Seasonal Variations in Gonadosomatic Index, Hepatosomatic Index, and Condition Factor of Metapenaeus affinis

Egyptian Journal of Aquatic Biology and Fisheries
Samples of Metapenaeus affinis were collected from the Iraqi coastal waters between January 1 and December 1, 2021, to investigate the development of sexual maturity. Seasonal variations in gonadal function were observed in males, with peak rates (0.052) recorded in summer and the lowest rates (0.024) in winter.
