Food chain

The deep sea layer fish : Typically marine species are found in this habitat. The most part of these species are also found in the Saint Lawrence estuary, but some of them are arctic species, relics of ancestral populations which thrived in the Saguenay fjord thanks to the favorable physical and geographical factors, and also to the rather exceptional conditions present in the fjord. Despite an extraordinary biodiversity, most of the Saguenay's ichtyological fauna is of boreal affiliation. This deep, cold, well oxygenated and highly salted water layer, is a haven for over 35 species of fish. We have selected for you a few of the inhabitants of this dark and cold kingdom where the temperatures oscillate around 1Celsius all year-round.

the Atlantic redfish

The cod, the Atlantic redfish and the Greenland halibut are favorites among the ice-fishing adepts. The cod, this great inhabitant of the deep, is also appreciated by epicurians. The Atlantic redfish, surprisingly orange colored fish with huge protubing eyes, is flat with both eyes on one side of its body and swims flat at the bottom on its opposite side. Fishermen also call it the turbot.

When ice-fishing, one never knows what he will catch, its a constant surprise. This activity is gaining in popularity, so the biologists have come up with a way to follow up on the catches in order to verify if the stocks aren't being overexploited. In this sense, alongside with fishermen, the biologists are working to maintain a healthy fish population for future generations.

The Laimargue, also known as the Greenland shark, is a threatening inhabitant of the deep. Constantly lurking for prey, this predator mainly feeds on other fish(cod, Atlantic redfish capelin, halibut,rays) but also feeds on sea mammals and aquatic birds, in fact most anything it can sink its teeth into. It is said that it is one of the biggest fish in the Atlantic, its length going up to 7,3 meters and weighing in at over 500 kg.

Greenland shark

Small luminescent organisms live as parasites around each of its eyes, they serve as lures for eventual prey. This magnificient shark stays far from the surface at over 1200 meters deep and its flesh is toxic.

The Aqualog society ( led a scientific expedition to study the Greenland shark in the Saguenay. Theirs objectives : To record video and still images of Greenland Sharks in the Saguenay fjord. To collect blood for DNA and toxicology testing. To promote the conservation of the Greenland sharks in the Saguenay fjord.

The seasnail : In finishing this brief foray in the universe of the Saguenay's fish, we would like you to meet other unusual inhabitants of this marvellous ecosystem. The fjord is filled with riches and surprises, like this seasnail with its long fin, weird little character of the deep, he only measures around 25 cm. Its pelvic fins are modified in order to form an adhesive disc, which makes it possible for this small fish to perch itself, like birds, on deep sea rocks.


The atlantic sea raven : Meanwhile, the atlantic sea raven is a medium sized fish but it looks a little on the gross side and is quite ugly with its bristled fins. Because of this it is very difficult to hold one without causing painful injuries. This grubby feeds on crab, shrimp, sea-urchins and marine worms. It also eats any deep sea inverterbrate and any fish it can find . This marine animal is another aspect of the multiple unusual personnalities inhabiting the majestic Saguenay fjord.
