Scales for stomach fullness and colour were developed and calibrated in order to provide an easy and reliable way to determine feeding intensity and food quality in sardines. The categories of the fullness scale reproduce the amount of food intake as indicated by the weight of the stomachs. The levels of the colour scale reflect the type of plankton eaten as shown by concentration of a-type phaeopigments and prey analysis of the stomach contents. Individuals of a wide length range were used in this study, leading us to suggest that these indices can be applied to the entire juvenile and adult sardine population. The use of the colour and fullness scales provides a rapid and efficient means of characterizing sardine feeding. Based on the colour and fullness categories of the stomachs the majority of stomachs were almost empty or at most half-full and the diet was composed of different proportions of phyto- and zooplankton items. As indicated by the prey analyses of the contents the most important constituent of the diet, in volume, were zooplankton prey.

Seriola Dumerili

Stomachs of 385 specimens of Seriola dumerili (Risso, 1810) have been analysed. Their coefficient of repletion is 50·8% in juveniles and 90·3% in adults. Juveniles feed almost exclusively on Teleostei with Engraulis encrasicholus and Sardina pilchardus as the main food; Cephalopoda (Loligo vulgaris and Sepiola sp.) and Crustacea (Squilla mantis) are also eaten. Adults feed on a great diversity of Teleostei headed by S. pilchardus and Merluccius merluccius.According to Smith-Vaniz (1986)Seriola dumerili is both epibenthic and pelagic, occurring at 18–72 m in small to moderate schools. Juveniles are associated with flotsam in oceanic or offshore neritic waters. Adults often live near reefs or at deep off-shore holes or drop-offs. It is found from the Mediterranean and the Bay of Biscay to South Africa, from Nova Scotia to Brazil, and also in the Arabian Gulf, Australia, Japan and the Hawaiian Islands.
