Marine use of Atlantic sturgeon in the Gulf of Maine

Atlantic sturgeon in the Gulf of Maine use freshwater habitat in the summer to spawn and feed before moving back to the marine environment. Patterns of marine habitat use are poorly characterized and this represents a conspicuous gap in knowledge of critical habitat use for these threatened/endangered fish. We sought to use satellite tags to track fish from the Kennebec and Penobscot Rivers in Maine to identify areas of marine use.
