| Descrição do ciclo de vida e do comportamento reprodutor | Spawners move inshore or upstream to the marsh areas to spawn (Ref. 27547). Generally, spawning occurs during the day. The sexes pair and a larger female is usually attended by one or two smaller males. They swim through and over the vegetation in water usually less than 17.8 cm, releasing eggs and sperm simultaneously at irregular intervals (Ref. 1998). Eggs are deposited in flooded areas and on submerged vegetation over a period of 2-5 days (Ref. 59043). Only 5 to 60 eggs ae released at a time (Ref. 27547). This act is repeated every few minutes for up to several hours, after which the fish rest for some time before resuming. During the resting period, both male and female may take new mates, or they may continue together for several days until all eggs are extruded. Spawned-out adults may stay on the spawning grounds for as long as 14 weeks, but most leave within 6 (Ref. 27547). |
