Corsair and Georges Canyons Conservation Area (Restricted Bottom Fisheries Zone)

Ecological Components of Interest

Species of regional importance: Cold-water corals

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

Habitat that is important to biodiversity conservation: Cold water corals

• Why it is important: This area includes large, tree-like “bubblegum corals” (Paragorgia arborea) and “seacorn corals” (Primnoa resedaeformis).These structure-forming species provide habitat for many other species.

Prohibitions

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

All commercial bottom-contact fishing gear.

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

Corals play an important functional role for numerous forms of marine life. They act as spawning and breeding grounds, nurseries, and refuges for many aquatic species.

The dense aggregations created by large, structure-forming cold-water corals can alter bottom currents and provide niche space for other organisms.

Prohibiting bottom-contact gear can protect not only the corals but a diversity of other species of fish and invertebrates that utilize the complex structural habitat the corals provide. This area can act as a natural refuge area that may contribute to increased species productivity, which in turn, could potentially lead to increased abundance within and adjacent to the area.
