Sublethal adverse effects may result from exposure of aquatic organisms to insecticides at environmentally relevant concentrations. Fingerlings of the common carp (Cyprinus carpio, Linnaeus, 1758), grass carp (Ctenopharyngodon idella, Valenciennes, 1844), and bighead carp (Aristichthys nobilis, Richardson, 1845) were exposed to diafuran, an insecticide widely used during rice cultivation in Southern Brazil. The aim of this study was to verify the relationship between the lethal concentration (LC50) of diafuran and the acetylcholinesterase (AChE) activity in brain and muscle tissues of these species as a possible early biomarker of exposure to this insecticide. LC50 was determined for fish exposed to diafuran concentrations during 96 h (short term): common carp: control, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mg L-1; grass carp: control, 1.0, 2.0, 3.0 and 3.5 mg L-1 and, bighead carp: control, 0.5, 1.0, 1.5, 2.0, 3.0 and 4.0 mg L-1, as well as the determination of AChE at concentrations near LC50 for these species. LC50 values (nominal concentrations) were 1.81 mg L-1 for the common carp, 2.71 mg L-1 for the grass carp and, 2.37 mg L-1 for the bighead carp. All carps exposed to diafuran were lethargic (lower concentrations) or immobile. Diafuran inhibited the acetylcholinesterase activity in brain (~38%) and muscle (~50%) of all species. Muscle of bighead carp under control treatment showed higher specific AChE activity than brain (14.44 against 5.94 µmol min-1 g protein-1, respectively). Concentrations of diafuran used for rice cropping may affect Cyprinus carpio, Ctenopharyngodon idella and Aristichthys nobilis behaviors and the AChE activities in brain and muscle of these species may be an early biomarker of toxicity of this insecticide.

Abstract Background Interferon (IFN) regulatory factors (IRFs), as transcriptional regulatory factors, play important roles in regulating the expression of type I IFN and IFN- stimulated genes (ISGs) in innate immune responses. In addition, they participate in cell growth and development and regulate oncogenesis. Results In the present study, the cDNA sequence of IRF10 in common carp (Cyprinus carpio L.) was characterized (abbreviation, CcIRF10). The predicted protein sequence of CcIRF10 shared 52.7–89.2% identity with other teleost IRF10s and contained a DNA-binding domain (DBD), a nuclear localization signal (NLS) and an IRF-associated domain (IAD). Phylogenetic analysis showed that CcIRF10 had the closest relationship with IRF10 of Ctenopharyngodon idella. CcIRF10 transcripts were detectable in all examined tissues, with the highest expression in the gonad and the lowest expression in the head kidney. CcIRF10 expression was upregulated in the spleen, head kidney, foregut and hindgut upon polyinosinic:polycytidylic acid (poly I:C) and Aeromonas hydrophila stimulation and induced by poly I:C, lipopolysaccharide (LPS) and peptidoglycan (PGN) in peripheral blood leucocytes (PBLs) and head kidney leukocytes (HKLs) of C. carpio. In addition, overexpression of CcIRF10 was able to decrease the expression of the IFN and IFN-stimulated genes PKR and ISG15. Conclusions These results indicate that CcIRF10 participates in antiviral and antibacterial immunity and negatively regulates the IFN response, which provides new insights into the IFN system of C. carpio.

Preliminary Study

The classical method of aquaculture in Iraq employed Cyprinus carpio L. (Common carp) as monoculture or as predominat species togather with grass carp and silver carp. In the present study monoculture of grass carp was performed. Three - hundreds fingerlings of grass carp of 1.5 g weight were cultured in about 600 m2 eartheen pond from 20th of June till 9th of November, 1997. For the first two months of the experiment, no additional feed was added to what had been available in the pond. For the rest of the culture period, 1773 kg of five species of plants were utilized. They were included 91 kg of Phargmites australis, 972 kg of Paspalim sp., 423 kg of Medicago sativa, 171 kg of Ceratophyllum demersum and 116 kg of Paspalum Paspaloides. In addition to that a total of 150 kg of manure was used as a fertilizer in three occasions. At the end of the experiment the average weight of the fishes was 498 gm ranged from 370 gm to 980 gm. Further study was commence where 300 fingerlings of grass carp weighting 34 gm as an average were cultured together with 50 fingerlings of silver carp (average weight 92 gm). The experiment January 1998. For the first two months of experiment the fishes didn't consume began in additional food probably due to the low temperature of water during this period.

The article provides calculations and recommendations for fisheries development and improvement of fish productivity of reservoirs in the Kuban basin. The taxonomic composition of water biological resources has been studied and the natural bio-production potential of some reservoirs in the South of Russia has been determined. It is proposed for the purpose of pastoral aquaculture to produce directed formation of the ichthyofauna of reservoirs by yearlings Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Ctenopharyngodon idella, and as anaddition Cyprinus carpio, Mylopharyngodon piceus, Liza haematocheila with an individual mass not less than 25-30 g, which will allow rational use of forage resources of aquatic ecosystems.
