  • Tiny (3- to 6-ounce) fish found along the Southern California coast, known for their spawning habits. The "running of the grunion" occurs by the light of the full moon as these silvery fish wriggle their way above high tide to spawn in the wet sand. Legally, grunion can only be caught by hand, though many people snare them with nets or scoops. The moderately fat grunion are best broiled, deep-fried or sautéed

  • Merriam-Webster Dictionary:
    noun
    Etymology: probably from Spanish gruñón grunter
    Date: 1917
    : a silverside (Leuresthes tenuis) of the California coast notable for the regularity with which it comes inshore to spawn at nearly full moon

    As a child growing up in California I remember the "grunion run" when crowds of people would assemble on the beach in the moonlight and scoop up dozens and dozens of the grunion fish as they came inshore to spawn. In those days I thought it was quite a fun and festive time but now it seems unfair and cruel.
