Tilapia

Tilapia/Saint-Pierre is one, of cichlidés , including/understanding approximately 40 S originating in the Ethiopian zone. With the species of the kind Oreochromis , they set up the group of Poisson S named Tilapia S (vernacular name). More usually known however under the name of " Saint-Pierre" in France and other countries " St Peter' S Fish". The largest specimens of tilapia measure 61 cm and weigh 5,5 kg.

Certain species of Tilapia/Saint-Pierre already were introduced into certain plans of fresh water of Central America and of South Asia East because they show characteristics interesting for the type of breeding:

  1. a general-purpose food mode (planktivorous, vegetarian or omnivore);
  2. a food index of generally high conversion and a growth;
  3. a great resistance to the lack of oxygen, but not of air breathing (dipneuste);
  4. a fast and easy reproduction;
  5. a small degree of parasitism, which decreases the losses caused by a fall in growth rate and mortality;
  6. a flesh of good quality and affordable price;
  7. a tolerance with water at relatively high temperature.

The current production of Saint-Pierre/Tilapia is of 1,5 million T, primarily in China and Philippines.

Saint-Pierre/Tilapia raised in Belgium

The Aquafarm company decided to produce this tropical fish in Belgium which however needs warm water to live. The idea of this company is to re-use the warm water which leaves the tertiary circuit of the Nuclear plant of Tihange.

Reproduction

After a bridal parade the female lays approximately 200 ovules in the basin and the male fertilizes them. Eggs, then the young people, are kept in the mouth of the parents. Incubation lasts approximately two weeks. Can have 6 to 11 cycles of layings per years. Sexual maturity with 10g for the females, optimum with 40g.

Use

Saint-Pierre/Tilapia was established with the Vietnam in the Rizière S flooded to fight against the Paludisme: this fish nourishes larvae of mosquitos indeed. It can be then consumed.
