Haddock, Melanogrammus
aeglefinus,
is a member of the gadoid family. It is a cold water groundfish that
ranges from Greenland to Cape Hatteras. Spawning occurs between
January and June,
depending on the temperature of the water where the adults
reside. Haddock have a distinct black "thumb print" above
the pectoral fins and are very popular as a food fish.

Tautog, Tautoga
onitis, is one of two labrides that do not
live in a warm, reef like habitat. Tautog can be found from
Nova Scotia to Georgia. Spawning occurs from early June through
August. Tautog is very structurally oriented fish and is
normally found in areas with cover and structure at all life
stages.
Tautog is a popular recreational and commercial fish.
Black sea bass
Basic color is dark brown or black. Head is bluish-black to dark
brown. Dorsal fin has rows and stripes of white on black; large
males have iridescent blue and ebony markings, and fatty hump in
front of dorsal fin; females may have indistinct vertical barrings;
topmost ray of caudal fin much elongated in adults; caudal may
be tri-lobed; sharp spine near posterior margin of gill cover.
Adult males are entirely blue-black except for white areas on the
head and edges of the fins. This is a warm-temperate species ranging
from Maine to northern Florida and a somewhat distinct population
in the eastern Gulf of Mexico.
Winter Flounder
Winter flounder's name derives from its tendency to move
during the winter months to shallower inshore waters. It
ranges from southern
Labrador to the waters of South Carolina and Georgia and is
most abundant from the gulf of St. Lawrence to the Chesapeake
Bay.
It is frequently called "blackback" when it is smaller than
3 pounds and "lemon sole" when it is larger. Like
all flat fish, the winter flounder has both eyes on one side
of the
head. The winter flounder is referred to as a right-handed
flounder because the eyes are located on its upper surface
when the fish
is pointing to the right. Female winter flounder grow faster
than males and attain a maximum size of about 8 pounds, with
a length
of 25 inches. They may live up to 15 years.
