Length-weight relationships and condition factors of brackish water catfish, Mystus gulio (Hamilton, 1822) from three different estuaries, West Java, Indonesia

Abstract. Paujiah E, Dhahiyat Y, Herawati T, Iskandar, Haryono, Zulfahmi I, Fahri. 2023. Length-weight relationships and condition factors of brackish water catfish, Mystus gulio (Hamilton, 1822) from three different estuaries, West Java, Indonesia. Biodiversitas 24: 2855-2864. This study investigated the biometric catfish (Mystus Hamilton collected estuaries in Cianjur District, Java Province, Data (class interval, growth pattern, factor condition) were sorted based on time, location, season. Water quality parameters measured include temperature, conductivity, TDS, hardness, resistivity, pH, DO, total oxygen, ORP, salinity. The correlation between K-Value was analyzed using multivariate analysis. Our results showed that worth pattern M. allometric, with value ranging 0.904-1.042. There variations patterns according to fish sex. lowest values found August for males April females. Meanwhile, highest 4 June 2022 5 February NMDS analysis places resistivity conductivity a axis other environmental factors. our suggest District adequate supporting survival by providing food suitable habitat.
