Abstract

The present study describes the ovarian development stages of the mud crab, Scylla paramamosain from Pak Phanang mangrove swamps, Thailand. Samples were taken from local fishermen between June 2006 and December 2007. Ovarian development was determined based on both morphological appearance and histological observation. Ovarian development was classified into five stages: proliferation (stage I), previtellogenesis (II), primary vitellogenesis (III), secondary vitellogenesis (IV) and tertiary vitellogenesis (V). The formation of vacuolated globules is the initiation of primary vitellogenesis and primary growth. The follicle cells were found around the periphery of the lobes, among the groups of oogonia and oocytes. The follicle cells were hardly visible at the secondary and tertiary vitellogenesis stages. Yolk granules occurred in the primary vitellogenesis stage and are first initiated in the inner part of the oocytes, then gradually concentrated to the periphery of the cytoplasm. The study revealed that the initiation of vitellogenesis could be identified by external observation of the ovary but could not indicate precisely.
