Regional or Local Number: DFO-18-PPAC-00015

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-18-PPAC-00015 is issued.

Purpose:
Scientific research for the conservation of the species

Description:
This permit will apply to the DFO Science Lead Investigator for satellite tagging of Basking Sharks either caught incidentally during a DFO Science research vessel (RV) survey or encountered based on sightings reported by members of the general public. The Lead Investigator has previous experience tagging sharks with satellite and conventional tags. The Lead Investigator is the head of the DFO Canadian Pacific Shark Research Lab and is a member of the Basking Shark Recovery Planning Team as well. Satellite tag information can provide long-term monitoring of a Basking Shark individual—with indication of death or changes in residency. Tagging locations will be within Pacific Canadian waters. For reported sightings, exact coordinates will depend upon where the reported locations are. Each shark encountered will be affixed with a single WC-MINIPAT 1XAA Argos-linked Pop-Up Archiving tag (Wildlife Computers©), inserted into the muscle to one side of the dorsal fin, perpendicular to the fin. Tagging will be carried out from a distance of up to 11’ using a specially designed shark tagging pole with a 6’-11’ telescoping handle and a Wilton dart applicator pin, 1/8” round. Each tag will be programmed to pop-off at a desired time (12 months maximum duration), at which time archived information (i.e. depth, temperature, ambient light levels through which location can be derived) will be available through the Argos- satellite system and CLS America. In the case of an incidental sighting aboard an RV, provided a trained scientist is aboard and the gear is available, tagging will be carried out right away. In the case of reported sightings of Basking Sharks, vessels/ platforms will be deployed in an attempt to locate and tag the shark, dependent upon if the shark can be reached in a timely manner. DFO 25 ft Lifetimer Vessel (Pallasi) CFV C06380BC, or another DFO registered vessels as available, will be utilized.

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Pacific Ocean

Affected Species:

Pre-Conditions:
a) Alternatives: Impacts on the listed species are unlikely. There are no alternative methods for obtaining the desired information. b) Measures to minimize impact: Impacts on the listed species are unlikely. Previous studies have indicated that disturbance to sharks – including Basking Sharks – by the tagging procedure itself is negligible. There is little chance of negatively impacting or harming the shark during the tagging procedure, given that the location of tagging on the body of the shark is far from any vulnerable organs. The tagging gear has also been used by other researchers, with no detectable negative impact on Basking Sharks. Studies have also indicated long-distance movements/ migrations by sharks carrying satellite tags, indicating little (if any) behavioural modification as a result of being tagged and/or carrying a tag Animal Use Protocol (AUP) authorization has been obtained for tagging activities. Only trained DFO employees will be involved in tagged activities for located shark(s). c) Effects on survival and recovery: Previous studies have indicated that disturbance to sharks – including Basking Sharks – by the tagging procedure itself is negligible. There is little chance of negatively impacting or harming the shark during the tagging procedure, given that the location of tagging on the body of the shark is far from any vulnerable organs. Studies have also indicated long-distance movements/ migrations by sharks carrying satellite tags, indicating little (if any) behavioural modification as a result of being tagged and/or carrying a tag.

Other Relevant Information:
Tagging of Basking Sharks is identified as a high priority for scientific research to be undertaken by DFO for Basking Sharks as per the proposed Basking Shark Action Plan (in press. 2018). Opportunistic satellite tagging will be carried out in order to: 1. Provide information on species distribution within Pacific waters, including Canadian waters, so that critical habitat might be delineated in the future. 2. Provide information on the residency (or philopatry) of basking sharks within Canadian Pacific waters. 3. Provide information on the seasonal movements/ migratory patterns of basking sharks within and outside of Canadian Pacific waters.
