Lake trout spawning project is underway

Ontario Ministry of Natural Resources personnel are here at camp to collect lake trout eggs to be raised in the Dorion fish hatchery and later released back to the lake.

This year the fishers are having a difficult time catching enough trout for the project due to the exceptionally warm water temperature. Trout don't come to their spawning shoals until the temperature is 10-11 C. At the start of the project a few days ago the temperature was 15 C.

It's now down to about 12 and some trout have been collected.

They are kept in underwater pens until enough of them are gathered. Then their eggs and milt will be stripped from them and the fish released back to the lake.

Here project manager Myles Perchuk brings a female lake trout to the pen.

The MNR hopes to collect about 120,000 eggs. Most of those will be raised to fingerlings in the hatchery and then brought back in a year and a half but some will also be placed in underwater incubator boxes to hatch naturally at various places around Red Lake.
