CHRISTI LINARDICH: Fishing isn’t the problem

January 12, 2017 — “Let scientists manage menhaden approach” (editorial, Dec. 28) perpetuates the belief that so many people seem to have lately — that the largest impact on striped bass populations is lack of menhaden to eat.

According to the Atlantic States Marine Fisheries Commission, menhaden biomass was lowest during the mid-1990s to mid-2000s, but during that time (1993-2004, to be exact) striper recruitment was strong.

This is not easily explained, but neither is the simplified belief that taking a sustainable amount of menhaden out is magically taking striper off the end of people’s fishing lines.

Critics conveniently ignore the fact that the Chesapeake Bay and associated rivers, which striper depend on to complete their reproductive cycle and menhaden rely on for nursery grounds, has been severely altered by humans through dams and pollution.

VIRGINIA: Derelict pots killing 3.3 million crabs annually in the Bay

January 3, 2017 — When Virginia closed its winter dredge fishery in 2008, waterman Clay Justis turned his attention from catching crabs that season to collecting the gear that captures them.

He was one of several watermen hired under a program that taught them to use sonar to find and remove lost and abandoned fishing gear, primarily crab pots, littering the bottom of the Bay.

“As a waterman, I knew there was stuff on the bottom, but when I turned the machine on, I was like, ‘Wow!’” said Justis, who fishes out of Accomack on the Eastern Shore.

Out of sight in the Bay’s often murky water, crab pots lay scattered all over the bottom, the sonar showed — along with other fishing gear such as gill nets, and all manner of trash, even a laundry machine.

But the so-called “ghost pots” are a special concern because the wire mesh cages with openings to draw crabs in but not let them out can continue to catch — and kill — crabs and fish for years. They are taking a bite out of both the crab populations and the wallets of watermen. More often than not, Justis noted, the derelict pots he pulled up had something in them. “You’ve got fish, you’ve got crabs, you’ve got ducks. All kinds of things,” he said. But, he added, “most of the time, they are dead.”

Concern about delict crab pots in the Bay has been growing for a decade, and a new report for the first time attempts to estimate their Baywide impact. It found that more than 145,000 pots litter the bottom of the Bay — a number the report authors consider to be conservative.

Each year, the report estimated that those pots kill about 3.3 million crabs, 3.5 million white perch, 3.6 million Atlantic croaker, and smaller numbers of other species, including ducks, diamondback terrapins and striped bass.

The number of crabs killed amounts to 4.5 percent of the 2014 Baywide harvest, the report said. Nor is the problem limited to the Bay. Studies have found similar problems with fisheries that use “trap” devices to catch crabs and lobsters globally.

“It’s an issue that, around the country, folks may not be aware of unless you live close to an area where commercial fishing is a way of life,” said Amy Uhrin, senior scientist with the National Oceanic and Atmospheric Administration Marine Debris Program, which funded the study. “It is one of those ‘out-of-sight, out-of-mind’ issues.”

BEN LANDRY: Menhaden are flourishing

December 28, 2016 — A recent column by Chris Dollar (“Outdoors: The more menhaden the better,” Dec. 3) cites claims from the Chesapeake Bay Foundation that the current management of menhaden in the Chesapeake Bay has left the stock running low. The column also echoes the foundation’s position that the menhaden harvest cap should be lowered. The science suggests the opposite to be the case.

In 2012, based on fears of overfishing, the Atlantic States Marine Fisheries Commission implemented a menhaden quota. Soon after the quota was implemented, scientists found the concerns of overfishing were misplaced. Further research found that menhaden are prospering coastwide. In fact, the ASMFC declared conclusively that menhaden are neither “overfished nor experiencing overfishing.”

The ASMFC has recently expressed its confidence in the health of menhaden by voting to raise the coastwide quota by 6.45 percent. This decision was backed up by a commission analysis based on nearly 9,000 simulations that found that an increase in the menhaden quota would have an almost zero percent chance of leading to overfishing.

Got brook trout? Then you’ve also got a healthy stream

November 2, 2016 — “A wild trout in its native habitat is a compact example of the Earth working well.” — Christopher Camuto

The brook trout (Salvelinus fontinalis) is a small, brilliantly colored freshwater fish native to clear, cold streams and rivers in the headwaters of the Bay watershed. It’s also the state fish of New York, Pennsylvania, Virginia and West Virginia.

Brook trout are recognized by their dark green back covered with lighter, worm-shaped markings. These markings, resembling the pattern created when the sun shines through rippled water, help to camouflage brook trout from predators such as larger fish and herons and even fly fishers. Bluish sides are sprinkled with yellow spots and red spots surrounded by blue halos. The brook trout’s fins are starkly edged in white, which again is unique among other common trout.

