Abstract Anguilla anguilla elvers, reared in warm fresh water, were treated with 17 a‐methyltestosterone (MT) and with 17 α‐ethynilestradiol (EE), administered with a commercial diet. A very low proportion of untreated elvers developed as females. A very high proportion of the EE treated elvers deve...

Summary: | Abstract Anguilla anguilla elvers, reared in warm fresh water, were treated with 17 a‐methyltestosterone (MT) and with 17 α‐ethynilestradiol (EE), administered with a commercial diet. A very low proportion of untreated elvers developed as females. A very high proportion of the EE treated elvers developed as females and the gonads differentiated as ovaries at an earlier growth stage. Among the MT treated elvers, in a very low proportion of eels the gonads developed as ovaries, most into a undifferentiated testis‐like gonad and some with abnormal histological features. |
