Summary In aquaculture laboratories which work with Nile tilapia (Oreochromis niloticus) reproduction and use crystalline water, is frequently necessary to verify whether the females are incubating orally the eggs. The identification of the females when there is not know-how is difficult and slow, and in most cases is stressful and damage the eggs. This study describes a simple technique, using a mirror, to identify Nile tilapia incubating eggs orally in crystalline water. The results showed that is possible to identify the females which are incubating orally with 100% efficiency.
