This week in… Endangered Fish
The California Department of Fish and Wildlife (CDFW) has released results from the annual Fall Midwater Trawl (FMWT) Survey of the Sacramento-San Joaquin Delta. CDFW has conducted the monthly trawl survey between September and December since 1967 (except for 1974 and 1979). The Delta Smelt index was the lowest it has been since the trawl surveys were initiated nearly 50 years ago. Other pelagic fish species – including the striped bass, longfin smelt, threadfin shad, and American shad – were also near recorded lows.
Last week, the Supreme Court turned down appeals from Central Valley farmers and water districts to consider overturning pumping restrictions that had been put in place in 2008 to protect the Delta Smelt.
