Abstract
Burrowing crayfish are typically sampled by excavation, which results in habitat destruction. Several less destructive trapping methods have been devised, though their results have been inconsistent in our experience. To conduct studies of growth and longevity, a more efficient method was needed to sample burrowing crayfish while leaving their burrows intact. We describe a new trap design based on a reversed pitfall trap. This trap was tested using a population of burrowing crayfish, Cambarus Lacunicambarus diogenes (Devil Crayfish), in Alabama. The weekly trapping success rate (n = 18 traps) over a 4-week period ranged from 6% to 33%, with an average success rate of 17%. We feel that the implementation of our design will enhance studies requiring nondestructive sampling.
