Fish is an important source of antimicrobial peptides. This study aimed to identify and screen antibacterial peptides with excellent activity derived from sturgeon spermary (SSPs) analyze their mechanism. Liquid chromatography-mass spectrometry/mass spectrometry methods were used peptide sequences, computational prediction tool molecular docking for virtual screening peptides, finally, candidat...

sperm morphology, biochemistry and physiology were compared between siberian sturgeon Acipenser baerii and sterlet A. ruthenus in the present study. We observed wide morphological variations between spermatozoa of the two species. the average length of the spermatozoon head was 7.01 and 5.14 μm in A. baerii and A. ruthenus, respectively. Significant differences were observed in terms of Na+, k+...
