Reproduction biology of female common carp (Cyprinus carpio) in southeast of the Caspian Sea (Miankale Fishing Station)

A.Ghelichi*1, R. Akrami1, Gh. Bandani2 and S. Jorjani1 1 Faculties, Islamic Azad University, Azadshahr Branch, I.R. Iran 2 M.Sc. in Fisheries, Dept. of Stock Assessment, Golestan Fisheries Research Center, Gorgan, I.R. Iran (Received: 18 October 2009, Accepted: 30 October 2010)

Abstract Determination of spawning period and peak time of it has a crucial role in stock management and restocking of fish species. In the present study, the ovarian development and spawning of common carp in south-east of Caspian Sea were examined through histological studies. At the beginning of the study, samples were obtained through seining that was performed through commercial fishery organizations (the Golestan province) from October to March. Later, samples obtained through fishing by research organizations. Samples were taken randomly from the beach seine nets. The samples were considered from different aspects: fecundity, oocyte diameter, biometry, identification of different maturation stages, and gonado-samatic indices (GSI). Hematoxilin-Eosin method was used for staining of oocytes. Identification of maturation stages was done based on six-stage key. In the mean, absolute fecundity was 143302.8. GSI elevated until early January and then decreased. GSI increased sharply again until May. In June, a sudden decrease in changes was seen. The results from gonadosamatic index and histological studies showed common carp gonad has a continuous spawning period in the Caspian Sea and the spawning occurred initially over at least 8 months.

Keywords: Common carp (Cyprinus carpio), Reproduction period, Gonadosamatic index, Fecundity, Southeast of Caspian Sea
