Abstract
Coastal and marine fish species composition varies greatly throughout the region and this variation is reflected in the subsistence fisheries as well as the commercial fisheries in the Kivalliq and Hudson Strait. There has been a shift in the presence and abundance of some fish species and locally there are observations of new species not historically found in those areas. However, not much is known about the biodiversity, distribution and abundance of coastal and offshore fish and invertebrate species, nor about the life histories of the key anadromous species in the region. This chapter provides an overview of known fish assemblages in the Greater Hudson Bay Marine Region, the subsistence fisheries of Arctic char, and observed changes in fish assemblages and stressors on species related to climate change.
