MANAHAN percent recovery of dry organic weight as lipid and protein ranged from 65% (P. charcoti) to 89% (P. fuscus) — , 1 1 to 35% of total dry organic weight was not accounted for by the lipid and protein content of the eggs. Changes in biomass, lipid, and protein content during early development ofO. validus and A., hodgsoni Embryos of O. validus in the three replicate cultures had similar changes in biomass, lipid, and protein content from the egg (0 days) to early bipinnaria larva (35 days) (Fig. 3A). As stated earlier, one batch of eggs obtained from several females was used to start all three of the 200-1 cultures. Biomass increased significantly (ANOVA. VR = ***, [| = ) from the egg (0 days) to the early gastrula stage (pooled data for 9, 10, and 12 day-old) and thereafter remained fairly constant (, no significant difference between gastrula and early larval stage at d 35, VR = , Fomi32] = 4. 12). The equation for the fitted curve through all the biomass data points is given in the figure legend. Linear regression analyses were used to determine the rates of lipid and protein utilization during early development of O. validus (regression lines excluded for graphical simplicity. Fig. 3 A). Lipid and pro- tein content did not change significantly (determined by ANOVA) from the egg to early larva (VRpmtein = , VR,,pld = , n = 22). For the first 42 days of development of A. hodgsoni, lipid content did not change (Fig. 3B, VR = lns, n = 25). Both protein content and biomass did, however, decrease during this period. Protein decreased at a rate of ± ng individual-' day'1 (VR = **. FOM[tM] = ). Biomass decreased at a rate of ± ng individual"1 d"1 (VR = **, F005[l:2i] = ).
