Carl Ostberg, Ph.D.
Carl is a Research Fish Biologist at the Western Fisheries Research Center.
Research Interests:
Carl’s research interests focus on evolutionary and conservation genetics. Current research projects include several studies directed at generating a greater understanding of intrinsic and extrinsic factors associated with hybridization between rainbow and cutthroat trout, using next generation sequencing to develop species-specific markers that differentiate endangered suckers endemic to the Klamath Lake basin, developing eDNA tool to evaluate recolonization extent of native and non-native fishes in the Elwha River following dam removal, and investigating morphological and genetic diversity of Dolly Varden in the Russian Far East.

Development and Refinement of Methods for Early Detection of European Green Crab
European green crabs are one of the most widespread marine invasive species on the planet. Where they are abundant, green crabs compete with other crabs and disturb sediment which can lead to loss of eelgrass and associated habitat essential for commercial, cultural, and ecologically important fish and invertebrate species. Green crab also are a major predator of clams, mussels, and oysters.
Cutthroat Trout (Oncorhynchus clarkii)
Species Studied - Cutthroat trout ( Oncorhynchus clarkii)
Bull Trout (Salvelinus confluentus)
Species Studied - Bull Trout ( Salvelinus confluentus)
