Abstract
Bungo fishis a fish that has fishery potential that is not yet widely known. Bungo fishis a fish that can be consumed that is low-fat and has high protein, which can also be used as an ornamental fish. This study aims to analyze reproductive biology which Includes genital ratio, gonad maturity level (TKG), gonad maturity index (IKG), size of first maturity of bungo fish gonad, Glossogoius giuris (Buchanan, 1882) in Lapompakka Lake, Wajo Regency, South Sulawesi. The research was conducted in September, October and November 2020. Fish samples obtained from the catch of 2 fishermen using bubu fishing gear. Analysis of fish samples was carried out at the laboratory of Fisheries Biology, Department of Fisheries, Faculty of Marine and Fisheries Sciences, Hasanuddin University, Makassar. The total number obtained during the study was 212 fish consisting of 153 male fish and 59 female fish. The results showed that the sex ratio of male and Female Bungo fish was 2,59 : 1. The gonad maturity level (TKG) of femaleand male Bungo fish was found at all levels (I - IV). The gonad maturity index (IKG) of female fish is 6,65% and male fish is 2,17%. The size of the first maturityof male gonads was 220 mm and females 172,68 mm.
