I've been using a couple of designs the last 2 nights and there is something to be said about how hard a trap full of craws is on non-target fish. Cloverleaf sure catches craws but any fish that gets in is toast. I lose several 4-6" YP every night when they get into the cloverleaf. I've got to try something different although the std funnel traps do catch craws just not many at a time.
The issue is trying to get the largest lobster-like craws, they are big enough they can't get "in" a std trap. This calls for some design work so am trying to make something work.
23.5lbs of craws removed in 2 nights, 2 traps. smaller than about 3" going back but that's only been about 7lbs worth.
