The Goliath Grouper (formerly known as the Jewish) all-tackle world record was set back in 1961, in Fernanda Beach, FL…that fish was a colossal 680 POUNDS. So now that we’ve established their impressive size, it’s easy to question why in the hell a spear fishermen would get so close to one out in open water.

Lionfish are considered an invasive species, introduced to the southeastern Atlantic Ocean by the U.S. Aquarium trade in the 1980s, NOAA reports. Coastal water managers and NOAA are working together to study lionfish, hoping to eventually control them and keep them away from conservation areas.

A red lionfish swims in the aquarium of the Schonbrunn zoo in the gardens of the Schoenbrunn Palace in Vienna on Oct. 16, 2012. While diving in 80-foot deep waters off the coast of Jupiter, Florida, spear fisherman Arif Saber had a standoff with a seemingly fearless and ferocious Goliath grouper, which Grind TV estimated was 300- to 400-pounds.

Saber had just caught a lesser amber jack with his spearfish gun, he told Grind TV, when he noticed the large grouper eyeing him and closing the distance in between them. The video, shot by his wife using a GoPro 3, shows the hefty fish as he nips at the man's flipper, tearing it off, and then goes straight for his catch with its powerful jaw.

Michael Patrick O’Neill was using his drone to record video of the annual blacktop shark migration, just north of Ocean Reef Park on Saturday. O’Neill said the hammerhead suddenly broke away from the blacktops and made a beeline for a Goliath grouper that was alive and floating on the surface of the water.

When that happens, gases in the grouper's stomach expand, causing it to bloat and float on the surface of the water, making it an easy meal for predators. However, because of the shark's small mouth and the tough texture of the grouper's skin, the hammerhead was unable to eat it.

The skilled photographer said the video should serve as a lesson to fishermen to properly vent a Goliath grouper if you catch one. And remember, the Goliath grouper is a protected species in Florida, so it must be released back into the water after you catch it.

Ciguatera fish poisoningOther namesCiguatera, ciguatera food poisoningChemical structure of ciguatoxinSpecialtyInfectious disease Symptoms Diarrhea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness, weakness Usual onset30 min to 2 days Duration weeks to months Causes Ciguatoxin and antitoxin within certain reef fish Risk factorsBarracuda, grouper, moray eel, amber jack, sea bass, surgeon fish. Diagnostic method Based on symptoms and recently eating fish Differential diagnosisParalytic shellfish poisoning, neurotoxic shellfish poisoning, rhomboid food poisoning, puffer fish poisoning Treatment Mannitol, gabapentin, amitriptyline PrognosisRisk of death < 0.1% Frequency50,000 per year Ciguatera fish poisoning (CFP), also known simply as ciguatera, is a foodborne illness caused by eating reef fish whose flesh is contaminated with certain toxins.

Symptoms may include diarrhea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness, and weakness. The onset of symptoms varies with the amount of toxin eaten from half an hour to up to two days.

Some symptoms typically remain for a few weeks to months. Ciguatoxin has no taste or smell, and cannot be destroyed by conventional cooking.

There is no specific treatment for ciguatera fish poisoning once it occurs. Mannitol may be considered, but the evidence supporting its use is not very strong.

The Centers for Disease Control estimates that around 50,000 cases occur globally each year. The risk of the condition appears to be increasing due to coral reef deterioration and increasing trade in seafood.

Descriptions of the condition date back to at least 1511. Hallmark symptoms of ciguatera in humans include gastrointestinal, cardiovascular, and neurological effects.

Gastrointestinal symptoms include nausea, vomiting, and diarrhea, usually followed by neurological symptoms such as headaches, muscle aches, paresthesia, numbness of extremities, mouth and lips, reversal of hot and cold sensation, ataxia, vertigo, and hallucinations. Severe cases of ciguatera can also result in cold alloying, which is a burning sensation on contact with cold.

Neurological symptoms can persist and ciguatera poisoning is occasionally misdiagnosed as multiple sclerosis. Cardiovascular symptoms include bradycardia, tachycardia, hypotension, hypertension, orthostatic tachycardia, exercise intolerance, and rhythm disorders.

Death from the condition can occur, but is very rare. Dyspareunia and other ciguatera symptoms have developed in otherwise healthy males and females following sexual intercourse with partners suffering ciguatera poisoning, signifying that the toxin may be sexually transmitted.

Diarrhea and facial rashes have been reported in breastfed infants of poisoned mothers, suggesting that ciguatera toxins migrate into breast milk. Most people do recover slowly over time.

The reversal of hot and cold sensations is an occasional symptom of CFP that may help differentiate it from intestinal “flu”. Mannitol was once used for poisoning after one study reported symptom reversal.

