gametogenesis%Argopecten irradians%Chlamys farreri
Histological characteristics of gametogenesis of two kinds of sca llops, gonochoric Chinese scallop, Chlamys farreri and hermaphroditic bay scallop, Argopecten irradians were investigated in this study. Spermatogenesis in C. Farreri h as different developmental stages: spermatogonia, primary spermatocyte, second spermatocyte, spermatid and spermatozoon. A large number of same developmental stage spermatic cells converg e at a definite area of the testis. Premeiotic, previtellogenic and vitellogenic oocytes ca n be found during oogenesis in C. Farreri, where oocyte distribution is obviously irregular. T he A. Irradians gonad consists of two different parts in one individual: one part functions as testis, the other as ovary. Between these two parts is a special appearance area, where a large number of spermatic cells are bound with two layers of acellular substance with many oocytes in it.
