Abstract :

Abstract[1]Female gonadogenesis stage in perch, (perca fluviatilis Linnaeus, 1758) described based on 87 pieces caught by gillnet in Amirkelayeh wetland of Lahijan from December 2010 to November 2011. To perform this experience, ovaries were staged after dissecting, then fixed in formalin for histological process. Tissue samples were sectioned at 5-7 μm, before staining with Mayer’s Haematoxylin and Eosin. Variations of gonad maturation were divided to six stages; immature, previtellogenic, early vitellogenesis, late vitellogenesis, final oocyte maturation and spent stage. The studies showed a single ovulation and a short spawning period. Also a long vitellogenic stage (November-February) and existence of one active clutch which develop oogenesis in ovary confirmed total spawning in perch of Amirkelaye wetland.  * Corresponding Authors; Email: dianati3650@ yahoo.com
