Salmon Farming

by Izi, Jack and Maggie

Salmon in America

Salmon was about 5% of all the fish we ate in 1989, but by 2004, that amount almost tripled to 13%. This made salmon ranks third among all the fish we eat in the United States after shrimp (25% of total fish eaten in the United States) and canned tuna (20% of total fish eaten in the United States) (all estimates from Knapp 2007). This means that from the year 2000 to 2004, Americans consumed an average of about 284,000 metric tons of salmon annually! this was approximately:

• one-third was Pacific salmon and two-thirds was Atlantic salmon

• one-third was wild and two-thirds was farmed

• one-third was domestic production and two thirds was imported

• three-fifths was fresh salmon, one-fifth was frozen salmon and one-fifth was canned salmon

How Salmon Farming Works to Catch and Grow Salmon


Salmonids are carnivorous and are currently being fed compound fish feeds containing fish meal and other feed ingredients, ranging from wheat byproducts to soybean meal and feather meal.

How does Salmon Farming Harms or benefit the ecosystem?

Salmon farming does harm the aquaculture production systems. Salmon farming uses net-cages in the ocean. Farm waste, chemicals and diseases are released into the water, which harms other marine life. Deaths of natural predators occur because they are attracted to the pens of fish. To raise salmon, kilograms of other fish need to be used to feed the salmon, which has a significant effect on the environment. A devastating impact is sea lice on wild salmon. Sea lice proliferate on the salmon farms and attack baby salmon that are going to the sea.

Government Regulation

The FDA regulates Salmon farms. They supply funds into making the Salmon healthy and growing. The FDA also regulate the drugs that go into the Salmon through the food given to them by the farmers to make the salmon stronger, healthier and better for us.

Amendment 91

Amendment 91 protects Salmon from bycatch.

Amendment 91 is an innovative approach to managing Chinook salmon bycatch, It combines a limit on the amount of Chinook salmon that may be caught and has incentive agreements and performance standards. The program was designed to minimize bycatch and prevent bycatch from reaching the limit, while providing the flexibility to harvest the total allowable catch.

Ways of Mitigating the Effects of your Device/farm

A way to mitigate the effects is closed contamination of technologies. This will address the serious environmental problems by separating the farmed salmon from the marine environment. These closed systems can be used both on land and floating in the ocean.

What would happen if the government banned this type of commercial harvest? Is this fishing method/farm environmentally sustainable? Why or why not?

If the government banned this type of Salmon farming then people would have to rely on fishing in the deep ocean to get their salmon or in streams. Farms are an easier way for people to harvest Salmon for human consumption. This is a harmful and not sustainable method because there is an open net in the middle of the ocean that catches fish and also releases chemicals out into the marine life harming it.
