Grunion Watch this Weekend

They're back!  Those little slippery silvery fish that reclaim their beaches every so often to spawn will be on Venice and Dockweiler beaches tonight and Saturday night.  The best times to OBSERVE the Grunion Run will be after 11 PM tonight and after midnight on Saturday.  With the warm weather we've been having, tonight should be very pleasant for grunion watchers.

April and May are closed season for grunion take, so you can only watch the little wrigglies as they invade the sandy beaches and spawn.  If you've never seen this phenomenon, you should put it on your bucket list.

One year I was on Venice beach a few hundred yards north of the Marina jetty.  We had been waiting nearly an hour for any sign of grunion, when all of a sudden, a wave brought in tens of thousands all at once.  As the wave retreated, there was hardly a sandy spot on the shoreline - the entire beach was carpeted with grunion for hundreds of yards.   Then, they all disappeared with the next wave, only to reappear further down coast on a subsequent wave.

The female digs into the wet sand tail first in order to deposit her eggs at a safe depth, while as many as eight males wraps themselves around the female and release their milt.  In that instant before the next wave comes up onto the beach, the eggs are fertilized.  The eggs stay in the sand for about 10 days and hatch during the next high tide series, when the little fry wriggle out of the sand and swim into the ocean.
