown with diatoms, filamentous algae, and macrophytes. This note described the spawning site and reproductive behavior and proposes that physical disturbance is a major cue for reproductive activity in the species.
