Asterisks indicate statistically significant differences versus the preceding phase in wild specimens and in captive-reared specimens distinctly,
† denote significant differences between wild and captive-reared individuals at the same phase of the reproductive cycle. Individual fatty acids are expressed as percentage of total fatty acids.
