Studies on Crustacean Diseases of Seabass, Morone Labrax, in Suez Canal, Ismailia Governorate

The present study was carried out to detect the parasitic crustaceans affecting marine seabass Morone labrax that collected seasonally from different areas of Suez Canal (Ismailia province). There were no pathognomic signs in infested fish. Some revealed signs and P. M. lesions as bulging of opercula, hemorrhages, abrasions and ulcers on skin, sluggish movement and emaciation. The crustacean parasites were identified as copepods of Lernanthropus psciaenae and Caligus carangis. The total prevalence was (47%) and the summer displayed the highest seasonal prevalence. The relation between fish body weights, lengths and infestation rate were also studied. [Eissa I A M, Maather El-Lamie & Mona Zakai.
