Macroscopic and microscopic studies of reproductive cycle of Capoeta capoeta intermedia in Shapour River, Bushehr province

This study was done to investigate the macroscopic and microscopic structure of the ovary of Siah mahi,Capoeta capoeta intermedia during sexual maturation cycle from November 2012 and October 2013. For this purpose, 330 C.c.intermediawere captured from Shapour River (Bushehr province) and transferred to the laboratory. After biometry, gonads were removed and weighted. Gonad samples fixed in 10% formalin and after providing tissue sections, stained with H&E and studied by light microscopy. The weight of female and male calculated 93.4 ± 38 g and 87.24± 25.5, respectively. Results showed that average total length females and males is 19.83±2.32 and 19.85±2 g cm, respectively. Overall female-male (F-M) sex ratio was 1:1.66 that was significantly differences between the sexes (P
