Eastmain-1 Hydroelectric Development

Production of 234,000 sturgeons (2004-2008)

Overview of hatchery interior Exterior view of hatchery

Incubation of fertilized sturgeon eggs

Juvenile lake sturgeon nearly 10 cm long

Fertilized eggs

From 2004 to 2008, SEBJ produced lake sturgeon larvae and juveniles in a ­hatchery located at the Eastmain workcamp, with a view to stocking the Eastmain River with this species and introducing it into Eastmain 1 reservoir. The objective of this mitigation measure was to maintain the lake sturgeon population in the stretch of river below the dam while the Eastmain-1 infrastructures were being built, and to enhance Eastmain 1 reservoir. The measure was proposed in collaboration with the Cree trappers affected by the project.

Eastmain-1 Hydroelectric Development

Juvenile sturgeons in a stocking bag

The stocking operation proved more successful with sturgeon young-of-the-year, namely juveniles 6 to 10 cm long, rather than larvae. The juveniles have a higher potential for survival in natural environments than larvae because they are larger and perhaps because they have formed bone plates that protect them better from predators. The original objectives for larvae production and for stocking the Eastmain River and Eastmain 1 reservoir were exceeded. The introduction of sturgeon into Eastmain 1 reservoir will continue until 2012, and will be carried out by the Kaweshekami company under the supervision of the Niskamoon Corporation.
