Swamp Darter

Scientific name: Etheostoma fusiforme

Identification: Swamp darters are very small, freshwater fish that are about 1.5 inches in length on average. These fish are dark olive in color, and they have a dark lateral line along with splotches on their sides. They have a short snout and a dark bar beneath their eyes.

Habitat: Swamp darters live in vegetated backwaters and along the shorelines. They can reside within large rivers and small streams, but they prefer riverine systems with a sandy or detritus bottom.

Overview: Swamp darters are considered to be a species of concern in New Hampshire, since the populations are declining. Habitat degradation is leading towards extirpation as vegetation is removed and streams are altered. In New Hampshire, populations are restricted to the southeastern corner of the state.
