8.1.3 Project description
Critical habitat for Atlantic salmon (Gulf of Maine DPS) includes the stream channels within the designated stream reaches, and includes a lateral extent as defined by the ordinary high-water line (33 CFR 329.11). In areas where the ordinary high-water line has not been defined, the lateral extent will be defined by the bankfull elevation. Bankfull elevation is the level at which water begins to leave the channel and move into the floodplain and is reached at a discharge which generally has a recurrence interval of 1 to 2 years on an annual flood series. Critical habitat in estuaries is defined by the perimeter of the water body as displayed on standard 1:24,000 scale topographic maps or the elevation of extreme high water, whichever is greater.Watershed boundaries provide a standard level of detail that is an acceptable unit to describe salmon habitat, and the watershed level 5 (HUC 10s) are nationally recognized by the USGS to spatially relate any dataset that contains these codes.

8.5.3 Project description
The U.S. Atlantic Salmon Assessment Committee (USASAC) coordinates the annual assessment of Atlantic salmon in New England rivers and reports to the North Atlantic Salmon Commission (NASCO) on the status of the species. As part of the USASAC, Northeast Fishery Center staff manage the database for which the annual report to NASCO is based. These data include historic salmon rivers, number of returning adult salmon, estimates of escapement, numbers of salmon stocked, egg production, and marking/tagging of salmon. The USASAC database takes raw data, runs them through a series of many queries, formats query results, and displays them in several report tables which are included as appendices to the annual USASAC report to NASCO

8.6.3 Project description
Sturgeon investigations have been conducted in the Merrimack River by the Conte Anadromous Fish Research Laboratory, Turners Falls, Massachusetts. Studies beginning in 2008 follow initial efforts in 1987-1990, the first documentation a reproductive shortnose sturgeon population still inhabited this river. The current studies, initiated as part of a range-wide genetic evaluation effort, has determined a significant population increase among shortnose sturgeon as well as an annual coastal spawning migration to the Kennebec River. All efforts in the Merrimack River are part of the Gulf of Maine Sturgeon Research Collaboration, including investigations by the University of Maine, Orono (Penobscot River), the Maine Department of Marine Resources, Augusta, Maine, the New England University, Biddeford, Maine (Saco River), and the Conte Anadromous Fish Research Laboratory, Turners Falls, Massachusetts. Cooperation is also received from the Portsmouth Naval Shipyard, Kittery, Maine.

8.8.3 Project description
NEAMAP (Northeast Area Monitoring and Assessment Program) is a collaborative state-federal initiative dedicated to the collection, analysis, and dissemination of fishery-independent data along the Atlantic coast, from the Gulf of Maine to Cape Hatteras, NC. Our data collection efforts support stock assessments and fisheries management while enhancing our understanding of the marine ecosystem. The fishery-independent data we gather are invaluable resources for government agencies, recreational and commercial fisheries, researchers, and various stakeholders. Our program aims to coordinate existing fishery-independent surveys to optimize activities, promote comprehensive and consistent data collection, and maximize the utility of survey findings.

8.9.3 Project description
The Saco River Estuary support several species of migratory fishes. The goal of this study is to determine the seasonal movement and habitat use of Striped Bass and Atlantic Sturgeon in the Saco River. Using acoustic telemetry, this study established a network of passive receivers to better understand Striped Bass seasonal movements in the Saco River, and throughout their coastal migratory range. The Gulf of Maine Distinct Population Segment of Atlantic Sturgeon are listed as threatened. Atlantic Sturgeon utilize the Saco River as a feeding ground, but move among nearby rivers. Characterizing seasonal presence and connectivity of Atlantic Sturgeon among Maine Rivers, is essential to better understand dynamics of threatened populations. Fish are internally tagged with V13 or V16 acoustic tag. Receivers are located throughout the Saco River and Saco Bay and deployed from June to November.

8.10.3 Project description
This project would use existing acoustic telemetry data compiled for Atlantic sturgeon from the Atlantic Cooperative Telemetry (ACT) Network and federally funded projects. Genetic assignment data will be generated by USGS using the latest baseline for the species, leveraging existing genotype data (874 telemetered individuals) and additional samples collected for this study. Synthesizing this information, DPS-specific migration maps will be generated showing the seasonal patterns of Atlantic sturgeon occupancy along the Atlantic coast. Spatial and temporal occurrence data from the telemetry data would be divided by DPS and life-history stage. This information would then be compared to the location of proposed offshore wind energy projects to help characterize relative risk of projects to different DPSs and life history stages of Atlantic sturgeon.

8.15.3 Project description
The Maine-New Hampshire Inshore Trawl Survey is a fishery-independent survey operated by Maine Department of Marine Resources that started in the fall of 2000. The survey is a collaborative partnership between commercial fishermen and state researchers to assess inshore fish stocks along the coast of Maine and New Hampshire. The survey occurs twice a year, in the spring and fall, and covers about 4500 square miles.