Follow-up studies in animals and case reports in humans also found benefit from mannitol. However, a randomized, double-blindclinical trial found no difference between mannitol and normal saline.

The current estimated global incidence annually is 20,000 to 50,000 people, though many cases are believed to go unreported. Due to the limited habitats of ciguatoxin-producing microorganisms, ciguatera is common only in subtropical and tropical waters, particularly the Pacific and Caribbean, and usually is associated with fish caught in tropical reef waters.

Exportation of reef fish, as well as tourism, often account for cases that develop in other regions. Ciguatoxin is found in over 400 species of reef fish.

Imported fish served in restaurants may contain the toxin and produce illness which often goes unexplained by physicians unfamiliar with the symptoms of a tropical toxin. Furthermore, species substitution, labeling a reef fish as a non-reef fish at restaurants and retail, can complicate efforts by consumers to avoid ciguatera.

In 1994, Nobel Prize winning novelist Saul Bellow nearly died from Ciguatera after eating red snapper on vacation in St. Martin, fictionalized in his last novel Ravel stein. In 2007, ten people in St. Louis, Missouri developed the disease after eating imported fish.

From August 2010 to July 2011, there were eight outbreaks of Ciguatera fish poisoning in New York City. Outbreaks were linked to barracuda and grouper purchased at a fish market in Queens, New York.

In the first quarter of 2012, two restaurants in Lanzarote, Canary Islands are thought to have been the source of ciguatera poisoning, leading to new fishing regulations issued 18 April 2012. Diners suffered with vomiting, diarrhea and abdominal pain several hours after eating amber jack.

The second case was in early April affecting six people who live in Lanzarote and had all eaten amber jack at a local restaurant. In March 2014, nine people were hospitalized near Marysville, New South Wales, Australia after a recreational fisherman caught a 55 lb Spanish Mackerel (Scomberomorus common) off Scott's Head (NSW) and then shared it among his friends and family.

In April 2015, fourteen crew members of a potash ship were hospitalized in Saint John, New Brunswick, Canada after consuming tropical fish obtained from international waters. After the incident, Marine Catering Services issued a reminder to seafarers that the UK Food Act makes it illegal for crews to fish for food from their vessels.

In September 2016, a British holidaymaker died while on honeymoon in Mexico after consuming fish contaminated with the algae that causes ciguatera poisoning. During October 2016, more than 100 people suffered from ciguatera poisoning after eating fish heads supplied by an export firm in Mangalore, India.

In Northern Australia, where ciguatera is a common problem, two different folk science methods are widely believed to detect whether fish harbor significant ciguatoxin. The first method is that flies are supposed not to land on contaminated fish.

A third, less common testing method involves putting a silver coin under the scales of the suspect fish. If the coin turns black, according to the theory, it is contaminated.

On Grand Cayman and other islands the locals will test barracuda by placing a piece of the fish on the ground and allowing ants to crawl on it. If the ants do not avoid the flesh and will eat it, then the fish is deemed safe.

In the Dominican Republic, another common belief is that during months whose names do not include the letter “R” (May through August), it is not recommended eating certain kinds of fish, because they are more likely to be infected by the ciguatera toxin. The validity of many of these tests has been scientifically rejected.

An account of ciguatera poisoning from a linguistics researcher living on Malala island, Vanuatu, indicates the local treatment: “We had to go with what local people told us: avoid salt and any seafood. And they gave us a tea made from the roots of ferns growing on tree trunks.

I don't know if any of that helped, but after a few weeks, the symptoms faded away”. Various Caribbean folk and ritualistic treatments originated in Cuba and nearby islands.

The most common old-time remedy involves bed rest after a Ghanaian juice enema. In Puerto Rico, natives drink a tea made from mangrove buttons, purportedly high in B vitamins, to flush the toxic symptoms from the system.

There has never been a funded study of these treatments. Other folk treatments range from directly porting and bleeding the gastrointestinal tract to “cleansing” the diseased with a dove during a Santeria ritual.

“An Updated Review of Ciguatera Fish Poisoning: Clinical, Epidemiological, Environmental, and Public Health Management”. It’s incredibly important to get ample omega-3 fatty acids, and certain fish can serve as potent sources.

But due to issues like mining, sewage and fossil fuel emissions, heavy metals like mercury are winding up in the water and building up in our fish. Unfortunately, low-level mercury poisoning from contaminated seafood is a real threat and can lead to devastating effects on health.

Not only that, but some fish have also been so overfished that they are on the brink of collapse, which can have detrimental effects on the ocean ecosystem. In fact, the shift to eating more farmed fish like tilapia is leading to highly inflammatory diets, according to a 2008 study published in the Journal of the American Dietetic Association.

