"With the new, exotic threats to our waters, such as whirling disease, quagga mussels, zebra snails and even plants, anglers need to learn a whole new way of dealing with their catch and equipment," he said.

Things to do to prevent the spread of whirling disease include:

1. Do not transport fish from one water to another and clean the fish in a different water. Also, if you're fishing a stream, don't move fish from one part of the stream to another area on the same stream.

2. After cleaning your fish, dispose of their parts, especially their heads, in a landfill.

3. If a landfill isn't available, clean the fish and dispose of their parts by burying them deep, a long way away from a water.

4. Clean all of your equipment thoroughly and dry it after every use.

"Fishing is a great sport, and it can supply an excellent meal," Schneidervin said. "We just need to develop a new way of thinking and dealing with some new, serious threats to (fishing)."
