the purpose of this project is the investigation of lhrha2 integrated effect with carp pituitary extract (cpe) in three stages injection on sexual indexes (fecundity, fertilization, hatch and larval survival) in artificial propagation of barbusxanthopterus. 20 fish were divided in to 4 treatment and injected interpritoneal as follows 4mgkg-1b.w.of cpe as positive control, 4 µg/kg +4 mgkg-1b.w. ...

Plant extracts have a long history to be used in folk medicine. Cassia alata extracts are known to exert antibacterial activity but details on compounds and mechanism of action remain poorly explored. We purified and concentrated the aqueous leaf extract of C. alata by reverse phase-solid phase extraction and screened the resulting CaRP extract for antimicrobial activity. CaRP extract exhibited...

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...

In teleostean fishes the hypothalamic-pituitary-thyroid axis (HPT axis) and the hypothalamic-pituitary-interrenal axis (HPI axis) regulate the release of thyroid hormones (THs) and cortisol respectively. Since many actions of both hormones are involved in the regulation of metabolic processes, communication between both signal pathways can be anticipated. In this study, we describe central and ...

The purpose of this project is the investigation of LHRHa2 integrated effect with carp pituitary extract (CPE) in three stages injection on sexual indexes (fecundity, fertilization, hatch and larval survival) in artificial propagation of Barbusxanthopterus. 20 fish were divided in to 4 treatment and injected interpritoneal as follows 4mgkg-1b.w.of CPE as positive control, 4 µg/kg +4 mgkg-1b.w. ...

In this study, five carp pituitary glands were collected and dispersed enzymatically and mechanically.Then, the cells were cultivated as monolayer in MEM (minimum essential medium Eagle). The culture mediawere collected after 72 h and frozen at -20°C. Carp ovarian follicles also were separated mechanically andincubated in BSS (basic salt solution) Cortland medium in 24-well microplates for 48 h...

Here we show the cloning and characterization of a novel homolog of prepro C-RFa cDNA from Cyprinus carpio. The deduced preprohormone precursor of 115 amino acids leads to a mature bioactive peptide of 20 amino acids with identical sequence to other teleost C-RFa. Modeling of the mature C-RFa peptide highlighted signifi cant similarity to homologous human PrRP20, specifi cally the conserved amp...

The out-of season induced spawning of the Cyprinus carpio was done during period October 2009 to February 2010 (Autumn and Winter), in hatchery Marin Science Center. brooders average weight 1.700-4.000 kg for females 1.500-1.800 males. were acclimated on 22 °C, a 10 days. photoperiod 12-14 hour/day. results showed that this regime only one female 3males had positive reaction pituitary gland hor...

In December 2022, 10 females and 2 males of common carp (Common carp) from ponds (water temperature 10°C) were placed in RAS pools (control group) an open pond Uzbeki-stan. January, the water was increased by 1°C two days for weeks. Since January 20, 22-24°C The fish had weigh 2950 – 3980 (average 3235) g. From February 3th, 4 injected with pituitary gland according to routine methods ripe eggs...
