Additional field notes
The silver shiner’s distribution is uneven within the river systems that make up its range.

River habitat and local occurrence
FishBase records adults in rocky riffles and runs of rivers ranging from small to large. These are flowing sections of the river, so an outline of the drainage alone does not describe the habitat occupied by an individual fish.
Its range summary describes the species as commoner toward the east and rarer in western portions. It notes gaps in the lower Wabash, lower Cumberland, and much of the lower Tennessee systems, and rarity in the Lake Erie drainage. These qualifications are useful when reading a broad range map: being inside a named basin does not establish presence in every tributary or river reach.

Diet and feeding
The FishTraits compilation records these diet categories for this species: algae or phytoplankton; 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 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 medium to large rivers, streams and small rivers.
The source records associations with cobble, boulders, organic debris. 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 (NC). This is a regional calendar, not a range-wide schedule.
The reproductive-guild classification includes spawning on open substrates without guarding the brood.
Size and recorded longevity
FishTraits reports a maximum total length of 14 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.
