Overview

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

Sebastes paucispinis faces severe population decline primarily due to overfishing and bycatch in commercial fisheries targeting other rockfish species. The species' extremely slow growth rate and late sexual maturity make it particularly vulnerable to fishing pressure, as populations cannot recover quickly from exploitation. Historical overharvesting has reduced populations to critically low levels, with continued fishing mortality preventing recovery despite some management measures.

Threat summary

Habitat

This rockfish species inhabits deep rocky reefs and continental shelf waters along the Pacific coast, typically found at depths between 50-400 meters. It prefers areas with complex bottom structure including rocky outcrops, boulder fields, and submarine canyons that provide shelter and foraging opportunities.

Frequently asked questions

Why is Sebastes paucispinis classified as Critically Endangered?
Sebastes paucispinis is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Sebastes paucispinis faces severe population decline primarily due to overfishing and bycatch in commercial fisheries targeting other rockfish species. The species' extremely slow growth rate and late sexual maturity make it particularly vulnerable to fishing pressure, as populations cannot recover quickly from exploitation. Historical overharvesting has reduced populations to critically low levels, with continued fishing mortality preventing recovery despite some management measures.
Where does Sebastes paucispinis live?
Sebastes paucispinis occurs in Canada, Mexico, and United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sebastes paucispinis?
The main threats to Sebastes paucispinis are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
