During the late afternoon, after spawning had subsided considerably, the fish were very skittish, males and females leaving the area permanently at the slightest provocation. By 4 no fish were observed on the spawning ground. On June 15th eggs were extremely abundant on the algae-covered rocks, in some cases forming a solid crust. On June 16th it was almost impossible to locate eggs. The few that were found were well along in development, with hearts beating, indicating that development is rapid, as in other centrarchids. A female inches long snagged off the spawning bed contained an estimated 84,000 unspawned mature eggs. The first Sacramento Perch of the year were taken in Clear Lake on June 9, 1947, at an average length of of an inch, w^hich indicates that spawning had begun in May. By June 24th the majority had spawned, judging by the condition of the gonads of adults captured in nets. Dur- ing the period May 19th to June 26th the water temperatures of Clear Lake at a depth of two feet varied from a maximum of 84 degrees F. to a. Figure 27.
