Gulf of Maine Responsibly Harvested Haddock Criteria: The fishery is managed by a competent authority and has a management plan in place that incorporates a science-based approach to ensure sustainability. Haddock stocks in the Gulf of Maine region are managed separately according to where the fish is harvested. The Gulf of Maine (GOM) and Georges Bank (GB) haddock stocks (Fig. 1) are managed by the National Marine Fisheries Service (NMFS) and the New England Fishery Management Council (NEFMC), under the Northeast Multispecies Fishery Management Plan. Haddock harvested in Gulf of Maine region’s Canadian waters (Fig. 1 and 2) is managed by the Canadian Department of Fisheries and Oceans (DFO), through the Scotia-Fundy Groundfish Management Plan. Because haddock stocks can extend across international maritime boundaries, some eastern GB haddock is managed jointly by the U.S. and Canada. These management bodies apply the best available science to determine the harvest levels that result in healthy stock sizes and long-term viability of the resource. Criteria: If stock sizes are below management target levels, whether due to natural or man-made causes, management plans are established that enable rebuilding within a specified timeframe. GOM and GB haddock stocks are considered fully rebuilt by NMFS. Canadian haddock stocks in the northern region of the Gulf of Maine are currently above target levels with fishing effort being managed to prevent the stocks from reaching unsustainable levels. Harvesting of Canadian haddock stocks in eastern Georges Banks is also well regulated in relation to stock size, resulting in a healthy fishery. Criteria: Sufficient data exists to determine harvest levels. Harvest levels for the GOM and GB haddock are set in the form of Annual Catch Limits (ACLs) by the New England Fishery Management Council. Surveys and landings data are some of the types of information used to determine ACLs. Managers also account for uncertainty in data when determining appropriate harvest levels for haddock. Similar data is used by Canadian managers to determine harvest levels, or Total Allowable Catch (TAC,) of Canadian haddock. The TAC of the trans-boundary haddock stock is determined through a collaborative effort between Canada and the US. Criteria: Monitoring and compliance measures are in place to ensure acceptable harvest levels. Haddock caught by U.S. vessels in the Gulf of Maine region is monitored through vessel trip reports (VTRs), observers, dealer reports, dockside monitoring, electronic reporting, and field enforcement. These efforts ensure compliance with regulated harvest levels. The harvest of haddock in Canada is assessed through dockside monitoring, at-sea monitoring, and electronic vessel monitoring systems. These tools are used to track landings and monitor compliance of harvest levels. Criteria: Enforcement exists to ensure that harvesters follow regulations, and to prevent illegal practices and unreported harvest. The U.S. Coast Guard, NMFS Office of Law Enforcement agents, and state marine patrol agents enforce the laws and regulations governing the harvest of GOM and GB haddock. In Canada, DFO through regular patrols is responsible for enforcing haddock management regulations.
