Photo Essay: Scientists restock American shad to Delaware waterway

For close to a decade, scientists and volunteers have spent their springs at the Nanticoke Shad Hatchery, working to rebuild populations of American shad. 

In this small building near Bethel, Del., hundreds of thousands of American shad are raised each year before they are returned to their native spawning grounds in the Nanticoke River. This spring, the hatchery stocked about 558,000 fish to the waterway.

In the early 1900s, excessive commercial harvests took a heavy toll on American shad. Over the past century, poor water quality and the construction of dams that restrict the anadromous fish’s access to upstream spawning grounds have caused shad populations to decline.

Today, restoration efforts are giving American shad a much-needed population boost. Restocking programs across the Chesapeake Bay watershed—combined with harvest restrictions, improved water quality and the removal of dams—are critical to the re-establishment of the species.

American shad spend most of their lives in brackish and saltwater before returning to their birth waters to spawn. The Nanticoke Shad Hatchery collects its brood stock directly from the Nanticoke River and its Deep Creek tributary to ensure adult fish will return to the waterway and to preserve the genetic integrity of the local shad population.

Throughout the spring spawning season, which runs from mid-March through April, mature shad that are held in the hatchery’s closely monitored, 3,500-gallon spawning tanks periodically release eggs and sperm.

On the morning after an overnight spawning event, pea-sized eggs are filtered into an egg collection tank.

“Bad eggs” are removed from the tank before fertilized eggs are measured by volume and placed in incubation jars to grow.

Eggs that survive to the “eyed” stage are moved to one of four culture tanks, where they will hatch into larval fish within a week.

After a few more days spent in the safety of the culture tanks, the larval fish absorb their nutritive yolk sac and transform into fry that are ready to feed on their own in their natural habitat.

Before the hatchery-produced fish are released into the Nanticoke River, scientists mark them with oxytetracycline. Tracking the fish will allow scientists to gauge their survival and stocking success over time.

Six years of sampling surveys on the Nanticoke River show that adult American shad abundance has increased, while the number of hatchery-produced juveniles has decreased. According to hatchery manager Mike Stengl, this suggests the hatchery is succeeding in its long-term goal: to reduce the percentage of hatchery-grown fish in the river and encourage the wild population to spawn on its own.

Success at the Nanticoke Shad Hatchery and at other hatcheries across the region are giving American shad a second chance at survival in the watershed.

Tributary Tuesday: Bohemia River (New Castle County, Del., and Cecil County, Md.)

The Chesapeake Bay was among the first regions settled by European explorers, and at one point, much of it was up for grabs. In the 1650s, Dutch conquistadors wanted to extend their rule of New Amsterdam (New York) into Maryland. They sent a man named Augustine Herrman to Maryland’s colonial capital, St. Mary’s City, to present their case to the governor. Herrman’s expedition left from New Castle, Delaware, and sailed down the modern day Bohemia River, to the Elk River, and then into the Chesapeake Bay. Although Herrman and his team weren’t able to convince the Maryland governor to allow the Dutch to move east, Herrman was so impressed with the region’s beauty that he himself decided to settle there.

After striking a deal with Maryland leaders, Herrman received 4,000 acres in northeast Maryland, between the Elk River and the Bohemia River (formerly named the Oppoquermine River). Since Herrman was a native of Prague, which was then Bohemia, he named his new home “Bohemia Manor” and renamed the river.

As part of the deal, Herrman agreed to create a map of the Chesapeake Bay. The detailed account of the region was used throughout the next century.

Herrman and his surveying crew predicted the concept of the Chesapeake and Delaware Canal, constructed nearly 150 years later. In 1661, he wrote, “the Mingaskil and aforesaid Bohemia River run there within a league [3 miles] from each other from where we shall in time have communication with each other by water."

As Herrman’s reputation and importance grew, he convinced Maryland leaders to make northeastern Maryland its own county; as a result, Cecil County was born, and the region was separated from Baltimore County.

Although the Bohemia was navigable in Herrman’s time, today, the 5-mile tributary to the Elk River in southwestern Delaware and northeastern Maryland has since filled with sediment from agricultural operations, rendering it unsuitable for boat navigation.

A drawbridge, known as the “Bohemia River Bridge,” allowed people and farm goods to cross the Bohemia until the late 1990s, when it was demolished. Today, Maryland Route 213 crosses the river in its place, providing gorgeous views of the meandering river.

