It is a mouthbrooder. The mating strategies can vary. Both uni-parent and bi-parent mouthbrooding is used, and monogamous or polygamous behaviour.[6]
Distribution and habitat
This widespread species is found in lakes, rivers and other fresh or brackish habitats in northern and central Africa (including
Behavior
Mating
Mating is usually
Male mate choice
An experiment studying mate choice in the mango tilapia shows results of the correlation between operational sex ratio, characteristics of the body and pairing. In this study, the fish were exposed to different OSR's (more males, more females, or an equal ratio). Pair bonding was formed quicker between larger fish, and there was a long delay in pairing for the most abundant sex in the OSR. In addition, this study showed that mango tilapia that mate within a similar size group have greater reproductive success.[6]
Male mating style flexibility and parental care
There is flexibility for male mango tilapia in their mating styles. During
For the mango tilapia, parental care is important for the survival of the offspring. Parents who shared the job of incubation had double the reproductive success of other parents who did the job alone. Rather, for uniparental parental care, the parent's reproductive success for each brood was 20% higher. In terms of the relationship between caring strategies and clutch size, either parent is equally capable of caring for its offspring (both capable of taking care of the same number of eggs and fry). Levels of parental care in mango tilapia depend on the costs and benefits of staying versus departing. Some costs of both males and females were the growth and prolonged time until the next time they reproduce. In addition, parental care decreased a female's future ability to reproduce (fecundity). This is plausible since a body weight increase increases fecundity. Female mango tilapia have high parental care costs, which can be thought to be separated in two parts: egg production cost and parental care cost. In experiments studying parents deserting their children, deserting was more frequent in males and females when there were higher parental care costs and males deserting was more frequent when there was a reduced benefits from parental care.[7][9][10]
