Pennsylvania Symbols, State Fish: Brook Trout

Adopted on March 9, 1970.

There is nothing more beautiful than the flash of a Brook Trout beneath a bubbling current — especially for Pennsylvania's 1.1 million anglers. Over 4,000 miles of cold water streams form the natural habitat of this fish, the only trout native to Pennsylvania.
 

Salvelinus fontinalis or Speckled Trout, Aurora Trout, Brookie, Square-Tail, Speckled Char, Sea Trout, Common Brook Trout, Mud Trout, Breac. The brook trout is of the salmon family. It survives only in clear, cold water and populates the mountain rivers and streams of Pennsylvania.

The average length is 10-12 inches but Brook Trout can be caught measuring up to 21 inches and weighing 4-6 pounds. The largest Brook trout on record was 14.5 pounds and caught in 1916 in the Nipigon River in Ontario. Breeding males develop a hook at the front of the lower jaw. Typical coloring is olive-green to dark brown on the back with silvery sides and pale spotting. All colors intensify at spawning time.
