Invasion of lionfish could impact local anglers

TARBORO — Are lionfish quickly becoming a nuisance and threatening our native North Carolina reef fish populations?  Those experts in the marine sciences give an emphatic yes.  The nagging question begging an answer is what to do about it.

Known in the scientific community as Pterois volitans, lionfish are typically one-pound, foot-long, reef bottom feeders with venomous spines that have no natural predators, and are starting to overpopulate, damaging the ecological balance of the reefs off our North Carolina coast.

Could this be an ecological disaster that will resonate in due time in the commercial and sport fishing community?  Absolutely.  Experts theorize lionfish will continue to multiply greatly and impact reef life negatively.

Lionfish reach sexual maturity very quickly.  A single female spawns 2 million eggs a year.  As fish go, they have a long life-span, exceeding several decades.

Native to tropical Pacific and Indian oceans, the lionfish problems and concerns are relatively new to this area, and have been only recently on North Carolina marine scientists’ agendas and watch lists.

For many, introduction to lionfish has been through commercial and home aquariums.  These candy-striped fish with venomous spines are interesting to observe in an aquarium atmosphere.

Known to be aggressive with voracious appetites, they feed in the wild on juvenile lobsters, snapper, grouper, and other bottom reef fish fingerlings and aquatic nurseries, consuming 10 times as much as a same size fish.  Some 70 different species of fish and aquatic growth are thought to be impacted.  Most lionfish prey are commercially, recreationally, and ecologically important to NC coastal fisheries.

With no natural predators and a population that is quickly escalating out of control, some areas have put a bounty on lionfish.  Spear fishermen find them to be a plentiful, stationary target around reefs, wrecks, and structure.  They are rarely caught on hook and line, and are difficult and inefficient to harvest commercially.  Spear fishing appears to be the most effective method to catch them.

A diving club held a lionfish spear fishing tournament off Morehead City earlier this summer with cash prizes for lionfish, then used the resulting catch to introduce the unique tasting, flaky white meat to diners.  Of course, handling lionfish in and out of the water should be done with protective gloves due to those prickly venomous spines.  Much of the toxicity dissipates at their death, and when cleaned, detoxified, and prepared properly, lionfish enjoy an excellent table fare reputation and are thought to be a special delicacy.

The web site www.reef.org seeks to conserve marine ecosystems by educating and informing marine enthusiasts and they, tongue-in-cheek, suggest the solution to the dilemma is to, “Eat ‘em to beat ‘em.”  Not so ironically, that was the name given to the recent lionfish tournament in Carteret County.

In summary, lionfish are here to stay.  They are a real problem and a definite threat to the ecological balance of our coastal NC reefs and related fisheries.  What can we do?  Encourage legislators and marine science officials to help control and keep lionfish in check.

Perhaps something as small as purchasing a lionfish fillet at the fish market or restaurant would drive demand and reduce supply.  All of us need to do our part to control the “roar” in this lionfish dilemma.

    It took a year, but Wifey and I finally met Bob Daw at Blounts Creek. An avid angler, Bob writes an interesting weekly blog about Blounts Creek fishing.

  • Rick-Goines.jpg National hunting, fishing day Saturday September 28

    North Carolina joins the nation Sept. 28 to celebrate National Hunting and Fishing Day.  Your NC Wildlife Resources Commission has family oriented activities scheduled statewide to help you welcome this enjoyable occasion. For more information about the event, call 919-707-0010 or go to www.ncwildlife.org.  Visiting that NCWRC website regularly is always a good idea to stay on top of current, solid outdoor info and intel.
    Fall fishing is hard to beat in Eastern North Carolina.  I would stack up our fall Eastern NC fishing action, freshwater and saltwater, against fishing anywhere.

  • Battle Park is a cornucopia of nature

    Fifty-seven acre Battle Park, in the heart of Rocky Mount, is named after the Battle
    family of Tarboro, founders of Rocky Mount Mills. Water-powered, the mill dam was hewn of the rocks of the Great Falls, past the westernmost point of Edgecombe County.

  • Take a kid fishing this summer

    As you put the final touches on your summer vacation plans, consider a fishing outing for the youngsters.  They might not remember or appreciate that expensive beach cottage rental, or that high-dollar meal at that trendy waterfront restaurant, but I would bet a pretty penny they will recall every detail of a fun-filled family fishing experience.
    Just about anywhere you chose to go this summer will offer fishing

  • Shad Season in Review

    All things considered, 2013 was a good shad season, thoroughly enjoyed the fishing activity and usual camaraderie among shad fishing friends. Shad fishing to me is about so much more than just catching fish.  It’s a total package of enjoyment as it captivates and dominates my life February through May.
    Wayne Harrell kicked off the season winning the first shad contest catching his hickory shad on a cold 19-degree Saturday morning, February 2.
    The shad hole on East River Road in Tarboro was a little disappointing this year. Untimely flood waters might have limited our regular peak run. Fish were caught and we had some good days, but not the action we have experienced in past years.

  • Banner Day at Battle Park

    Sunday was Mother’s Day.  I am not a mother, but I played one in a school play years ago, so I figured that entitled me to go fishing on Mother’s Day. Need an excuse or rationalization to go fishing? Check with me, I’ve got plenty!
    After suffering through 2-3 days of a rain induced swollen, unfishable Tar River at Battle Park in Rocky Mount, it was jackpot time on Sunday. Without a doubt, I had my best white shad fishing day ever, fishing from sunrise to early evening. Action was good all day, with a little lull for about 2-hours in the heat of the afternoon.
    I am proud to report to you that I enjoyed a 50-fish day. I caught a personal best 46 white shad, 3 hickory shad, and foul-hooked a very angry, upset 3-foot gar.  I thought I had two large white shad, or maybe a big rockfish, so I was a little surprised to see Mr. Gar.  It was like reeling in an uncooperative 2x4 piece of lumber.

  • NCWRC enforcement officers doing a great job

    North Carolina Wildlife Resource Commission has two enforcement officers assigned to each county. That’s 200 dedicated, educated, and highly trained individuals protecting our North Carolina environment and natural resources. To become an enforcement officer applicant, one must participate in a highly competitive selection process. A typical candidate is required to pass extensive background and psychological screening. Also included is a vigorous 19-week training academy that is patterned after a military boot camp, with an emphasis on physical fitness.

  • Tight Lines declares Ginger Perry of Nashville the shad queen

    One of my favorite places to bank fish is the boat ramp at Battle Park in Rocky Mount. I have met a lot of interesting people there. Three or four times this season, I have watched this amazing lady, Ginger Perry, fishing with her friend, Big Kelly, for white shad. Simply put, she is one good angler! She casts and retrieves like a pro, and always catches her fair share of fish. Maybe a few more than her fair share! This lady can flat-out fish!
