Condition of physical and chemical parameters of tropical eel genus Anguilla habitat in Citarik and Cicatih rivers in the Cimandiri watershed, Sukabumi, West Java

Abstract

Land changes around the Citarik and Citatih rivers will affect the water quality. These changes will affect eels’ life (Anguilla spp.) as fish that live in the area. This study aimed to determine water quality (physical and chemical) and the presence of eels (Anguilla spp.) in the Citarik and Citatih rivers in the Cimandiri watershed Sukabumi, West Java. This research was conducted from April to May 2021. Data collection was carried out in the upstream, middle, and downstream areas of the Citarik and Cicatih rivers. The results of this study show that the Ciratik river has a turbidity of 53.3-93.6 NTU, current 0.448-0.478 m/s, temperature 25.55-26.65 °C, TDS 0.002 0.041 mg/l. Eels caught amounted to 13 individuals of (Anguilla Marmorata); Cicatih river had a turbidity 84.4-264 NTU, current 0.142-0.814 m/s, temperature 26.76-29.05 °C, TDS 0.079-0.096 mg/l, and eels caught amounted to 12 individuals of (Anguilla Marmorata). Based on the results, environmental changes in the Citarik and Citatih rivers are still normal, as evidenced by the water quality that is still following the needs of the eels and the presence of eels.
