Can we use fish morphology to reliably differentiate between resident Kennebec spawning striped bass and the migratory population?

Why this matters

Although the majority of stripers along the Maine coast are seasonal migrants from the Chesapeake Bay, there is a small population that spawns in the Kennebec River and stays in the Gulf of Maine. Learning more about each population of striped bass in Maine is essential to informed management of this fishery.
