Linear regressions of fecundity, ovary weight and body measurements of Sacramento suckers from Thomes Creek, Tehama County, 1981. During the spawning migration, some females were observed with well-devel- oped pearl organs. They appeared as small pearl-like spheres on the anal, caudal, and pelvic fins. Very few males were observed with pearl organs. The spawning act of Sacramento suckers is similar to that of the white sucker. Sacramento suckers generally spawn on shallow riffles in groups comprised usually of six to seven males centered around one or two females. Spawnings usually lasted no longer than 2 h. There also seems to be no preference for time of day or amount of light. Eggs were adhesive, but usually they did not stick to the substrate; rather they picked up small bits of debris that allowed them to roll along the bottom with the current until they settled out among the interstices of the substrate or in the shallow stream margins where there was little or no Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
