Tilapias are just ordinary hardy fish that can be reared by anyone in the tropics who has even a very poor pond condition. Tilapia can be reared by people who are poor, illiterate because to rear them we do not need any special technical knowledge, maintenance is least costly, feeding is very easy and simple and they multiply themselves very fast and in great number, They can withstand most of the adverse conditions which are found in a poor small and marginal farmer's situation. Even the man who has only very little land and a very small pond or a tank can rear them for his own home use or for sale. Therefore, it can be said to be the poor man's aquaculture special fish.

Tilapia are warm water fishes though the optimum temperature range for their growth is found to be between 20 to 30 degree centigrade. The minimum temperature that it can withstand is about 12 to 13 degree centigrade and the maximum even up to 40 degree centigrade. Their respiratory demands (energy requirements through oxidation during respiration) are least and hence they can be reared in less oxygenated water. They can be easily transported from one place to other without caring much for them. Most of the special care euryhaline (chemically varying in nature) and withstand brackish water. They breed very easily and look after the young ones very well. Some of them keep their young ones in the mouth to protect them from any danger to which the young ones may be exposed

Though there are many species of tilapias some of them are more suited to economic rearing because of their high yielding nature. They are described here.
