Notice of permit

Regional or Local Number: 17-PCAA-00004

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. 17-PCAA-00004 is issued.

Activity affecting the species is incidental to the carrying out of the activity

The objective of the project is to apply selective lampricide to assess and control Sea Lamprey populations in the Great Lakes. Assessment surveys are routinely conducted in tributaries and lentic areas to determine the presence, distribution, and abundance of Sea Lamprey larvae. In deep water (>0.8 m) areas, surveys are conducted with the application of granular Bayluscide, a bottom-release formulation of lampricide, within the demarcated boundaries of the plots with a standard area of 500 m2. Tributaries harbouring larval Sea Lamprey are treated periodically with lampricides to eliminate or reduce larval populations before they recruit to the lake as feeding juveniles. The treatment units administer and analyze TFM, or TFM/Niclosamide mixtures (TFM augmented with Bayluscide 70% wettable powder or 20% emulsifiable concentrate) during stream treatments, and apply 3.2% granular Bayluscide (gB) to control populations inhabiting lentic areas.

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Ontario

Affected Species:

a) Alternatives: Assessment locations are selected based on available habitat, larval Sea Lamprey occurrence and historical records. As such, alternatives to the selected survey locations typically do not allow for the effective assessment of larval Sea Lamprey. Assessment and control treatments for Sea Lamprey follow standardized procedures. These procedures are designed to control Sea Lamprey populations while minimizing impacts to non-target organisms. This is the most suitable option for the management of Sea Lamprey in the areas described. b) Measures to minimize impact: The application of lampricides for the purposes of assessment and treatment of sea lamprey is routinely conducted throughout the Great Lakes Watershed. Tributaries and lentic areas are treated following standard operating procedures. These application standards are reviewed annually by an international panel of scientists who specialize in invasive species control. In Canada, the implementation of these procedures is completed by experienced DFO personnel certified in the application of lampricides. All lampricide applications are done so under the Ontario Ministry of Environment permitting process, and are authorized under the Fish Toxicant Regulations of the federal Fisheries Act. c) Effects on survival and recovery: The project will not jeopardize the recovery or survival of species at risk fishes or mussels as lampricides are highly selective, thus reducing the likelihood of non-target mortality. Although less selective than TFM, Bayluscide remains highly selective for lamprey in the dosages used. Applications are infrequent, usually once every 3-6 years.
