Range and Identity
Notropis semperasper is the identity retained for Roughhead Shiner. The upper James drainage provides the secure geographic framework. A state designation in a short summary should not override a verified watershed location, so collection records should retain the actual tributary.
Habitat and Behavior
Adults inhabit clear rocky pools and backwaters in rivers of different sizes. These sheltered channel features contrast with a uniformly fast-riffle description. The immediate current, bottom and connection to the main river add useful detail to an occurrence record.
Food and Life History
The upper reference is nine centimeters total length, with 5.5 centimeters given as a common size. The checked account does not establish detailed migration behavior, diet or independent maximum mass. Those gaps are not filled from the ecology of another upper-basin shiner.
Field Note
Record the named tributary along with the river system. That detail helps prevent geographic errors when a narrowly distributed fish is summarized in a very short reference entry.
