The gametogenic cycle of Ostrea edulis and Crassostrea gigas was studied in the outflow water of fish ponds in Eilat, Israel. Despite relatively high water temperatures (14-28°C) and high salinity (41 ± 2 ppt), both species developed gonads. O. edulis spawned from March to May, when water temperature ranged from 18 to 22°C, with a dormant period during the summer months. C. gigas spawned between May and August, when water temperature ranged between 20 and 26°C, with a dormant period between August and April. Spat never developed in the fish pond system.
