Formulated Feeds for Genetically Improved Farmed Tilapia (GIFT)

Resti Tito Villarino

Background: The problem in the development of Genetically Improved Tilapia brought about by the protein from the expensive fish feed is the surprising cost of fish feeds. The study's aim is to look for an alternative and cheap fish feed. The research identified Genetically Improved Farmed Tilapia (GIFT) growth and survival rates in the HAPA using formulated sweet potato granules and commercial feeds as the grounds for the development of a Technology Guide. The experiment method has been used in the research.

Results: The findings showed that the three formulated feeds have lower protein (20.33, 19.3, and 19.6) yet with higher fat (24.1, 15.69, and 10.72) than the commercial (24.1%, 3%). The initial and final weight in grams, length in centimeters and width in centimeters were highest on T₁ then followed by T₂ and T₃. It was with the use of T₁ which proved to be an effective feed.

Conclusion: The ingredients utilized in the feed formulations are possible substitution of fish feed and the advancement of its usage is commendable.
