(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.
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.
This density of fish creates problems like disease and pollution.
The biggest source of pollution is the accumulation of fish waste and uneaten food beneath the sea pens which can degrade the quality of the surrounding water.
Open-net, or pen systems, allow for a direct exchange of water, where as “closed contentment” methods have a barrier which filters the water.(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.Among the many labels are wild-caught and farm-raised.
It’s tempting to opt for farmed-raised, as often the wild-caught fish cost twice as much!Aquaculture is the practice of raising fish or ocean plants for food or resources.
