You can definately get them before 110, I dont think any of the pie fish/crabs have a high requirement to get. Try letting your traps sit longer 3-4 cycles of bobs even if you lose more traps. Bait use lasts as long as the trap is out so that allows you get get 3-4 uses per bait use per trap even with some sinking. Try that and you should be pulling them up in no time. Hope that helps and good luck.
