Pack and freeze herring when you buy it, take a small bag each time and make sure the herring you use for fishing is fresh. Fresh herring is very tempting to mackerel.
You can also separate a box of stag into several bags. So one box of stag can be used several times with completely fresh. Put the newly purchased stag in the fresh part of the refrigerator for 5 hours to defrost it. Then separate it.
