Length-weight relationship, condition factor, and length at first capture of Chelon auratus (Risso, 1810) golden grey mullet in Bardawil lagoon, North Sinai.
: Some biological aspects such as length-weight relationship, condition factor, and length at first capture were studied for golden grey mullet Chelon auratus in the Bardawil lagoon during the fishing season 2020- 2021. Chelon auratus lengths ranged between 14.5–33.8 cm, and total weight ranged between 27 – 237.20 gm. The total length - total weight relationship was estimated as TW= 0.0257 TL2.652, TW= 0.0344 TL2.5296, and TW= 0.0239 TL2.652. for both sexes combined, males and females respectively; with (b) value >3. The highest condition factor was observed in October for both sexes, but by size group, it was found 24-24.9 cm for males also 16-16.9 and 22-22.9 cm for females have the highest condition factor. The length at first capture were found Lc= 19.20 and 20 cm for females and males, respectively. The objective of this study is to determine the current biological status of this species in the Bardawil lagoon.
