Sarnia-Lambton residents are being invited to get a first hand look at operations at the Bluewater Anglers hatchery.
An open house is planned for March 18 and 19.
The hatchery tanks are filled with thousands of pacific salmon, brown and rainbow trout.
They'll be released into local waterways ahead of the upcoming fishing season. Some domestic trout will be put into the pond at the hatchery for the children to feed.
Spokesman Ross Bishop said they raised the fish from an egg, and many of them are now the size of a finger.
"We'll be there explaining all of the fish, and also it's to show people the schools that we have involved with us to raise our salmon," said Bishop. "What we've done is we've taken some wood and carved it into the shape of a fish. We take them to the schools, and the kids paint them and we hang them up in the hatchery for everyone to see."
The open house is being held from 10 a.m. until 3 p.m. Saturday and Sunday.
Sarnia-Lambton MPP Bob Bailey will be on hand to recognize improvements made to the hatchery under a grant from the Ontario Trillium Foundation.
It has allowed the Bluewater Anglers to improve air quality in its boardroom and classroom by adding air purification equipment and also by adding an additional exterior door.
Bishop said hot dogs and other refreshments will be provided.
Bluewater Anglers' memberships will be available, and they'll be selling tickets for the salmon derby which will take place from April 28 to May 7.
The hatchery is located just north of the Blue Water Bridge.
