Feeding habits of redfish (Sebastes spp.) and Greenland halibut (Reinhardtius hippoglossoides) in West Greenland waters
A total of 2708 redfish and 3030 Greenland halibut stomachs were collect on the shrimp fishing grounds off West Greenland in summer and autumn 1990–1991 and in winter and spring 1992. The stomach contents of small redfish (5–19 cm) and small Greenland halibut (< 14 cm) were dominated by planktoni...
