Keanekaragaman Arthropoda pada Tambak Silvofishery yang Terbengkalai di Desa Tanjung Rejo Kecamatan Percut Sei Tuan

Abstract

Sea water ponds are a man-made ecosystem, which is land near the coast that is dammed with surrounding dikes to form a pool of brackish water. During the last few years, research examining the diversity of arthropods in the abandoned silvofishery pond area in Tanjung Rejo Percut Sei Tuan Village has never been reported. Therefore the authors feel the need to conduct research to determine data on the diversity of arthropods (mainly from the crustacean class) in the abandoned silvofishery pond area in Tanjung Rejo Percut Sei Tuan Village. The purpose of this study was to determine the abundance and diversity of arthropods in abandoned silvofishery ponds in Tanjung Rejo Village, Percut Sei Tuan District and their relationship with the physics and chemistry of the waters. The research was conducted in July and October 2021 and data collection on vegetation and arthropods was carried out in situ. The results showed that there were 13 species found with a total of 134 individuals and an arthropod density of 7.44 ind/m² in pond I, and in pond 2 of 7.14 ind/2 . The arthropod diversity index in each pond has a different value, namely 2.32 in pond I, and in pond II it is 2.21. The PCA analysis results obtained showed that the diversity of arthropods at the study site had a positive correlation with mangrove density, salinity, pH, and temperature.
