Kind of looks like one, here is a link to some info on the chain pickerel. I know they tend to be on the skinny side.

and here is a little info on the fish:
Distribution
The chain pickerel is limited to eastern and south-central North America, south from Colchester County, Nova Scotia, east of the Allegheny-Appalachian mountains, to central Florida, west to eastern Texas, and north to Missouri and the Tennessee River system in Alabama.
Although it is normally a freshwater fish, it has been known to find its way into brackish (salt) waters in the eastern and Gulf states. In Canada it occurs only in Nova Scotia, western New Brunswick, and the Eastern townships of Quebec, south of the St. Lawrence River. It was introduced in Nova Scotia and can be found in Digby and Yarmouth counties and as far east as Hants and Colchester counties.
Physical Characteristics
The chain pickerel has the following characteristics:
a long, narrow body;
the fish gets its name from the chain-like pattern on its sides;
the adults are coloured bright green, through olive-green to nearly brown on the back and upper sides; its sides are prominently marked by yellow-green to yellow areas broken by dark, interconnecting markings resembling links of a chain;
the young are bright green through brown to almost black on the back, with a pronounced golden mid-dorsal stripe; the upper sides are bright green to almost black; the chain markings do not develop until the fish is about 6 to 8 inches in length;
the average length is 15 to 20 inches (38.1 to 50.8 cm);
its head is long, flat, and naked on top and somewhat concave between the eyes, which are high on the head and moderately large; the pupil of the eye is yellow and its mouth is large with small hook-like teeth set in the roof of its mouth and long canines at the sides;
it has a long snout which is 44 to 48 per cent of its head length;
the lower jaw is slightly longer than the snout;
it has one dorsal (back) fin; the caudal or tail fin is long and deeply forked; pelvic fins are present;
the lateral line is complete.
