Catch and Release Regulation Placed on Stoney Lake (Siler Lake)

Over the summer Stoney Lake experienced a significant summer kill. Conservation measures are needed in order to allow fish populations to recover. A zero harvest limit has been put in place to address this need.

Stoney Lake is located near Elk Point at the legal land location of 56-08 W4M.

Signage has been placed at various access points along the lake to notify public about the regulation change.

Why did Alberta Environment and Parks (AEP) change the angling regulation from pike limit 1 over 63 cm/perch limit 10 to pike limit zero/perch limit zero?

A fish kill occurred in August, 2016. A significant number of dead Pike and Perch were observed along the shoreline of Stoney Lake. A harvest closure is necessary to protect the surviving fish from harvest, and a closure will also allow the maximum number of spawning fish to re-establish the fishery.

What caused the fish kill in Stoney Lake?

The kill may have been caused by an algal bloom. Subsequent death and decomposition of the algal material may have led to reduced dissolved oxygen in the lake. Limited or rapid declines in oxygen levels can cause stress and mortality of fish. Other related causes, if prevalent, may have been due to toxins released from blue-green bacteria (e.g., Microcystin) in the algal bloom, which can also cause stress in fish.

I have caught several yellow perch during the winter, why can’t AEP open the fishery now?

A process is in place to ensure speedy recovery of fish populations in the event of a significant die off. AEP will need to determine the significance of the fish kill (i.e., number of remaining young fish and spawning fish) by:

  1. assessing the fishery when fall water temperatures are appropriate for the sampling methods;
  2. determining if there is an adequate number of young and spawning fish remaining;
  3. determining an appropriate angling regulation to maintain a sustainable fishery; and
  4. consultation and/ or notification with stakeholders.

It is anticipated by mid-winter that results will be available and management actions will be proposed.

This winter, I had observed too many people fishing at Stoney Lake, how can AEP prevent this from happening?

AEP cannot prevent anglers from legally fishing a lake; however, the angling regulation may determine the lake they choose to fish at.
