The hybrid bluegill is a popular sporting fish. As noted by Kentucky State University, a hybrid bluegill is a cross between a male bluegill and a female green sunfish.
Fingerlings, or small fish, can grow to be approximately two to three inches. It takes two to three months to reach this size.
Annual Growth Rate
Hybrid bluegills can grow at a rate of one-half to three-quarters of a pound per growing season, according to Dunn's Fish Farm. Faster growth rates occur with colder water temperatures and adequate food supply, such as insects and smaller fish.
At maturity, hybrid bluegills can reach two to three pounds. Occasionally, hybrid bluegills can grow larger than three pounds.
