| Typical FCR range | 1.2–1.6 |
|---|---|
| Suitable water temperature | 26–32 °C |
| Minimum dissolved oxygen | 4 mg/L |
| pH range | 7.5–8.5 |
| Salinity | 10–35 ‰ |
| Typical harvest weight | 15–25 g |
| Production period | 3–4 months |
| Daily feeding rate | %3.0 |

In shrimp, monitoring appetite with feeding trays (check trays) prevents overfeeding and build-up on the pond bottom.
Worked example
Producing 200 t of Whiteleg Shrimp a year at an FCR of 1.40 requires about 280 t of feed. Lowering FCR to 1.30 saves about 20 t of feed.
