Thirty-one primers were screened from 78 random primers by RAPD(random amplified polymorphic DNA) technique,and 10 randomly selected samples from each population(including Scomber japonicus from the west of Goto Islands and the west of East China Sea,respectively and S australasicus from the East China Sea) were analyzed.

Based on 19 morphological proportional characters of Scomber japonicus and S.

Chub mackerel (Scomber japonicus) is one of the important pelagic fishery resources in the China\'s coastal waters.

Growth characteristics and rational exploitation of Scomber japonicus in the north of the East China Sea and the nouth of the Yellow Sea;

Bio-economic model and its application of chub mackerel in the East China Sea and Yellow Sea

The chub mackerel filets were degreased by skinning, bleaching with complex salt solution, pressing and bleaching with potherb mustard juice successively.

Preparation of sport beverage with hydrolyzate of macherel protein;

Preparation of low-molecular weight peptide from macherel by enzymatic hydrolysis;

The optimal formula and sterilization condition for preparing oral liquid of low - molecular weight peptide with hydrolyzate of macherel protein were determined.
