Cytological comparison of gametogenesis of scallops,Argopecten irradians andChlamys farreri
摘要
Abstract
Histological characteristics of gametogenesis of two kinds of scallops
gonochoric Chinese scallop
Chlamys farreri and hermaphroditic bay scallop
Argopecten irradians were investigated in this study. Spermatogenesis inC. farreri has different developmental stages: spermatogonia
primary spermatocyte
second spermatocyte
spermatid and spermatozoon. A large number of same developmental stage spermatic cells converge at a definite area of the testis. Premeiotic
previtellogenic and vitellogenic oocytes can be found during oogenesis inC. farreri
where oocyte distribution is obviously irregular. TheA. 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.
