Figure 2.
Plot of the fish larva horizontal swimming velocity Uswim as function of time after spawning for the various swimming scenarios 4, 9–16 listed in table 1. Following equation (2.1), Umax is the maximum swimming cruise speed, Tpre-flexion is the pre-flexion time, Tmax is the time at which the post-flexion larvae reach maximum cruise speed and PLD (=Tmax + 4 days) is the pelagic larval duration. Scenario 13 was the same as scenario 4 except that the hearing distance W was reduced from 2000 to 1000 m. Scenarios 5–8 were the same as scenario 4 except for different values of the subgrid-scale horizontal turbulent diffusion coefficient Kx.
