- •
The most frequent prey in mainland Portugal was the Gnathophausia zoea, followed by cephalopods and teleosts.
- •
In immature fish from the northernmost areas the proportion of FA was MUFA>PUFA>SFA.
- •
Fish from mainland Portugal stop maturation in pre-spawning stage and presented PUFA>MUFA>SFA.
- •
Samples from Madeira showed PUFA>SFA>MUFA, with a significant prevalence of PUFA important for reproduction.
- •
未15N supports the existence of ontogenic differences in diet.
