Dirk Encourages Anglers to Sink Teeth into Asian Carp Problem

Dirk grills Asian carp burgers.

Dirk Fucik has no illusions that he can turn back the Asian carp invasion that threatens the Great Lakes. But by making, selling, and even offering free samples of “carp burgers,” his Dirk’s Fish & Gourmet Shop in Chicago has been encouraging fellow anglers and others to slow the spread of these exotic species one bite at a time.

“We have been promoting the eating of Asian carp for about five years now,” said Fucik, a longtime member of B.A.S.S.

“We give out free samples every week at the shop, have worked with Illinois Department of Natural Resources, and Army Corp of Engineers to give away carp burgers at the Taste of Chicago, and we are partnered with the Shedd Aquarium in promoting the use of Asian carp.

“It’s a great-eating fish,” he added. “We just have to get past the bones and the stigma of carp.”

At Taste of Chicago, an annual food festival, Fucik typically gives away 800 burgers in two hours, with 90 percent of those who try them approving.

“When Americans think of carp, they think of German carp,” he said. “And that fish is a bottom feeder. It is a dark-fleshed meat, and it’s strong in flavor and bony.”

By contrast, Asian carp are plankton eaters, and their meat is white, resembling cod. But they are bony. To solve that problem, Fucik extracted the large bones and then ran the meat and small bones through a meat grinder.

“It’s similar to burger meat,” he said.

And at about $6 a pound, it’s much cheaper than salmon burgers at $18.

“We should all embrace the use of Asian carp for food purposes,” he said. “It is a great lean, low-fat protein and, being a problem invasive species, eating it is a great solution.”

Dirk's  Carp Burgers:

2 pounds Asian carp fillets, ground
1/2 cup Panko bread crumbs( this is optional)
2 tablespoons fresh garlic, chopped
2 tablespoons olive oil
1 tablespoon lemon zest
4 teaspoons dry oregano or 2 teaspoons fresh oregano
4 teaspoons black pepper
1 1/2 teaspoons kosher salt
1/2 teaspoon nutmeg

Combine all ingredients except panko crumbs. Grind the fish twice to make sure there are no more bones and to blend the spices. Add panko crumbs and form into patties or choose not to use breading. The burgers will be a little softer but just handle with care.

If you want to add cheese, use a soft cheese. Form a small ball of cheese and insert into the center of the burger. Form the burger around the cheese.

Cook for about 5 minutes per side on a hot grill, the cheese will start leaking out when they are almost done.

Florida's New Regulations Help Combat Lionfish Invasion

Florida is known as a tourist-friendly state, but starting Aug. 1, one visitor will no longer be welcome: the invasive lionfish.

Introduced into Florida waters in the late 1980s, lionfish populations have boomed in recent years, negatively impacting native wildlife and habitat.

Go here to learn about the threat that they pose to native fish species.

Several management changes go into effect Aug. 1 that will help the Florida Fish and Wildlife Conservation Commission (FWC) combat the growing problem by making it easier for lionfish hunters to remove the spiny predators and limiting further introduction of the species into the waters.

Changes include:

  • Prohibiting the importation of live lionfish;
  • Allowing lionfish to be removed via spearfishing when diving with a rebreather, a device that recycles air and allows divers to remain in the water for longer periods of time (currently, you cannot spear any fish when using a rebreather); and
  • Allowing participants of approved tournaments and other organized events to spear lionfish or other invasive species in areas where spearfishing is not currently allowed (such as certain state parks or refuges). This will be done through a permitting system.

See or catch a lionfish? Report a sighting by downloading the new Report Florida Lionfish app on a smart device or by visiting MyFWC.com/Fishing and clicking on “Recreational Regulations” (under “Saltwater”) and then “Lionfish.”

To learn more about lionfish, visit MyFWC.com/Fishing and click on “Saltwater,” “Recreational Regulations” and “Lionfish.”

Loss of Access Threatens Future of Fishing

Anglers are losing access to their favorite fisheries.

Sometimes, it’s because of development or budget cuts. Other times it’s because government bodies or even private groups have shut down public launch areas.

The latter is happening with increasing frequency because of a fear that invasive species such as zebra mussels and Eurasian watermilfoil will be accidentally introduced via contaminated boats and trailers. Sometimes the concern is legitimate. Other times, it’s simply an excuse to keep out the public.

This threat has grown so severe that one in five anglers surveyed by AnglerSurvey.com reported having to cancel or quit fishing a particular location in 2011 because they lost access to it. Most were able to shift their fishing to another location, but a third of affected anglers said that the loss caused them to quite fishing altogether.

“While access issues can often be overcome by fishing somewhere else, we are still losing some anglers each year due to problems with fishing access,” says Rob Southwick, president of Southwick Associates, which conducts the surveys at AnglerSurvey.com.

“When we add up the anglers lost year after year, whether as a result of marine fishery closures or dilapidated boat ramps, access remains a major long-term problem for sportfishing and fisheries conservation.”

You can help slow down this loss of access and possibly even reverse the trend.

First, be a responsible angler by making certain that you do not allow invasive species to hitchhike on your boat and/or trailer, and encourage others to do the same. When fishermen set good examples, those in power have less reason to try to deny access. Additionally, if you belong to a fishing club, encourage it to work cooperatively with lake associations and government bodies on plans to keep out invasive species.

Also, familiarize yourself with access issues, both locally and nationally. Attend public meetings when access issues are on the agenda. Write letters, send e-mails, and make phone calls to officials, emphasizing that quality access is important.

