D. T. Max has vividly sketched humans in competitive mode, harnessing tournament rules to address the aggressions of this introduced species. In the decades-long perspective, lionfish are winning the bigger tournament by adapting and expanding their range; but we admire the drive to end that success:

Killing Invasive Species Is Now a Competitive Sport

In the Panhandle, where swarms of lionfish gobble up native species, a tournament offers cash prizes to divers skilled at spearing one predator after another.

After writing about some of Cyprus’ environmentally destructive actions, it feels good to hear about these positive organized efforts to eradicate this marine threat. Lionfish have long been on our radar, but this is the first we’ve heard of their spread through European waters.

Perhaps a new venue for eradication idea exchange is in order!

Cyprus begins lionfish cull to tackle threat to Mediterranean ecosystem

Cyprus  has held its first organised cull of lionfish after numbers of the invasive species have proliferated in recent years, threatening the Mediterranean ecosystem and posing a venomous danger to humans.

“They’re actually very placid,” said Prof Jason Hall-Spencer, a marine biologist, after spearing 16 of the exotic specimens in the space of 40 minutes in the inaugural “lionfish removal derby” off the island’s southern coast. He added: “The problem is they are not part of the natural ecosystem and we are seeing them in plague proportions.”

Lionfish, armed with venomous dorsal spines that enable them to deter predators, are more normally associated with warm tropical waters of the South Pacific and Indian Ocean. Almost two decades ago the non-native tropical fish began to enter US waters, appearing in the Atlantic after pet owners started releasing outsized lionfish from home aquariums into the sea. Now they have reached Europe. In 2012, after initial sightings off Turkey, Israel and Lebanon, they were spotted off Cyprus. Three years later they had appeared further south in Greece, Italy and Tunisia, testimony, scientists say, to their ability to both enter new territories and spawn at record rates.

As numbers proliferate, so have fears of the flamboyantly coloured fish posing the biggest ecological setback to ecosystems in the Mediterranean – which is already under pressure from pollution, tourism and over-exploitation. In the EU, Cyprus has become “the first line of defence” against the lionfish invasion. Continue reading →

A Big Fish Story We Can Get Behind

/ Phil Karp / Leave a comment

Cool video from the Red Sea of a moray eel (Gymnothorax javanicus) preying on a lionfish (Pterois miles).

Morays are quick to chow down on lionfish carcasses in the Caribbean and will readily accept (or steal) lionfish off of a spear (although such feeding is a BAD idea as it causes them to associate divers with food).

Let’s hope they will begin to hunt lionfish o their own in the Caribbean as well.

The citizen science activities we’ve discussed during this past year go beyond bird counts and uploading data. In the case of the invasive lionfish, participants have to really get their feet wet, so to speak.

In addition to creating a viable income in local fishing communities affected by the lionfish invasion by the developing the market for the meat and the spines, numerous organizations invite volunteers to assist in the eradication process itself. Continue reading →

We’ve been posting on the environmental impact of the invasive lionfish ever since contributor Phil Karp took on the project of building a demand for the notoriously difficult to catch fish. Helping to build a market for the delicious meat and beautiful spines created income for local fishermen and their families in numerous areas of the Caribbean.

ReefSavers was created with all these goals in mind. Founded to gain control of the Lionfish population in the southeast US and Caribbean, they work toward both harvesting and developing a stable market in which supply can always meet the current demands. By unifying

the organizations working to control the Lionfish outbreak into a cohesive market place. Channeling all harvested Lionfish through a centralized market place will allow for a more stabilized fishery. With the creation of the Lionfish Market Place organizations will have a centralized place to sell their catch and buyers will not have to worry about limited supplies. By opening the Lionfish Market buyers for the whole state of Florida will be connected with a more constant supply, in turn this access will help to grow the industry and put revenue into the hands of the people trying to fight the outbreak.

The ReefSavers team came up with innovative strategies to help with supply and demand logistics, fanning the market for the fish for both chefs and more importantly, consumers. Welcome the Lionfish Invasion Tour in Gainsville, Florida! Continue reading →

This is issue has been on our radar for some time, in most part due to contributor Phil Karp‘s posts on his work with groups in Belize and other parts of the Caribbean focused on this goal. The concept of “If You Can’t Beat ’em, Wear ’em” carries a powerful message of innovative practices to manage the invasive species that’s causing havoc in the southern Atlantic and Caribbean waters.

