| Abstract | ||||
| Length frequency distribution, weight-length relationship, Fulton's, and relative condition factors of the common sole (Solea sloea) in Lake Manzalah were investigated. The fish was caught by trammel nets from the northern region of Lake Manzalah near Bughaze El-Gamil where the marine species were found. The results of the length-weight relationship for 361 common soles showed a positive allometric growth (W= 0.0029 L3.3777) indicating the suitability of the area for the species growth. The mean value of the relative condition factor (Kn) of the common sole was 1.013, while the average value of Fulton's condition factor was 0.911. These values suggested a good condition in the northern Manzalah lake for Solea solea. Such results may be helpful for S. Solea management. It's worth mentioning that during the study period, only two Red Sea hardyhead silverside fish (Atherinomorous forskalii) of 9.4 cm were recorded. Therefore, more extensive studies are needed to assess the actual status of marine fish and to manage the fishery of common soles at Lake Manzalah. Also, a monitoring program should be established to detect any ecological and biological changes after deepening and cleansing processes. | ||||
