around 15-20 farms use geothermal water and grow freshwater sea bream, Arctic trout, turbot

and Atlantic halibut.

1.1. The Examples of Fish Farming Projects Using Geothermal Energy

With the start of shrimp, lobster and fish farming in İZMİR Balçova Thermal Facilities in

Turkey, the thermal water fish farming technique, which has been applied in 16 countries in

the world and has become a serious sector in most of them, will be among the first examples
launched in Turkey with the implementation of this project. With the 50 square meter

insulated pool floor to be prepared in the garden of the facility and the system to be installed

on the walls, waste thermal water at 40˚C will be passed through the pipes and heated.
Production is planned to launch with freshwater shrimp and freshwater lobster (crawfish) as

well as carp, sea bream and sea bass.

Carp and eel are the most widely grown species in Japan. The most profitable is the eel. Eels

are grown in earthen pipes with a diameter of 25 cm and a length of 0.90 m. The water in the
pipes is kept at 23°C by mixing hot spring water and river water. The weight of adult eels

varies between 100 gr and 150 gr, and the annual total production is around 3800 kg. Various

kinds of crocodiles are also grown in geothermal waters for tourism purposes.
