Condition and Feeding of Greenland Halibut (Reinhardtius hippoglossoides) in Flemish Cap and Other Areas: 1992-2003.

The seasonal, annual and geographical changes in the Relative Condition Factor of a total of 65,113 individual biological data of Greenland halibut (Reinhardtius hippoglossoides) were analysed. These data were collected in three areas of the North Atlantic (NAFO Div. 3LNO and 3M, and ICES Div. IIb)...
