This paper reports the effect of feeding with food containing 17α-methyltestosterone (MT.) and 17β-estradiol (ES.) on the testis development and sex ratio of a marine prawn-Penaeus orientalis. Results show that MT. may accelerate the process of spermatogenous cell developing into spermatid and spermatozoon, but ES.shows little effect. Both MT. and ES.have no effects on the sex ratio of the prawn.
