BACKGROUND Poorly regulated international trade in ornamental fishes poses risks to both biodiversity and economic activity via invasive alien species and exotic pathogens. Border security officials need robust tools to confirm identifications, often requiring hard-to-obtain taxonomic literature and expertise. DNA barcoding offers a potentially attractive tool for quarantine inspection, but has...

Heavy metals are known to cause deleterious effects on human health through food chain. Human health risks were evaluated from consumption of heavy metal contaminated fish from Buriganga River in Bangladesh. Whole body of five fish species (Puntius ticto, Puntius sophore, Puntius chola, Labeo rohita and Glossogobius giuris) were analyzed which contained various concentrations of Cd, As, Pb, Cr,...

Puntius denisonii is popularly known as Miss Kerala in India or Denison barb Red line torpedo the global ornamental fish trade. The species endemic to fast-flowing rivers and streams of Western Ghats India. was not very popular earlier aquatic trade but has been great demand aquarium since it exhibited at AQARAMA 1997 Singapore ranked third under new category. export from started 1996–1997, whi...

Metacercariae were recovered from freshwater fish taken from a stream in Lum Cha Muak, Nakhon Ratchasima Province, northeast Thailand during the year 2000. Seventy-nine cyprinoid fish comprising 3 species (52 Puntius leiacanthus, 22 Cyclocheilichthys armatus, and 5 Hampla dispar) were collected. The prevalence of infection with metacercariae was 51.9%. Only two genera of metacercariae were foun...

The intensity of infection of trematode metacercariae was determined in five species of cyprinoid fish collected from Mae Ngud reservoir, Chiang Mai Province. These species were Thynnichthys thynnoides, Puntioplites proctozysron, Hampala macrolepidota, Puntius leiacanthus and Puntius gonionotus. T. thynnoides contained the highest number (83.0%) of metacercariae, whereas P. gonionotus had the f...

In the present reprobiological study on Puntius filamentosus the spawning months of November and April coincided with North-East Monsoon (November) and South-West Monsoon (April) in India. The gross morphology of P. filamentosus showed 6 ovarian stages. The histological appearance of the ovaries showed ten stages (oogonia to atretic oocytes). The testes of Puntius filamentosus showed five morph...

The tropical Asian cyprinid genus Puntius is a major part of the ichthyofauna in Southeast Asia. Systematic status of the genus Puntius among Cyprinidae, the most prominent freshwater fish all over the world, remain to be substantiated. The molecular phylogenetic analyses derived from Recombination activating genesequences (RAG2) for 35 representative samples of Malaysian Puntius and their alli...
