Daily ration and diet of the European sardine Sardina pilchardus (Walbaum, 1792) was investigated in the Gulf of Trieste (Northern Adriatic Sea). Sardine showed a diurnal feeding periodicity with a peak around sunset. Estimated daily ration was 3.739 g DW/1000gTWW. Microscopic examination of stomach content revealed a diet dominated by teleostean eggs and decapods larvae, followed by copepods. Also tintinnids of the species Tintinnopsis radix were numerically important.

Abstract
Daily ration and diet of the European sardine Sardina pilchardus (Walbaum, 1792) was investigated in the Gulf of Trieste (Northern Adriatic Sea). Sardine showed a diurnal feeding periodicity with a peak around sunset. Estimated daily ration was 3.739 g DW/1000gTWW. Microscopic examination of stomach content revealed a diet dominated by teleostean eggs and decapods larvae, followed by copepods. Also tintinnids of the species Tintinnopsis radix were numerically important.File in questo prodotto:
