Description:
This study focused on population structure, biodiversity, and abundance of the Chitgar Lake fishes in October 2014. Based on the lake location fishes samples were collected at 34 stations in water body. In this study identified 8 family belong to 18 species comprised of Cyprinidae (11 species), Cichlidae (one species), Loricariidae (one species), Pangasiidae (one species), Serrasalmidae (one species), Poeciliidea (one species), Salmonidae (one species), and Scaridae (one species) were Identified. Among the fishes just one native fish from Capoeta bohsei species observed during the study. The dominant lake fishes were invasive species Hemiculter leucisculus, Alburnus hohenackeri, Carassius auratus, Carassius gibelio and Pseudorasbora parva. The highest abundance of fishes were H. leucisculus 62 % and A. hohenackeri 35 % by Seine net. Furthermore, those were dominant abundance (69 and 12 % respectively) in Gill net method. Finally in Cast net method A. hohenackeri 38 %, Pseudorasbora parva 21 % and H. leucisculus 17 % were dominated in the shore region. The lowest fishes abundance were P. hypophthalmus and Parrotfish. Overall more than 90 % of the fishes population were invasive and alien species. Thus, the present of invasive fishes and predator fishes luck in the Chitgar lake might be reason for ecosystem ruin, algae bloom, feed competitive, fish disease and trophy level rises.
