Environmental DNA from invasive silver carp found in Michigan river

Environmental DNA from invasive silver carp found in Michigan river


Routine environmental DNA (eDNA) testing for invasive carp found a single positive sample in a Michigan river.

The U.S. Fish and Wildlife Service does annual testing for invasive bighead and silver carp. This year, they found a single positive sample in the St. Joseph River near the St. Joseph/Benton Harbor area.

Only one of the 220 water samples collected in June 2023 from stretches of the river between Lake Michigan and Berrien Springs showed evidence of genetic material from silver carp. That sample was taken near Marina Island.

“A positive eDNA sample does not necessarily indicate the presence of live fish,” said Seth Herbst, DNR Fisheries Research Program manager. “It is possible for genetic material to be introduced from other sources, such as boats or fishing equipment used in another state where invasive carp are present, then transported and used in Michigan waters.”

The sample was taken directly in front of a marina. Officials said this could mean boater traffic could have contributed to the detection.

“We use eDNA results as one piece of information to determine the best response to the potential threat of an invasive species,” said Herbst. “In this case, we have requested assistance from the U.S. Fish and Wildlife Service to conduct another round of eDNA sampling in the St. Joseph River beginning Sept. 5, with results to be processed as soon as possible.”

The USFWS has been conducting monthly electrofishing and netting in the St. Joseph River each summer since 2022 to capture and remove grass carp. They have not caught or spotted any silver carp.

Officials said there is no evidence of any live bighead, silver, or black carp in the Great Lakes or in Michigan Rivers. Anglers are encouraged to learn how to identify invasive bighead and silver carp and report any suspect fish.

“Along with our participation in the eDNA surveillance program, we continue to be diligent with early detection efforts, such as conducting fish population surveys, increasing awareness among anglers, and maintaining an invasive carp reporting website for anglers to share any suspicious catches or observations that occur during their outings,” said Herbst.

Michigan State football announces 2 new assistants for Jonathan Smith’s staff

Michigan State football announces 2 new assistants for Jonathan Smith’s staff


Michigan State football has two new assistant coaches, adding a defensive coach and quarterbacks coach under head coach Jonathan Smith.

The Spartans on Monday announced the hiring of James Adams from Wake Forest to work with their safeties. He will take over that position from secondary coach Blue Adams (no relation), who will assume former assistant Demetrice Martin’s role overseeing cornerbacks.

The school also confirmed Jon Boyer will is leaving Oregon State to coach MSU’s quarterbacks. Spartans offensive coordinator Brian Lindgren was responsible for the quarterbacks last season.

James Adams is a 16-year coaching veteran and Wake Forest alum who has been at his alma mater since 2022 under since-retired coach Dave Clawson. Adams began his career as a graduate assistant in 2009 with the Demon Deacons after winning two letters as a linebacker in 2005-06. He served as associate head coach and safeties coach with Wake Forest last season, and also has made stops at Purdue (2021), Navy (2020), Western Michigan (2019), Charlotte (2011-18) and Wofford (2010).

“James stood out during the interview process as someone who would be a great fit for our staff,” Smith said in a statement. “He has extensive experience coaching defensive backs and has been held in high regard on previous staffs with additional responsibilities as assistant and associate head coach.”

Martin, a former MSU star player and Los Angeles native, left his post as cornerbacks coach to take a similar role at UCLA, where he will be pass game coordinator and oversee the secondary. Martin worked under Blue Adams in his lone season returning to the Spartans after spending 14 seasons coaching on the West Coast.

Boyer moved to tight ends coach last season with the Beavers after Smith and the bulk of his staff left for MSU. Boyer spent the previous six seasons as the Beavers’ quality control coach and senior advisor on offense after serving as offensive coordinator at his alma mater Northern Colorado of the Football Championship Subdivision from 2012-17. Boyer was the Bears’ starting quarterback in 2000-01, then stayed there from 2002-05 and coached quarterbacks in 2004-05 before becoming offensive coordinator at Colorado Mesa from 2007-10.

“In having worked with Jon for several years at Oregon State, he has a thorough knowledge of our offensive scheme and what we’re trying to accomplish on that side of the ball,” Smith said in a statement. “He has strong relationships with our staff, and has done a great job throughout his career of developing and working with quarterbacks.”

As an understudy to Lindgren at Oregon State, Boyer worked with former Beavers quarterback DJ Uiagalelei as well as Aidan Chiles in 2023. Chiles returns in 2025 for his second season as the MSU starter.

That brings Smith’s coaching staff to 11 assistants, one more than the previous limit. The NCAA lifted those limitations in June, permitting any staff member to provide on-field coaching, but only 10 assistants and the head coach are permitted to actively recruit off campus.

Ex-Michigan running back fractures forearm in Rams’ regular-season finale


Sunday was supposed to be rookie Blake Corum’s chance to step into a featured role in the Los Angeles Rams backfield.

But the former Michigan running back didn’t get much of an opportunity, suffering a fractured forearm in the second quarter of a 30-25 loss to the Seattle Seahawks.

Rams head coach Sean McVay confirmed the injury after the game.

“He’s a tough, resilient guy,” McVay said. “He’s going to be a really good player for us for a long time, but he will miss the postseason.”

With the Rams having already clinched the NFC West crown entering Sunday, they rested No. 1 running back Kyren Williams, paving the way for Corum to handle a larger workload in the team’s regular-season finale.

Michigan’s all-time rushing touchdowns leader received just two carries for 10 yards and one catch for 12 yards before exiting. The 2024 third-round pick was on the sideline in the second half wearing a sling, finishing the year with 58 carries for 207 yards and seven receptions for 58 yards.

The Rams will host the loser of the Lions and Vikings’ Sunday night matchup in next week’s Wild Card round.