More from the Bohemia River:

  • To learn more about the “First Lord of Bohemia Manor,” Augustine Herrman, read his biography.
  • This Bay Journal article provides a thorough history of the Bohemia River region.
  • Hunt, hike or just enjoy the scenery at Earleville Wildlife Management Area, just south of where the Bohemia River meets the Elk River.
  • Camp out at Elk Neck State Park, where the Elk River and North East River meet the Chesapeake Bay. Just a few miles downriver of the Bohemia, the park offers camping, lighthouse tours, a beach area and many other attractions.

Eight natural places to visit on the way to the beach this summer

Finally – school’s out and warm weather is here! We know you’re eager to get away to your nearest beach and bury yourself in the sand with a new book. But did you know there are dozens of beautiful parks and natural areas on the way to major beaches such as Rehoboth Beach, Virginia Beach and Ocean City? Here are eight places you can enjoy the beauty of the Chesapeake Bay and its rivers along the way to your summer destination. After all, some of life's greatest joys are in the journey, not in the destination!

Virginia Beach

1. Hoffler Creek Wildlife Preserve (Portsmouth, Va.)

Just 20 minutes west of Virginia Beach, Hoffler Creek Wildlife Preserve provides urban wildlife in the Norfolk/Portsmouth metro region with 142 acres of tidal and non-tidal habitat. Expect to encounter foxes, river otters, oysters and crabs along the preserve's trails. Before you go, check out Hoffler Creek’s events listings for specialties like sunset kayak tours, night owl kayak paddles by moonlight, and early morning bird walks!

2. Dutch Gap Conservation Area (Chester Va.)

Just south of Richmond, Dutch Gap Conservation Area surrounds Henricus, the second successful English settlement in Virginia. Bordered by the James River, the 810-acre area contains a blue heron rookery and has been described as a "birder's dream." A diversity of habitats attract a range of flying friends: in wetlands, look for pintails and kingfishers; in meadows, you'll find goldfinches, indigo buntings and kingbirds; and in forests, expect to see scarlet tanagers and red-eye vireo. Hike or bike the 4.5 mile Dutch Gap Trail, which circumnavigates a tidal lagoon. Kayak or canoe the Lagoon Water Trail (perfect for beginner paddlers), or schedule a night to camp under the stars at the area's primitive camp site.

3. Eastern Shore of Virginia National Wildlife Refuge (Cape Charles, Va.)

Drive over the Chesapeake Bay Bridge Bay Tunnel near Virginia Beach to arrive at the southernmost tip of the Delmarva Peninsula. Here, nearly 1,300 acres of tidal wetlands and hiking trails sport colorful views of sunsets and sunrises; enjoy being surrounded by water on three sides! The area is one of the most important avian migration funnels in the country, meaning it provides vital stopover habitat for birds and butterflies migrating south for the winter and north for the summer. Return in the winter for a trip to Fisherman Island, a remote island home to sensitive bird species and untouched shoreline.

Ocean City and Assateague Island

4. Nassawango Creek Preserve of the Nature Conservancy and Furnace Town (Snow Hill, Md.)

Nassawango Creek

Just south of Salisbury, Maryland, one of the northernmost stands of bald cypress trees leak tannins into the Nassawango Creek, giving this pristine Chesapeake Bay tributary a deceptive tea-like color. Bald cypress trees grow completely in the water, and are most abundant in swamps in the deep southeast United States. Visitors to the 15,000-acre Nassawango Creek Preserve can paddle among these green giants or explore upland forest habitat on the preserve's many trails. Expect to see rare plants like indian pipe and pink lady slipper, and migratory birds such as scarlet tanagers and prothonotary warblers.

Along the edge of the preserve, hidden in the Pocomoke State Forest, a brick structure stands tall among the trees. It is the remnants of an iron furnace that at one time attracted hundreds of people – miners, firemen, bargemen and sawyers – to the area. From 1831 to 1850, village residents gathered iron ore from the bogs surrounding Nassawango Creek and loaded iron bars onto barges that were floated down the creek to the Pocomoke River and the Chesapeake Bay. Today, you can get a glimpse of what life was like in the 1830s mining village by visiting the Living Heritage Museum.

