215 km²

Approximate % coverage contribution to Marine Conservation Targets

<0.01%

Conservation Objective

Cold-water sponge protection

Ecological Components of Interest

Species of regional importance: cold-water sponges

• Why they are important: Cold-water sponges are fragile, slow to recover, structure-providing species.

Habitat that is important to biodiversity conservation: cold-water sponges

• Why they are important: This conservation area contains a high concentration of sponges (Porifera spp.). Some species in this group may create structures that provide diverse habitat for many other species.

Prohibitions

The ecological components of interest are effectively conserved through the following prohibitions:

All fishing that uses bottom-contact gear, such as bottom trawls, dredges, bottom seining, traps, gillnets, and bottom longlines.

Other Considerations

No human activities that are incompatible with the conservation of the ecological components of interest may occur or be foreseeable within the area.

Environmental Context

This conservation area includes part of a community of sponges classified as a significant benthic area (CSAS SAR - 2017/007) in the Estuary and Gulf of St. Lawrence bioregion. The area also includes other biologically significant features, such as a high concentration of Duva sp. and Gersemia rubiformis soft corals, the presence of the large structure-providing Hemigellius arcofer sponge, and at least four species of rays and wolffish.

High concentrations of these corals and sponges create habitat with complex structures that provide refuge, feeding, and rearing areas for many marine species, thus supporting greater biodiversity.

Prohibiting bottom-contact fishing gear makes it possible to directly protect the fragile structure of corals and sponges, and can also help protect the fish and invertebrate species that rely on this habitat.
