Green Sunfish

Green Sunfish

Green Sunfish are common statewide in Kentucky, inhabiting virtually all types of water bodies with remarkable adaptability.

They're extremely tolerant of extremes in turbidity, temperature, dissolved oxygen, and flow conditions, reaching greatest abundance in small sluggish streams and ponds where few other sunfish occur.

Scientific Name: Lepomis cyanellus

Physical Characteristics:
  • These robust sunfish have larger mouths than most sunfish species, with the upper jaw extending to about the middle of the eye.
  • Adults typically grow 8-10 inches, though they can reach up to 12 inches and 2 pounds.
  • They're distinguished by a large black spot at the rear of the soft dorsal fin and yellow to orange margins on their soft dorsal, anal, and caudal fins.
