Berried female holding tanks

The brood stock unit consists of various size (2 to 10 ton capacity) cement tanks/plastic pools/F.R.P tanks to hold the berried females collected from the brood stock ponds. These tanks are housed under an asbestos roofed shed. The berried females having different stages of egg development are stocked in separate tanks. Depending on the colour of eggs, the berried females are grouped into three categories.

• The prawns with orange colour eggs.
• The prawns with brown colour eggs.
• The prawns with grey colour eggs.
