Alosa macedonica Alosa macedonica Alosa macedonica, or the Macedonian shad (also known as "liparia"), is a landlocked species of clupeid fish endemic to Greece. Its single natural occurrence is the freshwater Lake Volvi in northern Greece. It is threatened by habitat loss. "Alosa macedonica" is a member of the "Alosa" genus, whose other species are often anadromous migrating between marine and freshwater. Research suggests that the ancestors of "Alosa macedonica" inhabited marine regions of the Aegean Sea. "Alosa macedonica" have teeth in the palatine and vomer. They have approximately 50 vertebrae and 106-128 gill rakers. They are about 181-230mm in length and
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").
