Table 4. Parameters of the model (equation 1) fitted to data used to describe the relationship between mortality of gelatinous zooplankton larvae and crude oil concentration at different exposure times (Fig. 2 and 3).
| Species | Stage | Exposure time (d) | LC50 ± ES | b ± ES | r2 |
| Aurelia aurita | Ephyra larva | 1 | *14.41±4.61 | *0.38±0.05 | 0.95 |
| 2 | *1.07±0.43 | *0.43±0.10 | 0.87 | ||
| 3 | 0.15±0.14 | 0.29±0.13 | 0.76 | ||
| Mnemiopsis leidyi | Cydippid larva | 3 | *14.52±0.99 | *6.70±1.15 | 0.95 |
| 4 | *12.48±1.45 | *6.95±3.58 | 0.97 | ||
| 5 | *11.69±0.71 | *4.22±1.17 | 0.99 | ||
| 6 | *8.94±0.76 | *2.46±0.53 | 0.99 |
Note that mortality of cydippid larvae was not observed the first 2 days of exposure. LC50: median lethal concentration (µL L−1), b: shape factor, r2 = correlation coefficient, SD: standard deviation, ES: error standard.
