COAST CITIES — Join Birch Aquarium at Scripps Institution of Oceanography, UC San Diego, for a must-see ocean adventure. From March 28 until early June, observe the mysterious grunion spawn on the beaches of La Jolla.
The first gathering to witness the grunion run is set for 10:30 p.m. to 12:30 a.m. March 28, with a special presentation by Karen Martin, Pepperdine University marine biologist and grunion expert. Other events will be held 9:30 to 11:30 p.m. April 10; 10 p.m. to midnight April 11; 9 to 11 p.m. May 9; 9:30 to 11:30 p.m. May 25; and 9:30 p.m. to 11:30 p.m. June 8.
On certain spring nights following high tides, hundreds of the small, silvery fish ride the waves onto shore for this remarkable mating ritual. While on the beach, female grunion bury themselves in the sand to lay eggs, while males wrap themselves protectively around the females to fertilize their eggs. Both catch a wave to return to sea.
Birch Aquarium at Scripps naturalists will guide participants through an unforgettable night, starting with a presentation on grunion, followed by a rare opportunity to witness grunion eggs hatch before their eyes. The unique experience continues with a moonlight beach exploration. Please bring a flashlight and warm jacket. The program is $12 per person. Please note that Grunion Runs do not take place at Birch Aquarium at Scripps. Reservations must be received in advance by calling (858) 534-7336.
