Nunavut Restricted Activity Timing Windows for the Protection of Fish and Fish Habitat

Restricted activity timing windows have been identified for Nunavut lakes, rivers and streams to protect fish during spawning and incubation periods when spawning fish, eggs and fry are vulnerable to disturbance or sediment. Restricted activity periods are determined on a case by case basis according to the species of fish in the water body, whether those fish spawn in the spring, summer or fall, and where the water body is located.

How To Determine Timing Windows

1. Determine if the water body is in Zone 1 or 2 according to Figure 1.
2. If the water body is in Zone 2, determine the fish species living in the water body where you wish to do work.
3. Determine whether the fish living in the water body spawn in the spring or fall according to Table 1. Where both spring and fall spawning fish are present, or if it is unknown what species are in the water body, both timing windows should be combined to adequately protect all species.
4. Using Table 2 below determine the in-water work timing restrictions according to the location of a water body (Zone 1 or 2) and whether the species in the water body spawn in the spring or fall. During these periods work should be avoided.
