Fibrous and Cystic Lesions in the Ovaries of Aged Atlantic Cod ( Gadus morhua ): a Preliminary Report
Ovarian stromal fibrosis occurred in four Atlantic cod (Gadus morhua L.) from the northeastern Gulf of St. Lawrence (49°07′N, 59°18′W) and off Fox Harbour, Labrador (52°18′N, 55°52′W), with accompanying cystic lesions in two specimens.Externally the ovaries varied. Specimen 1 (115 cm fork length, ag...