Lionfish Trap Tests in Pensacola Show Promise

There is no shortage of lionfish posts here, as a quick search of the site will show. Off the coast of Pensacola, Florida, we’re encouraged to hear that there is good news from the trapping scene – rather than speargun hunting, which has certain limits. Although we aren’t told how the tested traps avoid catching other fish than the target, it sounds like progress is being made. Jeremy Morrison reports:

Eighteen miles out into the Gulf of Mexico, lying in wait about a hundred feet deep, are a collection of contraptions that have Steve Gittings “pretty encouraged” and “really kinda jazzed.”

“I’m kinda pleasantly surprised about what we found in Pensacola,” said Gittings, science coordinator for the the National Oceanic and Atmospheric Administration National Marine Sanctuary.

Since July, Gittings and a his collaborators have been conducting tests on some prototypes of a lionfish trap he designed. In late August, the scientist wrote a report detailing what he considers to be the initial successes revealed during this summer’s testing.

Lionfish Removal and Awareness Day Festival

I’ve posted previously about the lionfish invasion that is threatening coral reef and other marine ecosystems throughout the Caribbean, Gulf of Mexico, and Southern Atlantic Seaboard of the United States. As I’ve noted in earlier posts, it is the general consensus of the scientific and conservation community that eradication of lionfish from the Atlantic is impossible. However, there is growing evidence that systematic removal efforts can be effective in controlling lionfish populations and in reversing their negative impact on reef health. The challenge faced by marine protection agencies and marine resource managers is how to undertake these removals on a regular and financially sustainable basis. I’m convinced that this challenge can best be met by an integrated approach involving coordinated action by public and private actors complemented by the creation of markets for lionfish products.

All of these elements were in evidence at the Lionfish Removal and Awareness Day festival in Pensacola, Florida which I attended last month. Organized by the Florida Fish and Wildlife Conservation Commission (FWC), the two-day event included a lionfish derby (with more than 8,000 lionfish removed by volunteer divers), lectures about the invasion and the threat that it poses, lionfish cooking and tasting, and sale of lionfish products.

Notable among the sponsors of the event was Whole Foods, which had announced a few weeks earlier that it was going to begin selling lionfish at its stores in California and Florida. The move by whole foods was sparked by the decision late last year of Monterey Aquarium’s Seafood Watch program to list lionfish as a best choice under its sustainable seafood recommendations, citing the invasive nature of the species. As I had noted in a previous post, Seafood Watch had previously declined to list lionfish due to the absence of an established commercial fishery, but to their credit, the group responded to what they described as a “grassroots campaign” and revisited the issue. Moreover, since taking the decision to list lionfish, Seafood Watch has been active in raising awareness about the invasion and in promoting lionfish consumption. Continue reading →

Lionfish Jewelry Update – Caribbean Gulf and Fisheries Institute Conference

/ Phil Karp / 2 Comments

I’ve posted previously about the emergence of lionfish jewelry as one of several market-based approaches to controlling the invasion of this non-native species which poses an unprecedented threat to marine ecosystems in the Western Atlantic.

Last month I had the opportunity to make a presentation on lionfish jewelry at a special workshop on lionfish management that was held during the annual conference of the Gulf and Caribbean Fisheries Institute, in Panama. The conference program also included a full-day lionfish research symposium and a lionfish research poster session, both of which gave me an opportunity to learn more about the science aspects of the lionfish invasion and some of the latest findings on lionfish biology and behavior and to meet some of the leading researchers on these subjects.

The lionfish management workshop, which was organized by the United Nations Environment Program’s Caribbean Regional Activity Center on Specially Protected Areas and Wildlife (SPAW-RC) and the International Coral Reef Initiative (ICRI), brought together marine scientists, managers of marine protected areas, fishermen, and representatives of international organizations to share experiences and lessons learned with respect to strategies for controlling the invasion.

I’ve posted previously about the emergence of lionfish jewelry as one of several market-based approaches to controlling the invasion of this non-native species which poses an unprecedented threat to marine ecosystems in the Western Atlantic.

Last month, for the third year in a row, I spent two weeks in Belize where I had a chance to get an update on how the market is developing.  I started my visit in Placencia, which is home to Kaj Assales, the most successful of the lionfish jewelry artists in the country, with her own jewelry line which she sells through her boutique as well as online.  It was my first chance to visit her shop and to see some of her new designs.

