Oceania: Australia (including Tasmania), Lord Howe Island, New Zealand and the Chatham Islands. South America: Ranges from along the Chilean side of the Andes near Valparaiso to the southern extremity of the island chain southeast of Tierra del Fuego. Also on the eastern side of the Andes in Argentina in isolated lakes (Meliquina, Traful, Nahuel Huapi, Gutierrez, and Pellegrini) which drain into the Atlantic Ocean via the Negro River. It occurs on Falkland Islands.

Facultative air-breathing (Ref. 126274); Occur in a wide variety of habitat, but mostly in still or slow-flowing waters, mainly in streams, rivers and lakes within a short distance of the sea. Can survive in salinities up to 50 ppt. Feed on aquatic and terrestrial insects, and crustaceans. Adults typically migrate downstream into estuaries during high spring tides in autumn to spawn on fringing vegetation. Spawning does not occur beyond the river estuaries, making this species 'only marginally catadromous' (Ref. 46888). Many perish after spawning but some survive another year. Eggs develop out of water for two weeks and hatch upon the arrival of the next spring tide. Newly hatched larvae spend their first 5-6 months at sea before returning to fresh shoals of whitebait during spring. An important component of whitebait fisheries throughout the Southern Hemisphere (Ref. 44894). Utilized fresh and eaten fried (Ref. 9988, 44894).
出现于各式各样的栖息地, 但是大部份在静止或流动很慢水域中, 主要在溪流，海洋的短距离里面的河川与湖泊。 此鱼种有时进入半咸淡的溪流而且能存活在盐度高达 50个 ppt。 吃水生与陆栖的昆虫 , 与甲壳动物。 生鲜使用与油炸后食用.(参考文献 9988,44894) 成鱼典型地进入河口之内在高春天潮的时候秋天时移动向下游在岸边的植丛上产卵。 多数在产卵之后死亡，但是一些在另年存活。 卵发育达二个星期离开水面而且在下一个春天潮的抵达之上孵化。 最近孵化了仔鱼在海上度过他们的第一个 5-6 数个月在回到生鮮地之前白魚科的魚的魚群春天時。 在南半球各處的一個白魚科的魚漁場的重要組成.(參考文獻 44894)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
For diadromous populations: deposit eggs on dense terrestrial vegetation that is flooded by the high tide. The eggs develop out of water in humid condition during the next 2 weeks. Hatching takes place when a second series of high tides again wash over the eggs. For landlocked population: fish migrate up to the tributary streams during floods. Deposit eggs on the flooded grassy banks and complete their development after the water level subsides. Hatching occurs during subsequent floods.大洋洲: 澳洲 (包括塔斯梅尼亞) ，羅得豪島, 紐西蘭與 Chatham 島。 南美洲: 分佈自沿著在維爾帕瑞索到附近的安迪斯山脈的智利的側邊火地島的島鏈東南的南方末端。 也在阿根廷在經由尼格羅河流入大西洋的孤立的湖 (Meliquina ， Traful ， Nahuel Huapi ， Gutierrez 與 Pellegrini) 的安迪斯山脈的東邊上。 它生存於福克蘭群島。
