| Descrição do ciclo de vida e do comportamento reprodutor | "Individual females spawn with several males. Males assemble at spawning grounds and follow ripe females, often with much splashing, to shallow riffles. Males may exhibit courting or sneaking tactics in spawning site. Courting males follow females to spawning site and, during the spawning act, one male swims head to head with the female. Sneaking males, waiting in the spawning site, then join the couple and try to fertilize eggs. Up to 130 males have been reported to be involved in a single spawning act. Females deposit non-sticky eggs in 2-3 portions into excavations made in the gravel" (Ref. 59043). |
