Grunion are caught by hand at night along beaches in southern California. Grunion leave the water at night to spawn on beaches during the spring and summer months.
These unique events occur for four consecutive nights, beginning on the nights of the full and new moons. Spawning occurs after high tides and continues for several hours.
Most spawning runs occur from March through August, with activity usually peaking from late March to early June.
The California Department of Fish and Game publishes a schedule of predicted spawning runs for California grunion. For more information about California grunion fishing, see:
