| 英文摘要 | In this study, we investigated seasonal variations in the concentrations of estradiol-17 beta (E-2) and testosterone (T) in the gonad of the cockle Fulvia mutica from March 2004 to February 2005 in relation to the reproductive cycle. Histological data showed that F. mutica is a hermaphrodite bivalve species. and gametogenesis took place during winter-spring (November-April) and spawning occurred in summer (May-June) when water temperature was higher. E-2 and T concentrations were measured enzyme-linked immunosorbent assay (ELISA). E-2 concentrations varied between 7.27 and 32.63 pg/g wet weight and T concentrations ranged from 22.83 to 77.15 pg/g wet weight throughout the year. Both steroids exhibited a similar annual pattern that correlated with the reproductive cycle. The two peaks of E-2 and T concentrations in November and May-June occurred at critical moments of the F mutica reproductive cycle: the onsets of gametogenesis and of the spawning period. E-2 and T concentrations were low during the non-reproductive period extending from July to October. These results suggest that E-2 and T Could play a role as endogenous modulators in the reproductive cycle of F mutica. |
