2021: Is This the Year That Wild Delta Smelt Become Extinct?
California Water Blog
2020 was a bad year for delta smelt. No smelt were found in the standard fish sampling programs (fall midwater trawl, summer townet survey). Surveys designed specifically to catch smelt (Spring Kodiak Trawl, Enhanced Delta Smelt Monitoring Program) caught just two of them despite many long hours of sampling. The program to net adult delta smelt for captive brood stock caught just one smelt in over 151 tries. All signs point to the Delta smelt as disappearing from the wild this year, or, perhaps, 2022.
In case you had forgotten, the Delta smelt is an attractive, translucent little fish that eats plankton, has a one-year life cycle, and smells like cucumbers. It was listed as a threatened species in 1993 and has continued to decline since then. Former President Trump made it notorious when he called it a “certain little tiny fish” that was costing farmers millions of gallons of water (not true, of course).
