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.

Field surveillance and sentinel exposures to detect Ceratonova shasta in Chinook Salmon from the Lake Washington watershed Field surveillance and sentinel exposures to detect Ceratonova shasta in Chinook Salmon from the Lake Washington watershed

Ceratomyxosis, characterized by enteritis, enteronecrosis,and abdominal distension, is caused by the myxozoan parasite Ceratonova shasta. Ceratonova shasta is capable of infecting a range of salmonids, including Chinook salmon, often resulting in increased morbidity and mortality in infected populations. Ceratonova shasta is endemic in the Pacific Northwest, however there is limited data...

The dataset supports studies performed in Washington state in 2022 and 2023 that investigated how detection of European green crab eDNA is affected by sampling season, green crab density, and the time at which samples are collected across a tide cycle. The data include sample site locations and descriptive categories, volume of water (L) filtered for eDNA analysis for each sampling event...

Environmental DNA survey dataset for fish and amphibians in mountain lakes of Olympic National Park Environmental DNA survey dataset for fish and amphibians in mountain lakes of Olympic National Park

In the western United States, there has been a long history of planting fish into historically fishless mountain lakes for the purpose of recreational fishing. This practice can have detrimental effects to lake ecosystems, particularly amphibian populations. We compiled records of fish plantings into lakes on the Olympic Peninsula in western Washington State dating back to 1930. Our...

These data were generated from a five-day laboratory study that compared environmental DNA (eDNA) concentrations derived from live and dead rainbow trout (Oncorhychus mykiss) to investigate how eDNA shedding differs between live and dead fish. Live and dead fish were each housed in separate tanks and eDNA samples were collected from each tank after 1, 2, 3, and 5 days. Additionally...

Global restoration and conservation of freshwater biodiversity are represented in practice by works such as the Klamath River Renewal Project (KRRP), the largest dam removal and river restoration in the United States, which has reconnected 640 river kilometers. With dam removals, many biological outcomes remain understudied due to a lack of pre-impact data and complex ecosystem recovery...
