New tests by the Maryland Department of the Environment (MDE) show lower levels of contaminants in the Chesapeake Bay’s striped bass (rockfish), prompting the agency to increase its recommendation for the amount of the popular fish residents can safely eat.
Revised fish consumption advisories increase the recommended meal limits for striped bass caught in the Bay for nearly every population group.
The recommended meal limits for the general population for smaller striped bass increased by 50 percent, from two meals to three meals per month
The advisories no longer include the recommendation that had existed for women and children for certain striped bass
The new recommendations stem from recent test results that show a significant decline in PCB levels in striped bass from Maryland waters. Median PCB levels fell by more than half in fish analyzed between 2001-2005 versus in 2009-2010.
Data also suggest that contaminant levels are even lower in striped bass fillets prepared without fatty portions of the fish.
“Contamination has decreased in the striped bass we tested,” said MDE Acting Secretary Robert M. Summers. “Although we do not have the data to identify a specific explanation for the decline, PCBs have been banned in the United States since 1979, and we’re encouraged by this positive indication of the improving quality of our waters.”
MDE has also released new consumption advisories for bluefish caught in the Bay. Based on new data, MDE recommends a limit of two meals per month for bluefish less than 15 inches long. Residents should avoid eating bluefish larger than 15 inches.
Fish consumption advisories provide recommended limits on how often certain fish can be eaten and still enjoy health benefits while minimizing risks. For Maryland waters, fish consumption advisories are available on MDE’s website and posted at many public fishing areas.

Once a year a holiday comes around that is all about giving back and celebrating what we have been given. Trees are often an integral part of this celebration, which involves families coming together to celebrate and volunteer. It is Earth Day, of course! (What were you thinking it was?)
Earth Day began in 1970 as a nationwide rally for the environment. Since then it has evolved into a day of education and service. Local and national organizations around the country hold events and celebrations. Attending an Earth Day event is the perfect way to get your family outdoors and learn what you can do to help the environment.
Here are 21 Earth Day celebrations happening this month around the Chesapeake Bay watershed.

West Virginia will invest $6 million annually for 30 years toward wastewater treatment plant upgrades that will reduce nutrient pollution to the Potomac River and the Chesapeake Bay.
The money, which will come from excess state lottery funds, will fund about $85 million in bonds that will help pay for upgrades. The funding will cover about 40 percent of the expected cost for the upgrades.
The upgrades will help West Virginia meet new pollution-reduction goals that are part of the federal pollution diet for the Chesapeake Bay and its rivers. West Virginia has 13 wastewater facilities that need to be upgraded to meet nutrient limits.
Acting Gov. Earl Ray Tomblin signed the bill into law on April 6.
Welcome to the latest entry in our "Ask a Scientist" series! Each month, we take a question submitted through our website or Twitter (@chesbayprogram) and have a scientist from the Bay Program partnership answer it here on our blog.
Today’s reader question is about the effect of spring rainstorms on the Chesapeake Bay's health. We asked Scott Phillips, Peter Tango and Joel Blomquist, scientists with the U.S. Geological Survey and members of the Bay Program’s Nontidal Water Quality Workgroup, for their explanation on why heavy rains have such a big effect on the Bay and its local rivers.
They say April showers bring May flowers. But around the Chesapeake Bay, rainstorms bring a whole lot more.
The rain and snow that falls on the Bay watershed, an area of land that stretches from New York to Virginia, drains into local streams and rivers, which eventually flow to the Chesapeake Bay. About half of the water in the Bay comes from its rivers; the other half from the Atlantic Ocean.
The U.S. Geological Survey measures river flow throughout the Bay watershed and estimates the amount of fresh water that enters the Bay each month and year.Typically, 52 billion gallons of water drain into the Chesapeake Bay each day.
The river water that flows into the Bay has a significant impact on the Bay’s water quality, habitats, and fish and shellfish. Spring rains affect the amount of pollution going into the Bay. During periods of higher river flow, more nutrient and sediment pollution enters the Bay. During dry periods, fewer pollutants are washed into streams and carried into the Bay. In general, river flow into the Bay is highest during the spring, when there are more rain storms.
This past March started with noteworthy flooding across the watershed. River flows in March were some of the highest ever recorded. Field crews mobilized to collect nutrient and sediment samples that help determine the amount of pollution that washed into the Bay.
Too many nutrients and sediment contribute to pollution in the Bay and local streams. Elevated nutrient levels in the Bay tend to cause excessive algal growth. As algae decay, dissolved oxygen levels drop. This leads to unhealthy conditions for fish, crabs and other underwater life. Algae and sediment also block out sunlight that underwater grasses need. For these reasons, Chesapeake Bay Program partners are working to reduce these pollutants.
River flow also affects the salinity, or amount of salt, in the Bay’s water. The Bay’s salinity ranges from fresh water near the top of the Bay at Havre de Grace, Maryland, to ocean water near Norfolk, Virginia. In dry years, there is less river flow so saltier water moves further up the Bay. During wet springs, more fresh water enters the Bay, pushing salty water farther south.
Changes in salinity affect fish, oysters and underwater bay grasses. For example, some underwater grasses cannot survive if the water is too salty, while others can only survive in fresh water. Diseases spread to more oysters in saltier waters. Finally, sea nettles are more common in saltier water. So salinity and river flow influence our choice of places to swim to avoid frequent and painful jellyfish stings!
