Diet
The Ruddy Bowfin is a top-level predator in the waters they inhabit. Using a combination of speed, suction, and rows of razor sharp teeth, they prey heavily upon other species of fish.
Distribution:
Ruddy Bowfin are native to Virginia’s coastal plain waters east of the Blue Ridge.
Habitat
Ruddy Bowfin thrive in lazy side-channels and backwaters that have an abundance of cover. Ruddy Bowfin can often be found near submerged structures such as downed trees, stumps, and Cypress knees. They will also utilize undercut banks and submerged aquatic vegetation.
Reproduction
The Ruddy Bowfin spawns in shallow vegetated areas from April to June in Virginia. The male Ruddy Bowfin builds a nest or multiple nests by using their fins to clear away vegetation and create a slight depression in the substrate. Once a female has deposited eggs that the male has fertilized, the male Ruddy Bowfin will defend the nesting site.
