The biggest individual of S. rivulatus was caught in Akbuk Bight, Gokova Bay (Southern Aegean Sea) at 15 m depth with trammel nets on 29.01.2018. Specimenof marbled spinefoot was 27.1 cm in total length and 414.8 g in total weight. The specimen was female with a gonad weight of 2.43 g and it was determined to be 9 years old.
