Most of our tilapia supply is imported from Latin American and Asia, and in 2015, Americans ate 475 million pounds of tilapia.

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!

If populations of non-native species become established they compete with native populations for resources such as food and breeding sites.

(8)Since farmed fish are selected and bred for certain genetic criteria like size, quick growth and hardiness, escaped species can become invasive, which has been recognized as one of the main causes of global biodiversity loss.

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.The amount of pollution from fish farms also depends on how the fish are contained.Open-net, or pen systems, allow for a direct exchange of water, where as “closed contentment” methods have a barrier which filters the water.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.
