Pattern of hatching in artificial Salton Sea water of three salinities at 24 C, plotted as in Figure 2. Some larvae displayed irreversible axial deformities at hatching (kinked or bent notochords). When these are subtracted from the total number hatched, there appear to be slightly more morphologically normal larvae in SSW (natural and artificial) than in sea water—except, again, in 25 °/oo (Table 5). The survival of hatched larvae was extremely poor in SSW (Figure 5), and no larvae survived to complete yolk absorption in artificial SSW of 35 and 45 °/oo. In natural SSW, approximately 6% of the larvae were alive at yolk exhaustion, which is nearly identical to the value of 5% for larvae in SSW in the first experiment. In contrast, survival to complete yolk absorp- tion was over 90% in natural sea water and in artificial sea water of 25 "Zoo- Larval survival declined somewhat in artificial sea water of higher salini- ties (Figure 5), but was 60% at complete yolk absorption, even in 45 °/oo-.
