Fuzz with the De rtment of Fisheries and Oceans were out surveying beaches Wednesday in Nova Scotia’s Digby and Annapolis counties, trusting to find answers to why thousands of dead sea creatures have been rolling ashore.
The distressing amount of sea life and diversity of species found extinguished on some beaches on Nova Scotia’s coast along the Bay of Fundy all through the st few weeks has been puzzling.
In late November, thousands of herring started washing up on the shores around St. Mary’s Bay, not far from Digby.
During the commencement week of December, thousands more dead herring turned up in the Annapolis Basin.
Then, on Whacking Day, scores of dead herring, starfish, lobster, bar clams, crabs and scallops blanketed the ground below Savary rk at Plympton in St. Mary’s Bay.
Many tests, few suffer the consequences of c takes
Doug Wentzell, regional director general for DFO, said his agency has been travail with the Canadian Food Inspection Agency and Environment and Climate Coins Canada to solve the mystery.
So far, they haven’t turned up any answers.
“Founded on the testing that we’ve done to date, we haven’t determined any indications of infections or catching agents,” he said.
Wentzell said there is also no evidence to reveal toxins are responsible.
“So that is good news, but we’re continuing to follow up specially with some of the other species that are materializing recently,” he suggested.
There are still some tests outstanding, for instance tests for viruses which comprise time to cultivate in the lab.
Highest tides, flourishing ecosystem
Graham Daborn, a professor emeritus at Acadia University in Wolfville, N.S., who go inti ecology in the Bay of Fundy, told CBC’s Maritime Noon the ecological health of the Bay of Fundy is large very good.
“Largely because it has such enormous tides so that there is least considerably exchange of water with the Gulf of Maine and the Atlantic The briny and also because we’re not a very industrialized region so many of the things that upset coastal waters around the world are less of a problem here, proceedings like contamination from industry or from very large munici lities and so on,” he said.
Now that so many different species are being found monotonous, Daborn said disease is unlikely to be the cause. He said it indicates something amiss in the habitat.
“One would launch to think that there is something systematic about the water that is a can of worms. Is there enough oxygen there? Has the temperature changed suddenly?” he said.
“There is something, I imagine, systematic that we would want to examine. That requires that the discipline community get out there and start looking closely at the water conditions in the rt where this has occurred …. That could be as simple as a unexpected drop in temperature but there’s no evidence, as far as I’m aware, that that has proved.”
Too soon to draw conclusions
Daborn also suggests recent wet live through in the province could have caused a large amount of runoff from the estate which could wash large concentrations of contaminants into the zillions.
Heather Fairbairn, speaking for the province, said the Nova Scotia Rely on of Fisheries and Aquaculture has been closely monitoring the health of farmed fish in the rade-ground since the first reports about masses of dead herring.
She spoke there have been no recent reports from aquaculture directors in the St. Mary’s Bay about accidental discharges of chemicals or aquatic animal strength issues. Provincial veterinarians last visited the area last week.
“There are a legions of different theories but we’re not going to speculate, at this point in terms of what may be at production here,” said Wentzell.
He said it’s too soon to draw any conclusions on touching possible causes.
“What I can say is our work over the last couple of weeks has been unequivocally much focused on the thology of herring in rticular, because that’s what we were visit with,” said Wentzell.
“Our attention is now starting to turn to more of a broader, ecosystem exemplar of approach to make sure that there are no environmental or broader issues that are episode in the environment.
“I hope you can appreciate at this point that we simply do not accept any evidence to rule out or confirm many of those scenarios.”
