Abstract

Bardawill lagoon is one of the most important lagoons in Egypt as a source of good quality fish and a habitat for wildlife. Monthly samples of golden grey mullet were collected from fishermen operating at various landing sites in Bardawil lagoon, North Sinai Egypt, during the fishing season 2020- 2021. Some biological aspects were studied such as the relationship between length and weight and the condition factor (K) were studied. For in Chelon auratus lengths ranged from 14.5–33.8 cm and total weight ranged between 27.0 – 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 sexes combined, males and females, respectively. The highest condition factor was observed in October. The length at first capture Lc= 19.20 and 20 cm for females and males, respectively. The objective of this study is to determine current biological status of this species in Bardawil lagoon
