White Sturgeon








White Sturgeon [Acipenser transmontanus] The Largest of American freshwater fish. White sturgeon weighing over 1200 lbs have been recorded in recent history. Long rows of white armor spikes make this an easy to distinguish species. These spikes are located at the lateral and dorsal lines and run the length of the body starting from behind the gill plates back to the tail. You may note a large sucker type mouth when observing sturgeon. Also note that the large dorsal fin appears to be located behind the pectoral fin. Skin appears silver [fresh in from ocean travel] to dark green [river resident] depending on location. See photos~
