Anadromous fish runs occur in rivers and streams that drain out of coastal ponds. These systems are used by migratory fish to feed and reproduce. These fish runs provide open and unblocked paths of travel for herring to reach their spawning habitat.

Herring spawn in these fresh water ponds and then live most of their lives in salt water, which is why it is essential to maintain these runs.

We stopped at one of the herring run rivers the other day and were surprised at the number of herring who were swimming upstream to get to the pond to spawn. You can see 4 herring that have just jumped up the little dam to get to the next resting place before they move on upstream again.

It was really fascinating to watch. Have you ever seen a herring run?
