High Ammonia Nitrogen-Induced Reproductive Toxicity in Goldfish (<i>Carassius auratus</i>) Mature Ovary

<div>Effects of ammonia stress on histopathology of ovary in goldfish (<i>C. auratus</i>) over 48 hr: (A–C) the control group; (D–F) high concentration group II, oocytes in the second phase; III, oocytes in the third phase; Ⅳ, oocytes in the fourth phase; YV, yolk follicle; YG, yolk granule; VA, vacuole; ZR, zona radiate; FM, follicular membrane; the red arrow indicates the rupture of radiation zone and follicular membrane, and the blue arrow indicates that the yolk particles begin to stick; red circle with x indicates yolk vacuolization.</div>
