The 1.4 kilogram female (three pounds) crustacean came up in a trap on July 21 on Mutton Bay, a protected inlet off the Gulf of St. Lawrence, in the municipality of Gros-Mécatina.
Lloyd Green, the fisherman who caught her, has named the lobster "Blondie." He has been feeding her herring to help her gain weight.
The mayor of Gros-Mécatina, Randy Jones, said while he loves to eat lobster, this is one he'd like to see survive.
"I'd like to see the lobster, and I think the fisherman would too, in an aquarium somewhere where people could look at it and see that there is such a thing as white lobster," Jones said. "It's a bit of promotion for the Quebec Lower North Shore, also."
The Quebec City aquarium has told Jones it will make a decision shortly.
If Green has to keep Blondie past Aug. 15, he will require a permit from the Department of Fisheries and Oceans.
