Linear regression between larval density (x: 50, 150 or 300 larvae mL−1) and larval performance in experimental flow-through and recirculation raising system.
| Performance parameter | Flow-through system | Recirculation system | ||||
|---|---|---|---|---|---|---|
| n | Linear regression | r2 | n | Linear regression | r2 | |
| Growth rate | 12 | 15.6 − 0.022x | 0.79 | 12 | 12.81 − 0.011x | 0.694 |
| Survival rate | 12 | 1.451 − 0.0038x | 0.48 | 12 | Not linear | |
| Food efficiency | 10 | 1853 – 3.356x | 0.496 | 11 | 1483 + 1.17x | 0.68 |
| Metamorphosis rate | 6 | 55.82 − 0.166x | 0.86 | 6 | 26.45 − 0.027x | 0.76 |
