Survival of larvae fed every two days on bacteria H6 alone was not significantly different (T-HSD, P > ) from that of larvae fed live algae, and was significantly higher (T-HSD, P < ) than that of starved larvae (Fig. 5). Larvae from cultures inoculated every two days with 5 ml of 1 /jm-filtered seawater (SW) also showed higher survival (T-HSD, P < ) than that of starved larvae. Larvae fed on FA or IA were significantly smaller than larvae fed on live axenic algae (G&H, P ) at the end of the experiment (Figs. 5, 6). Additions of single bacterial strains to cultures of larvae fed FA or IA did not improve larval growth compared to larvae fed FA or IA alone (G&H, P > ). In contrast, growth of larvae fed FA inoculated with 5 ml of 1 ^in-filtered sea- water was significantly enhanced (G&H, P < ) com- pared to that of larvae fed FA alone or starved larvae (Fig. 5). Similarly, additions every two days of 5 ml of 1 //m- filtered seawater or strain H6 alone to larval cultures sig- nificantly enhanced the growth of larvae (G&H, P< ) compared to that of starved larvae. The poor growth of larvae fed FA may have been due to the rupture of the freeze-killed algal cells. 60Co-irradia- tion did not affect the integri
