Maryland Wants to Take shells for oyster project from prime fishing reef

MARYLAND – March 22, 2016 — Seeking to counter a shortage of oyster habitat in the Chesapeake Bay, the Maryland Department of Natural Resources is renewing a controversial bid to dredge old shells that have built up over centuries from an ancient reef southeast of Baltimore. Reviving a plan abandoned in 2009, the DNR has applied to the U.S. Army Corps of Engineers for a permit to take 5 million bushels of shells from Man-O-War shoal just beyond the mouth of the Patapsco River. Ultimately, though, the state wants to barge away 30 million bushels, or about a third of the 456-acre reef.

The shells are needed to replace or augment oyster reefs worn down by harvesting and buried under an accumulation of silt, the DNR said. State officials said they would use much of the dredged shell in future large-scale, restoration projects. Some would also go to help the public fishery, though and to assist oyster farmers growing bivalves on leased plots of the Bay and its tributaries.

But the DNR’s request is drawing flak from conservationists, fishermen and even some watermen who might benefit.

MARYLAND: New seafood industry group lobbies against oyster project

MARYLAND – March 22, 2016 –A new group has emerged to speak for the seafood industry in contentious Chesapeake Bay fisheries issues, and it’s already being heard in Maryland on oyster restoration.

The Delmarva Fisheries Association formed last year with the stated intent of bringing together watermen, restaurant owners, packing houses, oyster farmers and boat captains.

Capt. Robert Newberry, the association’s president and founder, used to oyster in the Upper Bay and is now a charter boat captain and a hunting guide. He said he wanted to form a group that would unite the seafood industry.

One of their first priorities, he said, was getting Maryland’s governor to take a closer look at the oyster reef construction project in the Tred Avon, which is part of an effort to restore bivalves in three of the state’s tributaries that will cost tens of millions of dollars. All three have been designated sanctuaries, off-limits to commercial harvesting.

Chesapeake Bay Nothing Like Caribbean

February 14, 2016 — In his letter, “Menhaden are critical for bay restoration,” Tscharner D. Watkins III begins with a protracted discussion of the Chesapeake Bay ecosystem before resorting to hyperbole. Referring to the menhaden, he states “these filter feeders kept our waters clear, much like the waters in the Caribbean.”

The Chesapeake Bay is a tidal estuary of the Atlantic Ocean — which is also fed by more than 150 streams and rivers within its watershed, emanating from six states and the District of Columbia. Thus it contains the same saline waters of the Atlantic, but has not borne within the past (nor does it continue to bear) any resemblance to the more pristine waters of the Caribbean Sea.

The marine dead zones are hypoxic waters which are so depleted of oxygen that they are unable to support life, resulting oftentimes in massive fish kills. The oxygen-robbing algal blooms which are symptomatic of the hypoxia are caused by the problematic runoff of residential, agricultural and industrial effluent throughout the watershed. Therefore, the menhaden are ill-affected by the disruption in the marine food chain, but should not necessarily be regarded as the root cause of the hypoxia.

Omega Protein Upholds ‘Gentlemen’s Agreement’, Avoids Fishing Near Virginia Beach

January 29, 2016 — The following was released by the Menhaden Fisheries Coalition:

In July of last year, Menhaden Fisheries Coalition member Omega Protein met with recreational fishermen from the Virginia Beach area to discuss and resolve potential issues arising from menhaden fishing in the area. At the summer meeting, the two groups reached an informal agreement, whereby Omega Protein would not fish within three miles of shore of an area extending from Cape Henry Lighthouse to the Sandbridge fishing pier, some of Virginia Beach’s most popular tourist areas (See the image below, taken from this WAVY report).

Since then, Omega Protein has kept its promise to avoid these areas. The images below are maps of menhaden fishing activity in the Virginia Beach area, provided by the Beaufort Laboratory of NOAA’s National Marine Fishing Service.

Press accounts in December 2015 referenced sightings of Omega Protein vessels fishing offshore in the vicinity of the Chesapeake Bay Bridge Tunnel in Virginia Beach as evidence that the agreement was violated. In fact, any sightings of fishing vessels in that locale would have been outside the agreed-upon area, and well within legally regulated fishing zones.

The image on the left shows fishing activity through July 2015, before the agreement was reached. The image on the right shows activity from the end of July through remainder of the 2015 fishing season. Since the agreement was entered into, there has been no menhaden fishing in the Virginia Beach three-mile buffer zone; all menhaden fishing activity in southern Virginia has taken place outside of the agreed-upon off-limits area. As shown in these maps, Omega Protein vessels adhered to the “Gentlemen’s agreement” for the remainder of the fishing season.

Removal of derelict fishing gear has major economic impact

January 22, 2016— A new study by researchers at William & Mary’s Virginia Institute of Marine Science shows that removal of derelict fishing gear could generate millions of dollars in extra harvest value for commercial fisheries worldwide.

The study focused on a 6-year, collaborative program to remove derelict crab pots from Chesapeake Bay, showing that the effort generated more than $20 million in harvest value for area watermen.

