Funding for invasive carp barrier falls short


With a historic $17 billion state budget surplus this year, environmental advocates hoped Minnesota lawmakers would make a big investment to stop the advance of invasive carp up the Mississippi River.

“It was an opportune moment to do some big things this year,” said Whitney Clark, executive director of the nonprofit Friends of the Mississippi River, a member of the Stop Carp Coalition.

The coalition urged lawmakers to approve about $17 million for prevention measures, including installing a bio-acoustic fish fence at Lock and Dam 5 near Winona. The system uses bubbles, sound and light to deter invasive carp from swimming upstream. It’s currently being tested on the Cumberland River in Kentucky.

Instead, Minnesota lawmakers included a fraction of that amount, $1.72 million, in the omnibus environmental budget bill to expand the Minnesota Department of Natural Resources’ invasive carp prevention and management efforts. Clark said they missed a key opportunity.

“I think people will be very, very shocked and disappointed if something that was preventable was allowed to happen because of inaction or decisiveness, at a moment when we still had an opportunity,” he said.

Advancing threat

Silver carp are one of four species collectively known as invasive carp, along with grass, black and bighead carp. They’ve been moving up the Mississippi River and other waterways since they were accidentally released into Arkansas waters in the 1970s.

Invasive carp are fast-growing and voracious eaters, outcompeting native fish for food and leading to a decline in biodiversity and water quality in rivers where they’re established.

Silver carp are known to jump out of the water, sometimes injuring boaters. That’s made for popular YouTube videos. But they also present a serious environmental challenge.

University of Minnesota Professor Peter Sorensen has been studying invasive carp for a decade, including their behavior, movements, impacts and how to stop them from moving upstream and reproducing.

“It’s not one adult silver carp that really is a big concern,” he said. “It’s when they have babies, and you’re looking at hundreds of thousands of young. Then you have a really serious problem.”

Individual invasive carp have been caught as far upstream as the Twin Cities metro. In 2020, 51 carp were captured just south of La Crosse, Wis., downstream from Winona.

This year on March 20, the day a Senate committee held a hearing on the barrier funding bill, the DNR announced commercial anglers had captured 30 silver carp near Winona, the largest single catch of invasive carp so far upstream.

Deterring with sound

Sorensen’s lab has been testing the bio-acoustic fish fence, or BAFF, with promising results.

Invasive carp have exceptionally sensitive hearing, especially to higher frequencies. The BAFF projects sound onto a stream of air bubbles, creating a wall of sound that invasive carp avoid.

Sorensen said Lock and Dam 5 is an ideal location to keep invasive carp out of the upper Mississippi, for several reasons. There are no side channels or bypasses around the dam, and its spillway gates are only open a fraction of the year. 

Also, there’s a relatively small pool of water above the lock and dam, trapping any invasive carp that get through.

Sorensen thinks a barrier should be one of several strategies to combat invasive carp at Lock and Dam 5, along with adjusting spillway gates and physically removing carp above and below the dam.

The BAFF system is not a silver bullet, he said, but could be a reasonable stop-gap measure that would last for the next couple of decades.

“If they do get through and they spawn, I know of no technology approach that can even come close to controlling hundreds of thousands of fish above that location,” Sorensen said.

Exploring options

Minnesota DNR officials say more work is needed to determine whether the bio-acoustic fish fence is the best solution. 

Before spending millions of dollars, the agency said it wants to evaluate all the available technologies and possible locations through a strategic decision-making process with help from the U.S. Geological Survey.

That process is currently underway and on track to wrap up by December, said Heidi Wolf, who heads the DNR’s ecosystem management and protection section. 

“It’s to get the right people in the room, including stakeholders and citizens of Minnesota, to say what are our values? What are we looking for here? What makes sense for Minnesota?” she said. 

Wolf said the BAFF’s engineering design was only about 10 percent complete. And there were lingering questions, including who would own and operate it and what it would cost to maintain.

There are other promising designs that could be less expensive, Wolf said, including an acoustic deterrent system that the U.S. Army Corps of Engineers is testing at Lock and Dam 19 on the Mississippi River in Keokuk, Iowa. 

The DNR is still formulating a plan for how to spend the $1.72 million appropriated by the Legislature, Wolf said. The bill designated $325,000 for the University of Minnesota to study changes in dam spillway gates that could help prevent invasive carp from getting through.

The DNR also might increase its commercial fishing efforts that target invasive carp, Wolf said, as well as tagging and tracking the fish to learn more about their movements.

And the agency wants to learn more about the potential impacts of a barrier on native fish traveling upstream.

‘Invest now or pay later’

Advocates worry that further delaying the installation of a barrier could put the river at risk. 

If invasive carp become established in Minnesota, they’ll have devastating impacts not only on the river’s ecosystem, but also the economy, tourism and recreation, said Colleen O’Connor Toberman is Friends of the Mississippi’s land use and planning director. 

“If a silver carp can jump 10 feet in the air and knock you out of your boat and give you a black eye, give you a concussion while you’re trying to go out fishing or hunting or waterskiing, that is a unique impairment, and people won’t go on the water,” she said.

