Pumpkinseed - Lepomis gibbosus

Pumpkinseed - Bill Byrne, MA Division of Fisheries and Wildlife

Habitat requirements and life history: The pumpkinseed, often referred to as a "kiver" or "kibbie" in New England, is the most widespread and colorful native sunfish in Massachusetts. Pumpkinseeds inhabit lakes, ponds, slow-moving streams that are cool, quiet, shallow and weedy. They generally favor slightly cooler waters than the bluegill. They feed primarily on insects, but will also eat crustaceans, fish eggs, very small fish and aquatic vegetation. Like all sunfish, pumpkinseeds breed in the spring in shallow, saucer-shaped nests scooped out by the males. Unlike bluegills, which usually concentrate their nests in colonies, pumpkinseeds place their nests in scattered locations. The males round up one or more females and bring them to the nest to lay eggs. After the male fertilizes the eggs, he drives off the female and fans the eggs with his tail until they hatch. He will stay to protect the young until they can fend for themselves. (Sources: Massachusetts Wildlife, No. 2, 2000, Special Fishing Issue and AMC Guide to Freshwater Fishing in New England)
