Information on transgenerational effects of cadmium (Cd) and zinc (Zn) within hour of exposure is scarce. To the end, larvae of marine medaka Oryzias melastigma at 0 day-post-hatching (dph) were subjected to LC(50) for 96-h of Cd or Zn for 0.5 and 6h, and then transferred into clear water for 95 days until the generation of offspring larvae at 25 dph. Growth, antioxidant capacity and stress response in offspring larvae were examined. Exposure to Zn for 0.5h or Cd for 0.5h and 6h promoted growth performance and reduced total antioxidant capacity (TAC) and activities of superoxide dismutase (SOD...
