Asia: endemic to Lake Taal (formerly Lake Bombon), Luzon, Philippines. This freshwater lake, linked to the sea via the Pansipit River, was part of Balayan Bay, South China Sea, and was formed by a series of volcanic eruptions in the 18th century (Ref. 5522).
亞洲: 塔爾湖 (從前湖 Bombon) ，菲律賓呂宋島的特有種。 這個淡水的湖, 經由 Pansipit 河連接了到海洋, 是 Balayan 海灣，南中國海的部份, 而且在 18 世紀內被由一系列的火山爆發形成。 (參考文獻 5522)

Inhabits lakes. This is the only species of Sardinella that is apparently found only, or even mainly, in freshwater. Presumably schooling. Also caught using ring nets (Ref. 5520). Mainly caught by gill net, beach seine, ring net and motorized push net (Refs.81494, 80728, 5520). Eaten fresh or dried (Ref. 5517). Is threatened by overfishing (Ref. 6308).
栖息于湖。 这是显然地，那是只发现于淡水或主要在淡水里的 沙丁鱼 的唯一的种。 推测为群游。 也使用环状网捕捉。 (参考文献 5520) 被吃生鲜地或干燥的.(参考文献 5517) 受到威胁的由于捕捞过度.(参考文献 6308)
