The reproductive biology of the invasive blue crab Callinectes sapidus was studied in Thermaikos Gulf (Northwest Aegean Sea, Eastern Mediterranean). In two-year survey, 5698 (2897♂/2801♀) crabs were caught with use fyke nets. Total sex ratio (♂/♀) reached equality (1.03:1). female exhibited a protracted period. Mature and ovigerous females exhibit short migratory movements from estuarine inshore waters, where population mostly congregates (0–3 m), move to slightly deeper waters (1–3 m) up 9 m for spawning. A total 340 caught. Their number varied both spatially temporally; they observed 7-month period (April October) clear peak July–August at 3 depth gradient corresponding ≈60% years. Size first sexual maturity (CW50) estimated 113.1 mm CW. Average fecundity ≈790,000 eggs. Experimental trawling showed that (<1 estuaries serve as nursery areas juveniles. Defining spatiotemporal bathymetrical distribution any invaded coastal habitat could be considered key information implementation management policy species.
