Fish farms support sustainable fishing. How can fish farms support the number and diversity of fish?
In fish farms, the owners will select which fish will mate. We call that selective breeding. What problem does selective breeding cause?
Will the diversity of species within fish farms increase or decrease?
Fish farms do not catch wild fish. That supports biodiversity of wild fish. However, fish farms do carry out a lot of selective breeding and that leads to decreased biodiversity in the fish farm fish.
