摘要：

In a field experiment in a subtidal habitat in W Scotland, cages covering 1 m2 maintained crab densities from 0-8 crabs m-2 (0-32 times natural densities) for 24 days. There was little evidence that predation by Liocarcinus had any significant effect on the abundance of benthic species. Multivariate analysis suggested some effects of caging, possibly due to the exclusion of other predators in addition to crabs in the case of infauna. -from Authors
