First record of the silver-cheeked toad fish Lagocephalus scleratus (Gmelin, 1789) (Actinopterygii: Tetraodontidae) from Chennai coastal waters, Southeast India

The silver-cheeked toad fish, Lagocephalus scleratus, was recorded for the first time on 25 September 2014. Two specimens of this fish species were collected from the by-catch landed by a commercial deep-sea trawler at Kasimedu Fishing Harbour, Chennai coast, Southeast India. The morphometric and meristic characters of the recorded specimens are described and discussed. The specimen was compared with earlier reports.

Evaluation of Helically Coiled and Knitted Open Tubular Reactors for the Efficient Post-Column Determination of Tetrodotoxin by High-Performance Liquid Chromatography

ABSTRACTA postcolumn fluorescence reaction system for the high-performance liquid chromatographic (HPLC) determination of tetrodotoxin in the silver-cheeked toadfish Lagocephalus sceleratus is discussed theoretically and investigated experimentally. Ion-pair chromatography with volatile ammonium perfluoroheptanoate was used for the separation of tetrodotoxin and 4,9-anhydrotetrodotoxin. The postcolumn reaction was based on the tetrodotoxin conversion to a quinazoline fluorescent compound under strong alkaline conditions. All postcolumn parameters were optimized that affected the sensitivity, dispersion, and stability. Helically coiled and knitted open tubular reactors composed of polyetheretherketone were constructed and characterized in detail. The performance of these reactors was evaluated on the basis of sensitivity and dispersion. Their optimal design is reported. The knitted reactors were more efficient than the relevant helically coiled reactors when higher reaction times are required. A 1500-µL polyetheretherketone knitted coil with 0.010″ internal diameter was optimum exhibiting higher pressure tolerances than Teflon coils. The HPLC postcolumn reaction method was evaluated in terms of linearity, sensitivity, accuracy, precision, and ruggedness. The linear dynamic ranges for tetrodotoxin and 4,9-anhydrotetrodotoxin were 40–3000 and 80–3000 ppb, respectively. The limits of detection and quantification were 12 and 41 ppb, respectively, for tetrodotoxin and 26 and 85 ppb, respectively, for 4,9-anhydrotetrodotoxin. The accuracy was evaluated by recovery measurements and the values for tetrodotoxin were between 90.7 and 93.6%. The use of a volatile perfuorocarboxylic acid as an ion-pair reagent allows confirmation of analytes in sample matrix by liquid chromatography tandem mass spectrometry using identical mobile phase conditions.

First record of an invasive Lessepsian migrant, Lagocephalus sceleratus (Actinopterygii: Tetraodontiformes: Tetraodontidae), in the Sea of Marmara

One specimen of the silver-cheeked toadfish, Lagocephalus sceleratus (Gmelin, 1789), was obtained for first time from the Sea of Marmara, off Gelibolu, by trammel net in October 2008. The morphological features of this species were examined. The presently reported finding also represents the second documented occurrence of a puffer fish in the Sea of Marmara.

First record of the silver-cheeked toadfish Lagocephalus sceleratus (Gmelin, 1789) from Malta

The occurrence of the silver-cheeked toadfish, Lagocephalus sceleratus, is reported for the first time from Maltese waters. The specimen was caught at a depth of 15 m in a sparse sea grass Posidonia oceanica meadow. The need for a public information campaign on the danger to human health posed by the species, and to develop an early warning system of its spread, is discussed.

Range expansion of an invasive pufferfish, Lagocephalus sceleratus (Actinopterygii: Tetraodontiformes: Tetraodontidae), to the south-western Mediterranean

Three specimens of silver-cheeked toadfish, Lagocephalus sceleratus (Gmelin, 1789), were caught on eastern coasts of Algeria during the winter of 2013–2014. This is the first record of this invasive species from Algeria, providing further evidence of its occurrence along north-African coasts and confirming its entry into the Western basin of the Mediterranean. The human-health implications of this toxic fish in this region are discussed.

Lagocephalus sceleratus (Gmelin, 1789) expands through the African coasts towards the Western Mediterranean Sea: A call for awareness

The silver-cheeked toadfish Lagocephalus sceleratus is one of the most recent invaders in the Mediterranean Sea and a serious risk for public health. In June 2011, an awareness campaign to disseminate information related with this toxic species was launched by the Tunisian Ministry of Agriculture. Whilst providing a step toward the development of an appropriate early warning system, this case highlights a remarkable geographical extension of L. sceleratus along the entire Tunisian shoreline (from the island of Djerba to the region of Tabarka). We illustrate how the first step in the process of effectively managing the risks posed by an invasive species is to engage and communicate with the public.

Additional records of Lobotes surinamensis, Caranx crysos, Enchelycore anatina, and Lagocephalus sceleratus (Actinopterygii) in the Adriatic Sea

Additional records of four fish species are reported from the Adriatic Sea are reported: Atlantic tripletail, Lobotes surinamensis (Bloch, 1790) (Perciformes: Lobotidae); blue runner, Caranx crysos (Mitchill, 1815) (Perciformes: Carangidae); fangtooth moray, Enchelycore anatina (Lowe, 1838) (Anguilliformes: Muraenidae); and silver-cheeked toadfish, Lagocephalus sceleratus (Gmelin, 1789) (Tetraodontiformes: Tetraodontidae). More evidence is needed to indicate establishment of populations of these species in the Adriatic Sea. Lessepsian migrant Lagocephalus sceleratus is the third Lessepsian fish species from the Adriatic Sea with more than one record.
