The selling and importing of puffer fish species and their products was banned in Thailand in 2002, because of possible neurotoxic effects. However, the sale of their flesh is still happening in Thai markets. Standard methods for toxin quantification (HPLC and LC-MS) have significant limitations, therefore a lateral flow, immuno-chromatographic test (TTX-IC) was developed as a tool for rapid detection of toxin. A total of 750 puffer fishes (387 Lagocephalus lunaris(LL), and 363 Lagocephalus spadiceus (LS)) and 100 edible fishes were caught in Thailand from June 2011-February 2012. Screening of TTX from their flesh by TTX-IC revealed that 69 samples (17.8%) of LL possessed TTX at dangerous levels but LS and edible fishes did not. A selected 339 samples were quantified by LC-MS/MS, showing 50 LL possessed TTX at dangerous levels. Comparison of results with LC-MS/MS showed the TTX-IC to have 94.0% sensitivity and 92.4% specificity. The TTX-IC will be a useful tool for TTX screening of a large number of samples, reducing the testing required by LC-MS/MS, thus reducing costs. All positive cases found should be confirmed by standard methods.

Comparative transcriptome analysis identified genes involved in testicular development in Takifugu rubripes.

To identify candidate genes and pathways involved in testicular development in Takifugu rubripes, a comparative transcription analysis was conducted across the various developmental stages of the testis (stages II to V). A total of 9520 differentially expressed genes (DEGs) were identified among the different stages, and they were significantly clustered into six clusters (P < 0.05).

Takifugu bimaculatus, a pufferfish species farmed in Fujian Province, is known for its non-toxic flesh and collagen-rich skin. We identified a novel collagen-derived matrix metalloproteinase 1 (MMP-1) inhibitory peptide, from T. bimaculatus skin with potent anti-photoaging properties.

Tetrodotoxin (TTX) is a neurotoxin that binds to sodium channels and blocks sodium conduction. Importantly, TTX has been increasingly detected in edible aquatic organisms. Because of this and the lack of specific antidotes, TTX poisoning is now a major threat to public health.

The evolutionary conservation of the building plan of the heart suggests this organ is under substantial form-function constraints. Its form varies to such a degree, however, that it questions whether we understand the form-function relations of the heart. A previously published image of the heart of the sunfish (Mola mola, Tetraodontiformes) indicates the presence of an exceptionally simple topology of the chambers.

The fossil puffer fish genus †Archaeotetraodon Tyler & Bannikov, 1994 is unique among the Tetraodontidae in having the upright central spinule of the dermal scale plates bifid rather than singular and undivided. Six species of this genus have previously been described variously from the Oligocene and Miocene of Russia, Italy, Algeria, and Ukraine. Described herein is a seventh species of this genus, †Archaeotetraodon bemisae sp.
