A quick look at the work of NOAA's National Sea Grant College Program.

In 2016, the National Sea Grant College Program celebrates 50 years of working for America's coastal communities. This is a look at some recent regional highlights.

Julia Noordyk, Wisconsin Sea Grant's Green Bay-based coastal storms outreach specialist, has been with the organizaiton two years. But she's just begun to get her feet wet,

Lake Michigan, the world’s fifth largest lake, has undergone many changes through the generations. Its current conditions are heavily influenced by the arrival of nonnative Dreissenid mussels known as zebra and quagga mussels. These filter feeders are altering the amount of phosphorus available for phytoplankton throughout the lake, which has an effect all the way up the food chain. Research aboard the Lake Express Ferry is taking the pulse of the lake and informing management decisions.

To look at it, the round goby doesn't seem like much. A small fish the approximate size of an average pickle, it seems like the sort of creature that'd be the dominated in the aquatic universe, not the dominator.

But like an ecological David in reverse, the voracious goby has used strength of numbers to wreak serious damage on the gentle Goliath that is the Great Lakes food web. Sometimes found in groups of several hundred or more, round gobies have made short work of the key food sources that sustain the young of a lengthy list of Great Lakes sport fish: bass, walleye, and yellow perch. Round gobies also dine on sport fish eggs when the opportunity arises. These species are fighting back, feeding heavily on gobies, but goby populations are usually too large to be affected.

Worse, in what some researchers have dubbed a "classic ecological surprise," the gobies haven't limited their invasive ways to the Great Lakes: Over the past decade, they've also migrated to Wisconsin's streams and rivers, where researchers are very concerned they could have a similar devastating effect on the ecosystem.

Beginning in 2007, using funding provided by University of Wisconsin Sea Grant, UW-Madison ecologist Jake Vander Zanden and UW graduate student Matt Kornis set out to discover just what kind of impact the gobies might be having. Using nets and a portable electro-fishing system, Kornis and a team of student researchers sampled and analyzed goby populations at 150 different stream locations along Wiscosins' Lake Michigan coast.

"When we discovered round goby in some small streams in Wisconsin, it made us start to ask the question, what kind of impacts are they going to have?" stated Vander Zanden, the project's principal investigator. "How many miles of stream in Wisconsin are going to be invaded, and is this something we need to be concerned about?"

Kornis and his team spent several months sampling from a variety of stream habitats—sandy, temperate and rocky—as well as areas where goby populations were either absent, low or prevalent. Of the 75 streams Kornis's team sampled, 26 contained gobies. In more than 80 percent of those sample sites, the goby population was deemed small, with the remaining 10 percent described as "superabundant."

The most surprising finding? At most of the sites, gobies have yet to devastate the ecosystem the way they have in the Great Lakes.

"Over the last three years, at most of our sites and streams, we haven't seen the population level declines in the native species we would have expected based on what we know from the Great Lakes," said Kornis.

That doesn't mean it couldn't eventually occur. Kornis and Vander Zanden remain focused on tracking the inevitable progress of the goby. They've identified and mapped 1300 kilometers of Wisconsin streams that are at risk for goby invasion, based on habitat suitability and natural migration projections from areas where the fish have already become established. Both researchers caution that if fishermen and boaters aren't cautious about preventing the spread of invasive species like the goby, the number of invaded streams in the Lake Michigan basin could expand dramatically.

"Streams are different enough from lakes in terms of the amount of habitat and type of food available that maybe round gobies can't reach the same densities as in the Great Lakes," said Kornis. "Nonetheless, goby populations are growing in most streams. Since 2007, we've observed at least a doubling of round goby abundance at 65 percent of our sites."

Vander Zanden agrees that further vigilance is critical to goby containment and habitat preservation. "This species is on the move, their inland spread is really rapid, and there is a lot of suitable habitat for them," he said. "We're worried about them making their way into inland lakes all around the state. We expect that they will have big impacts in these systems. Anglers and boaters need to be aware and not transport these fish into new waters."

