Overview

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

The Northern Nutclam faces significant pressure from commercial bottom trawling and dredging activities that physically disturb its benthic habitat and reduce population densities. Climate change-induced ocean acidification poses an additional threat by weakening the species' calcium carbonate shell structure, while warming waters may alter the distribution of suitable habitat along the continental shelf.

Threat summary

Habitat

The Northern Nutclam inhabits soft sediment substrates on the continental shelf and upper slope, typically at depths between 50-400 meters in cold temperate waters. This bivalve species burrows into muddy and sandy bottoms where it filter-feeds on organic particles and plankton.
