Abstract
Changes in fish fauna, fish conditions and some physico-chemical features of water of Lake Ula which was established for irrigation purposes and subjected to introduction of non-native fishes were investigated. Six different fish species were found, five of them belong to Cyprinidae family; common carp Cyprinus carpio L., 1758, gibel carp Carrassius gibelio (Bloch, 1782), goldfish Carassius auratus (L., 1758), chub Squalius cephalus (L., 1758) and gizani Ladigesocypris ghigii (Gianferrari, 1927). The other species found was eastern mosquitofish Gambusia holbrooki Girard, 1859 from Poeciliidae family. Fulton's body condition values varied between 0.99 (chub) and 1.48 (gibel carp). Two Carassius species (non-native species) had significantly higher condition values than those of other species (P0.05). Some physico-chemical features of water were compared and no big differences were detected between 1998 and 2009.
