prawn spinner curing question

I read Jammers article on using and rigging prawn spinners and I was interested in giving them a try in the salt near the bottom for winter spring salmon. My question is does anyone who has used these cure them to toughen them up in any way? I can get lots of fresh prawns but I'm thinking they might need to be salted like we do anchovy or herring to make them last longer on the troll.

There are several ways to do it, some more secret than others .  An easy way is to use your favorite salmon egg cure then drain and pack in rock salt.

I use Pro-cure for curing the cooked shrimp you buy at the grocery store in those big platters.  They work great for Steelhead! I use pieces on jigs in the winter and the whole shrimp on SnG set-ups in the summer.  I haven't tried packing them in rocksalt yet.  Definitely give that a shot if I ever run out the little single trip containers I have frozen.

Thanks for the replies--that is exactly what I needed to know. I will pick up some pro-cure and get some ready for fishing over xmas. My brother is getting 200-300 prawns a pull right now so I'll get some from him--and some for the frypan too!

will that work for sand shrimp too? they only live a few days in the fridge.

Short answer.. No

sand shrimp are tough to keep alive.
 I helped a friend build a "keeper" from a Nestle ice cream display freezer he picked up used from Fred Meyer.
 When we got it dialed in....42*-45* F with a costant drip of sea water (changed daily) they did quite well for 2-3 weeks, then they starved to death (my personal guess)
