Smallmouth Buffalo

Smallmouth Buffalo are native Louisiana fish in the sucker family (Catostomidae), not the minnow family like carp despite their similar appearance.
These long-lived fish can survive over 40 years and are found throughout Louisiana's large rivers and lakes, being most common in the Mississippi River system and major tributaries.
Scientific Name: Ictiobus bubalus
Also known as razorbacks
- Distinguished by their deep, laterally compressed bodies with high-arched backs, they have small downward-pointing mouths located beneath the snout (subterminal), large eyes, and lack the barbels found on carp.
- Their coloration ranges from bronze to gray-brown with a distinctive greenish tinge on the upper sides and back.
- Louisiana specimens typically reach 16-24 inches and 6-8 pounds, though they can grow much larger with some reaching 35+ inches and 50+ pounds.
- They're commonly called 'razorbacks' due to their narrow, high-arched profile when viewed head-on.
