The population of the world is increasing rapidly. By 2020, there could be 7.5 billion people on the earth. Will there be enough food for all these people? Some scientists think fish farming might solve this problem. However, other scientists worry that fish farming could bring serious environmental problems.

Fish farming is not a new thing. There were fish farms in China 3,000 years ago. Today, about one third of the fish we eat comes from fish farms.

Most fish farms raise plant-eating fish. Popular kinds of plant-eating fish are carp, tilapia, and catfish. However, many fish farms are starting to raise meat-eating fish. A popular type of meat-eating fish is salmon. However, it takes up to 5 tons of wild fish to produce just 1 ton of farm-raised salmon. So if this continued, many types of wild fish could become extinct.

Critics (评论家) of fish farming also say that farm-raised fish is unhealthy. They say there are dangerous chemicals (化学物质) in the fish. They also say fish farming pollutes the water. Some people say that the ways of farming being used now won’t produce enough fish anyway. Instead of building fish farms in lakes or near the coast, they say that the fish farms could be moved far out into the ocean. In the future, fish farms might be large cages that move to the ocean.
