This work focused on determining the fatty acid (FA) composition of commonly discarded fish on the Spanish Mediterranean coast in winter and summer to assess their potential use as raw sources of very long-chain polyunsaturated fatty acids (VLCPUFAs). Total n-3 VLCPUFA content significantly varies depending on capture season, and values were higher in winter for Pomadasys incisus (1.36 g/100 g), Chelidonichthys lucerna (1.67 g...
