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.(17)Unfortunately, not all fish are created equal as commercial fish farming practices have affected many fish populations and changed the fish supply substantially.It can also be difficult to find quality seafood and decipher labels to know where they were sourced.This density of fish creates problems like disease and pollution.
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 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.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.
Among the many labels are wild-caught and farm-raised.
