Lepomis macrochirus Bluegill (Also: Sunfish) Geographic Range. Bluegill was "lost" by a defective range safety tracking radar and had to be destroyed 10 minutes after liftoff even though it probably ascended successfully.  The dorsal and anal fins are two types of median fins that work in parallel to balance torque during steady swimming. at http://www.umich.edu/~bio440/fishcapsules96/Lepomis.html. , The bluegill is most closely related to the orangespotted sunfish and the redear sunfish, but different in a distinct spot at or near the base of the soft dorsal fin. Males construct nests by forming a circular depression four to 24-inches wide and two to six inches deep. As sunfish or "sunnies," bluegills possess the trademark flattened and high physiques of the family. It is a member of the sunfish family Centrarchidae of the order Perciformes. Their name "bluegill" comes from the iridescent blue and purple region on the cheek and gill cover (opercle). Trust me, you need any expensive gear to fish bluegill. However, the shape of the fish makes them hard to swallow. They release eggs and sperm and then start the process again by swimming in circles. They also impact insect populations by eating aquatic larvae. Males make nests in colonies with from 20 to 50 other males in shallow water less than 1 m deep. Because of their size and the method of cooking them, bluegills are often called panfish. ... Bluegill reproduction takes place at the end of the spring and start of the summer. Bluegills have also been found in the Chesapeake Bay, indicating they can tolerate up to 1.8% salinity. They have an enhanced sense of smell. Physical Description Small-mouth, round and flat body, dark spots on gill and dorsal fin, dorsal fin with two lobes, no adipose fin, 39-45 ctenoid lateral scales, 5-9 dark vertical bars on sides, yellow underside, and the tail is slightly forked yet rounded; Spawning Habitat Shallow areas of lakes and ponds with aquatic vegetation The mouth of the bluegill is very small and requires the use of the pharynx to suck in prey. This will make it possible to determine the number of eggs in each spawn and the frequency of spawning. (2019). Prey comes in with this water. Like other sunfish, bluegill have very deep and highly compressed bodies. During summer months, bluegills generally consume 3.2 percent of their body weight each day.  It typically has a yellowish breast and abdomen, with the breast of the breeding male being a bright orange. Accessed The dorsal fin is continuous, with the front part spiny and the back part soft and round with a dark smudge at the base. This is an important game fish in the United States. Sandy or gravel areas are preferred sites. Physical description [edit | edit source] The bluegill is noted for the dark spot that it has on the posterior part of its dorsal fin. In spring and early summer, bluegill can be found on their spawn beds close to shore. , Bluegills play an important role in pond and lake management to keep crustacean and insect populations low, as a single bluegill population may eat up to six times its own weight in just one summer.. If you use too big of a hook the bluegills will just nibble your bait away and you will never set the hook because it’s too big to fit in their mouth. Description of the Sunfish.

The tail fin is slightly forked but rounded. ... Black says it depends on the physical characteristics of the lake, most likely a relation to the depth of the thermocline. They use notched caudal fins, soft dorsal fins, body undulations, and pectoral fins to move forward. The top parts of their bodies are usually blackish-blue, greenish-brown, yellowish-green or deep green, while the rest is generally pale yellow. Bluegill aren't picky eaters. The precise coloration will vary due to the presence of neurally controlledchromatophores under the skin.  The C-start escape response produces other advantages, including the ability to move quickly and unpredictably to capture prey.  Backward swimming in the bluegill is more complex than steady swimming, as it is not just the reversal of forward swimming.  If food is scarce, bluegill will also feed on aquatic vegetation and algae, and if scarce enough, will even feed on their own eggs or offspring. Physical description. During the day they try to remain hidden. 393 pp, Lee, D. S. 1980. Vitamin B-12 is naturally present in only animal-derived foods, and the form of iron in animal-based foods, such as bluegill, is more easily absorbed than the iron in plant-based foods. The name bluegill comes from the Star Trek: Customizable Card Game, but was likely drawn from Riker's description in "Conspiracy" of the blue gill that the parasites had. , The bluegill, amongst a wide array of other fishes, exhibits the C-start escape response, which is generated by large neurons called Mauthner cells. Bluegill are fairly easy to catch and are good to eat.  The dorsal and anal fins' roles as propulsors during escape response suggest that the size of the fins could lead to an evolutionary advantage when escaping predators. The largemouth bass (Micropterus salmoides) could be introduced to control bluegill through predation. A female deposits her eggs into several nests, and a male's nest may be used by several females. Today they have been introduced to almost everywhere else in North America, and have also been introduced into Europe, South Africa, Zimbabwe, Asia, South America, and Oceania. They have a small mouth on a short head.

Physical description Bluegill is one of several "panfish" species in Washington which is very popular across the state because they are easy to catch, they are a great "family fishing activity" and they make excellent table fare. They mostly feed on small aquatic insects and fish. Carlander, K.D. (Murdy, et al., 1997; Williams, 1996), Spawning occurs when water is between 17 and 31 degrees C; in the Chesapeake Bay area it can begin when water temperatures reach 12 degrees C. Females can carry up to 50,000 eggs which take several days to hatch. Once the spawning is done, the male will chase the female out of the nest and guard the eggs. Several countries where this species has been introduced report that it causes ecological problems. , Hydrodynamically, the bluegill exhibits specific flow patterns that accompany its C-start escape response. The fish play a key role in the food chain, and are prey for bass, other (sunfish), northern pike, walleye, muskies, trout, herons, kingfishers, snapping turtles, and otters. Description: The bluegill has a significantly compressed, oval or roundish body, a small mouth, and a small head.
