概述

长吻(Hemibarbus longirostris)是远东地区的河流鲤科鱼,吻部延长,成鱼常在靠近底部的位置集群。观察其活动时,应把底床附近的缓流空间与整个河道的流水环境一起考虑。

分布与栖息地

原生于中国东北、俄罗斯东南部、朝鲜半岛及日本,模式产地在韩国。偏好清澈、富氧的河流,底质可为沙、砾石、岩石或泥。虽然生活在流水中,成鱼往往选择流速较缓的河段,在底床上方群游。

食性与喂食

野外摄食底栖甲壳动物、昆虫、软体动物和其他较大型无脊椎动物,取食对象以动物性食物为主。

Overview

An extended snout characterizes Hemibarbus longirostris, an eastern Asian river cyprinid. Adults commonly gather close to the bottom. Their use of quiet near-bed areas is an important qualification to the broader description of a running-water fish.

Distribution & habitat

The native distribution includes northeastern China, southeastern Russia, the Korean Peninsula, and Japan. The type locality is in South Korea. Clear, well-oxygenated rivers with sand, gravel, rocks, or mud provide habitat. Within these rivers, adults tend to group immediately above the bed in slower reaches.

Diet & feeding

Wild feeding records include benthic crustaceans, insects, mollusks, and other large invertebrates. These records describe an animal-based bottom-feeding diet.