5. Pickering Creek Audubon Center (Easton, Md.)

If you're driving to Ocean City or Assateague Island, you'll likely pass hundreds of cornfields, strawberry fields and trucks full of chickens. Farming is a significant part of the heritage of Maryland's Eastern Shore, but the agricultural industry is often blamed for polluting the Chesapeake Bay.

At Pickering Creek Audubon Center in Easton, 270 acres are farmed according to "best management practices" that reduce the amount of animal bacteria, chemicals and pesticides that end up in the bay. Visitors can learn the past and future of farming in the region, or hike through hardwood forests, fresh and brackish marshes, meadows and wetlands. A Children's Imagination Garden will let your little ones connect to nature, and a display of live reptiles allows them to get up close and personal with our scaly friends!

Rehoboth Beach

6. Trap Pond State Park (Laurel, Del.)

Trap Pond

Trap Pond was created in the late 1700s to power a sawmill during the harvesting of bald cypress trees from these southwestern Delaware freshwater wetlands. Fortunately, not all of the trees were harvested, and today, Trap Pond provides a home for the northernmost stand of bald cypress trees in the United States. The thick bald cypress marsh envelops visitors in a blanket of shade, making this park the perfect destination for a hot summer day.

Within the park, Trussum Pond is the best place to view the largest of these trees. Biking, camping, boating and disc golf are just some of the recreational opportunities available at the 2,700 acre park.

7. James Branch Nature Preserve and Water Trail (Laurel, Del.)

Unlike Trap Pond, which, as a state park, exists primarily for recreational purposes, James Branch Nature Preserve's first priority is protecting and enhancing a delicate ecosystem for future generations. As the largest of the state's nature preserves, James Branch's 685 acres are mostly composed of bald cypress trees – the oldest-growth in the state! Visitors can canoe and kayak the James Branch Water Trail. Since there is the chance of encountering downed trees, low-hanging branches, and floating and submerged logs, the trail is only recommended for intermediate to advanced paddlers.

 8. Adkins Arboretum (Ridgely, Md.)

Adkins Arboretum

For some people, it's difficult to imagine your garden untouched by invasive, exotic weeds aggressively overtaking native vegetation. But at Adkins Arboretum, you can explore 400 acres of native plant gardens and wildflower meadows. Adkins is the only public garden or arboretum that focuses solely on plants native to the mid-Atlantic coastal plain. Located at the intersection of the piedmont and coastal plain, and the junction of the north and south, Adkins supports more than 600 species of native shrubs, trees, wildflowers and grasses. Visitors can understand nature through the lens of art and history; an ongoing art exhibit features natural themes by regional artists, and Adkins describes nature's relationship to the Underground Railroad throughout the region. Before you visit, be sure you check the arboretum’s list of programs and guided walks.

States, D.C. submit final Chesapeake Bay cleanup plans to federal government

Six of the seven Chesapeake Bay jurisdictions – Delaware, Maryland, Pennsylvania, Virginia, West Virginia and the District of Columbia – have submitted their final cleanup plans as part of the Chesapeake Bay TMDL, a “pollution diet” that aims to put in place all restoration measures needed for a clean Bay by 2025.

The final cleanup plans, officially known as Phase 2 Watershed Implementation Plans (WIPs), were submitted to the U.S. Environmental Protection Agency last Friday. New York submitted its draft plan, and is working with the EPA to finalize that plan.

The cleanup plans were developed by each individual state and the District, working closely with counties, municipalities and other local partners. The cleanup plans identify specific restoration measures each jurisdiction will take to reduce nitrogen, phosphorus and sediment pollution to the Bay and its local rivers.

According to the guidelines set in the TMDL, at least 60 percent of necessary pollution reductions must be achieved by 2017. Chesapeake Bay Program partners have committed to putting all needed pollution control measures in place no later than 2025.

Visit the EPA’s Chesapeake Bay TMDL website to review and learn more about the cleanup plans.

Tributary Tuesday: Marshyhope Creek (Delaware and Maryland)

Agricultural ditches in Kent County, Delaware, flow through farm fields and into Marshyhope Creek, a 37-mile-long tributary of the Nanticoke River. This scenic waterway begins in Harrington, Delaware and runs across the Maryland state line, meandering through Caroline and Dorchester counties before emptying into the Nanticoke River at Sharptown.

