Tilapia Breeding
Tilapia are prolific breeders. With the proper environmental conditions, tilapia can easily reproduce and provide ample fish for home consumption or for growout for commercial farms.
Tilapia are classified as either mouth brooders or substrate spawners.
Mouth Brooders
The members of the Oreochromis genus are maternal mouth brooders and are a common choice for aquaponics or aquaculture. In terms of popularity, the Nile tilapia (O. niloticus) is the most widely cultured tilapia, followed by Blue tilapia (O. aureus) and Mozambique tilapia (O. mossambicus).
The Oreochromis display an elaborate courtship behavior. After building a nest, the male aggressively repels other males that enter in proximity to the nest. When ready to spawn, the male displays a darkened color and leads a female to the nesting area. The fish then swim around the nest and the male will butt against the female genital area to induce egg laying. The courtship is often brief, lasting only a few minutes in many cases and seldom more than a few hours.
The female tilapia lay their eggs in pits (nests) and after fertilization by males, the female collects the eggs in her mouth (buccal cavity) to maintain them until hatching.
Tilapia Spawning (Oreochromis niloticus)
Other tilapia display different mouth brooding behavior. Sarotherodon galilaeus are biparental , with both parents brooding the eggs and defending the newly hatched fish.
The male Sarotherodon melanotheron is the parent that performs the mouth brooding, while the female leaves the nest.
Tilapia - How to Raise & Breed TilapiaWhether you're a seasoned aquaculturist or a novice, this in-depth manual is your key to unlocking the secrets of successfully raising and breeding tilapia. From selecting the right type of tilapia for your setup to implementing effective breeding techniques, Stephens leaves no stone unturned. With years of hands-on experience, he shares valuable insights into the intricacies of tilapia farming, providing a roadmap for both beginners and seasoned professionals. |
Tilapia Selective Breeding ProgramsTwo strains of Nile tilapia, Oreochromis niloticus, were developed through mass and pedigreed selection techniques. Performance of the mass-selected line has been tested against a control and commercial lines used by the farmers. On station testing indicated an improvement of 35% over the control, the base population, from which the selected O. niloticus stock was developed. The best candidates will be identified and used in the pedigree selection program. |
Substrate Spawners
Members of the Tilapia genus are substrate spawners. The male and females will build a nest and defend it together. A male and female will typically form a bonded mating pair and courtship can last up to a week, but usually takes place over several days.
Females will first lay their eggs in pits (nesting area) dug in the bottom of a lake or pond. You can simulate this condition in a tank by adding some substrate (e.g. gravel) which allows the tilapia to evacuate a nesting area. The male will then spawn and fertilize the eggs. After fertilization, the parents guard the eggs, chasing away predators and making sure proper aeration is maintained for hatching.
Tilapia rendalli and Tilapia zillii are two popular commercially-raised species that are substrate spawners.
