I wouldnt go for more than a couple hours after they are killed. They decompose fast. You can put them on ice(live) with good drainage and they will go dormant, they look dead but don't hang like a wet rag. They will last a day or two like that.
Leaving them in the trap is a good idea as long as they don't figure out how to get out.Crabs are a heck of a lot smarter than a lot of people give them credit
What about cleaned and iced (not cooked) ? How long do you think they'd be ok?
Got my answer for this time. Thanks guys. I cleaned some crab over the weekend. Threw it in the cooler with ice. Its been 24 hours now. I'll cook them within the hour. But, for future trips where I'm out fishing for 5 days plus where I don't have access to freezing, it sounds like leaving them in the trap till the last day or two may be the safest route???
