Abstract
Extrinsic estradiol-17β (E2) is an environmental hormone. Female fish exposure to waterborne E2 might affect the development of craniofacial cartilage of its offspring. The present study investigates the effects of maternal E2 on larval craniofacial cartilage development by administering oral feed containing E2 (F-E2) to female zebrafish, and examines whether the swimming behavior and their stress coping style are influenced by maternal E2. The results showed that E2 contents responded to dosage and time in male fish after being fed with a diet containing E2. In addition, the E2 contents in female ovaries showed a significant increase after 250 mg of E2/kg treatment for 14 d. On the other hand, the fecundity rate of F-E2 group was lower around 2 folds than FC (female fed 0 mg of E2/kg) group. Craniofacial chondrogenesis on 72 hpf (hours of post fertilization) of F-E2 larvae were abnormalities, and a recovery to a normal developmental pattern was observed at the 96 hpf stage. The swimming speed was slower for F-E2 larvae compared to the FC larvae; and the F-E2 juvenile seems to be less responsive to cortisol (LRC) after cold stress. According to the results, we suggested that F-E2 larvae might have worse environmental adaptability than FC larvae.
