Green Sunfish
Green Sunfish are an introduced species in Connecticut, most commonly found in the upper Thames watershed and several western coastal streams where they are typically uncommon to rare in abundance.
Their range appears to be slowly expanding throughout the state. These aggressive freshwater fish don't compete well against Connecticut's native sunfish species.
Scientific Name: Lepomis cyanellus
- Have a moderately deep body with a large mouth reaching below the center of the pupil, distinguishing them from other sunfish species.
- They typically measure 3-6 inches, with Connecticut's state survey maximum at 7.5 inches.
- Green Sunfish have dark olive backs fading to greenish-brown sides with about 7 faint vertical bars, aqua-colored wavy lines on cheeks, and characteristic light yellowish margins on soft dorsal, anal and tail fins.