Next I spent a week in the Sapodilla Cayes with ReefCI, the NPO that I first collaborated with to help jump-start the lionfish jewelry market in the country.  This gave me a chance to practice my lionfish spearing skills, as the ReefCI team and visiting volunteers continue to remove several hundred lionfish per week dissecting a sample of 30-40 of these for stomach content. Data on size, sex, and stomach content is provided to the Belize Fisheries Department and has been a valuable input to its national lionfish control strategy.  Coincidently, ReefCI’s lionfish control program was profiled in the August issue of United Airlines magazine; not only a nice recognition of the group’s efforts, but also a great boost for raising awareness about the lionfish invasion.

Flower Garden Banks Lionfish Invitational

/ Phil Karp / 1 Comment

I have posted previously about the lionfish invasion and the threat that it poses to marine ecosystems in the Western Atlantic. In an earlier post, I noted that there is increasing evidence that regular removals can be effective in controlling lionfish infestation, allowing native fish populations to recover. Removals are being undertaken via organized efforts such “lionfish derbies” and other forms of sanctioned fishing tournaments as well as via market approaches that create commercial incentives to harvest the fish.

While marine protection agencies are generally supportive of these efforts and are indeed engaging in removals themselves, they lack the data and evidence needed to make informed decisions about the optimal mix of approaches and the level of effort and resources needed to effectively control the invasion. I recently had the opportunity to participate in a research expedition aimed at helping to address this gap. I was fortunate enough to be selected to join 29 other volunteer citizen scientists, professional/semi-professional spear fishers, and marine scientists for a fish survey and lionfish culling effort in the Flower Garden Banks National Marine Sanctuary. Situated about 100 miles off the coast of Texas, the sanctuary is home to a unique ecosystem with almost 300 species of fish, 21 species of coral, and several other invertebrate species. Lionfish are being observed with increasing frequency within the sanctuary, a cause for concern by the sanctuary’s managers. They have previously undertaken periodic culling of lionfish, but the recent effort was the first time that removals were undertaken in a systematic fashion. Continue reading →

Support Needed for Lionfish Jewelry Workshop

For the past several years, I have been involved in helping to develop markets for lionfish jewelry as a way of addressing the threat posed by this invasive species, which is severely compromising the health of coral reefs throughout the Caribbean by eating reef-dwelling fish. Belize is home to the second largest barrier reef in the region, and its lobster and conch fisheries could really benefit from a break of overexploitation, so encouraging lionfish fishing in any way possible will promote reef recovery.

My last post, in fact, was about my trip to northern Belize last summer, when I collaborated with two local NGOs in Belize to train women from a coastal community on how to create lionfish jewelry. This August, I will again be joining one of these groups – Blue Ventures, for a lionfish jewelry workshop for women from other areas. As you can see from the pictures here and in my previous posts, lionfish fins, tails, and spines are beautiful; they’re also relatively low-cost to transform into jewelry. These parts of lionfish were previously discarded, but when kept and transormed into jewelry the value of landed lionfish catch increases by up to 40%, creating additional incentives for fishers to target and remove lionfish Continue reading →

Fighting Invasive Lionfish – Update

/ Phil Karp / 8 Comments

I’ve posted previously about the lionfish invasion that is threatening coral reef and other marine ecosystems throughout the Caribbean, Gulf of Mexico, and Southern Atlantic Seaboard of the United States. Availability and dissemination of information about the invasion was recently given a big boost through launch of the Invasive Lionfish Web Portal The portal is a collaborative effort of a number of partners, led by the Gulf and Caribbean Fisheries Institute. It is a great resource, providing links to a range of information about the invasion, including journal articles, videos, photos, recipes, a Twitter feed, etc..

Another recent development has been the release of a draft United States National Invasive Lionfish Prevention and Management Plan. Developed by the U.S. Government’s Aquatic Nuisance Species Task Force, the plan is intended to help coordinate the actions of the various government agencies and other stakeholders involved in dealing with the invasion. While such a plan is long overdue, and in that sense is welcome, I’m quite disappointed that the plan largely ignores, and indeed implicitly discourages, an important element of an effective strategy for addressing the invasion – namely the use of market-based approaches.

As I’ve indicated in my previous posts, the Atlantic lionfish invasion is a unique problem that requires innovative solutions. Continue reading →

In Part 1 of this post I wrote about my recent visit to Belize to help with further development of the nascent  market for lionfish jewelry; one of several market-based approaches to addressing the threat to Southwest Atlantic marine ecosystems posed by the invasion of this non-native species. I noted that the market is most advanced in the area around Punta Gorda, in Southern Belize, in large measure due to the support provided by ReefCI which has provided training on jewelry making to a group of local women and is supplying them with lionfish spines, fins, and tails as well as marketing assistance.

