  • Bowfin can be quite effective in keeping populations of other fish species in check.

Range / Habitat

  • Bowfin occurs from the Mississippi River drainage eastward to the St. Lawrence River and south from Texas to Florida.
  • Found in sluggish waters, swamps, sloughs, pools and backwaters of lowland streams, usually near rooted vegetation.

Additional Information

  • This species has a number of common names used locally, including “dogfish,” “mudfish,” “grindle,” “prairie bass,” “cypress bass,” “cypress trout,” “cottonfish,” “scaly cat” and “mudjack.”
  • Bowfin is a very primitive fish and therefore is often referred to as a “living fossil.”
  • Its swim bladder functions as a lung that enables it to live in oxygen-poor waters. In extreme conditions, it can live out of water for a day as long as its body and gills remain wet.
  • In parts of the South, the eggs of this fish are marketed as caviar, specifically, “Choupique Royale.”
  • Though not considered a sport fish, bowfin will take a hook and are considered strong fighters on light tackle.
