How to Earn Money with Fish Farming Part 3: Tilapia

Tilapia  is fish, which   lives  only from vegetables and cereals and the fry do not pass a planktonic phase.  Therefore it is a very good choice for us. Also the taste of the fish meat is very good.

Detailed information is given at:  http://www.appropedia.org/Tilapia_Fish_Farming_Notions

The main draw back could be, that Tilapia  need warm water, for which energy may be needed, when we live in cold countries. But using  solar collectors, to heat up the water, especially fresh water in separate vessels, should help, to minimize the needed energy.All water tanks and the fish tanks should be insulated of course.

If  a heat exchanger is installed in the house, then  two benefits can be combined:

• Reduce the energy demand to heat  the house
•  use the exhaust air to heat up the water tanks. In the exhaust air  is still enough oxygen for the fishes.
