[ES] Se han analizado 1526 contenidos estomacales de merluza de tallas comprendidas entre los 8 y los 65 cm de longitud total, procedentes de muestreos mensuales realizados en 1993 en el golfo de León. Los principales factores que influyen en el grado de repleción estomacal han resultado ser la talla de la merluza y la estación del año en que se ha capturado. La dieta está compuesta principalniente por peces y crustáceos aunque se aprecian diferencias en la composición relacionadas con la talla. Las merluzas más jóvenes se alimentan básicamente de pequeños crustáceos (eufausiáceos y misidáceos) y pequeños peces bentónicos (góbidos). A medida que la merluza crece, la irnportancia de los peces en la dieta aumenta. Los ejemplares grandes ≥25 cm TL se alimentan más frecuentemente de grandes decápodos y casi exclusivamente de peces nadadores activos como la sardina
[EN] A total of 1526 hake stomach contents from specimens ranging between 8 and 65 cm in total length were studied in monthly samples taken in the Gulf of Lions in 1993. Key factors influencing the degree of stomach fullness were related to the size and season. The hake diet is comprised primarily of fish and crustaceans but there were size-related changes in the trophic spectrum. The youngest hake feed mainly on small crustaceans (such as euphausids and mysids) and small benthic fishes (such as gobids). As the hake grows, the importance of fish in the diet increases. The larger specimens ≥25 cm TL feed increasingly on the larger decapods and, almost exclusively on active natatory fishes, such as the sardine
