Salmon is grown in ponds, lakes, rivers and oceans
Great Lakes steelhead were introduced into the region from Pacific Northwest fish species
fish.
Great blue herons are not native to Japan, so there is likely no ideogram for that species.
There are two species of Great Apes not native to Africa, Pongo abelii, the Sumatran Orangutan, and Pongo pygmaeus, the Bornean Orangutan, both of which are native to Asia (Sumatra and Borneo).
Introducing new species threatens biodiversity in several ways. The new species may upset the food chain in an area. If a species grows faster than native species, they may eat all of the food, leaving little for the natural fauna. The new species may also, conversely, be great food for an existing species which would give one species a great growth advantage over others.
Clownfish are found in warm waters of the Pacific and Indian Oceans, typically in coral reefs and lagoons. They form symbiotic relationships with certain species of sea anemones, where they find protection and shelter.
Many native mussel species in the Great Lakes region are likely to face significant challenges due to habitat loss, pollution, and invasive species. These factors can lead to declines in their populations and disrupt the ecosystem balance. Conservation efforts and habitat restoration are crucial to help sustain these species, but their survival will depend on effective management and mitigation of threats. Without intervention, some native mussel species may face extinction.
The round goby, an invasive species, can disrupt the balance within an ecosystem by outcompeting native fish species for resources, preying on native fish eggs and larvae, and altering the food web dynamics. This can lead to declines in native fish populations and changes in the overall community structure of the ecosystem.
Salmon typically live in freshwater environments, such as rivers and streams, during specific stages of their life cycle. They migrate to the ocean as adults and return to freshwater to spawn. However, there are also species of salmon that spend their entire life cycle in freshwater lakes.
