ANTIOCH, California, June 7 \u2013 A\u00a0gene-editing\u00a0tool\u00a0that has led to new cancer therapies and a rapid test for COVID-19 is now\u00a0helping\u00a0scientists\u00a0find\u00a0endangered\u00a0species of\u00a0salmon\u00a0in the San Francisco Bay.<\/p>\n

The CRISPR-based Sherlock\u00a0tool\u00a0can identify four types of Chinook\u00a0salmon, including Sacramento winter-run and Central Valley spring-run, which are both protected under the federal\u00a0Endangered\u00a0Species Act.<\/p>\n

\u201cThe Chinook are a great fit actually because all of the runs, more or less, look the same,\u201d said Andrea Schreier, an adjunct associate professor at the University of California Davis and coauthor of a study published last year in Molecular Ecology Resources that examined using this\u00a0genetic identification on the\u00a0endangered\u00a0Delta smelt.<\/p>\n

\u201cThey\u2019re visually very similar and the current method we have to identify the different types is based on what length they are at a particular age and it\u2019s not very accurate.\u201d<\/p>\n

Sherlock, which stands for Specific High-sensitivity Enzymatic Reporter Unlocking, identifies the fish using their genomic sequence. Researchers begin by taking swabs of mucus\u00a0from\u00a0the fish and combining with reagents that will glow if certain snippets of DNA are present. The battery-powered fluorescent reader gives results in 30 minutes, ideal for field research.<\/p>\n

By identifying the species, researchers believe they can better monitor population sizes and habitats.<\/p>\n

With extreme drought gripping California, some rivers are too warm for the\u00a0salmon\u00a0to survive, forcing the state to truck 17 million young fish to the San Francisco Bay\u00a0from\u00a0hatcheries.<\/p>\n

Emily Funk, an associate specialist who joined the team in July 2020, said the conservation angle drew her to the project.<\/p>\n

\u201cI think it\u2019s important to preserve our ecosystems,\u201d she said. \u201cI hope we can save the fish in our oceans.\u201d<\/p>\n

Melinda Baerwald, an environmental program manager with the California Department of Water Resources and coauthor of the study, plans to deploy the technology<\/a> at water pumping stations, which can impact\u00a0endangered\u00a0species.<\/p>\n

\u201cYou don\u2019t have to wait for weeks or in some cases months to find out the answer to if you\u2019re impacting an\u00a0endangered\u00a0or threatened species,\u201d she said, adding that they currently have to drive an hour and a half to a lab to confirm the identity of a species. \u201cInstead, you can find out at the moment that you\u2019re actually interacting with that species if you are affecting it.\u201d<\/p>\n
