The study aims to determine the reproductive characteristics of Siganus luridus along the Turkish coast.
181 female Siganus luridus were sampled from Gökova Bay using trammel nets, angling, and trap fisheries between July 2019 and June 2020.
Gonadosomatic index and gonadal histological analysis were conducted to assess reproductive parameters.
Reproduction starts in May, peaks in August, with gonadosomatic index variations showing highest spawning ready females during this period.
Absolute fecundity ranges from 98,607 to 801,460 oocytes per female, relative fecundity averages 1,734 ± 747 oocytes g⁻¹.
Condition factor highest in April (1.67 ± 0.11) and lowest in September (1.39 ± 0.11).
