Analysis of the Chromosome Karyotype of Catfish(Silurus asotus) in Dongting Lake

Molecular Cloning and Prokaryotic Expression of Growth Hormone in Silurus asotus;

Observation of the Entrance Process of Hybrid Silurus asotus Sperm into Eggs by Scanning Electron Microscope;

Study on General Characteristics of Catfish Surface Mucus;

Study on processing technique of enzyme hydrolysis of catfish collagen peptide with immunite activity;

By a series of tests for the fertilized times,hydrostatic pressure and treated times of catfish eggs, the results indicated that the best condition of inducement triploid is 4-5 min after fertilization, and that the eggs were treated for 3min at 600~640kg/cm2 of hydrostatic pressure.
