individuals of 37C group did not contain any oocytes and gonial
germ cells (Fig. 3B). After transfer to normal temperature for five
months, all fish in the control group had normal ovaries with
mature stage oocytes. In the 37C group, all fish had thread-like
paired ovaries with the ovarian cavity, but without oocytes and
gonial germ cells (Fig. 3C). Some clusters of granulosa cells like
structure were seen in the ovaries.
