Background: Test of pahogenecity of fish pathogens usually done by injection or ingestion of the bacterial samples on the fish. Objective of the current research was to introduce a new method of testing pathogenecity of fish pathogens through an artificial infection system. The targeted method was to observe the pathogenecity in aquarium condition by direct infection of the system water with ba...

As an important freshwater species with economic and ecological benefits, silver carp (Hypophthalmichthys molitrix) exhibits poor tolerance to hypoxia. Glucose transporters (GLUTs) are core membrane proteins that transport glucose tissues regulate essential life activities. Its expression is regulated by HIF-1α cells in hypoxic conditions maintain energy demand through GLUTs inducing enhanced t...

Field studies to detect environmental DNA (eDNA) can be undertaken to infer the presence of a rare or cryptic species in a water body. These studies are implemented by collecting water samples from the water body, processing those samples to isolate genetic material contained in the water sample, and using a laboratory assay to find a species-specific genetic marker within a sample of the genet...

The effect of fennel extract on the quality of silver carp (Hypophthalmicthys molitrix) fillets, and the possible efficacy of liposomal encapsulation in the improvement of its antimicrobial and antioxidant activity during chilled storage (4 + 1°C) of the fillets were examined over a period of 15 days. Silver carp fillets were treated with pure fennel extract (0.3% and 0.5% w/v) and liposomal en...

Based upon morphological characters, Silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis (or Aristichthys nobilis) have been classified into either the same genus or two distinct genera. Consequently, the taxonomic relationship of the two species at the generic level remains equivocal. This issue is addressed by sequencing complete mitochondrial genomes of H. mol...
