Abstract

Abstract: Yellowfin parrotfish Scarus flavipectoralis has a wide distribution in Indo-Pacific waters which has an important ecological role in maintaining the balance of coral reef ecosystems, as well as having important economic values that need to be managed sustainably. This study aims to analyze the sex ratio, gonad maturity stage, and the size at first maturity. This study was conducted on a population of yellowfin parrotfish in the Wallace line at Spermonde Archipelago, South Sulawesi. Fish samples were obtained from catches of fishermen who were landed at the Rajawali Fish Landing Area of Makassar City. The results of this study indicate that the sex ratio of yellowfin parrotfish not balanced between male and female, there was more female than male; the development of gonad maturity stage is synchronous between male and female; and the size at the first maturity sexual of yellowfin parrotfish female was 18 cm and the male was 21.7 cm.
