Structure of the Fish Community in the Jatigede Reservoir Post Six Years of Flooding
Asian Journal of Fisheries and Aquatic Research, Volume 20, Issue 1,
Jatigede Reservoir began to be inundated in August 2015. The fish caught at the beginning of the 2017 inundation were 9 families consisting of 17 species in 2017. This research aims to determine the structure of the fish community living in the Jatigede Reservoir after six years of inundation. The research was carried out from November 2020 to April 2021 at the Jatigede Reservoir, using the survey method. Primary data which includes the relative abundance of fish, diversity index and fish uniformity. The fish sampling method used a purposive sampling method with 3 repetitions carried out at five stations representing the Jatigede Reservoir area. Data processing using Microsoft Excel to produce fish community structure in Jatigede Reservoir. The fish community structure in Jatigede Reservoir during the research consisted of 9 families, namely cyprinidae, cichlidae, eleotridae, bagridae, loricariidae, pangasiidae, zenarchopteridae, ambassidae and poeciliidae. At stations 2 and 3, it was categorized as stable with a moderate diversity index ranging from 1.08 to 1.73, moderate uniformity ranging from 0.56 to 0.83. At stations 1, 4 and 5 the fish community structure was categorized as unstable, with low diversity ranging from 0.57 to 0.97 and moderate uniformity ranging from 0.51 to 0.60.
