OTN/DFO Maritimes Spiny Dogfish Tagging

To determine if spiny dogfish remain in Canadian waters or if they cross over the US/Canadian border to American waters. The results would have an effect on the joint management of the dogfish fishery between Canada and the US and help determine the contribution spawning females have to the NW Atlantic metapopulation of dogfish. The data would help with future management of the fishery as well as future discussions with the US.

This OBIS product reports the tagging/release of these dogfish. Though there have been detections by OTN (Ocean Tracking Network) acoustic receivers, these are currently being used for in-progress research.

This dataset is the OBIS version of the spiny dogfish tagging. These data are for display on the OBIS portal and associated mapping programs and for download for end-user analysis.
