I do believe those are actually crayfish (edit: yes, checked, and they are 100% one of the ones being banned), and I think are now contraband where I live lol they just put up a new law coming into effect come Jan 1st 2024 for two genus of crayfish plus a bunch of other stuff, including ALL kinds of salvinia. Will be totally prohibited to possess it at all, sell, etc.Maybe it's a myth Did New England prisoners really eat lobster in colonial times? (boston.com)
There are freshwater blue lobsters sold for tanks...5 inches
Sigh. Gotta burn all my salvinia new years eve.
You mean these, yes?

Procambarus genus is prohibited in my province starting the new year.
