What are the types of fish cultivation?
Freshwater aquaculture is carried out either in fish ponds, fish pens, fish cages or, on a limited scale, in rice paddies.

Fins and tails become worn and damaged as the fish rub against the cage sides or each other. Crowding and confinement can cause the fish to suffer stress, which in turn makes them more susceptible to disease. Wave after wave of serious disease outbreaks have caused the deaths of millions of farmed salmon.
Why fish farming should be banned?
Fish farming is harmful to wild fish Faecal matter reduces the oxygen level in water. There has also been interbreeding between escaped and wild fish, weakening the wild stock. To avoid these problems, fish farming should either be banned or be subject to much stricter environmental controls.
What if we stopped fishing?
