Aquatic invasive species seems to be the emerging issue in terms of fisheries protection.
In terms of fisheries protection, there are five physical threats to fisheries: overfishing is managed through deciding who gets a licence, etc.; pollution is managed through section 36; water flow is managed through section 20 of the Fisheries Act; habitat is managed through section 35 of the Fisheries Act. As for the invasive species, the changes to the Fisheries Act that we made in 2012 that Parliament passed now give us the authority to address invasive species, and we have a regulation that is currently undergoing formal consultation. What it will do when it is passed, presuming it's put into effect, is ban or prohibit the sale, transport, and possession of aquatic invasive species, and there's a list of what those species are. It will also give ministers, federal and provincial—and territorial if they want it—the tools to eradicate and address aquatic invasive species.
