(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.
If populations of non-native species become established they compete with native populations for resources such as food and breeding sites.
Fish farming is a way to create a much larger amount of fish much more quickly, cheaply and efficiently than with wild caught fish.
Unfortunately, when something seems to good to be true, it very often is!
(6)While aquaculture is nothing new as humans have been farming fish for millennia, there have been some substantial changes in recent decades.
There is evidence of fish farming dating back to 2000 BCE in China and depictions of ornamental fish ponds in ancient Egyptian paintings.
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.
In fact, around 50% of the seafood we consumes comes from aquaculture.
It is a billion industry which has grown 9% a year since 1975.
Another example of the negative effect of fish farming on native fish population and environment is with Tilapia.
Tilapia is one of the most common types of farmed fish.
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.
