Dietas da abrótea (Phycis phycis) e do congro (Conger conger) dos Açores durante a primavera de 1996 e 1997
The forkbeard, Phycis phycis, and conger eel, Conger conger, are two coastal species, with a wide bathymetric and geographical distribution. The longline fleet of the Azores catches these two important commercial species. Few studies on their diet composition were found in literature. Data were collected during the demersal cruise surveys that took place aboard
the R/V “Arquipélago” during the spring of 1996 and 1997. Stomachs of 53 forkbeards and
95 conger eels were examined to define their diets. Both species fed primarily on fishes,
mainly on two benthopelagic species (Capros aper and Macroramphosus scolopax).
However, the relative importance of fish was higher for conger eel than for forkbeard,
which fed secondarily on decapods. Prey composition of the diet did not vary between
sexes, predator size or areas. However, some differences were found on diet composition
between depth strata. Prey composition indicates that both predators have the ability to feed near the bottom on benthic prey or in the water column on benthopelagic species
