Evaluation of Application Floating Net Cage Aquaculture Systems Integrated Multi Trophic Aquaculture (IMTA) and Monoculture an Based Growth Rate Silver Pompano (Trachinotus blochii, Lacapede)

Sea Farming is a part of the KepulauanSeribu region where aquaculture activities are officially permitted by local government. The purpose of this study is to assess the growth rate of silver pompano (Trachinotus blochii, Lacepede) and examines the physical and chemical parameters and their relationship to Integrated Multi-Trophic Aquaculture (IMTA) and monoculture farming systems. This research was conducted in the area of the Sea Farming KarangLebar of the KepulauanSeribu, in two main locations. i.e., Site A was a fish farming area of IMTA system, growing up silver pompano (Trachinotus blochii) and tiger grouper (Epinephelusfuscoguttatus, Forsskal), and Site B was the area of monoculture, growing up silver pompano (T. blochii). Biotic data was analyzed using the growth rate of the fish, whilst abiotic data was analysed using two-way ANOVA test. The results of the study in both locations showed the growth rate of the fish with a pattern of positive alometric (b >3) indicating faster in the growth rate of fish weight than those in length. The physical and chemical factors indicated within the normal range of water quality criteria for marine life. Keywords: Floating Net Cage, IMTA, Monoculture, Silver Pompano (Trachinotus blochii)
