Fish Farming

Fish farming on the lakes of the Brenne regional natural park has been carried out for hundreds of years, since the practice was introduced by monks.

The method has remained unchanged for centuries, and is run over three separate lakes, with a three year cycle: the fish are transferred from one lake to another at the end of each of the three years, with the lakes and the fish getting larger each time.

Finally, the lakes are emptied of their water and netted during the winter. Because the lakes in this area are usually in a chain along the same water course, the bottom-most lake must be emptied first, and then the next, and so on, with each lake being filled with the water from the one above. The top-most lake fills up from rainwater.

The total annual production of the park is 1,200 tonnes, and the main species produced are carp (65%), roach and tench (31%), and pike and zander (4%).
