About Missouri Saddled Darter
The Missouri saddled darter (Etheostoma tetrazonum) 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 Missouri, where it occurs in the Ozarks from the Gasconade River to the Osage and Moreau rivers. It occurs in fast gravel and rubble riffles of small to medium rivers. This species can reach a length of 9.0 cm (3.5 in).
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 medium to large rivers.
The source records associations with gravel, cobble. An association indicates reported use, rather than an exclusive requirement.
Reproduction and parental care
The compilation reports a representative maturity age of 2 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 (MO). This is a regional calendar, not a range-wide schedule.
The reproductive-guild classification includes hiding a brood without subsequent guarding.
Size and recorded longevity
FishTraits reports a maximum total length of 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 4 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.
