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...
Hematological changes of silver carp (hypophthalmichthys molitrix) in response to Diazinon pesticide
Diazinon is widely consumed for plague control in the agricultural farms and in domestic and aquaculture aspects. The present research purposed to evaluate the effect of half-lethal concentration (LC50) of diazinon on some biochemical and hematological parameters of silver carp, hypophthalmichthys molitrix, after 0, 24, 48 and 96 h. The results showed that the values of leukocytes (WBC), haemat...
background: the present study was carried out to track and calculate biomagnification factor (bmf) of total mercury (t-hg) between two different trophic levels (i.e., plankton and a planktivorous fish) in a fresh water grazing food chain. methods: experimental organisms were planktonic biomass and silver carp (hypophthalmichthys molitrix) as a planktivorous fish. silver carp samples were obtain...
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...
Cystatins are proteins, which inhibit cysteine proteases, such as papain. In this study, the 336-bp cystatin C gene (family II, HmCysC) of silver carp (Hypophthalmichthys molitrix) was cloned and expressed in Escherichia coli BL21 (DE3). HmCysC encodes mature peptide (HmCystatin C), with 111 amino acids. A typical QXXXG motif found HmCystatin it formed a cluster Cyprinus carpio Danio rerio phyl...
Bigheaded carps (bighead carp, Hypophthalmichthys molitrix, and silver nobilis) their hybrids play an important ecological economic role in original habitat, while introduced stocks may pose serious risks. To address questions about the persistence invasiveness of these fish, we need to better understand population structures. The genetic structures bigheaded carp populations inhabiting Lake Ba...
This paper describes seasonal changes of microcystin-LR (MC-LR) and its glutathione (MC-LR-GSH) and cysteine conjugates (MC-LR-Cys) in three aquatic animals--snail (Bellamya aeruginosa), shrimp (Macrobrachium nipponensis) and silver carp (Hypophthalmichthys molitrix) collected from Lake Taihu, China. MC-LR, MC-LR-GSH, and MC-LR-Cys were determined by liquid chromatography electrospray ionizatio...
The present study was conducted to reveal a histological analysis on the gills of Labeo rohita and Hypophthalmichthys molitrix specimens were observed to reveal the histo-pathological characteristics of the gills of these freshwater carps. The histological examination of the gills of Labeo rohita revealed the proliferation of bronchial tips, shortening and fusion of secondary gill lamellae, des...
