About

Freshwater bass are a group of North American fish in the sunfish family. In this app the group includes the Largemouth Bass, Bluegill, and Pumpkinseed.

How to tell it apart

Look for a dull-green body with dark side markings and a stocky, sunfish-like shape. Tell the members apart by size and how bold or broken the dark pattern is.

Appearance

These fish have a dull green body with dark patterns on the sides. Most grow to 40-60 cm, though some Largemouth Bass reach almost a metre.

Habitat

This group lives in freshwater across North America, from the Hudson Bay basin in Canada down to northeastern Mexico. Some species have been introduced to freshwater around the world.

Behaviour

These fish are popular with anglers and fight hard when hooked. In many places outside their native range, they have become invasive and harm local ecosystems.

Breeding

In the breeding season, the male builds a nest on the lake or river bed. The female lays her eggs there and the male fertilises them, then guards the eggs and young fish until they leave the nest.
