Résumé

The feeding spectrum analysis of 1437 stomachs of large scale gurnard, Lepidotrigla cavillone, collected from summer 1977 to spring 1978 in four different regions of Greek seas suggested that it feed as an active predator just above the bottom, utilizing mainly nektonic or epibenthic invertebrates. The food habits of this species were rather similar in all studied regions throughout the year. Mysids constituted the most important food resource during all seasons either by weight, number or frequency of occurrence. Decapods were the second most important food group, while amphipods were the third most numerous. In winter, decapods decreased in importance, while mysids increased by weight. The feeing of large-scale gurnard exhibited only slight seasonal variation in the principal preys. The small variation of overlap values between seasons and between regions suggested no seasonal or regional variation in prey availability.
