Abstract

Indonesia has many freshwater fish species but not recorded with completely, one of them from Banten Province especially in Pulosari Mountain areas of Pandeglang Regency. This study aimed to assess fish diversity, abundance, local distribution, potency, species status, bioecology aspects, and habitat condition. The study was conducted in September 2015 using survey methods. The site study was divided in five stations, the fishing gear mainly electrofishing and completed by cast net with diameter 2.5 meter. The operational of fishing gears using CPUE (catch per unit of efforts). Fish sample counted based on number of species and number of individuals for each species, then preserved and identified. Specimens were deposited in the Museum Zoologicum Bogoriense (MZB) Cibinong. The results recorded 12 species belonging to 11 families. St.2 (Cilagra river) is the most diverse with 8 species, following St.4 (Cijeruk lower) with 7 species.Barbodes binotatusis the most dominant species (19.2 ind./St.) and also widespread (100%). Two introduce species were found i.e.Poecillia reticulataandOreochromis niloticus. Based on potency almost balance both consume and ornamental fish. The inland waters in these areas were suitable for fish habitat.

Highlights

The Indonesian fish diversity is high in terms of freshwater fish, Kottelat et al [1] reported at least 900 species from west Indonesia and Sulawesi
The fish diversity among Indonesian islands were reported by Kottelat et al [1] that Java 132 species lower compare to Sumatra with 272 species and Kalimantan with 394 species
Fish species number of Pulosari Mountain is similar with Sawal Mountain areas in Ciamis Regency [23]

Summary

Introduction

The Indonesian fish diversity is high in terms of freshwater fish, Kottelat et al [1] reported at least 900 species from west Indonesia and Sulawesi. The fish diversity among Indonesian islands were reported by Kottelat et al [1] that Java 132 species lower compare to Sumatra with 272 species and Kalimantan with 394 species. The diversity and abundance of fish species tend to fall compared to the previous conditions like in Ciliwung and Cisadane [5]. It is caused by various factors, such as forest loss, water pollution, disturbance arising from the construction of dams, and over-exploitation [6]
