Inflammatory bowel disease (IBD): Inflammatory bowel diseases (IBDs) like ulcerative colitis and Crohn's disease, are often controlled by a combination of medications that are used in a step-wise approach.
Habitats. Salmon live in different habitats: freshwater and ocean habitats. Freshwater habitats: When in freshwater, salmon fry and parr like to live in areas of gravel, cobbles and boulders and where the water is clean and unpolluted. Smolts migrate from our rivers to the sea.After a year or more at sea, adult salmon return from their feeding grounds back to their river.cean habitats: We know where salmon go to feed in the sea-grilse swim to near the Faroe Islands, and multi sea winter salmon swim to sub arctic seas near Greenland. But, we are not sure exactly which habitats salmon prefer and what happens to them whilst they are at sea.
Salmon are native to tributaries of the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus). Many species of salmon have been introduced into non-native environments such as the Great Lakes of North America and Patagonia in South America.Salmon are intensively produced in aquaculture in many parts of the world.osalmo driftwoodensis, the oldest known salmon in the fossil record, helps scientists figure how the different species of salmon diverged from a common ancestor. The British Columbia salmon fossil provides evidence that the divergence between Pacific and Atlantic salmon had not yet occurred 40 million years ago.