Sorensen said he’s also concerned about a barrier’s impacts on native fish, but thinks they could be lessened by installing a fish elevator, which has been used in other rivers to carry migrating fish over a dam.

In some rivers where invasive carp have established themselves, the native fish population has plummeted by 50 percent, he said.

“So lack of action in itself will be disastrous to native fish on a permanent basis,” he said.

The DNR said there’s no evidence that invasive carp are reproducing in Minnesota waters yet.

But advocates say without a major investment to stop them, it’s only a matter of time before they’re here to stay.

“We either invest now, or we pay later,” O’Connor Toberman said. “There is no way to avoid the expense of invasive carp.”

As Climate Threats to Agriculture Mount, Could the Mississippi River Delta Be the Next California? – Inside Climate News

As Climate Threats to Agriculture Mount, Could the Mississippi River Delta Be the Next California? – Inside Climate News


This story was originally published by The Tennessee Lookout.

A smorgasbord of bright red tomatoes and vibrant vegetables line the walls of Michael Katrutsa’s produce shop in rural Camden, Tennessee. What began a decade ago as a roadside farm stand is now an air-conditioned outbuilding packed with crates of watermelon, cantaloupe and his locally renowned sweet corn — all picked fresh by a handful of local employees each morning.

The roughly 20-acre farm west of the Tennessee River sells about half of its produce through his shop, with the rest going to the wholesale market.

Farms like Katrutsa’s make up just a sliver of roughly 10.7 million acres of Tennessee farmland largely dominated by hay, soybeans, corn and cotton. Specialized machines help farmers harvest vast quantities of these commodity “row crops,” but Katrutsa said the startup cost was too steep for him. While specialty crops like produce are more labor-intensive, requiring near-constant attention from early July up until the first frost in October, Katrutsa said he takes pride in feeding his neighbors.

The World Wildlife Fund sees farms in the mid-Mississippi delta as ripe with opportunity to become a new mecca for commercial-scale American produce. California currently grows nearly three-quarters of the nation’s fruits and nuts and more than a third of its vegetables.

But as climate change compounds the threats of water scarcity, extreme weather and wildfires on California’s resources, WWF’s Markets Institute is exploring what it would take for farmers in West Tennessee, Mississippi and Arkansas to embrace — and equitably profit from — specialty crop production like strawberries, lettuce or walnuts. 

Specialty crops make up only 0.19% of the region’s farm acreage, but their higher sale value allows them to generate 1.08% of the region’s agriculture revenue, according to WWF’s May report, called The Next California, spearheaded by Markets Institute Senior Director Julia Kurnik. She argues that there’s an opportunity to proactively create more inclusive, higher-yield business models on existing farms, preventing natural ecosystems from being unnecessarily transformed into farmland.

But shifting produce growth to the Mid-Delta comes with hurdles: it requires buyers willing to try new markets, understanding of new crops’ diseases and needs, specialized equipment like cold storage and lots of expensive hands-on labor.

“It is not as simple as a farmer simply putting new crops in the ground,” Kurnik said.

Early Adopters Put Idea to the Test

Sixth-generation Arkansas farmer Hallie Shoffner is putting WWF’s models to the test through a nonprofit called the Delta Harvest Food Hub. The hub works with Black and women farmers to pilot the scalability of growing specialty crops in the Delta region, starting with specialty rice.

Shoffner grows basmati, jasmine, sushi rice, sake rice seeds and more on her 2,000-acre, century-old farm located in an unincorporated town outside Newport, Arkansas. She’s skeptical about a full switch to produce, but sees specialty rice products as “low-hanging fruit” easily adopted in the mid-Delta, where commodity rice is already widely grown.

The United States is the fifth-largest rice exporter in the world, and Arkansas is the country’s top producer, with other Mississippi River valley states not far behind. But the majority of specialty rice is grown in California or imported from East Asian countries.

“We are forward-thinking farmers who want to change, who want to do something different,” Shoffner said. “We want to make more money, because we know we cannot make as much money as small farms in the current agricultural economy.”

The commodity farming that dominates Delta agriculture makes the economic success of farmers largely dependent on the market prices of rice, corn, soybeans, wheat and other crops, Shoffner said. This incentivizes farms to grow larger to ensure they turn a profit even when prices are low, like they are now. But smaller farms struggle to stay afloat.

Shoffner said her vision for developing specialty crop markets in Arkansas will be through more collaboration between many smaller farms to diversify crop production and produce for large contracts together. She’s also exploring possibilities for expanding chickpea, sunflower, sesame and pea production in Arkansas.

And while she’s at it, Shoffner is working to make agriculture more equitable.

“As a white farmer who is a sixth generation farmer, I realize that I have inherited a large amount of land that systematically disenfranchised Black farmers,” Shoffner said. “And it is my responsibility to acknowledge that, and leverage what I’ve been given to help others.”

Her project, Delta Harvest, has a contract to grow specialty rice with a large company and she’s working with several Black farmers. She was too small to do it by herself, so they are doing it cooperatively.

Finding the Right Markets

In Mississippi, efforts to shift some of California’s sprawling specialty crop industry to the Mid-Delta drew skepticism from some farmers—even those with established specialty crop operations.

