Sex ratio (male:female) was approximately 1:1.02. Length at maturity was 117 mm (males) and 120 mm (females). The fecundity ranged between 104 and 709 eggs, with egg diameter from 1 000 to 3 000 μm. The gonadosomatic and hepatosomatic index indicate that the species breeds during summer and winter. |
