The 2018 Mystic River herring run is over. We want to thank you for all the effort you put into counting the Mystic River herring run videos this season!
We hope to have more video counting opportunities in a few weeks, exciting additional studies that we think you might find fascinating. And, the official herring count will come out in August.
In the meantime, here are some numbers that describe the 2018 count. Most of these numbers would be zero if it weren’t for you.
