Case
Fruit-waste aquafeed
A controlled feeding trial with Lingnan University tested fermented fruit waste as a feed additive for gilthead seabream.
Weight gain by week 10, against control
Glutathione reductase, against control
Malondialdehyde, a marker of oxidative damage, against control
The trial
The project is funded by the LNG-Fisheries Enhancement Fund (project FEF23101). Lingnan University ran a six-month controlled feeding trial in which gilthead seabream were fed a diet with fermented fruit waste added, and compared with a control group. Dr Jack Chi-Ho Ip leads the work, and Wong Chin Ming is a named collaborator.
The results
By week 10, treated fish had gained 20.3% more weight than the control group. Glutathione reductase, an antioxidant enzyme, was 96.4% higher. Malondialdehyde, a marker of oxidative damage, was 83.4% lower.
Why it is here
This is the aquaculture application of the same prebiotic approach the farm uses on its crops.
What we do not claim
- The trial species is gilthead seabream. The result has not been shown for the species Hung Yat ships.
- It is reported separately from the tomato leaf-spot result, which ran on a different crop and timeline.
