Rachel Carson National Wildlife Refuge have extensive vernal pool habitat that would benefit several Species of Concern. Coastal marshes, bays, tidal creeks, and rivers support diverse shellfish and finfish populations. Sunfish ("Lepomis" species), creek chub ("Semotilus atromaculatus"), cunner ("Tautogolabrus adspersus"), golden shiner ("Notemigonus crysoleucas"), common mummichog ("Fundulus heteroclitus"), American eel ("Anguilla rostrata"), and white sucker ("Catostomus commersoni") abound. Brook trout ("Salvelinus fontinalis") and brown trout ("Salmo trutta") are stocked in rivers and estuaries each year. The Ogunquit River sustains alewife ("Alosa pseudoharengus"), blueback herring ("Alosa aestivalis"), pollock ("Pollachius virens"), bluefish ("Pomatomus saltatrix"), longhorn sculpin ("Myoxocephalus octodecimspinosus"), and winter flounder ("Pleuronectes americanus").
