The global catch of key wild whitefish is expected to climb next year, to 7.569 million metric tons -- a 4.32 percent rise and one of the highest levels for the group of species in years, according to data released by the International Groundfish Forum, which was held virtually this year.

The increased volume is expected to come largely from rises in the overall Alaska pollock and Atlantic cod catches, but several major species groups, including haddock, hake, saithe and redfish, are expected to see higher harvests.
