spring herring in the Cove

Herring made there first big appearance in the Cove this year March 15.  They may have been around earlier but it is hard too see them unless it is quite calm and not raining.  There haven't been predators or birds making them obvious, and on this day that was the case again.  They flowed through the Cove moving north in clusters and spread all across the surface .
I'm guessing that most of these are out-bound mature herring, heading back to the outside ocean after spawning. But again, as in previous years, there are also smaller herring about ,4 inches, too small to be spawners.
