Salmon farming is a big business and Norway and Chile are the leading producers of farmed salmon. The industry makes billions of dollars, but issues like diseases, fish deaths, and parasites are becoming hard to control.

In Norway, farms like Norlock are trying to reduce the number of sick fish. They use chemicals, freshwater baths, and even lasers to kill parasites. But even with these new technologies, salmon farming has a lot of problems. Farmed salmon often escape from the nets and can spread disease to wild salmon.

In Chile, salmon farms use large amounts of antibiotics to fight diseases, but this can also harm the environment and human health. Some salmon farms are trying new methods, like closed aquaculture, where they keep fish in tanks instead of in open water. This could help make salmon farming more sustainable in the future.

Difficult words: parasite (an animal or plant which lives on another animal or plant and feeds from it), escape (to get free from a place), antibiotic (a medicine which destroys bacteria in the body).
