Portuguese Man o War…spotted worldwide

The Portuguese Man o’ War  can be found anywhere in the open ocean (especially warm water seas), but they are most commonly found in the tropical and subtropical regions of the Pacific and Indian oceans, and the northern Atlantic Gulf Stream. The Man o’ War has been found as far north as the the northeast end of the Gulf of Maine.

They wash ashore along the northern Gulf of Mexico and the east and west coasts of Florida.  An abundance of Portuguese Man o’ Wars can be found in the waters of Costa Rica, especially in March and April.  They have been spotted recently off the coast of Spain, Ireland, in Welsh waters and in the Mediterranean near Corsica and Malta.

They are also frequently found along the east coast of South Africa, (particularly during winter storms if the wind has been blowing steadily on-shore for several hours), as well as around the Hawaiian Islands.  Strong onshore winds may drive them into bays or onto beaches. It is rare for only a single Portuguese Man o’ War to be found; the discovery of one usually indicates the presence of many as they are usually congregated by currents and winds into groups of thousands. Man o’ Wars typically travel in groups of 1,000-plus.

Ocean Care Solutions Lionfish Sting 1st Aid Kit provides safe and effective sting relief

Pterois volitans and P. miles
Native range: Indo-Pacific and Red Sea
Invasive range: East coast of the United States and Caribbean sea

Some say that the invasion started in Miami, when Hurricane Andrew smashed an aquarium tank in 1992. But you can’t blame the weather: records of wild lionfish in Florida date back at least to 1985. This popular aquarium fish may have been released by fish enthusiasts tired of having a relentless predator in the living rooms, silently dispatching their other fish. And now that exotic predator is spreading north to New England, south to Panama and throughout the Caribbean, feasting on juvenile snapper and grouper along with algae-eating parrotfish as they go–-species which help keep reefs healthy. The lionfish is the first marine fish invasion in the western Atlantic.

Lionfish Range in the US.

Marine biologists are shocked at the speed of their spread in just a decade and at their population densities. Few fish species have established in the wild, let alone so successfully. Suddenly, they’re an abundant reef fish from the Bahamas to Rhode Island. Overfishing of predators like the grouper may be part of the story. Reef destruction and trophic cascade are possible outcomes. The only range limits appear to be colder and fresher waters.

A female lionfish produces two million eggs a year, so not only does it seem unlikely the species can be successfully eradicated, even slowing the growth rate is a challenge. Because lionfish eat just about anything that fits in their mouth while larger native fish don’t seem to recognize lionfish as prey, some experts say humans are the only predators left to call upon.

Common lionfish (Pterois miles)

As of 2010, the Florida Keys National Marine Sanctuary has given out licenses to divers to kill the species inside the property. Reef Environmental Education Foundation (REEF) hosts a series of “Lionfish derbies” offering prize money  largest, smallest, and highest number caught; and publishes the Lionfish Cookbook, aimed at introducing chefs to what NOAA calls a “delicious, delicately flavored fish” similar in taste to snapper and texture to grouper. Lionfish have venomous fin spines––an uncommon feature on East coast species–-making them top predators and a danger to fishermen and divers. (And more expensive than many other fish on the menu, someone has to remove those venomous spines.)

The Lionfish 1st aid kit comes with everything you need to effectively treat your marine sting.

Product Review – Jellyfish Sting Relief Solution

About Ocean Care Solutions

Ocean Care Solutions’ (OCS) first aid products were developed by Kevin, a certified scuba diver. Kevin noticed that there was no convenient, proven medically effective, first aid products for stings from the Lionfish, the Man of War, the Sea Urchin, the Stingray, Fire Coral and Jellyfish. For two years Kevin consulted with international marine science and emergency medical communities to develop what they refer to as ‘the definitive Gold Standard’ for sea sting injuries. All OCS’s products have been developed without the reliance of myths, home remedies or guesswork.
Ron at OCS got in contact with Dive Flag App in a hope to have their product reviewed and publicized to Scuba Divers around the world. After initial discussions OCS sent us, here at Dive Flag App, a package containing a few hundred samples to test and distribute to other Dive Flag App members.  Today we had the opportunity to test their most ‘popular’ product the Jellyfish Sting Relief Solution (JSR Solution). This was a timely arrangement as Australia is currently experiencing an outbreak of jellyfish including the Blue Blubber Jellyfish (common name).

