Nothobranchius brieni

Unknown

Overview

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

Nothobranchius brieni faces severe pressure from habitat degradation as seasonal wetlands across its limited range are converted for agriculture and urban development. The species' dependence on ephemeral pools makes it particularly vulnerable to altered rainfall patterns and water management practices that disrupt natural flooding cycles. Overfishing and collection for the aquarium trade further stress remaining populations in accessible locations.

Threat summary

Habitat

This annual killifish inhabits temporary pools, seasonal wetlands, and ephemeral water bodies that form during rainy seasons in East African savannas. The species requires shallow, vegetated pools that dry completely during drought periods, triggering the unique lifecycle adaptations typical of annual killifish.