For the past 20 years, Don van de Werken has co-owned a 120-acre blueberry and tea farm in Poplarville, Mississippi, distributing much of its crops to buyers in his county and nearby cities.

Van de Werken questioned whether there would be enough regional demand to sustain a scaled-up specialty crop industry in Mississippi, noting that the success of his own enterprise hinges on targeting hyper-local markets like New Orleans. Shipping vegetables, fruits and other produce to buyers outside the Delta region would quickly become cost prohibitive for local farmers, van de Werken said.

“The problem we have, not just in Mississippi but the mid South in general, is we just don’t have the population base,” said van de Werken, who is also president of the Gulf South Blueberry Growers Association. “We don’t want our blueberries to go to Maine or Seattle. We want to focus our produce in a regional market.”

To make growing specialty crops worthwhile, Mississippi farmers would need to identify nearby buyers willing to purchase the new products on a consistent basis, van de Werken said. While selling goods directly to retail grocery chains like Kroger is often difficult, farmers could reduce financial risks by signing purchasing agreements with regional brokers like Louisiana-based Capitol City Produce.

“Anybody that puts anything in the ground is already taking a risk, but you want to minimize that risk,” he explained. “If you can prove to the brokers and the buyers that they can make money doing this, then the farming will come.”

The WWF report investigates ways to distribute risk across the supply chain to make selling to new markets easier on farmers, and works to connect buyers with Mid-Delta farmers.

AgLaunch, a Memphis-based nonprofit that guides farmers in innovation, estimates that adding specialty crops to the Mid-Delta region could spur $4.6 billion in added revenue and 33,000 jobs. But while commodity crop prices are readily available on the Chicago Board of Trade, the specialty crop market is generally not so transparent. Large, vertically integrated companies usually dictate contract terms, AgLaunch President and farmer Pete Nelson said.

AgLaunch helps build “smart contracts” that allow multiple farmers to produce on a contract, helping them secure higher quantity deals with proper compensation as a collective.

Purdue College of Agriculture professor Fred Whitford said the idea of farming cooperatives that help smaller farmers carve out space in a large-quantity market is more than 100 years old. Whitford compared commodity producers to retail giants like Walmart, which make money by selling in bulk. Small producers are more like Ace Hardware, he said.

“Maybe the smaller folks have an ability to make more off their land by going to a specialty crop,” he said.

New Challenges Need New Solutions

Farmers who embrace specialty crops will face hurdles before they make it to the market.

Growing produce can be more profitable but “easier said than done,” Whitford said. “It’s nice on paper … but boy, in reality, you’re going to have to keep an eye on this crop, whatever you’re growing, because one slip up … then you have lost a lot of money.”

In Tennessee, Katrutsa grew strawberries in addition to his other crops for 10 years, but last April, a hail storm pulverized his entire field, leaving him with nothing. He’s not growing strawberries this year, and he might not plant them again — he’s not sure if he can find enough labor to make it work.

He grows many types of produce so if one fails, it’s less catastrophic. He sources seedlings from a neighboring state (it’s cheaper than growing from seed) and plants five times each season to maximize yield.

He works with a consultant to help identify diseases and how to treat them. Tomatoes are the most challenging, Katrutsa said. Some of his tomato plants withered this year due to bacterial wilt that flourishes in wet soil and high temperatures and has few effective chemical remedies.

Chemical treatments pose other challenges. In Shaw, Mississippi, Michael Muzzi relies on a range of herbicides to grow soybeans and other feed grains on his 2,000-acre farm. Once sprayed, herbicides like Liberty and Dicamba remain in the ground and can drift in the air, which is hazardous to specialty crops, like tomatoes, that aren’t resistant.

“You’re not going to be able to spray [those herbicides] on specialty crops,” Muzzi said.  “You’d have to have something that’s chemically tolerant.”

Growing fruits and vegetables on a farm with previous heavy herbicide use would require insulating those crops from chemical runoff — a feat that could only be reliably achieved by leaving whole acres of land unused for years, he said.

AgLaunch is exploring innovative ways to address these problems. For some farmers, this means helping make their existing row crops more efficient using farmer-incubated technology, adding local value by growing specialty crops or taking on processing, Nelson said. 

Then there’s disruption with higher risk: farmers can partner with agriculture automation technology startups, allowing them to field test their products and collect data in exchange for farmer equity in the startup companies. If the startup succeeds, the farmer shares in the benefits.

“It’s not as simple as, ‘Hey, we should grow tomatoes,’” Nelson said. “It’s how you think about the whole value chain and make sure the farmer is protected. Make sure it’s not an opportunity just to grow a crop, but it’s an opportunity to own part of the processing or to build new products.”

Kurnik said WWF isn’t trying to recruit farmers to start growing specialty crops – they just want Mid-Delta farmers to have the information they need to make informed decisions. In terms of acreage, row crops “dwarf” specialty crops in the United States. A small percentage shift would mean a significant change in the level of specialty crops in the Delta.

“We don’t need everyone to want to jump on board tomorrow,” she said. “They would flood the market if they did.”
