Major Habitat Type

Temperate coastal rivers

Drainages flowing into

Korea Bay, Yellow Sea



This ecoregion includes the Yalu basin (forming the border between China and North Korea), and the rivers of the Korean Peninsula that drain to the west coast. 

Description of endemic fishes

16 endemic to the ecoregion and 17 that are shared only with Southeastern Korea [ecoregion 639]

Justification for delineation

Delineations were determined using a bottom-up approach that employed both published and unpublished field data and expert assessment (Abell et al. 2008; Kim 1997). This ecoregion was distinguished by its fauna and zoogeography (M. Kottelat pers. comm. 2006).

Level of taxonomic exploration

There is very little data for North Korea, and the data is not well reconciled with adjacent areas in China. This suggests that the fish fauna of northeastern China should be re-examined in detail (M. Kottelat pers. comm. 2006).
