Blog: ‘North Delta Arc’ Lifts Hope for Recovery of Native Fish
From the California WaterBlog in a post by the UC Davis Center for Watershed Sciences:
“Matt Young and Denise De Carion thought they had seen about all there is of fish communities in the Sacramento-San Joaquin Delta. … In all their dozens of sampling runs, the story was the same: the Delta supports predominantly non-native species such as bass, catfish and bluegill sunfish – the garden variety found in almost any North American warm-water lake.
“Then, in 2011, the story changed. Young and De Carion were helping the California Department of Water Resources explore fish populations in the north Delta, a region they had never surveyed and that no one had comprehensively sampled. … Rather than the typical catch of mostly non-native warm-water fishes, they netted a mix of natives and non-natives – predominantly river and estuary species such as tule perch and Sacramento splittail. …
“The realization inspired researchers at the UC Davis Center for Watershed Sciences to investigate what now appears to be an arc of habitat that supports native fish.”
