This study examines the diet of nine taxa from seven families of pre-settlement coral-reef fish larvae collected in the lagoon of New Caledonia, south-west Pacific. Chesson's index of electivity indicated that the major prey groups in the diets, i.e. small copepods, small unidentified crustaceans and eggs, were positively selected by all larvae, provided they were at least 150 m wide. This result emphasizes the role of larvae's behaviour on their feeding.
