Length-weight Relationship, Condition Factors, and Reproductive Biology of Kissing Gourami (Helostoma temminckii) from Celikah Swamp, Ogan Komering Ilir

Kissing gourami (Helostoma temminckii) is one of freshwater fish species that has a high economic value in Indonesia. This study aims to assess the length-weight relationship, condition factors and reproductive biology of H. temminckii from Celikah floodplain, Ogan Komering Ilir Regency, Indonesia. This study was conducted from July to September 2024 (dry season). The sampling site was determined using purposive sampling technique based on the catch area of local fishermen. A total of 64 H. temminckii samples were used in this study. Measurements of total fish length, weight, and fish dissection were conducted at the Fisheries Laboratory of the Universitas Islam Ogan Komering Ilir Kayuagung. The results showed that the total length of the fish obtained ranged from 12.2 cm to 17 cm, and the weight ranged from 34.1 g to 96.6 g. Most total lengths ranged from 12.1 to 13 cm (30.4%), and least from 16.1 to 70 cm (4.6%). Fish weights ranged mostly from 40 to 50 g (34.9%) and least from 90 to 100 g (1.6%). The length-weight relationship analysis showed that the a-value was 0.0389, the b-value was 2.631, and the R²-value was 0.3669. The growth pattern of H. temminckii in this study is negative allometric. The sex ratio in this study was 1:3.7, with 14 males (21.2%) and 52 females (78.8%).
