Lipid contents of Favia fragum larvae: changes during planulation period and effects of copper exposure

• Lipid contents of the planulae larvae of the brooding scleractinian coral Favia fragum were analysed throughout a monthly planulation period. Lipid levels exhibited a significant non-linear decrease during the planulation period, with a significant drop occurring between the 5th and 6th planulation day. The mean lipid content of F. fragum planulae released during the first 5 days of the planulation period was 47% by dry weight, compared to 34% during the final 4 days. Larval lipid content was also used to investigate the physiological response of F. fragum larvae to sub-lethal copper exposure (20 μg l-1) for 4 days. Copper exposure resulted in a faster rate of lipid consumption (6% day-1) compared to control treatments (1.3% day-1).
