Latest Asian carp eDNA sampling produces negative results


 

The Department of Natural Resources announced that the latest round of Asian carp environmental DNA (eDNA) sampling on the lower Kalamazoo River in Allegan County produced all negative results. Earlier this month, the DNR and U.S. Fish and Wildlife Service (USFWS) announced a single positive eDNA result for silver carp—a species of Asian carp—within the river, discovered during water sampling efforts conducted this summer.
Immediately after the DNR learned of the positive sample, the agency worked with USFWS to conduct this third eDNA surveillance effort. The two agencies collected 200 additional water samples on the lower Kalamazoo River Oct. 7 and 8. In addition to sampling, the DNR increased the presence of staff along the river to enlist anglers as part of surveillance efforts.
The previous positive result indicated the presence of genetic material of silver carp, such as scales, excrement or mucous. However, there is no evidence a population of silver carp is established in the Kalamazoo River. In addition to live fish, genetic material can enter water bodies via boats, fishing gear and the droppings of fish-eating birds.
“We greatly appreciate the quick work by USFWS to collect and evaluate these latest samples,” said DNR Fisheries Division Chief Jim Dexter. “We are pleased these samples were negative, but that doesn’t mean our efforts to keep Asian carp out of Michigan’s waters are over.”

The DNR will continue to take action in response to the previous positive result. Those actions will include:
• Conducting additional sampling efforts in the spring with USFWS to continue monitoring the river.
• Enhancing DNR fishery survey efforts, including expanding our outreach to anglers.
• Continuing public education efforts about all aquatic invasive species, including Asian carp, to increase general understanding of this significant threat to Michigan’s waterways.
Anglers and boaters are a first line of defense in the fight against aquatic invasive species. Anglers are urged to become familiar with the identification of Asian carp, including adults and juveniles, as the spread of juvenile Asian carp through the use of live bait buckets has been identified as a potential point of entry into Great Lakes waters.

Anglers and boaters are strongly encouraged to drain all water from their boats and to clean boats and gear after each trip. Invasive species and eDNA are known to “hitchhike” within live wells and attach to boat trails, anchors and fishing gear.

Silver carp eDNA detected in Lake Michigan tributary


This is a photo of a silver carp (a species of Asian carp) found in waters outside Michigan boundaries. Though no live silver carp has been found in Michigan waters, a recent positive environmental DNA (eDNA) result for silver carp was found within the lower Kalamazoo River in Allegan County, Michigan.

This is a photo of a silver carp (a species of Asian carp) found in waters outside Michigan boundaries. Though no live silver carp has been found in Michigan waters, a recent positive environmental DNA (eDNA) result for silver carp was found within the lower Kalamazoo River in Allegan County, Michigan.

The Michigan Department of Natural Resources (MDNR) and U.S. Fish and Wildlife Service (USFWS) are collaborating to assess a recent positive environmental DNA (eDNA) result for silver carp—a species of Asian carp—within the lower Kalamazoo River, Allegan County, Michigan.
Two hundred water samples were taken in July 2014, along the Kalamazoo, from below the Caulkins Dam in Allegan County, to the mouth of the river. Laboratory results, which take several months to process, were reviewed by the DNR Oct. 2. One of the of 200 samples tested positive for silver carp eDNA. The positive sample was taken from just below the Caulkins Dam.

An additional 200 eDNA samples were collected in the same vicinity in June and resulted in no positive results. The July sample represents the first time that Michigan has experienced a positive result for silver carp eDNA in Michigan’s Great Lakes waters outside of Maumee Bay.

The findings indicate the presence of genetic material of silver carp, such as scales, excrement or mucous. However, there is no evidence that a population of silver carp is established in the Kalamazoo River. In addition to live fish, genetic material can enter water bodies via boats, fishing gear and the droppings of fish-eating birds. The lower Kalamazoo River is popular for recreational activities including fishing and boating. Activities such as these may increase the possibility of eDNA entering the river without the presence of a live silver carp.

“Although not conclusive, this finding heightens our vigilance and sets into motion a specific response,” said MDNR Director Keith Creagh. “We will work with our partner organizations and anglers on next steps to protect the Great Lakes and its tributaries against this significant threat.”

In response to the finding, the MDNR:

Requested additional assistance last Friday from the USFWS to implement a third eDNA surveillance effort on the lower Kalamazoo River. The collection of an additional 200 samples begins Oct. 7. Analysis of the samples will be expedited and results should be available within a month.

Will increase the presence of MDNR staff along the Kalamazoo River to enlist anglers to report any Asian carp sightings.

Will place information in local bait shops to broaden public awareness.

“At the state’s request, the U.S. Fish and Wildlife Service is providing all the resources and technical expertise we have available,” said U.S. Fish and Wildlife Service Deputy Regional Director Charlie Wooley. “The Service is committed to working in a coordinated, landscape-level, approach to prevent the establishment of self-sustaining populations of Asian carp in the Great Lakes.”
Asian carp, including bighead and silver carp, pose a significant threat to the Great Lakes ecosystem, the $7 billion fishery, and other economic interests dependent on the Great Lakes and its tributaries. Silver and bighead carp are likely to compete with native and recreational fish species and are known to quickly reproduce.
“The Kalamazoo River results further point to the urgency of the Great Lakes states to be vigilant in seeking all solutions to keep Asian carp and other invasive species out of the Great Lakes basin,” said Creagh. “Michigan continues to advocate for hydrological separation between the Mississippi River basin and the Great Lakes basin as the best long-term solution to the threat of Asian carp. By working together as a united front, we can address the imminent threat invasive species pose to our quality of life.”
Anglers and boaters are vital stewards to prevent movement of Asian carp and other invasive species that threaten Michigan’s waters. Anglers are urged to become familiar with the identification of Asian carp, including both adults and juveniles, as the spread of juvenile Asian carp through the use of live bait buckets has been identified as a potential point of entry into Great Lakes waters. Anglers and boaters are strongly encouraged to drain all water from their boats and to clean boats and gear. Invasive species and eDNA are known to “hitchhike” within live-wells and attach to boat trailers, anchors and fishing gear.

Man sentenced for selling game fish


A Grand Rapids man that sold catfish he had caught in the Kalamazoo River has been sentenced to four months probation.

The man, Leon Terrill Smith, 40, had advertised the catfish on Craigslist as for sale. Michigan DNR law enforcement officers worked with the Wildlife Resources Protection Unit (WRPU) and made contact with Smith, who sold 14 catfish to WRPU members.

Officers arrested the man after the sale for selling sport caught fish, driving while license suspended and an outstanding arrest warrant. Investigating officers were advised Smith also had previous felony convictions for drug and firearms violations.

A person convicted of buying or selling game fish or any parts of game fish is guilty of a misdemeanor punishable by imprisonment for not more than 90 days or a fine of not less than $250.00 or more than $1,000.00, or both.

Smith appeared in court Tuesday, July 9, and entered a guilty plea. He was sentenced to four months probation and must take part in an educational series on fishing laws in Michigan.

Smith reportedly did not know it was illegal without a commercial license. DNR officials say that sport fishing is not health regulated and the fish could be contaminated.

The DNR reminds readers that you can call the Report All Poaching Hotline at 800-292-7800 to report any natural resources violations, including hunting and fishing violations.
