At a brand new discipline station on an island off Nova Scotia’s South Shore, researchers try to fill within the gaps about white sharks off Nova Scotia.
From the Tancook Islands Marine Subject Station on Huge Tancook Island, a workforce of a dozen graduate and undergraduate college students use an array of monitoring applied sciences to observe white shark motion. The workforce is led by Nigel Hussey, a professor of integrative biology on the College of Windsor in Ontario.
Final 12 months, of their first 12 months of operations, they tagged 16 white sharks off the coast of Nova Scotia. The 2026 tagging expedition launches this weekend.
The sphere station has additionally launched their very own tracker, the place the general public can observe the sharks tagged by the sector station in 2025, plus any of the sharks they tag in 2026.
However the station’s founder mentioned that work is sophisticated by Canada’s allowing system for working with the animals.
“I believe in the intervening time we do not have the capability … set as much as cope with white sharks in Atlantic Canada,” Hussey mentioned. “We have to fairly rapidly … get these organizations in place.”
The Tancook Islands Marine Subject Station was began by Hussey and his spouse, Anna, after Hussey joined a tagging expedition run by the group Ocearch in Atlantic Canada in 2018.
On the time, Hussey thought it was unlikely they’d discover sufficient sharks to make the expedition worthwhile. Although there had been information of white sharks in Atlantic Canadian waters going again over a century, they had been uncommon.
“I mentioned on the time, ‘You realize, that is like discovering a needle within the haystack,’” mentioned Hussey. “However after all I used to be proved fully mistaken.”
That sparked an thought to determine a analysis base in Nova Scotia from which to check the animals whereas they’re within the area.
Hussey mentioned in the intervening time, unknowns embrace whether or not there are migration corridors, the place sharks congregate, their inhabitants measurement and their influence on the ecosystem.
The sphere station seeks to reply these questions with several types of tags, together with satellite tv for pc tags.
Utilizing a brand new satellite tv for pc system launched final summer time, Hussey mentioned these strategies are beginning to present a greater image of white shark motion. With this new information, he expects that by the tip of the summer time, they’ll be capable to present a preliminary evaluation of white shark sizzling spots in Atlantic Canada.
‘It creates challenges’
But Hussey mentioned the allowing system makes it difficult to undertake this work.
As a result of white sharks are listed federally as an endangered species, scientists require a particular allow from Fisheries and Oceans Canada to work with the animals.
Permits must be utilized for yearly, and within the weeks main as much as his 2026 expedition, the allow had but to reach.
“It creates challenges on the logistics facet,” he mentioned.
Hussey can also be involved with the way in which permits cowl folks doing totally different actions, together with business cage diving, wildlife documentary manufacturing and strictly scientific analysis.
“This one-size-fits-all does not work as a result of the precise wants for the permits are extraordinarily totally different.”
A brand new discipline station on Nova Scotia’s Huge Tancook Island helps monitor Atlantic Canada’s white shark inhabitants. The CBC’s Moira Donovan visited the distant station to study extra.
For example, Hussey cites a allow situation that limits scientific analysis to the open ocean — though white sharks usually hang around nearer to shore.
“The animals are simply not on the market, in order that boundary line may be very sophisticated on effectivity and logistics.”
Hussey mentioned these limitations throughout the permits make it sophisticated to determine the sort of long-term monitoring program that’s wanted to grasp white sharks in Atlantic Canada.
In an announcement, DFO spokesperson Christine Lyons mentioned the division assesses functions on a case-by-case foundation and that selections are usually made inside 90 days.
Lyons mentioned the division has “utilized and communicated clear and constant standards for the way and the place permitted White Shark analysis actions can happen primarily based on the most effective accessible data and utilizing a precautionary method.”
Subject station ‘a blessing’ for Tancook
Once they do have their permits in place, Hussey mentioned the station may also help nurture the following era of scientists — however he hopes the advantages gained’t cease there.
David Baker, a lifelong lobster fisherman and fourth-generation Tancook resident, has been serving to the sector analysis workforce set out their community of practically 80 acoustic receivers alongside the coast in the summertime and choose them up within the fall.
Baker mentioned having the sector station has been “a blessing” for the group, and a boon for the wharf, the place the variety of fishermen has declined over time.
“There’s much more [sharks] right here than what we thought,” he mentioned. “You’ve acquired to have the science to associate with it and I am simply completely satisfied to be a small a part of that.”
Hussey mentioned they plan to broaden the sector station by opening an training centre the place the general public can study extra about sharks. Long run, that might additionally play a job within the island’s future.
“The entire level was that that is a part of the group,” he mentioned. “It’s a manner we evolve right here on the islands and may doubtlessly assist assist financial development sooner or later.”
