The length-weight relationship (LWR) and condition factor of the European eel Anguilla anguilla were investigated. A sample of 318 individuals was collected from Bardawil Lagoon, North Sinai from October to April 2020. The length ranged from 33.5 to 64.3cm for males and from 33.1 to 62.2cm for females. The results showed a negative allometric growth pattern for females (b=2.625) and an isometric growth (b=2.997) for males. The average values of Fulton's condition factor (CF) ranged from 0.178± 0.002 for the females, to 0.180± 0.002 for males. A slight decrease was observed in condition with an increase in body length for both sexes of eels. The present study provided the first reference on LWR and CF of the European eel from Bardawil Lagoon. These results contributed to the life-history parameters of the European eel which can help in the conservation and sustainability of these valuable endangered resources.
