Study Notes
Tilapia Breeding and Growth
- Tilapia species are divided into two groups based on their breeding behavior: Mouthbrooders and Substrate Spawners.
- Mouthbrooding tilapias, like Oreochromis mossambicus, are known for their parental care. The female carries the eggs in her mouth until they hatch.
- The Oreochromis mossambicus variety exhibited poor growth characteristics.
- This led to the hybridization of Oreochromis mossambicus with faster-growing tilapia species like Oreochromis niloticus and Oreochromis aureus.
- This resulted in hybrid tilapia strains that inherit desirable traits like fast growth and cold tolerance.
- Hybrids have been developed to combine the best qualities of different species. For instance, Oreochromis niloticus x Oreochromis aureus hybrids boast the fast growth rate of O. niloticus and the cold tolerance of O. aureus.
- Tilapia fingerlings reach a weight of 15 to 25 grams, ready to be transferred to production ponds or cages.
- Tilapia are commonly raised in earthen ponds, cages, concrete tanks, and integrated with terrestrial crops.
- Duck rearing in an extensive system, where ducks are raised in tilapia ponds, is another common practice.