Outdoor enthusiasts should explore the 3,800-acre Idylwild Wildlife Management Area, located east of the Marshyhope in Caroline County. A mix of agricultural fields and forests attract red-crested pileated woodpeckers, as well as bluebirds, beavers, wild turkeys, woodcocks, gray foxes and more. Idylwild will please anglers, hunters and wildlife watchers alike. Bring your bike, ATV or hiking shoes and hit the trails.

Marshyhope Creek also winds through Federalsburg, a quaint Maryland town whose slogan is “Pride in the Past, Hope in the Future.” The town’s name comes from a Federalist Party meeting in the early 19th century. If you’re fond of hiking and biking, you’ll want to check out the 2.5 mile Marshyhope Hike and Bike Trail in town. Be sure to cross the Harrison Ferry Bridge to get an excellent view of the Marshyhope.

Tributary Tuesday: Pocomoke River (Delaware and Maryland)

Bald cypress trees emerge from the water, their branches convoluted and their greenery draping, haunting and lush. Their structure is impressionistic, and somehow looks more like a painting than a photograph. The scene seems to belong in Louisiana, Mississippi or any other place you’d expect to find alligators, Cajun river monsters and Spanish moss…

Nassawango Creek

But this is Delaware – Sussex County, home of the Great Cypress Swamp. This forest – the largest of its kind on the Delmarva Peninsula – forms the headwaters of the 73-mile-long Pocomoke River, the Chesapeake Bay’s easternmost tributary. With depths ranging from 7 to 45 feet and a width of less than 100 feet, the Pocomoke is rumored to be the deepest river for its width in the world.

At the Great Cypress Swamp, you can walk (or boat) among the northernmost stands of bald cypress in the United States.  How do these swamp giants survive in high water? Their “knees,” of course! Bald cypress trunks have “knees,” or knots near the water’s surface, which allow the trees to send oxygen from the air down into their root system underwater…kind of like a snorkel!

Acid from the bald cypress roots contributes to the Pocomoke’s dark, tea-stained color. This may be what gave the river its name; locals will tell you that Pocomoke means “black water.” However, experts will tell you that it means “broken ground,” referring to the indigenous tribes’ farming methods. I’m not sure who’s right or wrong, but the color of the water is unique. As one writer put it, the Pocomoke’s water offers the perfect reflection surface for cypress and other trees that line the river banks.

As the Pocomoke flows south into Maryland, it forms the boundary between Wicomico and Worcester counties. At Porter’s Crossing, the river begins to narrow as it flows southwest. It runs through Snow Hill and Pocomoke City before emptying into Pocomoke Sound in the Chesapeake Bay.

Along the way, you can find birds – and lots of them! One hundred seventy-two different species have been recorded in the area. The Pocomoke’s marshes are some of the best places in the Atlantic Flyway to observe both warblers and waterfowl.

If you’d like to take to the “black water” yourself, check out local canoe and kayak rental companies in Pocomoke City and Snow Hill. Hiking trails in Pocomoke River State Forest, Pocomoke River State Park and the Nassawango Preserve of The Nature Conservancy reveal views of the swamps surrounding the river. If you’re lucky, you can get up-close and personal with some of the river’s non-human residents!

For you history buffs, be sure to visit the Furnace Town Living History Museum, a nature and archeology site dedicated to preserving the history of the Nassawango Iron Furnace, started in 1829 near Snow Hill.

Fishing is also excellent in the Pocomoke. Expect to find largemouth bass and panfish, but keep a lookout for pickerel and longnose gar. Since the Pocomoke is a tidal tributary, figuring out the tides is key to having a good fishing experience!

Invasive snakehead fish found in Maryland, Delaware rivers

The northern snakehead – an invasive fish native to Asia – has been discovered for the first time in several Maryland and Delaware rivers that flow to the Chesapeake Bay.

This month, a team with the Smithsonian Environmental Research Center found a mature, egg-bearing snakehead in the Rhode River, just south of Annapolis. It was the first snakehead ever found in the Rhode River.

After the discovery of the Rhode River snakehead, officials with the Maryland Department of Natural Resources (DNR) confirmed that another snakehead had been found in the Northeast River in Cecil County this spring.

Also this month, a Delaware angler caught a snakehead in Marshyhope Creek, a tributary of the Nanticoke River. According to the Delaware Department of Natural Resources and Environmental Control (DNREC), this was the second snakehead found in the Nanticoke region. Last fall, DNREC staff found a snakehead in Broad Creek, near Laurel.

