Title: Effects of Using Different Diets in the Growth Performance of Mangrove Red Snapper Lutjanus argentimaculatus

Abstract

The mangrove red Snapper (Lutjanus argentimaculatus) is a high-value marine fish and ideal culture species. The study was conducted to evaluate the growth and survival rate of mangrove red snapper fed with different diet types. The study was laid out in a randomized setup using three (3) treatments: Treatment 1- Trash fish, Treatment 2- Golden apple snail, and Treatment 3- Fiddler Crab using One- way ANOVA as a statistical tool. Based on the result of the study, mangrove red snappers fed with Trash fish gained the highest growth rate in terms of length, width, and weight of 8.89 cm, 2.19 cm, and 63.46 g. However, samples fed with fiddler crab (T3) obtained the lowest growth rate in terms of length, width, and weight of 3.72 cm, 1.06 cm, and 43.86 g. This study demonstrates that the samples got a 100% survival rate regardless of the treatment used. Furthermore, the result showed a significant difference in the growth rate of Mangrove Red Snapper in terms of length F=2100.544, width F=175.280, and weight F=319.770 with P<0.0001. Therefore, it was concluded that the use of trash fish (halfbeak and scalloped perchlet) is effective as a feed for the growth and survival of the Mangrove Red Snapper