Product Description – Jellyfish Sting Relief Solution

OCS’s JSR Solution was developed to neutralize the stinging cells of jellyfish. The solution suspends any remaining pain causing nematocysts (stinging cells) from firing.  The directions of use are as follows:
  1.  Rinse the injury with salt water only,
  2.  Shake the spray and simultaneously press down on the top to pump the solution,
  3.  Apply the safe JSR Solution for 3-5 minutes, and then
  4.  Simply scrape away the pain.  Re-apply if necessary.
The application of the JSR solution is to ‘de-activate’ the jellyfish stinging cells. For the best results it is recommended that you apply the JSR Solution as soon as possible after having been stung. Delay in the use of this product limits effectiveness.
The JSR Solution comes in a small and convenient spray bottle made with medically recommended 5% acetic acid for the best results.

Product Trial

Dive Flag App were naturally skeptical about the effectiveness of OCS’s JSR Solution and so we decided to test the product out. Before reading further it is important to note that Dive Flag App did so under the supervision of trained emergency personnel and in no way is Dive Flag App suggesting that other members perform the following test.
Frank Vorster located two Blue Blubber Jellyfish in the Gold Coast Seaway, Queensland, Australia. He proceeded to sting himself in two ‘similar’ locations by lightly pressing up against the tentacles of the two jellyfish as they floated by. To one location he applied the JSR Solution and to the other he applied nothing. Eager to test the product out – others part-took in the experiment too.

Observations

  1. Within one minute, the stinging sensation on the hand with the JSR Solution started to subside whilst the second location’s continued to intensify as more stinging cells activated.
  2. After five minutes the stinging sensation on the location with the JSR Solution had all but faded completely, whilst the stinging sensation of the second location continued.
  3. Frank wiped the location with the JSR Solution as directed. The location where he had applied the JSR Solution appeared unaffected. Whilst having  wiped off the second location in a similar fashion had only activated the remaining stinging cells, effectively reactivating the sting.
  4. For a further 25 minutes Frank felt the stinging sensation on the second location whilst the location where the JSR Solution was applied felt “like it was never stung”.

Product Review

The JSR Solution performed as OCS had claimed. The product was easy to apply and immediately effective. The quality is guaranteed by OCS’s Californian manufacturing facility. A single 1oz bottle can be used to relieve 4 stings and the 4oz bottle can relieve up to 12 stings. With a shelf life of over 2 years the product can be stored without concern.
  • Price: 5/5
  • Effectiveness: 5/5
  • Quality: 5/5
  • Product Recommendation: Don’t get stung without it! Don’t go diving without it!
Dive Flag App highly recommend that all beach going, water sport activists and especially scuba divers keep a bottle of the solution in their bag. The product is incredible effective and useful.

Where to Buy the Product

Dive Flag App is so impressed with the effectiveness of the solution, we have worked out an arrangement with Ocean Care Solutions to become the exclusive distributor for these products. Dive Flag App is currently developing an on-line store where you can buy the product. If you would like a sample, to purchase some units for personal use or become a retailer for these products, simply email us for more information: info@diveflagapp.com .

Lionfish Distribution as of 2012 as reported by the United States Geologic Survey (USGS) with a great deal of data provided by NOAA and REEF.

Invasive Species: Indo-Pacific LionFish (Pterois volitans) in the Atlantic and Caribbean Sea!

GVI Mexico – August Achievements

The invasion of lionfish, native to the Indo-Pacific, into the Atlantic and Caribbean Sea is not only one of the most rapid in marine history but also having extremely detrimental effects to local species and ecosystems.

