GILBERT: FISHES OF THE SUBGENUS LUXILUS


 Spawning takes place usually in shallow to moderately deep riffles
(3 to 8 inches) with a gravel or rubble bottom. The fish may excavate
small depressions in gravel or sand in running water, or utilize the
nests built by other species, even when these are in pools. It appears
to prefer the nests of other species when available, with those of such
nest-building forms as Exoglossum maxillingua, Semotilus atromacu-
latus, Semotilus corporalis, Campostoma anomalum, and species of
Hybopsis (subgenus Nocomis) most frequently utilized.
 Males arrive first on the riffles, sometimes in large numbers (Fow-
ler, 1909; 540; Raney 1940a: 5). There each individual attempts to
hold a small territory. Females meanwhile remain a short distance
downstream, usually in the first pool. When ready to breed the
females move upstream, take a position over a male, and shortly
thereafter the spawning act is consummated.
