troppo-- you may jest about crays being used for bait - a complete waste of a great feed if you ask me. However a slice of cray tail has been known (by those in the know) to be seriously tempable as bait, snapper love them. In fact the main reason snapper have such might jaws is to crack hard shells such as crays, sea eggs (we call them kina) and hard shells like mussels etc. They also use them to eat live bait- yes big snapper (20lb+) are well known to nail a live bait - sometimes a by catch when targeting kingfish. A well known and recently released snapper fishing DVD in NZ(ITM fishing for snapper) had under water footage of a estimated 30lb+ snapper taking down a 25 - 30cm kawahi (aussie salmon) in 2 gulps, then smoking the fisher into a reef. they don;t get that big for no reason. The footage was amazing and I think I've seen it 20 times and it still makes my mouth water...