Recently introduced via un/intentional release, they have spread extremely quickly throughout the Caribbean, since their first sightings around Florida in 2000, they have spread as far south as Venezuela within 10 years1.

While in their native habitat, lionfish breed seasonally, invasive lionfish in the Atlantic have been documented breeding all-year round2. They can produce between 4000 and 30,000 eggs each time they spawn which are then dispersed great distances along oceanic surface currents, during an estimated pelagic larval duration of 20 to 35 days, before settlement3. Unlike other fish species, Lionfish can settle on and inhabit nearly all marine habitat types and depths between surface levels to over 300m, in temperatures between10-35 degrees Celsius4,5. However, with the rising sea temperatures due to global warming, this potentially invasive region is increasing. Lionfish are also generalist carnivores that can consume over 70 species of fish, up to half their own body length, including commercially, recreationally, and ecologically important species6. On heavily invaded sites, lionfish consume native fish at unsustainable rates. As such, food competition can also lead to depleting food sources for native carnivores.

Here at Pez Maya we have been collecting information on the invasive lionfish so as to document its effects on the local ecosystem. So far this year the average number of sightings per dive per week has been slowly increasing.

As well as a steady increase in the average number of sightings per dive, there is also a noticeable increase in the sizes of lionfish seen on our dive sites. This general increase in size supports theories that invasive lionfish are larger than they are in their native ranges7, suggesting higher levels of local prey consumption and lionfish reproduction this year. In fact, we caught three individuals, one male and two females, that had fully developed and spawning capable gonads or very developed gonads nearing spawning capability.                                                                                                                

Lionfish can inhabit nearly all habitat types, including important nursery areas such as mangroves and lagoon areas, and other areas with high levels of trophic interaction such as the fore-reef and reef crest. As such we have frequently observed lionfish within the reserve at our inner-reef dive sites, such as “Gardens”, which are commonly used as a nursery habitat for juvenile reef fish.

Invasive adult lionfish, however, have been documented as having a preferred microhabitat of complex topographical structures, especially overhanging structures, and lots of coral cover8, such as our dive site “Special K”. As such, the invasive lionfish exhibited similar patterns of microhabitat occupancy as two local, and already over fished, species; the Grouper and Snapper complex, as seen at our local dive site “Hang 10”. The additional stress put on these species through this direct food competition is hindering any efforts to replenish the declining Grouper and Snapper populations.

As discussed before, on heavily invaded reefs lionfish can consume prey faster than their production on, or recruitment to, the reef. As such, the additional stress put on these species through this direct food competition is hindering any efforts to replenish the declining Grouper and Snapper populations. Also, the lionfish is having a negative impact on the Meso-American barrier reef system through the unsustainable consumption of newly recruited herbivorous species by invasive lionfish is limiting algal grazing on a reef system that is already in threat of a shift to an algal dominated reef.

Lionfish feed primarily on teleosts, fish with bony skeletons, which include the majority of the local marine species, and few other crustaceans, primarily shrimps, more commonly consumed by smaller classes of lionfish. However, lionfish are generalist consumers and will quickly abandon their usual diet for any abundant food source.

Because lionfish captured and removed from an area would “be replaced largely through larval recruitment rather than migration of older individuals”9, “localized control efforts would need to be carried out frequently in order to maintain a  younger, smaller population”10, which can be very costly and  makes eradication programs extremely difficult.

However, the data collected here is very useful for future planning of local control efforts and will hopefully be used to co-ordinate our future lionfish control efforts which, if implemented well, can control local populations and even generate income for local communities. Also, and possibly more importantly, lionfish ceviche is a very welcome addition to base cuisine!

How do Jellyfish sting??

