The investigated species included three members of the order Cypriniformes-Barbus luteus, Barbus sharpeyi and Cyprinus carpio (common carp)-and one species of the order Perciformes, Liza abu. A total of 520 fish specimens were collected between December 2021 and May 2022 from two sampling stations in Hor Abu Zarik. All sampling activities were conducted during daylight hours using a cast net, which is locally recognized as one of the smallest traditional fishing nets. Morphometric measurements of the sampled fish were recorded and both condition factor and feeding intensity were evaluated. The results demonstrated that Barbus luteus and Barbus sharpeyi collected from the second sampling station exhibited the highest condition factor values among all studied fish species, reaching 2.27 and 2.03, respectively. In contrast, the condition factor values of Liza abu from both stations were relatively similar. Likewise, the condition factor values of Cyprinus carpio showed only slight variation between the two stations. Regarding morphometric characteristics, Barbus sharpeyi specimens collected from the second station exhibited greater body length and weight compared to those collected from the first station, whereas Liza abu specimens showed relatively similar length and weight measurements at both sampling locations. 12 30 2025 12 30 2025 11 15 10.66590/jabs2025020202 https://lquestpub.com/article/10.66590/jabs2025020202
