| Descripción del ciclo vital y del comportamiento de acoplamiento | The spawning run involves an upward migration beginnning as early as late June. The spawning act occurs at night or during the day. A female begins to swim vertically toward the surface, belly upstream. A male (sometimes 2 or 3) joins her and eggs and milt are released as fish approach the surface. The fish break the surface, fall away from each other and return to the bottom. After spawning most move downstream. The young of the year move downstream during their first year and do not return until they are sexually mature. Generally, the same spawning grounds are utilized yearly (Ref. 27547). |
