California’s only native sunfish, the Sacramento perch, survived catastrophic floods in the 1860s and was so abundant that it was a regular staple in San Francisco’s markets before invasive species decimated its population.
Sacramento perch will never replace trout, state biologists said. Instead, the focus is on preserving a native species, and as an added benefit, the fish could allow anglers another option as temperatures rise, limiting seasons forMax Fish, the department’s senior environmental scientist overseeing the efforts, said the hope is it can be introduced to fishing spots in more urban areas.
Sacramento perch’s resiliency allowed it to survive the catastrophic floods that wiped out much of Central California more than 160 years ago. Scientists hope that by introducing it to Southern California it will help strengthen the gene pool and build data for the captive breeding of Sacramento perch. Some hope the native fish can someday flourish as a food source much like tilapia, a highly adaptable warm-water species that is illegal to produce in California due to its potential to invade native ecosystems.
Last summer biologists released Sacramento perch larval in Lindo Lake after it was drained, dredged and restored to its natural state and outfitted with fish habitat structures. But someone since then dumped in a bucket of largemouth bass, which eat native sunfish eggs, Lucero said. Lucero, with other state biologists, stunned the perch with an electrical current so they would float to the surface belly up to be able to scoop them up. They eventually loaded 37 young fish into a bin in the bed of a pickup truck, and Lucero drove them eight hours to the lake in San Diego County.
