Description of life cycle and mating behavior | A maternal mouthbrooder (Ref. 118638). Males construct territories in shallow water; where there was ample space they were similar in structure and grouping to those of Oreochromis variabilis, each territory consisting of a central raised mating platform in the middle of a large circular depression; males occupy these territories at sunrise, when water temperature was 12°C and they left for deeper water in the late afternoon when the temperature rose to 25°C (Ref. 2). It exhibits pseudo-spawning and then true spawning follows (Ref. 2). |
