| Abstract: | The embryonic wet weight, dry weight, yolk volume, energy content, and oxygen consumption of the southern pigfish Congiopodus leucopaecilus (Richardson, 1846) were followed from fertilisation to yolk sac absorption, at 11.5°c and salinity of 34.5%6. Measurements of yolk energy and catabolic energy changes did not show any evidence of an energy deficit before the onset of feeding capability. |
