Welcome back to Flora-Fauna Fridays! We’re glad to see that you're not hem-hawing or pawpaw-ing around after we talked about the PawPaw last week. This week, after realizing we’ve not talked about a single fish this year, we thought it was overdue to talk about the likeliest catch around: the Bluegill (Lepomis macrochirus)!
- Bluegill are one of the most commonly caught and seen fish in the state of Tennessee. Often measuring between 4 and 12 inches in length, the maximum has been 16 inches. Most adult bluegill will weigh about 12 oz, but the record Bluegill was 4 lbs, 12 oz. It was caught at Ketona Lake, Alabama in 1950!
- Bluegills are often easily identified by the dark blue coloration on the sides of their heads and chins, along with dark vertical bars on their sides that fade into the abdomen. They will also commonly have a yellowish breast and abdomen. They will also have between 9 and 11 dorsal (or back) spines with long, pointed pectoral (or side) fins.
- Diets for these fish when juvenile can often consist of small insects, and microscopic or near-microscopic organisms. Once adults, it will often transition to aquatic insect larvae (like mayflies or dragonflies) but can also include creatures like crayfish, worms, or other small fish! As for predators, Bluegill have plenty including: bass, walleye, catfish, and turtles. And those are just the other aquatic life!
- L. macrochirus often live in shallow waters of rivers, ponds, and lakes. They are most abundant near the cover of vegetation, submerged wood, or rocks where they can find prey to feast on or shelter from predators. They range to be in most waterways east of the Rocky Mountains, from Texas in the west to Florida and New York to the north and east. They’ve also been found in the Chesapeake Bay, which shows they can survive in brackish (or salt- and freshwater mixed) areas.
- Spawning of Bluegills often takes place from April to September, with the male picking the location and then creating the nest for the female to lay her eggs. Once the female lays her eggs, often measuring in the tens of thousands, the male will release his s***m over them. The male will protect the nest even after the young emerge. This fish will go on to live, on average, 5 to 6 years.
- While there is no way to know for certain, it is believed that the bluegill is the most caught fish in the United States and is often most fishermen's first catch!
- Unlike most of the flora and fauna we’ve discussed, the Bluegill is one that will take active effort to locate. They can be caught throughout both the Duck and Little Duck Rivers, with some anglers telling us that the plunge pool below Step Falls and the Forks of the River areas are some of the best places to catch them.
