Length-weight relationship and condition factor of the Thinlip Grey Mullet (Liza ramada) in the Bardawil Lagoon, North Sinai, Egypt.

A random sample of 273 fish of Mugilidae species the thinlip grey mullet (Liza ramada) was taken from Bardawil lagoon, North Sinai Egypt, from October to April during fishing season 2020/2021. The length-weight relationship, condition factor, and length at first capture parameters were analyzed. In the present study, the sizes for all individuals of Liza ramada ranged between 14.2 – 39.3 cm in length and 25 -503 g in weight. The length-weight relationship was W = 0.0173 L2.7695 (R2 = 0.9788), W = 0.0104 L2.9269 (R2 = 0.9836) and W = 0.0125 L2.8699 (R2 = 0.9813) for males, females and combined sexes of Liza ramada respectively. The value of b indicated negative allometric growth. In the present study, the condition factor of Liza ramada during this study was ranged between 0.67-0.94 in males, 0.71-0.91 in females, and 0.69-0.94 in combined sexes. The condition factor was high during (May, June, and July) and low during April.
