To many fish in the sea dating
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.
One example of this was the Pacific oyster in the UK, which was introduced into its waters in the 1960s via aquaculture with the idea that it would be a more commercially viable species than the native oyster.
Unfortunately, these pacific oysters have spread and created reef formations, forcing out the native oysters and altering the marine environment.
Since farmed fish often have been bred via selective breeding they have a lower genetic variation than wild fish.
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).
Like commercial farming operations on land, the density of fish in these pens necessitates certain chemicals to keep animals from getting sick and to keep things clean.
Tilapia is one of the most common types of farmed fish.
They are now seen as a nuisance, as they are one of the “most invasive species known and difficult to get rid of once established,” says Aaron Mc Nevin, a WWF biologist.
In Lake Apoyo in Nicaragua, tilapia escaped from a fish farm and their pollution and feeding reduced the lake’s quantity of an aquatic plant called charra, which was an important source of food for the lake’s native fish populations.
We have all heard the recommendation to eat more fish and seafood. Because fish, especially oily fish like salmon, are a rich source of Omega-3 fatty acids DHA and EPA which may help protect the body against heart disease, high blood pressure, inflammation, brain health, diabetes, digestive disorders and even autoimmune disease.
My family loves seafood, but there are some considerations regarding fish farming I try and take into account before purchasing and preparing it.
