Diet composition of the Atlantic bluefin tuna (Thunnus thynnus L.) collected in 1998-1999 in the Icelandic Basin
This dataset presents the diet composition of tuna during autumn migrations to the Iceland Basin south of the continental shelf for the year 1998 and 1999 (area Va and XII defined by ICES). Each line in the dataset represents a different prey item found in the stomach of one tuna fish with a specifi...
