Differentiation of the gonads and the appearance of cytochrome P-450 cholesterol side chain cleavage enzyme in gonads of the European eel, Anguilla anguilla L



Differentiation of the gonads and the appearance of cytochrome P-450 cholesterol side chain cleavage enzyme in gonads of the European eel, Anguilla anguilla L



Special Publication European Aquaculture Society ( 11): 143-156



Gonads first appeared at a body length of about 15 cm, when they consisted of a pear-shaped lamella connected together by a short fibrous stalk; no gonocytes were visible. At a body length of 22-26 cm, groups of 4-10 germ cells surrounded by connective tissue were visible. After about 6 months, the gonads contained secondary sex chords and had a testis-like histology; some germ cells had the appearance of oocytes.
