Table 2:
Summary of the chronic lethal maximum for salinity test for larval San Pablo hatchery-born Sacramento splittail (P. macrolepidotus)
| Salinity (‰) | Time (h) | Survival (%) |
|---|---|---|
| Larval San Pablo splittail chronic lethal maximum for salinity | ||
| 0.4–18.0 | 0–216 | 100 |
| 20.0 | 240 | 89 ± 11 |
| 22.0 | 264 | 35 ± 27 |
| 24.0 | 288 | 1 ± 1 |
| 25.0 | 300 | 0 |
Salinity was increased from fresh water at a rate of 0.08‰ h−1 until all fish lost equilibrium. Salinity, test duration (in hours) and daily survival (expressed as a percentage ± SEM) are reported for every 24 h after the first loss of equilibrium was observed.
