Farmed salmon, what impacts on the environment?

Chile and Norway are leaders in salmon farming, which was launched in the early 1960s, a gold mine for these countries. Nevertheless, it causes many damages to the environment.

 

According to Le Monde diplomatique, Chile raises just over 23% of salmon consumed worldwide. As for Norway, its production in 2017 accounted for almost 55% of world production.

These countries have risen to the top of the podium in the production of farmed salmon.

In Chile, non-governmental organizations and associations complain about the environmental impacts. The region of Magellan is the home of cetaceans, penguins … In the fjords, we have calculated that water takes thirty years to renew itself completely. Why install a polluting industry in such a fragile ecosystem ? says Estefania Gonzalez, coordinator Greenpeace Chile.

Fishermen in the region also find that catches are becoming increasingly rare. Those responsible for these fishermen are the salmon farmers with their farming.

It should also be noted that the sector consumes a lot of antibiotics to fight diseases. This abuse may be due to the trauma of the infectious salmon anemia that hit Chile in 2007.

The massive use of antibiotics will result in a weakening of the ecosystem and could make some bacteria more resistant, which would pose problems in the future. In addition, what about salmon doped with antibiotics that escaped from the farms ?

The Chilean government seems to be aware of all these misdeeds. He asserts that the allocation of new concessions in certain regions is not an option.

Hopefully this questioning is the beginning of an awareness that would allow to organize the production and consumption of salmon otherwise.
