Acadian Redfish

The Beluga Whale - A species in need of your help in Newfoundland and Labrador [PDF]

Name:

Acadian Redfish (Sebastes fasciatus)

Local Names:

beaked redfish

SARA status:

Not listed

Size:

Reach lengths of up to 70 cm

Diet:

A combination of small invertebrates (copepods, euphausiids, shrimp) and small fish (myctophids or lanternfish)

Where it is found:

In the deep waters of the Gulf of St. Lawrence and the Laurentian Channel and along the continental slope from the southwestern Grand Banks to Hamilton Inlet Bank. In deep channels and bays around Newfoundland and Labrador.

Threats:

Directed fishing is the main factor responsible for fluctuations in redfish abundance. By-catches from other fisheries, particularly the shrimp fishery, and unfavourable environmental conditions may also have a fairly significant impact on redfish populations.

Habitat:

Inhabit cold waters from 1OOm to 700m and are generally stratified by depth, with smaller redfish being found in shallow waters and larger redfish in deeper waters.

Notes:

There are three species of redfish in Newfoundland and Labrador waters; the Golden redfish (sebastes marirus), the Acadian Redfish (sebstes fasciatus) and the Deepwater redfish (sebastes mentella) with the latter two species known as the "beaked" redfish. All three species are very similar to each other and it is difficult to distinguish between them.
