Perhaps, they were restricted on game/fish gathering? Also, I saw that only one of them (Alan) selected the snare wire: http://www.history.com/shows/alone/cast/alan-kay , but he has mentioned once (in the ep.9) that his loops in the grass never took anything (I'd rather put them on the trees for squirrels and alike).



I think, he was either too lazy, or already exhausted after the rainfalls period to research trails and make enough traps (same with Sam Larson, who made just 4-5 simplistic falling traps, when 20-30 are needed typically). By the way, our beloved LM Multitool was available for pick up as well, but only one guy (Wayne) took it...

Personally, I would be relying solely on the ocean, as the game is definitely looks quite aware of hunters, even squirrels (ep.9s bow hunting attempt) seem extremely cautious. The tide, soil, and abundance of the construction wood - looks perfect for gradually building a massive stationary fish trap, i.e.: http://preparednessadvice.com/uncategorized/how-to-trap-fish/#.VdStbPlVhBc the gill net and basket trap, which were proven to work there, are toys compared to that.

Also, I know for sure, that place must be abundant of edible mushrooms. That would be the first thing to research and prepare for, as soon as they knew the approximate area (they've been told that 2 weeks before the journey).
