The tilapia (Oreochromis & Tilapia sp.) is a freshwater fish
which is cultivate now everywhere in the world and also in Ecuadorr.
It's a very robust and prolific fish. They are
oral incubators; the females keep their eggs in mouth after the fertilization
and later, the fry hides in it in case of danger.
The breeding of tilapia has been first a rural pisciculture to produce
cheap animal proteins for local populations of the developping countries
but now this fish have much more demand on the international market.
To prevent the reproduction of the tilapias during the grow-out, only
the males should be raised. The sex reversion is a technique which makes
possible to produce monosexual populations of only males.
The differents stages of the tilapia production
are: reproduction, harvest of the fry, sex reversion and the grow-out.
The tilapia can be raised in low density, in polyculture with other
species or in super-intensive with very high density, aireation and
water renewal.
In the same way that poultry farming, there is a large variety of genetic
lines of tilapia which allow to raise the fish best adapted to your
environment.