The northern snakehead was first discovered in the Bay watershed in a pond in Crofton, Maryland, in 2002. Since then, it has become established in the Potomac River and several of its tributaries in Maryland and Virginia. Snakeheads have the potential to be invasive because they breed rapidly and prey on native fish.

Snakeheads are freshwater fish, so the Bay’s brackish waters usually prevent them from leaving the Potomac River. But scientists believe it is possible that unusually low salinity in the Bay this summer allowed snakeheads to travel to new rivers.

It is illegal to move, possess or release snakeheads in Maryland and Delaware. It is also illegal to transport snakeheads across state lines without a federal permit. If you catch a northern snakehead in Maryland or Virginia, you are required to kill it. These laws are intended to help prevent this potentially invasive fish from spreading.

For more information about snakeheads, visit Maryland DNR’s website.

Amid new development, road retains "sense of place" on Maryland's Eastern Shore

On any given afternoon, thousands of cars and trucks speed along Route 301 on Maryland's upper Eastern Shore, rolling past forests, rivers and soybean fields on their way north to Delaware or south to the Bay Bridge.

Staff with Adkins Arboretum hope motorists will soon travel on Route 301 for another reason: to see the road itself.

Since early 2002, the arboretum has led the Eastern Shoreway Alliance, a partnership of local organizations and individuals interested in conserving the rural character of this well-traveled road. The group's mission is to protect the stretch of Route 301 between Queenstown, Maryland, and the Maryland/Delaware state line from the development and urbanization threatening many of the Eastern Shore's most scenic areas.

“We want to preserve a sense of place, so you know where you are in the world,” said Ellie Altman, executive director of Adkins Arboretum and co-chair of the Eastern Shoreway Alliance. Much of that “sense of place” has already been lost around the Chesapeake Bay region, as chain restaurants and retail stores make once-unique towns look like any other place in the United States.

Take a drive north on the Eastern Shoreway — the name the Alliance has chosen for Route 301 — into Delaware, and the threat becomes a reality. New homes, stores, hotels and restaurants sit atop land where corn and soybeans grew just a few years ago. Bulldozers and “land for sale” signs along the road indicate that more development is on its way.

This type of development is not unique to Delaware. Across the Bay watershed — and the country — new construction is concentrated along existing major roads. Although roads are necessary to modern life, they are often gateways to development and the first places where gas stations and strip malls pop up.

Back on the Maryland portion of Route 301, the scene is much closer to the traditional image of rural Delmarva. Volunteers with the arboretum have been working hard to protect this landscape by removing invasive plants and restoring meadows along the road. Dozens of signs mark these areas, which soak up excess polluted runoff and provide habitat for beneficial birds, bugs and butterflies.

With the addition of these meadows, the Eastern Shoreway now acts as a “linear arboretum” where travelers can see some of the Eastern Shore's native plants and flowers outside of Adkins' 400-acre facility in Ridgely, Maryland, according to Altman.

Through its website, the Eastern Shoreway Alliance markets the road as a travel destination for tourists from Baltimore, Philadelphia and Washington, D.C. And next year, one of the group's biggest goals will be achieved when the Eastern Shoreway is printed in the Maryland State Highway Administration's Scenic Byways Guide. It will be one of the state's few high-speed roads designated as a "scenic byway."

“Normally you think of scenic byways as backroads, not highways,” said Altman. “But highways can — and should — be beautiful, too.”

From the beginning, the State Highway Administration has been a willing participant in this project. The Eastern Shoreway Alliance is working with the agency to reduce mowing along the highway and put up signs at the crossings of the Chester and Sassafras rivers, two Bay tributaries. The group also wants to add literature on the road's significance to the highway's welcome center.

The effort isn't perfect. Billboards litter a few points along the road, advertising politicians, available land and car insurance companies. Although encroaching development can't be stopped entirely, the Eastern Shoreway Alliance hopes that future structures can be built in a way that does not harm the road's natural scenery.

Most importantly, the group has managed to garner support and build a sense of urgency among the area's residents to protect the land along this “beautiful highway.”

“People think it will be here forever,” said Altman of the road and its unspoiled scenery. “We want to interpret, protect and restore the road's environment and show travelers that you can have development that fits in with nature.”
