Canadian Prime Minister, Justin Trudeau is taking care of the environment. Yes, due to environmental concerns, Canada is actually phasing out the farmed salmon. Farmed fish is actually bringing a negative impact on the environment. The government is actually boosting the health of the wild fish populations by phasing out the farmed salmon.
The new plan launched by the Canadian government will phase out the farmed salmon by 2025 in British Columbia. Here, we are actually referring to net-pen farming. Most people might not have a proper idea about net-pen farming. Well, it actually refers to raising a lot of fish in the ocean in a large net. Salmons in the supermarket come from this type of fish farming. Now, the government is discontinuing this type of agriculture because this is not good for the environment.
You can compare it with livestock operations for industrial purposes. Yes, they are raised in the open ocean in a large net. Now, the excretion of those fishes infects the nearby environment. It creates problems for other fishes. So, the government is bringing a new act to prevent this. This is the first act on aquaculture, and it will assure environmental sustainability in the sphere of the fishing industry.
Salmon Farming Is Hurting The Environment
Farmed salmon is basically jammed in a net. Disinfectants, antibiotics, and many more chemicals are injected. Talking about a typical fishing farm in British Columbia, well, it has almost 20 to 30 net pans. A report presented by Fraser Riverkeeper shows this. Each net pen consists of hundreds of salmon. They are packed very tightly together. These fishes generate a lot of waste and this waste is actually hampering the ecosystem. Talking about waste, it consists of mercury, copper, nitrogen, and zinc. These contaminants can lead to harmful outcomes. If we talk about copper, it can harm the crustacean communities that live near the net-pens. Zinc can lead to negative outcomes on marine worms and algae. A recent study has shown that the level of mercury in the rockfish that are living near net-pens has been elevated.
Well, another research has shown that farmed salmon often escape from the nets and they swim in the open ocean. They basically compete with other wild fish and thus, they spread diseases.
Now, if we talk about the future scenario, the fisheries can go with a closed-containment system instead of net-pen farming. It will be a safer option considering the present situation, and it will be healthier for consumers as well. Giving attention to personal health and the environment go hand-in-hand.
As of now, you have probably understood why Canada is phasing out salmon farming.
