Ova mm in diameter. "Spent" or post-spawning conditions. RESULTS Ovarian volume was low in September (Figure 1), and no yolky oocytes were present (Figure 2). Gonadal recrudescence was initiated in October and the ovaries were characterized by oocytes in Stages II and III. Ovarian development apparently started earlier at Bombay O 40. Feb. Sept Oct. Nov.
