In this work, peptides were extracted from Silver carp (SC) scales via protease hydrolysis and separated using two membranes (M1 M2). The results revealed that the water: SC scale ratios of 50.6 mL/g, alkaline 1 (AP1) dose 2313.6 U/mL, pH 8.14 optimal conditions, peptide yield reached 88.77 ± 0.32%. conditions separation clarified: operating pressure M1 (M2) was 0.25 (0.4) MPa, liquid temperatu...

Leptin is an important hormone for the regulation of food intake, energy expenditure and reproduction in mammals, but information regarding its role in teleosts remains scant. In the present study, the gene structures of grass carp (Ctenopharyngodon idellus) and silver carp (Hypophthalmichthys molitrix) leptins were characterized. Recombinant grass carp leptin (rgc-LEP) was expressed in Escheri...

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 obt...
