GIFT "Genetically Improved Farmed Tilapia": All Male Tilapia Fingerlings with Greater Yield and Uniformity

Greater yield and uniformity in tilapia farming

Mono-sex tilapia farming is a bit more complicated but it's worth it. It allows for mostly male tilapia to be grown, sometimes up to 98% male. This is done using methods like picking out males and females by hand, using hormones, or natural methods. Using specially bred tilapia (GIFT) is best for commercial farming. Using hormones can change most fish from female to male, usually about 98% of them. Another method uses changes in temperature after the fish hatch, turning about 86% of them into males. The natural method gives you all-natural males. It's important to know that with hormone-treated fish, some might look like males but genetically they're still females.

Problem

  • Low and uneven yields: Mixed-sex tilapia farming leads to frequent reproduction, reducing production yields and resulting in non-uniform fish sizes at harvest.
  • Slow growth and feed conversion: Female tilapia use substantial metabolic energy for reproduction, slowing growth and reducing the conversion of feed into body weight.
  • Lower production returns: Smaller and slower-growing fish reduce marketable output and profitability for tilapia producers.
  • Inefficient male stock selection: Manual sex selection is time-consuming and can result in discarding nearly half of the available fingerlings, reducing the stock available for production.

Solution

  • Higher and more uniform yields: All-male tilapia stocks limit reproduction during grow-out, resulting in larger, more uniform fish and higher yields per unit area.
  • Faster growth and feed conversion: Male tilapia channel more metabolic energy toward weight gain, supporting faster growth and more efficient conversion of feed into body weight.
  • Improved production performance: GIFT uses selective breeding of carefully monitored brood parents to improve production traits, increasing the performance and value of farmed tilapia.
  • Productive male fingerlings: GIFT all-male fingerlings provide producers with improved male stocks for grow-out, reducing reliance on manual sex selection at farm level.

Scaling Readiness describes how complete a technology's development is and its ability to be scaled. It produces a score that measures a technology's readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

  1. Selecting Broodstock:

    • Begin by choosing mature and healthy broodstock, preferably males and females, from a reliable source.
  2. Stocking Spawning Units:

    • Place the selected broodstock into separate spawning units, such as tanks or hapas, about 15 days before the spawning season.
  3. Feeding and Temperature Control:

    • Provide regular feeding for both males and females in their respective units. Gradually raise the water temperature up to 26°C.
  4. Monitoring Ovulation in Females:

    • Keep a close watch on female broodstock for signs of ovulation. When they carry eggs in their mouths, it's time to proceed.
  5. Egg Collection and Incubation:

    • Gently collect the eggs and transfer them to designated hatching jars. Incubate until hatching occurs, which typically takes around 10-12 days, depending on the temperature.
  6. Transferring Fry to Rearing Units:

    • Move the newly hatched fish, known as fry, from the brooder basins to rearing units.
  7. Hormonal Treatment (Optional):

    • If using hormonal alteration for mono-sex production, mix α-Methyltestosterone with fry feed. Ensure continuous feeding for 21 days to achieve a male rate of around 98%.
  8. Ensuring Proper Size Distribution:

    • After treatment, ensure there are only a few fry under 14mm in size.
  9. Selection and Management of Broodstock for Future Cycles:

    • For ongoing production cycles, continue to select and manage high-quality broodstock. These should be younger, weighing at least 300g, and free of wounds and parasites.
  10. Provision of Adequate Resources:

    • Ensure access to clean water, free from pollutants, and install aerators for oxygen supply. Provide hapa-style nets to raise the fingerlings.
