There are a small number of them. There are some that are provincially run and there are some that are a mix. They fall into multiple categories. Their administrative structure is such that it's very difficult to say: here is the standard approach; it looks like this. There is quite a mix of them.
In all cases, though, before they can introduce fish into the water, they require an introductions and transfers permit from the Department of Fisheries and Oceans under section 56 of the fishery's general regulations, so they have a common licence point, if you will. Under the new regime they will all require an aquaculture licence, which will replace that introductions and transfers licence and put them under a single, homogeneous regulatory regime.
