I've written a number of posts on the influx of marine life into our local waters around Vancouver Island. It's like the entire food chain has shifted north, away from the warming Pacific waters to the south. It begins with bigger schools of herring and the arrival of sardines. As the prey fish migrate so too do their predators. As a result we've seen large increases across the board from prey fish to schools of dolphins, transient orcas, seals and sea lions, various once rare fish species, even pelicans.
Not surprisingly, Eastern Canada is witnessing the same thing. CBC News reports there's been a big uptick of marine biodiversity in the St. Lawrence River. Again it seems that the migration of prey fish, in this case capelin, may be the proximate cause.
[Quebec marine biologist Lyne Morisette] said observers have spotted more capelin than in summers past. Capelin are small fish that serve an important role in the ecosystem, feeding whales, seals, cod and sea birds.
She said in some places off the Gaspé coast, there are so many capelin that if you take a bucket out into one foot of water, you could catch a few.
"All species will adapt to that, either physically [to] be able to live in the warmer environment, or they'll move somewhere else" and be replaced by warm-water species moving north, she said.
Even Maine's vaunted lobster fishery is being hammered by warming waters. Fishermen there are coming up empty-handed as the lobsters are migrating into cooler Canadian waters.
This should be a warning to the world that climate change is upon us and it's coming on faster than we had imagined. There's no hoax behind the migration of fish, marine mammals and seabirds. They do pretty much as they like and we're damned fools if we don't heed their warning.
