Lipid-correction models for δ13C values across small pelagic fishes (Clupeiformes) from the Atlantic Ocean (2020-2022): sample fish data

This dataset compiles the data used in the paper "Lipid-correction models for δ13C values across small pelagic fishes (Clupeiformes) from the Atlantic Ocean”. This study aimed at defining the maximum taxonomic level required to obtain the best corrected δ13C values in small pelagic fish of the order Clupeiformes. This dataset contains δ13C, δ15N and C:N ratio values before and after a chemical lipid extraction, for 149 individuals of six species from the eastern Atlantic Ocean (Sardina pilchadus, Engraulis encrasicolus, Etrumeus whiteheadi, Sardinella aurita, Sardinella maderensis and Sardinops sagax). These individuals were caught during scientific campaigns in France (EVHOE 2020 campaign), Senegal (OMEGA project, 2022) and South Africa (DFFE surveys in 2020 and 2021).