An environmental food web is an intricate, organic and delicate thing. Eliminate a strand here or introduce a new one there, and the entire structure can collapse. That's why researchers have paid such close attention to the food webs in Lake Michigan, where the appearance of several aquatic invasive species has threatened to upset the natural balance.

Harvey Bootsma and John Janssen, Wisconsin Sea Grant-funded professors at UW--Milwaukee's School of Freshwater Sciences, have their sights on the waters close to shore.

"A lot of our work has focused on what role round gobies may be playing," Bootsma said. "Up until now, the near shore has been neglected. From what we're seeing, there are some unique things going on. We've had a lot of changes in the last five years."

He's referring to a massive influx of round gobies, one of several aquatic invasive species that have set up shop in Lake Michigan's waters. In the case of the goby, the impact seems tied to strength of numbers. In short—they're legion. And they eat copiously.

"When we dive to do our research, there are at least a hundred swimming around us, watching us work," said Bootsma. "Numerically, they're clearly dominant in the nearshore zone."

Bootsma and Janssen are performing their research in conjunction with similar research teams in Indiana and Illinois, to see if conditions in one state are being replicated in others.

Existing research suggests that one of the round goby's preferred entrees is the quagga mussel, which is not the first case of one aquatic invasive species noshing on another.

However, Bootsma and Jansen's research is revealing that round gobies don't actually feed on quagga mussels until they grow larger—between two to four inches long. By conducting a chemical analysis of stable isotopes and fatty acids found in the gobies' body tissue, they're able to determine what the gobies are really eating.

"The mussels are actually a side dish," said Bootsma. "Most gobies, and especially the younger ones, are actually subsisting on other types of food."

Those other types include oligochaetes and chironomids, tiny benthic organisms that live in the Cladophora algae that have come to clog the shallow shorelines of Lake Michigan.

The question then becomes whether the round gobies' trips to the invertebrates section of the Cladophora buffet are, in effect, swiping sustenance from other nearshore fish, including yellow perch and spot-tail shiner. It's also unclear whether other Lake Michigan species like trout and salmon may be able to use the plentiful gobies as a food source to replace offshore food web components that have been affected by other invaders.

"We know that lake trout and brown trout are eating lots of round gobies," says Janssen. "But we also know that more pelagic species, like Chinooks, cohos and steelhead are not."

After spending months analyzing data collected from hundreds of samples, Bootsma and Janssen (as well as the research teams in Indiana and Illinois) are ready to head back out onto Lake Michigan and begin examining other sites.

"We're interested in learning if the patterns around Milwaukee County are typical of the whole lake," explained Bootsma.

If they are, their work could help to determine how the carrying capacity of Lake Michigan may have changed, which would affect decisions related to fish stocking and nutrient management. Stay tuned.

This video, courtesy of the Illinois Natural History Survey, shows Asian carp, primarily silver carp on the Illinois River near Havana, Illinois. The fish jump in response to the noise of the motor or where the crew is shown on a boat with nets, the charge from the electrofishing boat.

Sped up 10 times, this video emphasizes that quagga mussels are active animals--much more active than washed up shells on a beach would suggest.

Quagga mussels and zebra mussels feed by filtering tiny plant and animal plankton out of the water and extracting the nutrients they need. Material they don't digest is wrapped in mucus and expelled. This "pseudofeces" is rich in nutrients like phosphorus.

Each tiny mussel filters a quart of water each day. That vigorous activity, abetted by circulating water, has effectively filtered the entire volume of water in Lake Michigan and other Great Lakes.

In the Great Lakes, invasive quagga and zebra mussels deposit their waste in the relatively narrow bottom areas near shore, where the mussels live. This has caused two profound changes to the lakes: It has dramatically cleared the water, and it has concentrated nutrients like phosphorus near shore. As a result, phosphorus concentrations have decreased off-shore and increased near shore, and sunlight penetrates deeper into the water.

Among the many consequences to the lake's food web are a major shift of energy sources (phytoplankton) away from open waters, where they would ultimately support trout, salmon, and whitefish, and an increase in nutrients like phosphorus available to algae growing near shore.
