Brook Trout
Also known as a "brookie," the brook trout is regarded as the principal game fish in parts of New England although it is native to northeastern North America from north Georgia to the Arctic Circle.  It is distinguished by red spots with blue aureoles on the sides, dark wavy lines on the back and dorsal fin, pink or reddish lower fins edged with white on the leading edge, and teeth on the head of the vomer.  The name "squaretail" is sometimes applied to the brook trout because its caudal fin is only slightly forked or square.  All of the brook trout's fins are softrayed, the dorsal fin having 10 rays and the anal fin nine rays.  The body is about five times as long as it is deep, and its preferred temperature range is 57.2-60.8 degrees Fahrenheit.  The brookie feeds mainly on insects, crustaceans, mollusks and fish.
