Throughout the centuries fish has been an important component of the population’s diet in many parts of the world. Fish catches increased rapidly over the past hundred years due to improved technology, which provided more powerful engines and sonar equipment. This led to over fishing and caused a worldwide decrease in wild stocks. As a result, the growth in fish catches stopped some 20 years ago. The need to increase fish production by farming became therefore an urgent matter.
As in agriculture, fish farming techniques include:
# Removal of unwanted plants and animals
# Replacement by desirable species of fish
# Improvement of these species by crossbreeding and selection
# Increase of nutrient availability by the use of fertilizers and feeds
Advantages of fish farming
Fish provides high quality animal protein for human consumption.
A farmer can often integrate fish farming into the existing farm to create additional income and improve its water management.
Fish growth in ponds can be controlled: the farmers themselves select the fish species they wish to raise.
The fish produced in a pond are the owner's property; they are secure and can be harvested at will. Fish in wild waters are free for all and make an individual share in the common catch uncertain.
Fish in a pond are usually close at hand.
Effective land use: effective use of marginal land e.g. land that is too poor, or too costly to drain for agriculture can be profitably devoted to fish farming provided that it is suitably prepared.
