There are nine different spieces of salmon in the world spanning three different continents.
Salmon can be found in Asia, North America, and Europe (but there are some non native runs in Patigonia). Salmon face many dangerous through out their lives. When salmon are young their biggest predators are kingfishers, Blue heron, american eals, otters, ducks and osprey. When they finally make it out to the ocean the list only gets bigger. In the ocean their predators become humans, seals, sharks, cod and any bird big enough to hold a salmon. And finally, the list only gets longer when they return to the river. When they return add bears and wolfs and any other carnivore present.
But the biggest threats to salmon remain over fishing, habitat loss and pollution.
Oliver, this is a very interesting article. But the information only makes the it more difficult to eat more healthily by eating more fish and less beef!
ReplyDeleteI guess we humans are also one of the salmon world's bigger predators. Think about all the fishing that is done in order to supply the world's markets and restaurants with salmon!
Also, I just started taking 100% wild salmon fish oil tablets for the omega oil that is supposed to be very good for you! I am feeling a bit guilty now!
