Many experimental studies have documented the impact of microcystins (MC) on fish based on either intraperitoneal injection, or oral gavaging via the diet, but few experiments were conducted by MC exposure through natural food uptake in lakes. In this study, the phytoplanktivorous silver carp were stocked in a large pen set in Meiliang Bay of Taihu Lake where toxic Microcystis blooms occurred i...

Management of silver carp Hypophthalmichthys molitrix has become a growing concern for multiple state and federal entities. Commercial fishing may have the greatest potential to control silver carp. However, for a management action to be successful, the level of exploitation required to reduce silver carp populations must be quantified. Therefore, silver carp were collected from Midwestern U.S....

The purpose of the study was to determine the microbiological status of 161 samples cooled and frozen fish products collected from retail markets in the Republic of Bulgaria. The highest total viable counts (TVCs) in cooled fish products were established for silver carp (7.30 log cfu/g), Black sea roach (7.28 log cfu/g) and trout (7.11 log cfu/g), followed by common carp (6.81 log cfu/g), vacuu...

This paper proposes a new transformation of arc routing problems into equivalents node routing problems, with emphasis on the transformation of Capacitated Arc Routing Problems (CARP) into Capacitated Vehicle Routing Problems (CVRP). For this last case, an analogue transformation has already been proposed in Pearn et al. [21], where each required CARP arc was mapped onto a triplet of CVRP nodes...

A method for purification of carp serum immunoglobulin (IgM), intended for the production of monoclonal antibodies, was described in the present study. Hybridomas that produce antibodies against IgM heavy chain were selected by ELISA method and Western blotting. Ascitic fluids were prepared and tested by the above mentioned methods, and their typing followed. Monoclonal antibody with the highes...

Carp erythrocytes were fractionated by angle-head centrifugation which yielded fractions with a linear increase in density. Haematological examinations revealed that the heavier red blood cells of carp had greater volumes (MCV), more haemoglobin (MCH) and higher haemoglobin concentrations (MCHC) than light ones. The same experiments with human red cell fractions yielded a decrease in MCV, const...

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities...

Cyprinid herpesvirus 3 (CyHV-3) infects koi and common carp and causes widespread mortalities. While the virus is a significant concern for aquaculture operations in many countries, in Australia the virus may be a useful biocontrol agent for pest carp. However, carp immune responses to CyHV-3, and the molecular mechanisms underpinning resistance, are not well understood. Here we used RNA-Seq on...

BACKGROUND During the inflammatory process, chemokine CXCL8 plays a pivotal role in recruitment of human neutrophilic granulocytes. A diversity of sequences similar to CXCL8 was reported in fish, but their evolutionary relationships and functional homology with their human homolog remain unclear. PRINCIPAL FINDINGS We screened fish genomes to seek for sequences related to CXCL8. A first linea...

Goussia carpelli causes enteritic coccidiosis in juvenile carp. In nature it affects carp fry (1 to 2 mo old) and fish (3 to 4 mo old) which are subjected to environmental stress. Carp treated with corticosteroids or subjected to temperature stress in the laboratory produced higher numbers of oocysts during the primary infection. Resistance to reinfection via the fecal contamination route, howe...