Wake Forest University School of Medicine researchers say tilapia is one of the most widely consumed fish in America. Sustaining high levels of inflammation in the body can worsen symptoms of autoimmune disorders and may be linked to chronic conditions like heart disease, cancer and diabetes.

If you must eat this fish, avoid tilapia from China, where farming practices are particularly worrisome. Although the female cod releases more than a hundred million eggs, only a few are able to survive to adulthood.

In 2014, Oceana, the largest ocean conservation group in the world, conducted an investigation using data from the National Marine Fisheries Service. They found that commercial fishermen in the U.S. throw about 2 billion pounds of “by catch” overboard each year.

According to the report, if you’ve eaten U.S. halibut, there’s a good chance it came from this damaging fishery. Without further protection and enforcement of existing efforts, we may forever lose one of the biggest, most interesting fishes in the world.

Furthermore, harvesting the fish from Chile is also plagued by poor management and by catch problems. Eel Monterey Bay Aquarium’s Seafood Watch places eel on the “Avoid” list on its sushi guide because it’s slow to mature and has been overfished in many parts of the world, bringing some populations to collapse.

In the Delaware River, for instance, eels are an integral part of spreading mussel populations that serve as natural water filters. Aside from the issues with overfishing, eels tend to readily absorb and store harmful chemicals and contaminants such as poly chlorinated biphenyls (PCs) and flame retardants.

They’re also commonly treated with a broad range of antibiotics, in addition to pesticides and disinfectants. In 2009, Italian researchers discovered that 4-hexylresorcinol, a food additive used to prevent discoloration in shrimp that could reduce sperm count in men and increase breast cancer risk in women.

Shrimp farm ponds are also treated with harmful chemicals and pesticides such as malachite green, rote none and organic compounds, all of which can have detrimental effects on health. Plus, an Associated Press investigation uncovered a slavery network in Thailand dedicated to peeling shrimp sold around the world.

In 2007, Thailand alone exported about $1.24 billion to the United States, according to Food and Water Watch. Although Alaskan king crab legs legally can only be called that if they’re harvested from Alaska, widespread mislabeling is the norm.

Generally known as “slime head” within the scientific community, seafood marketers had other ideas for this fish and gave the species a more appetizing name. Since orange roughly don’t reach sexual maturity until at least 20 years old, they are very slow to recovery.

According to Oceana: “The extremely long lifespan and the late age at maturity imply that a decimated population may take a half century or longer before it can recover.” Beyond that, the orange roughly is also known to have higher mercury levels, which can be dangerous if consumed in large amounts.

But apart from that, most shark species, which are slow to mature and don’t have a lot of offspring, are severely depleted. Often referred to as Hon Mauro on sushi menus, this simply means blue fin tuna, which should be avoided at all costs.

A better sushi choice would be fatso/skip jack tuna caught through Pacific troll or pole and line methods only. However, due to its high demand for sushi, fisheries managers are still allowing commercial fishing to target it.

Sadly, blue fin tuna numbers are at just 2.6 percent of historic population levels. Aside from the obvious population collapse and extinction threat, this is also a large predatory fish that harbors higher levels of mercury.

In fact, the mercury in this fish is so high that the Environmental Defense Fund recommends women and children avoid it altogether. That’s certainly the case with king mackerel, as the Food and Drug Administration warns women and children to outright avoid it.

Luckily, Atlantic mackerel is high in omega-3s, low in mercury and is rated a top choice in terms of health and sustainability. In 2015, an investigation found that more than a third of 19 restaurants in Atlanta sold fantasies (also known as “Vietnamese catfish”) as grouper.

In addition to being rich in heart-healthy fats, salmon is a great source of protein, B vitamins, potassium and selenium. Atlantic mackerel This oily fish is also high in health omega-3 fatty acids, along with protein, niacin, selenium and vitamin B12.

Finding safer seafood can be challenging and requires you to consider many factors, including sustainability, nutritional value, mercury levels and the risk of contamination with pollutants, pesticides or harmful chemicals. Finally, when you do eat fish, opt for things like wild-caught Alaskan salmon, Pacific sardines and Atlantic mackerel.

They believe the victim could be trawler man Michael Edwards, 39, who has been missing since falling overboard in the Pacific last weekend. Sea-life expert Malcolm Beveridge of Stirling University in Scotland said a crocodile could have killed the victim first.

“I don’t see these big cod leaping out of the water and hauling in a kangaroo. When workers found the head, they ran to phone police, who at first thought the call was a prank.

YouTube's user Gimbb14 was fishing off the coast Bonita Springs, Florida, when he managed to snag a five-foot-long black tip shark. The grouper fish can grow up to eight feet long and tip the scales at 308 kg, so it’s little surprise this shark could still be considered a light lunch.
