Son aire de répartition s'étend depuis le Japon vers le nord et l'est à travers le détroit de Béring jusqu'en Alaska, puis vers le sud jusqu'en Californie. Il vit dans les zones rocheuses, le long de la pente continentale, à proximité des champs de blocs et sur les fonds de silt ou de galets, à des profondeurs se situant entre 25 et 900 mètres.

Shortraker rockfish are deepwater marine fish found in the North Pacific Ocean. Their range covers both sides of the Pacific, beginning in Japan and extending north and east across the Bering Strait to Alaska, then south to California. They live in rocky areas along the continental slope, near boulder fields and on silted or cobbled bottoms, at depths between 25 and 900 metres.

Dans l'Atlantique Ouest, le sébaste s'observe depuis l'île de Baffin jusqu'au New Jersey. Il vit dans les zones rocheuses, à des profondeurs allant jusqu'à 700 mètres (S. mentella se rencontre habituellement dans des eaux moins profondes que S. marinus).

Redfish, members of the scorpion fish family, are found in the north Atlantic Ocean. Redfish comprise two major species, Sebastes marinus and Sebastes mentella, the latter of which is further subdivided into two species (S. mentella and S. fasciatus). Generally speaking, all of these fish are treated as one and the same by everyone outside of the scientific community-they are virtually impossible to tell apart. In the western Atlantic, redfish range from Baffin Island to New Jersey, living in rocky areas at depths of up to 700 metres (S. mentella is usually found in shallower water than S. marinus, however).

Il se rencontre depuis le sud-est de l'Alaska jusque dans le sud de la Californie. Il vit typiquement à proximité des zones rocheuses du plancher océanique - en particulier là où se trouvent des structures verticales, comme des récifs et des crêtes.

Quillback rockfish are an inshore rockfish native to the Pacific Ocean. They occur from southeastern Alaska to southern California. As their name implies, they typically live near rocky areas in the ocean-particularly those with vertical relief, like reefs or ridges-typically at depths of 50-100 metres, although they have been found as deep as 275 metres.

Les berges en surplomb, les fosses profondes, les zones de turbulence, les zones rocheuses, les débris présents dans le cours d'eau et la végétation riveraine surplombant le cours d'eau offrent un abri approprié.

Migration areas consist of stream reaches that provide corridors for fish movement from one area of the watershed to another or, for anadromous (sea-run) salmonids, access to and from the sea. Migration areas must permit fish movement to critical habitats. The lack of barriers to migration in the main steam and tributaries, as well as adequate water flow are essential.

Son aire de répartition s'étend depuis l'Alaska jusque dans le sud de la Californie. Il vit sur les fonds rocheux ou graveleux, ou encore dans les peuplements d'algues brunes des baies, des estuaires et des zones rocheuses de l'océan.

Red rock crabs are native to the Pacific Ocean. They range from Alaska to southern California. They live in rock, gravel or kelp beds in bays, estuaries and rocky areas of the ocean from the low intertidal to at least 90 metres depth - although they have been caught in traps as deep as 230 metres. Red rock crabs often shelter in rocks or bury themselves in the sand to avoid predators such as river otters, sea otters, large fish and other crabs.

Son aire de répartition s'étend depuis l'Alaska jusqu'au sud de la Californie. Elle se rencontre dans les zones rocheuses accidentées près du plateau continental, à des profondeurs allant d'environ 50 à 400 m.

Widow rockfish are a marine species of fish found off the west coast of North America. They range from Alaska to southern California, living in rocky, high relief areas close to the continental shelf. Widow rockfish occur at depths ranging from about 50 to 400 metres. Like other rockfish on the Pacific coast, widow rockfish have a high commercial value. They are fished extensively in Canada, particularly off the northern coast of Vancouver Island and in Queen Charlotte Sound.

Dans l'Atlantique Ouest, elle est présente de Terre-Neuve-et-Labrador (et la baie d'Hudson) jusqu'au New Jersey alors que dans l'Atlantique Est, son aire de répartition s'étend depuis les eaux du Spitsberg, au nord, jusqu'au Portugal, au sud. La lompe se rencontre aussi au large de l'Islande et du Groenland. Elle privilégie les eaux froides et vit près du fond, habituellement dans des zones rocheuses où la végétation est abondante.