Extending their methodology to estimate the economic benefits of removing derelict crab pots and lobster traps on a global basis, the researchers showed that removal of even 10% of derelict pots and traps from major crustacean fisheries—the percentage of the Bay’s derelict pots they estimate were removed by the VIMS program—could increase landings by 293,929 metric tons, at a value of $831 million annually.

These fish started life as boys. Now scientists aren’t sure what sex they are.

For male smallmouth bass, sex change is increasingly not an option. In the chemical-laced Chesapeake Bay watershed and in rivers up through New England, it comes with the territory.

Based on the latest U.S. Geological Survey on intersex fish, 85 percent of male smallmouth bass in waters in and around national wildlife refuges in the Northeast have developed “characteristics of the opposite sex.” That’s in addition to 90 percent of the species in some West Virginia waters and 50 percent to 100 percent in the southern stretch of the Potomac River. All of the affected fish had eggs where their testes should be, according to previous studies.

Why this is happening remains a mystery, says the lead author of a new study, despite the problem being detected more than a decade ago. “It is not clear what the specific cause of intersex is in these fish,” said Luke Iwanowicz, a USGS research biologist. “This study was designed to identify locations that may warrant further investigation.”

Could invasive lionfish end up in Chesapeake Bay?

December 29, 2015 — Few fish are as lovely as the lionfish. Few are as venomous.

A frilly, colorful native of the clear tropical waters and reefs of the South Pacific and Indian oceans, the lionfish has been a favorite of aquarium hobbyists for years.

In the Atlantic, however, it was unknown.

Then in the 1980s genetic researchers believe a handful of hobbyists in Florida, perhaps thinking it a kindness, released their aquarium pets into the wild ocean.

At that point, the lionfish proved they aren’t just lovely and venomous — they also breed like rabbits on Viagra. Ravenous eaters, they gobble up any smaller fish they spot and easily displace native species. And because nothing in this part of the Atlantic recognizes them as prey, their population has exploded into a serious and unfortunate marine invasion.

“It’s gotten really bad,” said Richard Brill, fishery biologist at the Virginia Institute of Marine Science in Gloucester Point.

“There’ve been some efforts in Florida and some parts of the Caribbean to get people to eat them. And there’s been some efforts — and this is pretty crazy — but groups of recreational spear fishermen have been spearing them and then feeding what they catch to sharks, trying to convince the local shark population to eat these things.”

The hardy little invaders have established year-round populations from the Gulf of Mexico to the Outer Banks. They’ve been spotted in warmer months as far north as Massachusetts, although they can’t survive the northern winters.

Scientists worry that the Chesapeake’s natural shoreline is turning into a wall

December 26, 2015 — On the banks of the Potomac River, construction cranes that look like metal dinosaurs tower over Southwest Washington. They swivel in all directions, delivering concrete and other heavy material to workers building a large development behind a steel-and-concrete wall that holds back the water.

Within two years, the Wharf will begin emerging as a playground of trendy apartments, shops and entertainment venues. But below the river’s surface, animals that depend on vegetation in the water may continue to struggle, marine scientists say.

The Wharf is part of the great wall of the Chesapeake Bay. Because of development along the bay and its rivers, vast swaths of soft shorelines have been turned into stone. The spread of what scientists call “the armored shore” is depriving young fish, crabs and other organisms of food and shelter. And it is yet another reason why life in the bay is disappearing, according to new research funded by the National Oceanic and Atmospheric Administration.

Houses, offices, bike paths, marinas — and walls built to protect them from erosion and rising sea levels — are replacing marshy shores, uprooting plants that young fish, crabs and other organisms use for food.

Virginia Delegate introduces menhaden bills

December 22, 2015 — Virginia Delegate Barry D. Knight once again has introduced legislation that would put the regulation of menhaden into the hands of the Virginia Marine Resources Commission instead of the General Assembly.

Menhaden is the only species of fish swimming in Virginia’s saltwaters that isn’t regulated by the VMRC.

Bay anchovies appear to be more important than menhaden in predators’ diets

December 7, 2015 — The Chesapeake Bay may be the best-studied estuary in the world, but a group of scientists attending a recent workshop were surprised about how little they knew about what predatory fish eat.

After all, menhaden — dubbed by some as the “most important fish in the sea” would also be the “most important” fish in the Bay, right?

Apparently not. That honor, were one species to be singled out, might belong to the tiny bay anchovy — a fish that rarely grows more than 3–4 inches in length and typically doesn’t live longer than a year.

“They’re the most abundant fish in the Bay,” said Ed Houde, a fisheries scientist with the University of Maryland Center for Environmental Science, who helped organize the workshop. “They’re really important in the Bay’s food web.”

An analysis of 12 years of Baywide diet information for five major predators prepared for the workshop found that bay anchovy was a significant portion of the diet for four of those species. Menhaden was important for only one, striped bass, and even for them, bay anchovy were more important.

“Menhaden came out not as high on the list as people thought it was going to be,” Houde said. “It was an important prey, but it certainly wasn’t in the top three or four.”

Even more significantly, the analysis showed that the Bay’s food web is less of a fish-eat-fish world than popularly thought, even among many scientists. A host of unheralded species, from worms to clams to crustaceans, are major food sources for the Chesapeake’s predatory fish.
