The Bluewater Anglers are holding their annual open house at their hatchery under the Bluewater Bridge this weekend.
Director Brad Armstrong says they have thousands fish in the hatchery, filling up eight of their nine tanks.
He says they gather the eggs around Thanksgiving.

Armstrong says they wait for the water temperature to reach about 10 C before releasing the fish, typically in late April.
The open house is Saturday and Sunday from 10pm-4am.
