Burbot Recent discoveries of burbot in the Green River at Flaming Gorge Reservoir in Utah have concerned wildlife biologists, who fear the burbot could decimate the sport fish population in what is recognized as one of the world's top brown trout fisheries, because it often feeds on the eggs of other fish in the lake like sockeye salmon.

Sockeye salmon in freshwater lakes. The majority of sockeye spawn in rivers near lakes and juveniles will spend one to two years in the lake before migrating to the ocean, although some populations will migrate to saltwater in their first year.

The eggs usually hatch within six to nine weeks and the fry typically rear in lakes before migrating to the ocean. Males partake in competitive and sneaking tactics, formation of hierarchies, and non-hierarchical groupings
