Sorry for my slow reply...I got side tracked
Yes, salting pillies is much the same. Just a couple of things to note.
The pillies are thicker than prawns and much firmer flesh, so need more salt. I usually cover the pillies completely...as in fully covered so that about 1 or 2 cm of salt is over them.
Side note...I seem to remember saying this before...25kg bag of "pool salt" at Bunnings is about $8. It is still sea salt just not certified as "food grade"...
The other thing about salting pillies (or any fish) is the guts...Like all animals, the gut are water tight. This means that mirobs will survive in the gut even after salting. Yes, the gut will be dehydrated quite a bit from salting, but there will remain enough moisture for bacteria to take hold.
So the whole pillies from a slab after salting will last 3 or 4 months if kept cool. But, if you take the time to remove the gut, they will last much, much longer.
I really must do that salting pillies topic I promised...But then again, I am pretty lazy
