Tunicates create 'a lot of work' at D’Eon Oysters, which produces 1.4 million oysters annually. Lucas Wood and Nolan D’Eon on Eel Lake in southwestern Nova Scotia. They'll spawn twice in a season, so you have two cohorts in one year and there's just billions of the things." "Scraping tunicates off mussels is my life," joked Peter Darnell, a veteran mussel and scallop farmer in Mahone Bay, N.S. They don't die over the winter, which is a lot more work for us," D'Eon said. Now you lift up your cages and they're all alive. And they used to all turn green in the winter. "We have a spawn of tunicates at a time that we've never had before. His solution is to flip each cage upside down for 48 hours and let sun and heat kill the tunicates - but they always come back. But we don't ever let them grow," D'Eon said as he recently examined an oyster cage pulled on board a service boat at a site in Eel Lake. They're very, very small as of right now. Tunicates are now a year-round fact of life for Nolan D'Eon, who produces 1.4 million oysters annually on his farm in Argyle, N.S. The wharf is one of dozens of monitoring sites for sea squirts or tunicates. The invasives arrive primarily on vessel hulls and in ballast water discharge.įisheries and Oceans research scientist Claudio DiBacco and technician Neo Paulin at the Digby, N.S., wharf. When poked or prodded, they shoot water from a siphon - hence the name, sea squirt. Tunicates are a sack full of organs and water that are adept at filtering food, reproducing and "biofouling" - accumulating on everything from boats to underwater pipes. "There's no doubt in my mind that most of these species are here because of the warming climate," said Claudio DiBacco, a federal research scientist specializing in aquatic invasive species at the Bedford Institute of Oceanography in Dartmouth, N.S. The creatures cling to anything they come into contact with and have become a major problem in the shellfish aquaculture sector. They are 95 per cent water and heavy, weighing down ropes and increasing shear stress during storms and the risk of lost gear and product. Six invasive sea squirt - or tunicate - species have become established in Nova Scotia in the last decade. Don't wipe it off, and let it dry completely before your ride.Scientists are monitoring dozens of sites in Nova Scotia and southern New Brunswick to see if the latest warm winter in Atlantic Canada accelerated the spread of slimy marine invertebrates.
