Egg and larval amino acid composition as indicators of niche resource partitioning in pelagic fish species

We analysed the amino acid composition (AA) of eggs and larvae of the pelagic fish species Sardina pilchardus (sardine), Scomber scombrus (mackerel), Trachurus trachurus (horse mackerel) and Micromesistius poutasou (blue whiting) collected along the west Atlantic coast of Spain and from the Cantabri...

There was a significant relationship between larval AA similarity and larval spatial-temporal overlap among fish species, which means that those larval species that had greater spatial and temporal overlap, had a similar larval AA. On this basis, the differences in egg and larval AA within each fish species among different areas seem to be due to differences in habitat conditions; mainly temperature, salinity, and food quality and quantity.
