After day 8, larvae fed the mixture of all eight algal species or TL
continued to grow, the fewer survivors (0.4% and 0.2%, respectively)
at the end of the experiment (day 26) reaching mean shell lengths of
374.0±22.9 μm(pediveligers) and 329.7±6.5 μm(late-umbo larvae),
respectively. Larval cultures collapsed (sudden, high mortality) by day
16 when fed CC and by day 20 when given PL. Larvae fed DT, TS, PT,
and TP maintained slower growth rates after day 8, but nearly all had
died by day 20. Larvae fed CM showed faster growth after day 8 and
caught up in size with those fed TL by day 20
