| Descrição do ciclo de vida e do comportamento reprodutor | The spawning run from the sea to freshwater streams begins when river temperature rises to about 4.4° but the fish stop running if temperature exceeds 7.8°C. Males predominate the early part of the run, but their numbers are equalled or exceeded by females later (Ref. 10276, 11699). Adults usually die after spawning but some move back to the sea and return to spawn a second time (Ref. 1998). Upon hatching, larvae are found near the bottom and are soon carried downstream to salt water and eventually found in the scattering layer of coastal waters (Ref. 27547). |
