Notice of permit
Regional or Local Number: DFO-17-PPAC-00020
Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-PPAC-00020 is issued.
Scientific research for the conservation of the species
The activities authorized by this permit consist of: a) installation and daily monitoring of milk crate traps or spawner net traps, b) electrofishing for ammocoetes in shallow water, c) holding of individuals for a maximum of 15 minutes while d) length measurements are taken and e) developmental stage is identified, followed by f) immediate release to the wild.
Start Date: 2017-07-07 End Date: 2017-09-01
Issuing Authority: Department of Fisheries and Oceans
- Species at Risk Act
Location of Activity (province, territory or ocean):
- British Columbia
a) Alternatives: Activity a) is prioritized first because of its lower potential impact on the species. Activity b) is proposed as an alternative to activity a) when activity a) proves to be ineffective in a given section of the study area. Activity b) is considered by species experts to be a reliable method of surveying for Vancouver Lamprey ammocoetes. Activity c) has a low impact and is necessary for length measurement. Activities d), e), and f) address the purpose of the project and do not pose a risk to the individuals of the species. b) Measures to minimize impact: For activities a) and c), captured lampreys will be handled carefully as per best practices, and condition of individuals will be monitored while they are being held; an aerator will be used to maintain oxygen levels in the bucket. For activity b), observers will visually scan the target area for spawning adults prior to electroshocking. If adults are observed, exclusion nets will be employed. If a spawning mass or redd is observed, the area will not be electroshocked. During electroshocking, condition of the lampreys will be examined upon capture to assess potential injuries. If any injuries are observed, voltage will be reduced until injuries are eliminated. Electroshocked lampreys will be held in a bucket until the area has been surveyed to prevent repeat electroshocking of the same individuals. For activities d), e), and f), individuals will be handled with care and given time to recover before being released. The effects of all activities on critical habitat and residences are considered to be negligible. c) Activities are not anticipated to jeopardize survival or recovery of the Vancouver Lamprey. The activities will employ best methods developed to date for the collection of individuals. Activities are anticipated to inform research on knowledge gaps required for the recovery of the species.
