概述

Labeo angra 是南亚至缅甸分布的底栖鲤科鱼,背部偏褐,体侧与腹部偏黄,一条黑至蓝黑色侧纹从眼部延伸至尾鳍基部。它会在原生河流水系中进行每年的繁殖迁徙。

分布与栖息地

已知记录涉及巴基斯坦、尼泊尔、印度北部、孟加拉国与缅甸。尼泊尔记录包括戈西河和格尔纳利河,模式地点位于印度布拉马普特拉河。

主要在底层活动,但底栖与季节迁徙并不矛盾,不能把它理解成始终不离开一处底部藏身点的鱼。

繁殖

自然生活中每年会为繁殖而在河流水系内迁移。迁徙习性本身没有给出水族箱内的繁殖办法,不能直接套用其他鲤科鱼的产卵布置。

补充说明

辨认时可关注褐色背部、黄色体侧腹部及从眼到尾基的深色纵带这一组合。野鲮属种类很多,外形近似和属级分类讨论不能替代本种具体身份核对。

Overview

Labeo angra is a bottom-associated cyprinid distributed from South Asia into Myanmar. A brownish back, yellowish sides and belly, and a dark blue-black stripe from the eye to the tail base form its characteristic color pattern. It undertakes annual reproductive movements within its native rivers.

Distribution & habitat

Records cover Pakistan, Nepal, northern India, Bangladesh, and Myanmar. Nepalese localities include the Kosi and Karnali systems, while the type locality is the Brahmaputra in India.

It is predominantly benthic. Bottom association and seasonal migration are compatible habits, so it should not be regarded as a fish permanently confined to one small bottom retreat.

Breeding

Wild fish migrate within river systems to reproduce annually. Migration alone does not establish an aquarium breeding method or justify transferring a spawning arrangement from another cyprinid.

Notes

Use the combination of dorsal brown, yellowish flanks and abdomen, and the eye-to-tail stripe when checking identity. The large and complex genus contains many superficially similar fishes, and broad generic discussions do not replace species-level identification.
