Bait is rather expensive these days and can take up a decent portion of your fishing trip budget. Pilchards are an extremely popular bait and are nearly always acquired in a frozen state. IQF (individual quick frozen) baits are handy, as you can just defrost the pilchards a few at a time as required, which helps to minimise waste.
Block pilchards require that you defrost the entire amount (generally around 2kg) so that you can use them. If you don’t use all of them soon after defrosting, the remainder are only good for berley. They will be mushy and commonly break apart after refreezing and then defrosting again. One way to toughen these baits and render them useful for future trips is to salt them down.
Apart from making pilchards tougher, salting can also make them last a lot longer without freezing, or even refrigeration. This is ideal when going on extended trips either offshore, or beach fishing where refrigeration access can be limited. The process of salting sucks a lot of the fluids out of the fish and also draws moisture out of the bacteria in the flesh, killing it or making it go dormant.
This means the flesh won’t decay or smell badly. Salting fish is extremely easy and relatively quick. If you have the salt at hand, it only takes a few minutes to do after returning home from a day’s fishing. There are several ways to salt pilchards and other fish. These are all relatively similar.
The longer you salt the fish, the firmer it will be and longer it will last. Salted fish can even be stored without refrigeration. The pilchards or other fish can simply be put in a large sealed container or bucket with plenty of salt and a few taken out as required. To stop the long-term salted pilchards going too hard, adding some borax (sodium borate, sodium tetraborate or disodium tetraborate) to your salt (about one cup to each 1-1.5kg) will help to keep pilchards fairly soft and pliable.
It is advised not to use iodised (table) salt to preserve your pilchards, as it is believed that the iodine repels fish. Iodised salt is also a little too expensive to use for this process anyway. Anglers commonly use coarse salt or swimming pool salt. A 10kg bag of pool salt can be purchased for around $5 from Woolworths or a 25kg bag of slightly coarser swimming pool salt is around $8 at Bunnings.
Basically, if you want salted pilchards that last a long time and don’t require any form of cooling, you can just put them in a sealed bucket with loads of salt and leave them. However, unless you add some borax, they can become a little too firm to be pinned on the hooks and used effectively for species like tailor. Lighter (shorter term) salting will firm pilchards enough to make them great baits, but they’ll probably need to be kept cool to last for longer periods.
I often salt and freeze leftover pilchards for the long term. Keeping them in the fridge or esky would be sufficient to preserve them for several weeks until your next trip. If heading away to somewhere with limited refrigeration, you may want to salt some pilchards a week or two before your trip.Reads: 7703
