Previously Undetected Parasite Discovered In Wild Wisconsin Trout

"*Anglers, Please Clean Your Gear*"

?

*MADISON, Wis.* ? The Wisconsin Department of Natural Resources (DNR) urges anglers to properly clean their gear after discovering the parasite "Myxobolus cerebralis"?in Elton Creek in Langlade County.?

Elton Creek is a Class 1 trout stream that recently tested positive for "Myxobolus cerebralis" below Elton Springpond and at Highway 64.

"Myxobolus cerebralis" is a microscopic parasite that damages the cartilage and nerve tissue of trout and salmon and has been known to cause whirling disease.

?It?s unknown how "Myxobolus cerebralis" will impact our local trout populations at this time,? said Justine Hasz, DNR Fisheries Management Bureau Director. ?In some states where the parasite has been found, trout and salmon have developed whirling disease, which has negatively impacted their local populations. However, other states with the parasite have seen no evidence of fish with whirling disease nor have they seen their trout and salmon populations impacted.?

Although no fish have been discovered in Wisconsin with clinical symptoms of the disease, the DNR is implementing a surveillance program to determine if any additional trout populations have been affected.

Anglers should watch for trout or salmon displaying any signs of whirling disease like blackened tails, skeletal deformities or swimming in circles, and report sightings to their local fisheries biologist [ [link removed] ]. These signs are not exclusive to whirling disease.

"Myxobolus cerebralis"?is only capable of infecting trout and salmon, with rainbow and brook trout thought to be the most susceptible. It cannot infect other fish species and poses no threat to humans or household pets like cats and dogs.

Though cooking harvested fish according to the U.S. Food and Drug Administration?s food safety guidelines [ [link removed] ] is always recommended, anglers are encouraged to never consume fish that appear sick or diseased.

*Help Minimize The Spread*

This parasite is nearly impossible to eradicate once it has been established, but steps can be taken to limit the spread. The DNR reminds anglers of the importance of cleaning and disinfecting their gear after fishing.

Anglers are encouraged to wear rubber-bottomed boots or waders. All water, aquatic vegetation, and/or mud that might contain the parasite should be removed from their fishing equipment streamside before being thoroughly cleaned. All fishing equipment, including boats, trailers, boots, waders, nets and float tubes should then be dried completely before being used again.

It?s also important to remember to not dispose of fish tissue or by-products into bodies of water to prevent the spread of aquatic invasive species [ [link removed] ] and other fish diseases [ [link removed] ].
