Water Quality Standard
Optimal Water Parameters & Tolerance Thresholds
| Water Parameter | Optimal Range | Critical Stress Limit | Field Management SOP |
|---|---|---|---|
| Water Depth | 1.5 – 2.0 meters | < 1.0 meter | Maintain deep column to accommodate surface, mid-water, and bottom niche feeding. |
| Water Secchi Transparency | 25 – 35 cm (Green Plankton) | < 15 cm or > 50 cm | Apply Single Super Phosphate (SSP) and fermented cow dung slurry to maintain natural phytoplankton. |

Standard CIBA Operating Procedures (SOP)
- Stock healthy stunted yearlings (> 100g) rather than small fry to achieve 1.5 kg table size in 8 months.
- Maintain the 4:3:3 polyculture ratio (Catla surface, Rohu column, Mrigal bottom) for balanced grazing.
- Apply Agricultural Lime @ 200 kg/acre annually to neutralize organic acidity on pond bottoms.
