生物学特性     字汇 (例如 epibenthic)

Adults inhabit freshwater rivers and lagoons, as well as brackish estuaries and coastal marine waters. Can tolerate temperatures from 11°C to 38°C. Large groups of juveniles are often encountered (Ref. 44894). Feed on arthropods, insects, aquatic plants, mollusks, prawns, crayfish, fishes and bottom detritus. Nest is constructed among gravel where eggs are deposited forming a mound (Ref. 205). The only species among oral incubating ariids exhibiting no parental care (Ref. 205). Breeding takes place from September to February (Ref. 44894). Marine populations of A. graeffei appear to undertake extensive anadromous migrations associated with breeding, but no such movements were observed in the fluviatile population studied (Ref. 38559).

栖息于淡水的河川与舄湖, 以及半咸淡水河口与海洋沿岸水域。 容忍从 11 °C 到 38个 ° C. 的温度 大群体的稚鱼时常被见到。 (参考文献 44894) 吃节肢动物,昆虫,水生植物,软件动物,虾,小龙虾,鱼与底部碎屑。 繁殖从十一月到二月发生。 (参考文献 44894) A. graeffei 的海洋族群似乎进行伴随着繁殖的广泛溯河洄游产卵的回游,但是没有如此的运动在被研究的生活在河中的族群被观察。 (参考文献 38559)
