概述

胸斑长背魮(Labiobarbus siamensis)具有很长的背鳍和延伸到眼后较远处的口须。鳞片斑点形成纵纹,肩斑可有可无,因此名字中的斑点不能单独作为鉴定条件。

分布与栖息地

见于老挝、泰国、柬埔寨的湄公河水系,以及泰国中部昭披耶河和邦巴功河。可利用各种规模的河溪,雨季通常会进入淹水的平原与森林。

食性与喂食

野外取食微小颗粒,包括浮游植物、浮游动物、附着生物及底栖藻类。食物来源既有植物也有动物,并不限于某一种藻。

补充说明

背鳍中部有淡暗条带但无红色,尾鳍可稍带红而缺少明确条纹。辨识应综合这些鳍纹与口须长度;旧文献可能以 Dangila 属名收录。

Overview

The long dorsal fin and extended barbels of Labiobarbus siamensis are useful recognition features. Aligned scale marks form body stripes, while the shoulder spot varies and may be absent.

Distribution & habitat

The range includes the Mekong, Chao Phraya and Bang Pakong systems. It occupies channels of different sizes and moves onto inundated plains and into flooded forest when water rises.

Diet & feeding

Natural feeding includes planktonic animals and plants as well as attached growth and bottom algae. This is a mixed small-item diet rather than exclusive consumption of one algal type.

Notes

A dusky central dorsal band, absence of dorsal red and a tail lacking sharply defined stripes help identification. Historical references may place the fish under Dangila.
