Length-Weight Relationship and Condition Factor Of Orange-Spotted Spine Foot, Siganusguttatus (Bloch, 1787), In Takalar, South Sulawesi, Indonesia

Abstract

This research analyzed the length-weight relationship and condition factor of orange-spotted spinefoot (Siganusguttatus) from Takalar District, South Sulawesi, Indonesia. Samples were collected from February to July 2018, in the seagrass and coral reef ecosystems of Laikang Bay and Tanakeke Island. The samples were analyzed in the Fisheries Biology Laboratory, Fisheries Department, UniversitasHasanuddin, Makassar. The 95 specimens collected from Laikang Bay comprised 61 male and 34 female fish, while the 1103 specimens from Tanakeke Island comprised 1066 male and 37 female fish. The regression coefficient (b) was in the range 1.482 – 3.099 for both male and female orange-spotted spinefoot. On average, the condition factor of male orange-spotted spinefoot was higher than that of females, except in the Laikang Bay seagrass ecosystem.
