Tul, i reuse my chovies till a slab sucks them down their throat. After each trip now, i put them back into a plastic container full of rock salt and cover them in salt. Then into freezer when i get home. Obviously if they're falling apart they get chucked. I'd say ive increased the life span of my chovies by 50 percent following this method. The salt cures them. Makes them very tough, but, they soften once in the water. Other people follow other methods. I was taught this process by Spanish fisherman who've done it for centuries. Works for me.
