A fish farm is a place where fish are bred. In most cases, this is done for food . There are two basic types of fish farms:

• Those where the fish are raised in tanks
• Those where fish are raised in specially prepared areas of the oceans , lakes or rivers .

The most common fish species raised by fish farms are salmon , carp , tilapia , catfish and cod . ^[1]

There are many problems related to fish farming:

• Sometimes fish can escape. This is only an economical impact if the fish also occur naturally, but can have a big impact if they do not.
• The fish in the farms need to be fed, for this other (smaller) fish need to be raised.
• Diseases and parasites may be a problem, because they spread much easier
• Fish farms have a bad effect on the surrounding habitat
