Both raw and cooked should last quite a while.
Went for a Surf-cast at Blue Gum tonight, arrived 7:30 and the action was almost immediate, all up landed 4 Rig, 1 Small, 2 Medium and 1 big. Run out of bait elastic around 8:30pm so packed up. Also lost mu pliers, luckily I had two spare pairs at home Weather was nice enough, a few powerful gusts to ruin a otherwise nice evening.
So 6 Rig for the season.
