Adults In the normal ovary of an adult shrimp, all prophase oocytes are located along the oviduct. When they are pushed ahead to form two lateral masses in the uterine cavity, the chromosomes are on the equatorial plate of the maturation division. After the second polar body is expelled in the central pouch of the uterus, embryonic development takes place in the uterine cavity as far as the gastrula stage (ovi- parous) or nauplius stage (viviparous) (Metalle and Ballardin, 1962). The effect of y-rays on the ovary of adult shrimps largely depends on the.
