Halifax — Scientists will begin probing waters off Nova Scotia in search of a slimy creature they believe is slithering north and could be blanketing some of Canada's richest fishing grounds.
The creature, which measures one to two millimetres individually, attaches itself to rocky bottoms and proliferates rapidly until it creates a sometimes huge carpet that can come between various fish species and their food.
The fear is that it could also interfere with the scallop fishery, one of the most vibrant and lucrative on Georges Bank, by disrupting the resting ground for scallop larvae.
“The implication is that if this organism was limiting space for larvae to settle, then that would limit the amount of habitat for these larvae and that would not be a good thing,” said Dr. Valentine.
It's not clear how much of a threat the unique life form poses to lobster, herring, swordfish, groundfish and tuna stocks, but it could be difficult to slow or control since it has no known predators.
