A Colorado man has been fined $100,000 for stocking ponds at a Wyoming ranch 
with rusty crayfish, a destructive species that officials say could have 
significantly damaged aquatic habitat and native fish.
Shannon Skelton, 
34, the owner of Colorado Fisheries in Fort Collins, pleaded guilty to one count 
of unlawful transportation of illegally possessed wildlife from Colorado to the 
Wagonhound Ranch in Converse County. Jointly with his company, Skelton must pay 
$40,000 in fines and $60,000 in restitution to the Wyoming Game and Fish 
Department.
Already, more than $34,000 has been spent to eradicate the 
crayfish -- native to the Ohio River drainage -- from three ponds and a section 
of creek on the Wagonhound Ranch in Converse County.
Colorado Fisheries 
creates fish habitat and sells trophy fish to ranches and fishing lodges, 
according to Game and Fish. Al Condor, the agency's regional fishery supervisor, 
said Skelton was adding the crayfish, which provide forage for other species, 
gto grow more and bigger fish.h
The crayfish were discovered at 
Wagonhound during a site visit to evaluate a plan to move fish from one pond to 
another, Condor said. Until that point, rusty crayfish had not been found in 
Wyoming.
gWe were very lucky,h he said. gThey were in a fairly confined 
area.h
The ranch managers were unaware of the crayfish and, like Game and Fish, was 
an unknowing victim, he added.
After isolating the ponds and minimizing 
their size, Game and Fish employees used chemicals to kill anything living in 
the water.
gWe tried, basically, to eliminate anything that breathed with 
gills,h Condor said. gThere was no way to sort out the good crayfish, the bad 
crayfish, and the fish that remained in the ponds.h
According to U.S. 
District Court documents, Skelton was originally charged with three counts of 
transporting wildlife in violation of the Lacey Act, a federal law prohibiting 
trade in plant and animals that are illegally taken, possessed, transported or 
sold.
The charging document alleges that between 2002 and 2005, Skelton 
transported freshwater crayfish and freshwater shrimp from Colorado to the 
Wagonhound Ranch in Converse County and to the Fish On Ranch in Albany County, 
and transferred a variety of freshwater shrimp to the Masterson Ranch in Carbon 
County.
Wagonhound business manager Dustin Ewing deferred comment to Game 
and Fish. Representatives of the Fish On Ranch and the Masterson Ranch were 
unavailable for comment.
Condor said hefs as certain as he can be when 
dealing with biological systems that all crayfish were eradicated. The 
department will continue monitoring the sites, and may survey waters basinwide 
as well, he said.
gUnfortunately, if we find them in the North Platte, 
which I donft think we will, we just canft deal with that,h Condor said. gIt is 
really unfortunate that somebody with a new aquatic species has the ability to 
transform an entire aquatic ecosystem.h
Private landowners stocking ponds 
with fish is common in Wyoming, Condor said. Game and Fish requires a permit, 
which is free. The process ensures that illegal species and fish with disease 
arenft placed in water which could seep through drainages to other waterways 
downstream.
