Delta Bass Study

Seaching for a real fish story: UCD grad student tracks the deltas largemouth bass

FAIRFIELD Anna Stephenson is catching largemouth bass in the Sacramento-San Joaquin Delta, cutting a short incision on their underside, placing a black tracking device inside their peritoneal cavity and releasing them back to the water.

Then she and other researchers will know when the eight or so fish with electronic devices leave shallow water for deep water. They'll know how the fish move about during the year.

And maybe they'll discover clues to the plunge in the numbers of native fish such as the delta smelt, which largemouth bass eat.
