Based on hystomorphological studies, three stages ot oocyte development the gonads of red kinq and deep blue crabs are determined and described. Oocytes of small growth,large cytoplasmatic and trophoplasmatic growths have been found in the pro-spawned gonads. There are oocytes of small and large cytoplasmatic growth as well as young oocytes of trophoplasmatic growth in the gonads after spawning. According to these data it has been concluded that oocytes of red king and deep blue crabs are developed during two years.
