Hundreds of fish flounder

CALIFORNIA officials are trying to solve a stinky mystery: A die-off has left hundreds of fish floating in a recently restored lagoon.

California State Parks Angeles District Superintendent Craig Sap said scientists believe the Malibu Lagoon die-off, which began last Wednesday, is likely caused by unusually warm water temperatures.

But other possibilities include elevated nutrient levels, dropping levels of dissolved oxygen or having too many fish in the lagoon. Officials are taking water samples and fish for testing.
