Duration of the work

2003-2008

Summer 2004

Producing and returning more than 71,000 lake sturgeon larvae to their environment.

Winter 2004

Lake sturgeon: development of sturgeon spawning grounds.

2003

Study documenting the migrating habits of sturgeons and characteristics of their habitats.

Our actions

Our reasons for acting

Work area: Territories of the future Eastmain 1 reservoir / Eastmain River

Improving or creating reproduction sites and developing spawning grounds

We will develop spawning grounds to help various species of fish, mainly walleye and lake whitefish, to reproduce.

We will thereby compensate for the loss of habitats caused by impoundment of the Eastmain 1 reservoir. In addition, the development of spawning grounds in certain tributaries will increase the environment's productivity.

Improving the lake sturgeon's habitat

We will develop lake sturgeon spawning grounds at kilometre points 203 and 207 of the Eastmain River as well as at the mouth of the Rivière à l’Eau Claire. At kilometre point 207, we will build a dike letting a little water through (weir) as well as a migration structure. Finally, we will produce larvae and release them into the environment

Developing a spawning ground
at KP 203 in the winter

The Eastmain River's lake sturgeon is very important to the Crees. It is also interesting, ecologically speaking. The development will compensate for the loss of the sturgeon spawning ground at kilometre point 215.

Improving reproductive success

We will produce lake sturgeon larvae and release them into the environment to condition existing spawning grounds. These measures will be carried out over several years, beginning in 2004. Activities will be conducted in spring, during the spawning period, working closely with Crees involved in the project.

Incubation of fertilized eggs

This is another way of compensating for the loss of the sturgeon spawning ground at kilometre point 215 of the Eastmain River.
