Largemouth Bass vs Smallmouth Bass

 

Be Alert!  

Largemouth bass have recently been caught in Grand Falls Flowage (St. Croix River). Their presence is believed to be due to an illegal introduction. The New Brunswick Department of Natural Resources and Maine Department of Inland Fisheries and Wildlife encourage all anglers fishing in the St. Croix River drainage to keep all sizes of largemouth bass and to report them to the appropriate agency. The continued presence of largemouth bass may have a negative impact on existing fish species and their fisheries. 

 

Identification Tips:

Largemouth Bass

  1. Mouth terminates behind the eye

  2. Separation between spiny and soft rays on dorsal fin

  3. Dark horizontal bar

 

Smallmouth Bass

  1. Mouth terminates inline with or slightly ahead of the eye

  2. No separation between spiny and soft rays on dorsal fin

  3. Dark vertical patches
