Growth Performance of Milkfish (Chanoschanos) Fed Plant-Based Diets
The high cost of fish feeds is the biggest problem in milkfish production caused by the protein from the expensive fish meal. Looking for an alternative from the agricultural commodities is imperative. This paper evaluates the nutritive composition of plant-based formulated feeds utilizing breadnut, breadfruit and banana peelings and their effects on the growth performance (weight gain and length increased) and, survival rate of milkfish. Results showed that the three formulated feeds have lower protein levels (19.9, 19.6, 20.35) but with extensively higher fat contents (24.4, 15.72, 10.75) than the commercial feed (27.1%, 4%). The samples’ growth responses have no significant difference (p < 0.05) among the four feeds. Thus, the plant-based formulated feeds have the potential to contribute to the growth of milkfish comparable to the commercial feed. Further, the agricultural products used in the formulations are feasible for the replacement of fishmeal and must be promoted for utilization in feed production.
