About Lollipop Darter

The lollipop darter (Etheostoma neopterum) is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States. Lollipop darters are approximately 1.4 to 2.4 inches (3.6 to 6.1 cm) long.

Distribution

The range of the lollipop darter is restricted to the Shoal Creek system in northwest Alabama and south-central Tennessee.

Ecology

The lollipop darter eats larvae, insects, and small crayfish. Their predators are any fish larger than they are. Crayfish are predators to the fry and potentially to the adults based on the size of the crayfish.

Lifecycle

Female lollipop darters mature at one year of age, whereas the males take two years to mature. Spawning occurs from March to May. If temperatures are not in their preferred range, they will delay reproduction for that breeding season.

The male gets a specific color on a dorsal fin during breeding time. The lollipop darter is in the group known as egg-mimic darters. Males make a cavity under stones and other objects. The eggs are laid in a cluster under objects in the cavities where the males protect them. They fertilize the eggs externally. The female will spawn multiple times with the male before leaving. Males can mate with more than one female over the course of the breeding season. When males breed with more than one female, they will guard all the nests they have.

Management

The lollipop darter is being considered for the endangered species list in the state of Tennessee. In Alabama, it is illegal to capture and transport this species of darter. It is a potential endangered species and is up for debate to be added to the list. It is a threatened species due to its low population and small range. Their habitat encompasses only 135 square miles (350 km).

Diet and feeding

The FishTraits compilation records these diet categories for this species: invertebrates or larval fish. These are broad categories, not a claim that every individual consumes every example in a category.

Reported feeding positions include bottom feeding. The compilation combines published observations; diets can vary with age, locality, and available food.

Habitat preferences

Reported habitat associations include streams and small rivers.

The source records associations with gravel, cobble, bedrock, vegetation. An association indicates reported use, rather than an exclusive requirement.

Reproduction and parental care

The compilation reports a representative maturity age of 1.5 years. Its maturity field summarizes mean, median, or modal estimates, usually for females; male estimates can be used when female data are unavailable. It is not a fixed age at which every fish first breeds.

Recorded spawning months are Apr, May for the source’s reporting region (TN). This is a regional calendar, not a range-wide schedule.

The reproductive-guild classification includes guarding eggs or young at a spawning substrate or nest.

Size and recorded longevity

FishTraits reports a maximum total length of 8.9 centimetres. Some entries use an estimated asymptotic length; this value should not be treated as a certified record catch.

Recorded longevity in the compilation is 3 years. Wild observations were preferred, but captive records were accepted where wild records were unavailable, and unspecified records were assumed wild. The value is not a guaranteed wild lifespan or an aquarium life expectancy.
