In 2009 Americans consumed 15.8 pounds of fish and shellfish per person, 4.833 billion pounds of seafood in total.Per week, Americans eat about 3.5 ounces of seafood, which is still only half of what the USDA recommends.

If they interbreed with the wild fish it can result in a less genetically diverse, and therefore less robust, population. For example, Atlantic and Pacific salmon belong to different genera and while they can produce offspring, those offspring will be unable to reproduce (like mules).

(12, 13)Modern fish farming practices often raise fish near the top of the food chain (affecting populations of fish that eat or are eaten by these species) and contain thousands of fish in tiny pens (similar to commercial chicken or cow operations).

As you may imagine, these conditions leave something to be desired and affect both the quality of the fish and the health of the ocean.

Another way aquaculture can have a negative impact is by introducing farmed species into the wild and therefore changing the biodiversity of aquatic ecosystems.

Even when measures are taken to prevent escapes, predators like birds and sharks, equipment failure, human error, severe weather and other complications mean that escapes of farmed fish are inevitable.
