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 features a high concentration of sponges (Porifera spp.). Some species in this group create structures that provide diverse habitat for many other species.
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.
No human activities that are incompatible with the conservation of the ecological components of interest may occur or be foreseeable within the area.
This conservation area includes 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 important features, such as a high concentration of Duva florida and Gersemia rubiformis soft corals, the presence of the large structure-providing Hemigellius arcofer sponge, and at least three species of rays and wolffish.
High concentrations of 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.
Following the signing of the Canada–Quebec Collaborative Agreement to Establish a Network of Marine Protected Areas in Quebec in March 2018 (available in French), the governments of Canada and Quebec are evaluating the possibility of reinforcing coral and sponge conservation measures in the Gulf of St. Lawrence by prohibiting certain activities other than fishing in certain zones.
