SACRAMENTO, Calif. (AP) -- The latest trawl-net fish count shows the population of California's six species of Sacramento-San Joaquin Delta fish are dwindling.
A population crash started in 2002 for the six species, including the protected Delta smelt. A wet winter in 2011 halted the decline.
But the Sacramento Bee (http://bit.ly/ZAKaNV ) says the California Department of Fish and Wildlife count in fall 2012 shows those gains have been erased.
All six species returned to their prior low numbers. One species, threadfin shad, set a record low population in the latest survey.
The Delta fish population is considered an important barometer of estuary health.
