The genus Gnathostoma contains at least twelve distinctive species. Among these, 6 species, namely G. spinigerum, G. hispidum, G. doloresi, G. vietnamicum, G. malaysiae and G. nipponicum, are found in wild animals in Asia. Related to human gnathostomiasis, G. spinigerum has long been believed as the only causative species. Until the early 1980s, all gnathostomiasis cases found in major endemic ...

Ossifications associated with the gill filaments of members of the Balitoridae and Cobitidae are described for the first time. Although gill-filament ossifications are common in teleosts, similar ossifications were not observed in other members of the order Cypriniformes. Their presence is interpreted as a shared and derived character uniting the families Balitoridae and Cobitidae as a monophyl...

Abstract Risk analyses for invasive species often assume that the characteristics of future invaders will resemble those already successful, but these features may change. Here, we use data from more than 3,500 fish sampling events, sequencing mitochondrial and nuclear genes several traits describing non‐native to describe irruption rapid expansion loaches in Catalonia, north‐east Iberian Penin...

Stream degradation increases with high anthropogenic activity and climate variability, while declines occur in biodiversity. However, few studies have been undertaken on tropical waterways, a major impediment to biodiversity conservation. The present study was conducted 95 relatively pristine small streams Eastern Thailand 10 reasonably uncommon species of balitorid fishes. Measurements were ma...

As a new freshwater aquaculture product, triploid loaches (Misgurnus anguillicaudatus) are characterized by fast growth, high-quality meat, high edibility, resistance to disease, and sterility. In this study, natural tetraploid loach (4n = 100) (?) was crossed with diploid (2n 50) (?), thus creating the hybrid (3n 75). The histological observations of offspring controls at 4 days post-hatching ...

Fish of the superfamily Cobitoidea sensu stricto (namely loaches) exhibit extremely high diversity of color patterns, but so far little is known about their evolutionary mechanism. Melanocortin 1 receptor gene (MC1R) plays an important role during the synthesis of melanin and formation of animal body color patterns. In this study, we amplified and sequenced the partial MC1R gene for 44 loach in...

Lepidocephalus has been assumed to include only two species and confined to peninsular Malaysia and Indonesia. However, based on records and collections reported herein, the genus contains five species and is most common in the Chao Phraya basin of Thailand. Large rivers seem to be the preferred habitat, and difficulty in collecting these rivers may account for the paucity of specimens in colle...