Solution: Make sure you leave every area better than you found it, be committed and vocal about preventing the spread of invasive species, and get involved locally so that angler interests are represented when decisions on access are made.

Snakehead Numbers Decline

Maryland DNR photo Good news from the snakehead front, as the Maryland Department of Natural Resources (DNR) announced that catch and distribution of the exotic predator in the Potomac River was lower in 2013 than in 2012.

In announcing the finding from the Tidal Bass Survey, biologist Joe Love said, “The 2013 observations represent the first decrease in catch and distribution since the species was first discovered in the Potomac River (2004). It is not clear whether the cause of the decline is increased angling effort or other factors.”

But angling effort has increased considerably in recent years, aided by initiatives from both DNR and the U.S. Fish and Wildlife Service.

Additionally, the state is providing more incentive for catch and harvest of snakeheads by instituting a state record program and including an invasive species category for awards in the Maryland Fishing Challenge.

Not all the news regarding snakeheads is good, however, as two adults were captured by electrofishing for the first time ever in the Wicomico River. Anglers had reported catching them there as early as 2011.

“It appears that it takes two years between angling reporting and collection by Maryland DNR’s Tidal Bass Surveys,” Love said.

Additionally, adult snakeheads were collected from the Patuxent, in numbers similar to 2012.

“Based on suitable habitat for northern snakehead and the population estimate, we calculated that there were about five per acre of suitable habitat,” the biologist explained. “Reports for Little Hunting Creek and Anacostia River ranged from four to nine northern snakehead per acre.”

The invasive fish also was collected “in relatively small numbers” from the Rappahannock, Rohde, Blackwater, and Nanticoke Rivers.

A small snakehead was captured in a trap from a ditched area that connects the Blackwater to the Little Choptank. This suggests that the fish could use this pathway to also colonize the latter, the biologist said.

How About Hippos?

If you think that we’ve made a mess of our lands and waters through intentional and unintentional import of exotic plants and animals, you are correct. For example, we now spend billions of dollars annually to control and mitigate the damage done by just four recently introduced species: bighead carp, silver carp, quagga mussel, and zebra mussel.

And in attempts to minimize problems, the government often has made them worse. During the 1940s, the state of Louisiana touted the South American nutria as a way to control water hyacinth, a fast-growing exotic that was crowding out native vegetation in wetlands. Today, the nutria is eating away those same wetlands, contributing to saltwater intrusion and coastal erosion.

In the early 1960s, the states of Alabama and Arkansas allowed import of grass carp to control aquatic vegetation in aquaculture ponds. By 1970, escapees had established populations in the Missouri and Mississippi Rivers. Today, these troublesome grazers are established in at least nine states and have been sighted in more than 40. Ask just about any bass angler, and he will tell you that the grass carp is public enemy No. 1.

And speaking of carp, we have the federal government to thank for one of the worst management decisions ever in regard to our fisheries. In 1877, the U.S. Commission of Fish and Fisheries began intensively cultivating and stocking common carp. In fairness, it was prompted to do so both by public pressure and by overharvest of native fish stocks. By the turn of the century, however, it already was regarded as a nuisance.

“Moreover, their rapid spread appeared to threaten both water quality and native species, as commissioners nationwide noted a deterioration of formerly clear and fertile lakes and waterways upon the arrival of carp,” says the National Park Service.

But you don’t know the half of it. Actually, things could be worse. Much worse. Instead of nutria eating away those Louisiana wetlands, we could have hippos. And who’s to say that these massive “water horses” which can weigh up to 4 tons and eat up to 100 pounds of vegetation a day, wouldn’t have spread east, west, and north?

They are “relatively tolerant of cold conditions,” says the Glen Oak Zoo, which also points out that “many individuals live to 40 years.”

Oh yeah, they also are generally believed to have killed more people in their native Africa than another animal, including lions and crocodiles.

All things considered, I’ll take the nutria, thank you. It tops out at about 12 pounds and is not as likely to charge me at the launch ramp.

But in 1910, Frederick Russell Burnham, a famed American scout and world adventurer, proposed replacing our nation’s depleted wildlife population --- we had hunted deer, turkey, and buffalo nearly to extinction --- with animals that he had encountered in southern Africa.

His proposal lined up nicely with the search for a solution to the growing problem of water hyacinths in Louisiana waters, as well as America’s need for more meat. Writing about this little known piece of American history, Jon Mooallem in American Hippopotamus, says that Rep. of Robert Foligny of New Iberia “liked to plug up problems with big solutions.”

Thus, Foligny introduced H.R. 23261, also known as the “Hippo Bill,” to “appropriate $250,000 for the importation of useful new animals into the United States.” The Washington Post assured readers that they would see shipments of hippos within a few years.

Fortunately for all us, a boatload of hippos never docked in New Orleans. But it wasn’t because of the unexpected discovery of good judgment in Congress. Rather, one representative said that the beasts should not be introduced because unscrupulous hunters would sneak onto the farms and hunt them for trophies.

Yeah, that’s the reason not to import aggressive animals that boast 20-inch teeth and can run at speeds of more than 20 miles per hour.

What turned the tide, though, was that the Department of Agriculture decided to transform swamps and other undeveloped areas into agricultural land to grow more beef cattle.

Thank goodness. Otherwise, we might we watching “Hippo Die-Nasty” instead of “Duck Dynasty” on television.
