Qualitative assessment of the diet of European eel larvae in the Sargasso Sea resolved by DNA barcoding
European eels (Anguilla anguilla) undertake spawning migrations of more than 5000 km from continental Europe and North Africa to frontal zones in the Sargasso Sea. Subsequently, the larval offspring are advected by large-scale eastward ocean currents towards continental waters. However, the Sargasso...
