Some biological aspects of marbled spinefoot (Siganus rivulatus) were determined from a
southern Aegean Sea small-scale fishery. A total of 721 individuals were captured (335
females, 279 males and 87 immature) and sex ratio was found to be 1:1.27, female to male.
Total lengths and ages of individuals ranged between 9.0–26.1 cm and 1–9 years.
Asymptotic length (L∞), growth coefficient (K) and the theoretical age at zero length (t0)
were estimated to be 27.7 cm, K = 0.162 y−1 and t0 = −1.87 y. Length at maturity value was
determined as 16.6 cm for females and 16.84 cm for males. Although S. rivulatus is one of
the target species for small-scale and recreational fishery in the Turkish coast of the southern
Aegean Sea, especially in Gökova Bay, official landing data is lacking for Turkey. Results of the
present study are of crucial importance for further fisheries management of this invasive
