Recreational Fishing Causes Cape Cod Salt Marsh Die-off
June 11, 2012
As recreational fishing activity has reduced predators in many of Cape Cod's salt marsh ecosystems, Sesarma crabs have feasted on grasses, causing dramatic die-offs of the marshes, according to a new study. The researchers assessed the "trophic cascade" in several experiments that also ruled out alternative explanations for the problem.
