EN_WIKIPEDIA - Lagocephalus sceleratus. The Lagocephalus sceleratus (Gmelin, 1789), known as the silver-cheeked toadfish, is an extremely poisonous marine bony fish in the family Tetraodontidae (puffer fishes).
Habitat and distribution The species is common in the tropical waters of the Indian and Pacific oceans. It is a recent Lessepsian migrant into the eastern Mediterranean Sea, which it reached through the Suez Canal. It has been caught off the coasts of Israel, the south of Turkey, in Cyprus, the south coasts of mainland Greece, Crete and Rhodes. Recently, in 2013, it has been reported off the waters off Lampedusa Island in the central Mediterranean, and in 2015 off Malta and also in waters near the town of Bečići, Montenegro, on the southeastern Adriatic Sea. The silver-cheeked toadfish lives in open waters on rocky bottoms, from shallow coastal waters down to a 250m depth (in the Red Sea).

UICN 07/08/15 L’initiative MedMIS de l’UICN a permis d’identifier des poissons-globe dans l’Adriatique. Une nouvelle observation d’individus de Lagocephalus sceleratus, connus aussi sous le nom de poisson-globe, espèce envahissante et hautement toxique pour l’homme, a pu être réalisée grâce au plan global MedMIS pour la lutte contre les espèces envahissante s introduites dans les Aires Marines Protégées (AMP) en Méditerranée.
Cette initiative a été développée par l’Union Internationale pour la Conservation de la Nature (UICN). L’aire marine protégée de Karaburun – île de Sazani en Albanie, a été le dernier lieu où l’ont a observé cette espèce. Ceci est une information importante enregistrée par le programme MedMIS, car c’est la première fois que cette espèce a pu ètre observée arrivant dans l’Adriatique par le biais de la Méditerranée,. Jusqu’à maintenant, le poisson-globe n’a été vu que 10 fois dans les AMP méditerranéennes, il a surtout été observé en Turquie où il a été aperçu dans 8 AMP différentes.
De plus, ce poisson peut se montrer agressif dans son environnement. INVAZIVNE VRSTE 16/05/15 New records of the Puffer Fish (Lagocephalus sceleratus) in the Adriatic Sea. The Puffer Fish (Lagocephalus sceleratus).
Source: Wikipedia This week, the Puffer Fish (Lagocephalus sceleratus) was caught in the Croatian part of the Adriatic Sea for the fifth time since 2012. Specimens were caught in Dubrovnik-Neretva County and Šibenik-Knin County. Fish poisoning by consumption of the Puffer Fish is extremely serious because it contains Tetradoxin poison (TTX), one of the strongest marine poisons known today. This toxin affects the nervous system and causes paralysis of the diaphragm and there is no antitoxin available. CAUTION: Do not eat the Puffer Fish! It is also advised not to touch this fish without safety gloves. Although its toxicity is well known, it is still used in the preparation of the traditional Fugu dish in China, India and Taiwan.
The species is native to the tropical Indian and Pacific Ocean, and it entered to Mediterranean Sea through the Suez Canal in 2003 (as a so called Lessepsian species).

PARLEMENT EUROPEEN - Réponse à question E-005157-15 Combating the spread of pufferfish. European legislation (Regulation (EC) No 854/2004) states that poisonous fish of the Tetraodontidae family must not be imported into Europe.
The radical increase in the population of pufferfish (Lagocephalus sceleratus) is alarming. It is affecting the fishing economy and is a threat to biodiversity. The most important risk factor, however, is that this species of fish is highly toxic when eaten, as it contains the paralysing neurotoxin tetrodotoxin. However, biotechnology studies suggest that there may be potentially positive uses of this toxin in medicine and pharmacology. The increasing population of pufferfish needs to be systematically observed (over 1-2 years) and the assistance of professional fishermen is critical.
In view of the extremely negative consequences that an over-population of pufferfish would have in the Mediterranean and as the impact of this species of fish on the food chain and the ecosystem must be researched, will the Commission say: Marine and Freshwater Toxins 28/08/14 Pufferfish Poisoning and Tetrodotoxin. Pufferfish possess a potent neurotoxin, tetrodotoxin (TTX), and have caused human intoxications all over the world, especially in East Asia, where people have a time-honored food culture of eating pufferfish.
TTX is distributed over a wide variety of organisms including flatworms, ribbon worms, mollusks, crustaceans, starfish, fish, and amphibians, and in the East Asian or Southeast Asian countries, TTX poisonings due to marine snails, horseshoe crabs, and gobies have also occasionally occurred, suggesting the possibility of further geographic expansion and/or diversification of TTX-bearing organisms caused by a change in the marine environment.

EUROSURVEILLANCE 15/01/15 Detection of the pufferfish toxin tetrodotoxin in European bivalves, England, 2013 to 2014.
We report the first detection of tetrodotoxins (TTX) in European bivalve shellfish.
We demonstrate that TTX is present within the temperate waters of the United Kingdom, along the English Channel, and can accumulate in filter-feeding molluscs. The toxin is heat-stable and thus it cannot be eliminated during cooking. While quantified concentrations were low in comparison to published minimum lethal doses for humans, the results demonstrate that the risk to shellfish consumers should not be discarded. Background Tetrodotoxin (TTX) is the causative agent responsible for pufferfish/fugu poisoning, a fatal marine poisoning found predominantly in tropical regions. It is found mainly in the organs of fish from the Tetraodontidae family, as well as other marine species such as the blue-ringed octopus and gastropods .

Case reports in critical care 01/2012 Severe Tetrodotoxin Poisoning after Consumption of Lagocephalus sceleratus (Pufferfish, Fugu) Fished in Mediterranean Sea, Treated with Cholinesterase Inhibitor. Abstract Lagocephalus sceleratus , or better known as the pufferfish, or fugu, is widespread in Asia and Indo-Pacific regions.
It is a poisonous fish containing tetrodotoxin (TTX) which is a potent neurotoxin. In the Far East, fugu is considered a delicate dish, especially in Japan where it is prepared by experts. Nevertheless, poisoning from Lagocephalus sceleratus is not a rare event. Recent data from Japan indicate an incidence of 45 patients per year and a mortality rate of 11%.
