Evaluation of Formulated Feeds for Genetically Improved Farmed Tilapia (GIFT)

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. Peelings and leftover materials are one of the cheapest nutrient sources that can decrease the elevated price of fish feed. 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: Sweet potato peelings (Boniatos) and the remaining mackerel scad fish bones (Decapterus macarellus) that do not compete with human consumption should be developed for use in the formulation of feed. The ingredients utilized in the feed formulations are possible substitution of fish feed and the advancement of its usage is commendable.
