Bluegill has a range from North America that extends from Canada to Northern Mexico. It occurs in the United States towards the east of the Rocky Mountains. This ranges all the way from Virginia to Florida and west of Texas to northern Mexico. It also ranges from north to western Minnesota and western New York. Bluegill has now been introduced in almost all places in North America as well as Europe, Zimbabwe, South Africa, South America, Asia, and Oceania.
The weed beds are the prime habitat of the Bluegill. They live in the sunken islands, creek channels, and the off deep points. The Bluegills like ponds, quiet streams, and small to medium-sized lakes. They can also stay in the swimming rafts, the shade of the piers, shores that are shaded with trees or stay submerged in the aquatic vegetation. They spawn in the late spring season or in the early summer season when the water temperature is 70 to 75 degrees Fahrenheit.
After spawning, the males will stay in the shallow waters to feed and to roam. In the non-reproductive months, the Bluegill will spend time in water that has a temperate of 60 to 80 degrees Fahrenheit. They stay in schools of 10 to 20 fishes and the school could include other panfish as well.
The Bluegill feed on insects, small crustaceans, insect larva and on worms. They are opportunists by nature. They are not fussy about what they eat.
