Cheimerius matsubarai

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Cheimerius matsubarai faces significant pressure from intensive commercial and recreational fishing throughout its range in the Northwest Pacific. The species is particularly vulnerable due to its slow growth rate and late sexual maturity, making populations unable to recover quickly from fishing pressure. Coastal development and habitat degradation in shallow reef areas where juveniles develop further compound population decline risks.

Threat summary

Habitat

This marine fish inhabits rocky reefs and coastal waters in the Northwest Pacific, typically found at depths ranging from shallow nearshore areas to approximately 200 meters. Juveniles often utilize shallower reef areas and seagrass beds as nursery habitat before moving to deeper adult territories.