The science of cnidocytes and nematocysts

Sea jellies don’t sting through electricity or by touch. A sea jelly sting through a special type of cell called a Cnidocyte, there are three types of cnidocytes currently known. Spirocysts which entangle their prey, Ptychocysts which build tubes for tube anemones and the most well known Nematocysts. Nematocysts consist of a toxic barb which is coiled on a thread inside the cindocyte, when triggered the barb is ejected almost instantly taking only 700 nanoseconds to fire and firing with a force of five million g’s. A cindoctye can only fire once, and must be replaced when fired a process that could take 2 days.

Sea jellies sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes, which are characteristic of all Cnidaria. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom, yet only some species’ venom cause an adverse reaction in humans. When a nematocyst is triggered by contact by predator or prey, pressure builds up rapidly inside it up to 2,000 pounds per square inch (14,000 kPa) until it bursts. A lance inside the nematocyst pierces the victim’s skin, and poison flows through into the victim. Touching or being touched by a jellyfish can be very uncomfortable, sometimes requiring medical assistance; sting effects range from no effect to extreme pain to death. Even beached and dying jellyfish can still sting when touched.

Scyphozoan jellyfish stings range from a twinge to tingling to agony. Most jellyfish stings are not deadly, but stings of some species of the class Cubozoa and the Box jellyfish, such as the famous and especially toxic Irukandji jellyfish, can be deadly. Stings may cause anaphylaxis, which can be fatal. Medical care may include administration of an antivenom.

Detailed Video of firing nematocysts

Jellyfish are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.

Jellyfish are found in every ocean, from the surface to the deep sea. A few jellyfish inhabit freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.

Reducing Lionfish Polulations..

Faced with a dramatic reduction of native populations of fish–which support fishing and diving recreational tourism–nearly everyone is working to reduce the lionfish populations. From spearfishing to hook and lining, any method to get them out of the water is seen as a step in the right direction. Citizen organizations like LionFishHunters and The Lionfish PSA have sprung up to educate the public and direct us toward steps necessary to control this opportunistic species.

Especially in the Florida Keys, locals are trying hard to put lionfish on the menu in seafood restaurants, hoping we can eat them into submission. Lionfish is reported to have an excellent taste and is often compared to hogfish or snapper. It’s not dangerous to eat because the poison is only contained in the spines. The meat is safe to eat.

Want to know how to clean and cook a lionfish? Here’s a great 4 minute video to show you how:

Ocean Care Solutions Does Its Lion Share Of Work

Ron Adley announced a new Ocean Care Solutions for Lionfish Kit. “The kit will be available by January 15th. It is another product in our increasing line of marine sting products including a newly formulated jellyfish sting relief spray.”Lionfish are colorful marine fish with venomous spiky fin rays. Its presence is increasing around the seas of the world and present a danger to fishermen, divers and swimmers. Its venom can lead to extreme pain, nausea, vomiting, fever, breathing difficulties, convulsions, dizziness, redness on the affected area, headaches, and numbness although its venom is rarely fatal.

As Adley knows well from his travels, lionfish stings can produce discomfort over several days as well as severe allergic reactions that can cause breathing difficulties, swelling of the tongue, and slurred speech.

Ocean Care Solutions‘ products were nominated for the 2012 World Open Water Swimming Offering of the Year.The nomination of Ocean Care Solutions reads, “Care is its middle name. Ocean Care Solutions is working hard to help stem the tide of the pain and discomfort caused by stinging organisms. Its products enable comforting relief from a number of jellyfish, Portuguese man o war, sea urchins, fire coral and stingrays.

Ocean Care Solutions goes beyond supplying a wide range of first aid kits that are widely acclaimed the world over. It provides information, a constant source of education about the global proliferation of jellyfish in the world’s oceans.

For its desire to relief pain by working directly with the stakeholders in the open water swimming world, for its wide range of soothing solutions, for its sharing of information about the sea stingers that are a growing menace in the aquatic world, the Ocean Care Solutions line-up is a worthy nominee for the 2012 WOWSA Open Water Swimming Offering of the Year.”