While ReefCI’s involvement has been instrumental in getting things started, further development and expansion of the market will require engagement with artisans and women’s groups in other parts of the country, particularly areas closer to major tourist markets. Interventions are also needed to develop a reliable and sustainable supply chain for lionfish jewelry production and sales. I was pleased to hear from one of the jewelry makers in Punta Gorda that a local fisherman had approached her about selling lionfish tails. This was music to my ears, as one of the motivations behind the lionfish jewelry idea has been to up return to fishers in order to create added commercial incentive for them to hunt lionfish (the fish cannot be caught using conventional fishing methods such as hook and line or nets, but must instead be speared or hand-netted by diving).

I’ve written in previous posts about the initiative to develop a market for lionfish jewelry as one of a number of commercially sustainable approaches to fighting this invasive species that is threatening marine ecosystems throughout the Caribbean, the Gulf of Mexico, and the Southern Atlantic seaboard of the United States. In my last post, I mentioned that the idea is beginning to take off in Belize.  I was able to observe this first-hand last month, spending two and a half weeks in the country.  During my stay I had the opportunity to meet local artists who are making lionfish jewelry and to participate in several workshops to share techniques and designs.  Continue reading →

In Part 1 of this post regarding market-based solutions to fighting the lionfish invasion that is threatening coral reef and other marine ecosystems throughout the Caribbean, Gulf of Mexico, and Southern Atlantic Seaboard of the United States, I wrote about the challenge of developing commercially sustainable strategies for undertaking the systematic removals that are needed to keep lionfish populations under control. I discussed the need to develop a series of vertical markets, pointing to promotion of lionfish as a seafood choice as the most obvious of these. Capture of juvenile lionfish for the aquarium trade as another.  A third market, and one in which I’m personally involved, is use of lionfish spines and tails for jewelry and other decorative items.  Continue reading →

Controlling Invasive Lionfish – Update on Market Solutions: Part 1/2

/ Phil Karp / 13 Comments

 

I’ve posted previously about the lionfish invasion that is threatening coral reef and other marine ecosystems throughout the Caribbean, Gulf of Mexico, and Southern Atlantic Seaboard of the United States. As I noted in earlier posts, it is the general consensus of the scientific and conservation community that eradication of lionfish from the Atlantic is impossible. There have been some anecdotal reports that native predators such as groupers and snapper are beginning to recognize lionfish as prey, but there is no systematic evidence, as of yet, of widespread predation. So the conclusion remains that human intervention is the only way to keep lionfish populations in check. The good news is that there is growing evidence that systematic removal efforts can indeed be effective in controlling lionfish populations and in reversing their negative impact on reef health. A study published earlier this year found that populations of snapper and grouper rebound by 50-70 percent once lionfish are removed. And it isn’t necessary to remove 100 percent of lionfish for recovery of native fish populations to take place; the study found that reduction of lionfish populations by as little as 75 percent will do the trick. This is important, given difficulties in reaching lionfish at depths beyond the limits of divers.  Also, removal efforts may become more difficult over time, as lionfish on reefs where regular culling takes place begin to wise up and hide from divers (click here for a cute poetic rendition of findings of a study on this behavioral adaptation).

Thus the challenge is to find a sustainable basis on which to undertake the systematic removals that are needed to keep lionfish populations under control. Continue reading →

In earlier posts about my volunteer experience in Belize with ReefCI, I talked about the lionfish invasion that is threatening coral reef and other marine ecosystems throughout the Caribbean, Gulf of Mexico, and Southern Atlantic Seaboard of the United States, and noted that, at least for the foreseeable future, human intervention, particularly the establishment of a commercial fishery for the species, appears to be the only solution to keep the invasion under control.

I mentioned the idea of lionfish jewelry as a possible way of increasing the economic return to fisherfolk who may otherwise be reluctant to go after lionfish given the difficulty of catching them (the fish must be harvested by spearing or hand netting rather than through traditional methods such as lines or nets). I’ve been pleased to learn that at least one artisan in Belize has picked up on the idea, using some of the lionfish spines that I collected while I was there. She has already crafted some beautiful earrings (see photo above) and is working on other jewelry items as well as decorative mirrors. Elsewhere, jewelry crafted from lionfish tails and fins is being sold online, and through a retail outlet in Curaçao.  Continue reading →
