SPRINGFIELD, Ill. (AP) - State biologists are offering advice for restocking ponds and small lakes after winter fish kills.

Illinois Department of Natural Resources experts say occasional fish kills are natural when light cannot penetrate ice. That slows the growth of algae and plants which produce oxygen.

Officials say shallow ponds are more likely to have been affected. Deeper ponds have more oxygen to begin with and can sustain fish during winter months.

Ponds that have experienced past winter fish kills probably did so again this winter.

Small bluegill can often survive low oxygen levels, but a pond owner should assume no bass survived and restock as soon as possible.

The Natural Resources department can supply advice on restocking bass, sunfish, bluegill, catfish and minnows. County fisheries biologists can also help.
