Native Americans have always depended on salmon
for food. So did the first European settlers. Today salmon are caught
with a variety of nets, and also by anglers who go fly-fishing. The
anglers use brightly colored artificial flies, with names like "Bombers",
or "Royal Wulff" to tease the salmon into being caught. Many
anglers let their catch go unharmed. This is called Catch and Release
fishing.
Humans have hurt salmon in other ways. Dams have
blocked their migration upriver, and poor forestry and agricultural
practices large amounts of silt into the water, which can suffocate
eggs. Acid rain has also caused big salmon kills, especially in Nova
Scotia.
In some cases, we can try to fix these problems.
Fish ladders, which are a series of pools connected by small waterfalls,
can give salmon a way around dams. Fish hatcheries have also been used
to artificially raise salmon and release them back to the wild. However,
the best salmon hatchery remains a healthy river system.
Salmon are a healthy food for people to eat. These
fish have large amounts of stuff called omega 3 and omega 6 fatty acids,
which are good for your heart. There are not enough wild fish in the
ocean to provide salmon to markets. Now, fish farmers are rearing salmon
in sea cages, to try and meet this demand.
