There isn't one umbrella organization representing licence-holders in Nova Scotia, but there are several that are quite large and that represent multi-licensed enterprises. The Eastern Shore Fishermen's Protective Association and the Grand Manan Fishermen's Association do represent multi-licensed enterprises.
In the case of southwest Nova Scotia in particular, I can speak to groundfish quite knowledgeably. They do have the community management boards, and the department does require the community management board to be registered under the Societies Act. As a result, they are required to have annual general meetings at which they elect their representatives. Those are the representatives who come forward to represent industry at the advisory committees.
