| Abstract | ||||
| The Bogue, Boops boops (Linnaeus, 1758), is one of the common and economically important demersal species in the Egyptian Mediterranean waters. A total of 1,725 specimens were collected from the Egyptian Mediterranean waters off Alexandria between January and December 2023. The length range varied from 6.7 to 22.8 cm total length, and the total weight ranged from 2.12 to 128.32 g. Otoliths were used to determine the age of the specimens, revealing that the fish ranged in age from I to IV years, with the maximum age recorded as 4 years. The length-weight relationship was calculated as W = 0.0052 * L³.²⁰², indicating a positive allometric growth pattern. Growth parameters of Boops boops were estimated using the von Bertalanffy growth function (vBGF) as follows: L∞ = 31.6 cm, K = 0.238year⁻¹andt₀ = -1.473year.Monthly analysis of the maturity stage distribution for females showed that Boops boops has a long spawning season extending from January to April, with the peak in March. Length at first sexual maturity (Lm50) was found to be 14.2 cm. This study provides essential insights into the age, growth, and reproductive parameters of Boops boops, offering valuable information for future research and the development of effective fisheries management in the Egyptian Mediterranean. | ||||
