Unveiling the Marvel of Southern California’s Grunion Run
By Melani Morose Edelstein, Community Reporter
When night falls along the sandy shores of Southern California, a peculiar spectacle unfolds. Thousands of silver flashes dance amidst the moonlit waves, drawing the curious gaze of those fortunate enough to witness it. What could possibly lure fish out of their aquatic realm and onto the land under cover of darkness? The answer lies in the enchanting phenomenon known as the grunion run.
“Undoubtedly the most unique thing about grunion is that they are a fish that comes out of the water to spawn! It’s a rare opportunity to see a fish engage in reproduction without having to venture out into the ocean,” enthuses Crislyn McKerron, executive director of the Cabrillo Marine Aquarium.
Grunion runs are not merely a sight to behold; they are a testament to the intricate rhythms of nature. These small silvery baitfish, scientifically known as California grunions (Leuresthes tenuis), embark on their spawning journey under the cloak of darkness, riding the waves ashore to lay their eggs upon the sandy beaches.
It’s a scene straight out of folklore, yet here in Southern California, it’s a tangible reality.
San Pedro’s own Cabrillo Marine Aquarium, nestled along the coast, embraces the opportunity to share this marvel with the public.
“Cabrillo Marine Aquarium loves taking the public out to witness the majesty that is a grunion run. It never gets old,” McKerron says. Indeed, there’s an undeniable allure to watching the beach come alive under the moonlight, as nature unfolds its mysteries before our eyes.
If you’re eager to partake in this extraordinary experience, meticulous planning is essential. Charting the moon and tide cycles becomes a ritual, ensuring you’re at the right place at the right time. McKerron emphasizes the importance of respect for nature’s cycles, urging visitors to adhere to regulations during closed seasons, allowing the grunion to spawn undisturbed.
Unlike other fish, grunion are considered cooperative because they reliably show up on schedule, something you can’t count on with many other species.
Popular coastal spots for observing grunion include Cabrillo Beach, Seal Beach and Doheny State Beach in Dana Point. However, these fish can appear on any sandy, sloped shoreline. To partake in this nocturnal adventure responsibly heed some expert advice:
*Visit during the full moon, as it provides better visibility. Avoid using bright headlamps, which might scare the fish away. You can see the silvery fish well once your eyes adjust to the dark.
*Embrace both stealth and silence; grunion are easily spooked. Keep lights off and remain inconspicuous until the run is well underway.
*Leave the scouts, the first fish to arrive, undisturbed. These scouts check the scene and, if it’s safe, signal the others to come ashore.
*Follow the regulations: only take when permitted and adhere to the bag limit. This ensures the species can continue to thrive.
*Seek out expansive sandy beaches with open access to the ocean, avoiding harbors, estuaries, and lagoons with restricted entry.
* The third and fourth nights of the run typically offer the most reliable sightings.
* Look out for telltale signs such as circling or landing birds, indicating the presence of grunion.
* Respect the phenomenon and remember only hands are permitted for catching grunion. No buckets or other receptacles are allowed. The daily possession limit is 30 fish per person.
As the warm summer months envelope Southern California, the anticipation of the grunion run grows palpable. It’s not just a natural spectacle; it’s a celebration of life, a reminder of the enchanting mysteries woven into the fabric of our coastal landscapes.
So, heed the call of the moonlit shores, and immerse yourself in the magic of the grunion run.
