Rough Shiner

Diet and feeding

The FishTraits compilation records these diet categories for this species: algae or phytoplankton; aquatic or other vascular plants; detritus or unidentified plant material; invertebrates or larval fish; fish or frog eggs. These are broad categories, not a claim that every individual consumes every example in a category.

Reported feeding positions include bottom feeding and surface or water-column 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, creeks.

The source records associations with muck, clay or silt, sand, gravel, cobble, vegetation. An association indicates reported use, rather than an exclusive requirement.

Reproduction and parental care

The compilation reports a representative maturity age of 1 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.

Batch or serial spawning has been reported somewhere in the species’ range. This does not establish the same spawning pattern for every population.

Recorded spawning months are Apr, May, Jun, Jul, Aug for the source’s reporting region (MS). 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 2 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.

Native range

Mobile Bay and Pascagoula River drainages, mostly below the Fall Line, Alabama and Mississippi; Bear Creek system (Tennessee River drainage), Alabama and Mississippi (Page and Burr 1991).

Introduction history

Unknown; probable bait bucket release. The source of introduced fish found in for the Chattahoochee River was possibly the Tennessee or Coosa drainage in Georgia.
