The Resilient Blue Crab

The following op-ed appeared on Friday in the Washington Post.

It's clearly been a poor year for Chesapeake Bay blue crab harvests. Average catches just three years ago were as much as twice as what they are now.

That is where Angus Phillips ["It's now or never for blue crabs," Sunday Opinion, July 27] and I agree. Where we disagree is what to do about it. Phillips called for a moratorium on crabbing. The Chesapeake Bay Foundation (CBF) does not. Like many, we believe in managing fisheries through science, not quick-fix schemes. As my eighth-grade history teacher used to say, "Beware of simple answers to complex problems."

While a moratorium may be tempting in its simplicity, the CBF and most scientists believe that limits on the harvesting of female crabs are biologically appropriate for such a resilient species (which is far different from the striped bass, for which the CBF was a moratorium advocate). This approach will also have the added benefit of maintaining jobs and avoiding the economic devastation to communities like Smith and Tangier islands.

Blue crab reproductive success from year to year depends on many factors. Weather is one. Last winter's cold weather killed an estimated 28 percent of the bay's crabs. Pollution also can cause habitat loss. Bay grasses -- great places for young crabs to hide from predators -- are currently at only 20 percent of historic levels. The bay's dead zones kill the creatures that crabs rely on for food.

We believe that only a comprehensive crab management plan that addresses pollution, habitat and harvest will provide for a long-term sustainable fishery.

While there is plenty of reason for concern, there is also a bright note this crabbing season: Early results from Maryland and Virginia show an encouraging number of young crabs.

Phillips rhetorically asked whether the CBF is aware of the situation. Of course we are. The CBF's scientists have been in communication with the Maryland, Potomac and Virginia regulatory agencies responsible for blue crab management. Our senior fisheries scientist also is a member of the Sustainable Fisheries Goal Implementation Team, which oversees blue crab management baywide.

Phillips said he could not find one word about the issue on our Web site. I invite him to look again. A search of our Web site turned up more than 1,400 mentions of crabs -- their importance, value and plight. In May, we published "Blue News," a blog posted soon after the annual crab survey results raised concerns about the population. It can be found at www.cbf.org/bluenews.

Finally, Phillips stated that the CBF was raising money for a new wing at our Annapolis Environmental Center, the world's first LEED platinum building. We are not. He also called it a palace. That is an odd description for a building that dramatically cuts energy and water use, reduces human pollution through zero-discharge composting toilets and is built inside and out with sustainable materials.
