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

4. Prepared or preserved mackerel ( Scomber spp. ), whole or in pieces, but not minced, frozen.

5. On above parameters, the utilization situation is simulated by dynamic synthetic model, and the result show that the stock of Scomber japonicus has been severely overfished.

6. The processing technology of grilled fish tidbit by Mackrel ( Scomber japonicus ) was studied.
