Fish conservation status in eastern part of segara anakan Cilacap Indonesia

Abstract

Abstract Segara Anakan is an estuarine ecosystem located on the southern coast of Central Java Province which is very fertile with high biodiversity. However, the current condition is thought to have experienced a decline in biodiversity caused by sedimentation, overexploitation and water pollution problems so that it is feared that it will disrupt the preservation of organisms including fish. The purpose of this study was to determine the diversity of fish found in Segara Anakan Cilacap, and to know the conservation status of each species of fish caught in Segara Anakan in eastern Cilacap. This research was conducted using a survey method with cluster random sampling technique at 6 stations (3 stations on the Sapuregel River and 3 stations on the Kembangkuning River) with 3 replications each during highest tide. Fish collection is done by using a net and gillnet or gillnet that is installed during low tide and carried out during high tide. The diversity of fish in the waters of Segara Anakan is 36 species from 25 families. There are 16 species from 15 families in the Donan River and 34 species from 25 families in the Sapuregel River. The diversity of fish in the Sapuregel River is higher than in the Donan River. The status of fish in the eastern Segara Anakan waters management area is mostly in the LR (Least Concern) or low risk status and 1 NT (Near Threatened) species or threatened with extinction namely Sidat Fish (Anguilla bicolof)
