Crab comeback?Policy

Update: Rep. Rob Wittman with an exclusive statement to Bearing Drift:

“I am cautiously optimistic to hear that the blue crab population in the Chesapeake Bay is coming back. We need to ensure the health of the blue crab population, while at the same time keeping in mind the effects the harvest restrictions have on our watermen. In addition, any long-term recovery of the blue crab ultimately depends on the water quality of the Bay, and that is why I have introduced the Chesapeake Bay Accountability and Recovery Act. This bill would enhance the coordination, flexibility, and efficiency of restoration efforts; and it would enact the same management and budgeting tools that were used to successfully restore the Great Lakes and the Everglades. By improving the water quality of the Bay, we will help not only the blue crab population, but also the oyster and other shellfish vital to Virginia’s environment, culture, history, and economy.”

Today, Gov. Tim Kaine and Maryland Governor Martin O’Malley announced the Chesapeake Bay’s adult population of blue crabs has nearly doubled since last year from 280 million to over 400 million, according to the Virginia Institute of Marine Science (VIMS) and the Maryland Department of Natural Resources (DNR).

“This is terrific news and a great first step, but this does not mean the problem is solved,’’ Governor Kaine said. “This scientific survey clearly shows we are on the right path but we need to continue our conservation efforts to rebuild this environmentally and economically vital species. I want to thank our crab industry for their support and endurance through these difficult times.”

The increase in abundance is primarily due to a striking increase in the number of adult female crabs, nearly double last year’s estimate. Coupled with a 50 percent increase in abundance of adult males, overall adult abundance in 2008-2009 is estimated to be approximately 230 million crabs — slightly over the interim target level of 200 million set by the Chesapeake Bay Stock Assessment Committee in early 2008.

Despite the adult population increase, the abundance of young-of-the-year crabs (less than two inches across the carapace) did not change measurably from last year, and remains below the 18-year survey average. These crabs will become vulnerable to the fisheries late in the 2009 season and represent the 2010 spawning potential.

Last spring, in response to scientific data that showed the Bay-wide population of blue crabs had plunged 70 percent since 1993, the two Governors agreed to work collaboratively on a Bay-wide effort to rebuild the species by reducing the harvest of the spawning stock of female blue crabs by 34 percent in 2008.

At that time, scientists from both states deemed conservation measures necessary as blue crabs suffered near historic lows in spawning stock. Despite the states’ shared harvest target of 46 percent, in place since 2001, the combination of low abundance of crabs and continuing high fishing pressure led to more than 60 percent of the Bay’s crab population being harvested in 2007.

Overall, the survey indicates that the 2008 coordinated management actions implemented by the State of Maryland, the Commonwealth of Virginia, and the Potomac River Fisheries Commission, were collectively effective at increasing the abundance of spawning–age females, a major goal of the 2008 conservation measures. These adult females will spawn this summer, and the resulting young crabs will be measured as young-of-the-year during the 2009-2010 survey. It is expected that the large number of mature female crabs conserved last year will significantly increase the chances of a strong spawn in 2009.

“The sharp increase in crab abundance was not a random event, nor was it due to improved environmental conditions. It was clearly due to the recent management actions,” said Dr. Rom Lipcius who directs the VIMS component of the dredge survey. “Now, we have to ensure that these females survive to spawn this summer, and that their offspring produce a healthy spawning stock in coming years.”

Based upon winter dredge survey results, Maryland and Virginia may allow for a slight increase in the harvest of female crabs, while still focusing on the shared goal of restoring the fishery and ensuring that no more than 46 percent of the available crabs are removed in any year. The details of any changes to catch limits and or closing dates will be developed in coordination among the management jurisdictions and in consultation with stakeholders. Changes are anticipated by the end of May.

The Bay jurisdictions will be working through 2009 to establish long-term management approaches that will maintain focus on annual removal rates, improve the efficiency and predictability of blue crab management (i.e. develop harvest allocation by jurisdiction) and increase the level of certainty in our management actions (i.e. addressing latent effort).

In September 2008, Maryland and Virginia were each awarded $10 million in federal blue crab disaster funds from NOAA‘s National Marine Fisheries Service, in response to a request from Governors O’Malley and Kaine, and advocacy by the Maryland and Virginia Congressional Delegations under the leadership of Senators Barbara Mikulski and Jim Webb. Each State also expects to receive $5 million in additional federal disaster funding as a result of recent federal budget action.

In addition to crab management measures to achieve harvest reductions, Virginia has undertaken additional bold regulatory and funding initiatives to significantly reduce pollutant loads from point sources, agricultural lands and urban stormwater, which are negatively impacting the Bay’s crab population.

The Bay-wide blue crab winter dredge survey is a cooperative effort between DNR and VIMS, and is the primary survey used to assess the condition of the Chesapeake Bay blue crab population. Since 1990, the survey has employed crab dredges to sample blue crabs at 1,500 sites throughout the Chesapeake Bay from December through March. By sampling during winter when blue crabs are buried in the mud and stationary, scientists can develop, with good precision, estimates of the number of crabs present in the Bay.

Estimates of abundance are developed separately for young of the year crabs, mature female crabs, and adult male crabs. Together, these groups of crabs will support the 2009 fishery and produce the next generation of crabs. In May, the NOAA Chesapeake Bay Stock Assessment Committee (CBSAC) will conduct a complete examination of the blue crab data including dredge survey results and 2008 harvest information. The results of this analysis will be presented in the 2009 Blue Crab Advisory Report to be released in late summer of 2009.

“It is very gratifying to see success in our efforts to rebuild the crab population, and some financial help for our hard-hit crabbers,” said Governor Kaine. “The crab population is stabilizing but we need to maintain discipline and stay the course. We are now in a position for the next phase of the recovery. We dare not backslide.”

    Not bad, considering the Chesapeake Bay Foundation says things aren’t getting any better. Crabs seem to think otherwise — or is there more to it than this?

    I always knew that it would be the democrats that would cause a resurgence of crabs.

    Seriously though, This surprises me, Given the sorry quality of the water in rivers like the Shenandoah, Bullpasture, Bull Run which have suffered some bad fish kills as of late.

    The watermen predicted in the fall of 2007 that the abundance of crabs was going to increase. In the spring of 2008 the watermen saw more evidence of this increase however Kaine grandstands and scapegoats the watermen and makes them reduce the effort they can put on the fishery by 37%.
    It doesn’t take a rocket scientist to figure out that if you don’t take the crabs out of the water then there will be more in the water.
    There would have been without the reduction in effort. In North Carolina the crabbers had a 50% increase. in 2007 their catch was 20 million pounds and in 2008 their catch was 31 million pounds. Did Kaine and VMRC orchestrate this too?
    Hell no. Kaine puts the Virginia crabber out of work and allows the North Carolina crabber to take the Virginia crabber’s market.
    Hey! It makes good press and by scapegoating the waterman the governor and VMRC can continue to avoid the real issue and that is the degradation of the Chesapeake Bay.

    Great comment, Ken!

    I’m sure the halt of winter dredging in Virginia helped.

    Great comment Loudon Insider.

    And to quote Ken Smith:

    “It doesn’t take a rocket scientist to figure out that if you don’t take the crabs out of the water then there will be more in the water.”

    It also doesn’t take a rocket scientist to figure out that if you allow unlimited catches, and these unlimited catches result in depleting the population to unsustainable levels, we all lose.

    Being conservative at one time meant being for conservation. Not anymore. The GOP has been bastardized by the unlimited resource extraction folks. They want to get theirs now – to hell with future generations. That’s liberal, folks, not conservative.