Lumpfish are marine fish found on both sides of the Atlantic. In the western Atlantic, they are found from Newfoundland and Labrador (and in Hudson Bay) to New Jersey. In the eastern Atlantic, their range extends from Spitsbergen in the north to Portugal in the south. Lumpfish also occur off Iceland and Greenland. They prefer colder water and live near the ocean bottom, usually on hard, rocky areas with plenty of vegetation.

Comme l'achigan à grande bouche ne fréquente jamais les zones rocheuses qu'affectionne l'achigan à petite bouche, les habitats de ces deux espèces se recoupent rarement, bien qu'elles peuplent souvent les mêmes lacs.

The habitat of largemouth bass is the upper levels of the warm water of small, shallow lakes and shallow bays of larger lakes. It is almost always found close to soft bottoms, stumps, and extensive growths of a variety of emergent and sub-emergent vegetation, especially waterlilies, cattails, and other pondweeds. Because it is rarely found in rocky situations characteristic of the smallmouth bass, the habitats of the largemouth and smallmouth basses seldom overlap even though the two species often occur in the same lake.

Les adultes migrent vers les eaux vives des zones rocheuses des cours d'eau qui sont dominées par des chutes ou des barrages infranchissables ou vers les hauts-fonds de roche ou de gros gravier des lacs.

The walleye is a cool-water species that prefers turbid waters in either large, shallow lakes or rivers, provided they are deep orturbid enough to give shelter in daylight. As their eyes are very sensitive to bright light, walleye often use sunken trees, boulders, weed beds, or thick layers of ice and snow as a shield from the sun. In more turbid water, walleye are more active during the day. Walleye spawn in the spring or early summer, depending on latitude and water temperature. Adults migrate to the rocky areas in white water below impassable falls and dams in rivers, or boulder to coarse-gravel shoals of lakes. Spawning takes place at night and the eggs fall into crevices in the rocky substrate. The eggs hatch in 12 - 18 days and by 10 - 15 days after hatching, the young disperse into the upper levels of open water.

On retrouve cette espèce au large dans les eaux froides et profondes, habituellement à des températures inférieures à 5oC et à des profondeurs variant entre 50 et 800 m, mais aussi dans des eaux aussi peu profondes que 25 m (populations de l'Arctique canadien). Elle préfère un fond de gros sable et de sable/coquillage avec zones rocheuses situées tout près où s'abriter et construire son nid.

This species is found offshore in cold, deep water, usually below 5oC and between 50 and 800 m in depth but as shallow as 25 m (Canadian arctic populations). They prefer a coarse sand and sand/shell hash bottom with rocky areas nearby for shelter and nest building. Spawning occurs in summer to late fall/early winter. As many as 54,600 large eggs (up to 6 mm in diameter) are laid in deep water in clusters on the sea floor and are guarded primarily by males. Growth rate is slower for this species than for the Atlantic and Northern Wolffish (Barents Sea). Fish become mature at seven years of age or older and can live to 21 years. The species does not form large schools and migrations are local and limited.

Les habitats aquatiques plus productifs tels que les zones rocheuses, vaseuses ou à végétation dense sont étouffés par le sable, ce qui réduit leur capacité à assurer la survie des poissons ou d'autres espèces.

Experience has shown that in areas where a natural beach does not exist in the first place, beach-building efforts are usually unsuccessful. This is particularly true in areas with strong currents and waves. Over time, artificial beaches created in areas with strong currents or waves are eroded away and the sand is deposited elsewhere. Beach sand may be move and be deposited on neighbouring properties, downstream, in deeper water or as a sand-bar that may interfere with navigation. More productive aquatic habitats such as rocky, weedy or silty areas are smothered by sand, reducing their capacity to support fish and other species. Deposited sand can show up a great distance from the original beach site. Sand usually does not migrate from beaches created in silty areas but will require ongoing maintenance to remain free of aquatic plants.
