Maturity Stages | Particular of the Gonads |
---|---|
Stage I, Immature | Ovary was thin, short and glassy in appearance. The ovary and testes could not be distinguished by naked-eyes. The stage was observed in the fish size under the first maturation size. |
Stage II, Maturing | Ovary developing; ovary and testes can be distinguished by with the naked-eye. Ovaries are opaque and creamy yellow. |
Stage III, Mature | Ovaries increased in size compared to stage II. Ovaries are reddish yellow, extending about 2/3 body cavity length. |
Stage IV, Ripe/Oozing | Ovaries are yellow to amber colored filling the entire body cavity, extending the entire body cavity length |
Stage V, Spent | Ovaries are rather flaccid, reddish-yellow. |