These fish thrive in clear, silt-free, well-shaded freshwater streams with numerous pools and a substrate made of mixed gravel, cobble and sand. Because brook trout are not tolerant of water temperatures above 75 degrees Fahrenheit, they are rarely found in developed areas.

Brook trout are not picky eaters and eat a wide variety of food. Opportunistic feeders, they will eat whatever they can find, including: aquatic insects, like mayflies, caddisflies and stoneflies; land insects that fall into the water, like ants and beetles; small crayfish; and even small fish and minnows, but only when they are easy to catch.

Chesapeake Bay Foundation Shamefully Fundraises off of Inaccurate Menhaden Claims

October 28, 2016 — The following was released by the Menhaden Fisheries Coalition:

A September 27 fundraising email from Rob Beach, the Director of Community Building and Digital Media at the Chesapeake Bay Foundation, misrepresented accepted scientific conclusions about the health of the menhaden stock in the Chesapeake Bay in order to gain funding for the organization.

The Chesapeake Bay Foundation repeatedly described menhaden in the Bay as being “under threat from industrial fishing.” The most recent science on Atlantic menhaden shows that this is wrong.

In 2012, the Atlantic States Marine Fisheries Commission (ASMFC), which manages Atlantic menhaden, released the species’ latest updated stock assessment. Due to problems with the assessment model, the assessment suggested the menhaden stock was being overfished, a conclusion that has subsequently been found to be incorrect. As a result of this flawed assessment, the ASMFC slashed the annual menhaden catch by 20% as a precautionary measure.

Between 2012 and 2015, the menhaden stock assessment model was thoroughly reevaluated and updated with new tools and information that was previously unavailable. Consequently, when the 2015 benchmark stock assessment was released, it had reached a far different conclusion. It found that menhaden are neither overfished nor experiencing overfishing. This is a pattern that held for decades: in the assessment’s analysis, menhaden have not been overfished for nearly a half-century. Furthermore, the assessment found fishing mortality to be at an all-time low. This is especially significant, as it means that the impact of the commercial menhaden fishery is at its lowest point, and that regulators are already successfully managing the fishery.

In an effort to purposely mislead, the Chesapeake Bay Foundation claims that increasing the menhaden quota would change that reality. The science tells a different story. Recently, the ASMFC ran a comprehensive series of simulations to test the potential impact of various quota raises. The Commission concluded that raising the quota as high as 40% has a 0% chance of leading to overfishing.

Chesapeake Bay Foundation staff regularly attends meetings of the ASMFC; in fact, the group’s Director of Fisheries, Bill Goldsborough, has served in various roles with the ASMFC for nearly 25 years. It is shameful this fundraising campaign knowingly perpetuates misconceptions and inaccuracies about the health of a significant Bay fishery. It is using false fear to spur contributions.

Fearmongering for financial gain should be beneath the dignity of an organization that claims to be dedicated to “science-based solutions.”

VIRGINIA: VIMS developing tool to help anglers avoid unproductive ‘dead-zone’ water

August 26, 2016 — The Chesapeake Bay is often plagued with oxygen-poor “dead zones.” These dead zones occur more frequently in the warmer months of the peak fishing season.

These low-oxygen areas are avoided by fish. It would help anglers to know where these zones are so that they can avoid them also. The Virginia Institute of Marine Science is developing a tool to help with that. The VIMS’ daily dead-zone forecast will help anglers avoid unproductive water.

Maryland aquaculture leasing streamlined

August 19, 2016 — Federal regulators unveiled this week a new, “more streamlined” process by which Maryland oyster farmers can lease places in the Chesapeake Bay for raising their shellfish.

The revised permitting procedures announced by the Baltimore District of the U.S. Army Corps of Engineers come in response to long-voiced complaints from oyster farmers – backed up by Maryland’s U.S. senators – about delays and red tape in obtaining aquaculture leases.

The Corps said it is replacing a regional general permit, which it issued in 2011, with what it calls a Nationwide permit, which the agency says provides a “more streamlined” way to authorize new aquaculture activities.

The new process, which took effect Aug. 15, includes allowing unlimited acreage to be leased, and speeding up handling of proposed aquaculture projects by having federal and state officials review plans at the same time rather than sequentially.

Until now, oyster farmers were limited to leasing 50 acres if raising shellfish loose on the bottom, five acres if rearing them in cages and three acres if keeping them in floats near the water surface. If a grower wanted more, he or she had to apply for an individual permit, which required more review, more public notice and a hearing.

Biologists alarmed over lack of young Atlantic sturgeon in surveys

August 16, 2016 — Biologists have been surprised in recent years about how many big Atlantic sturgeon they are finding around the Chesapeake Bay. But rather than celebrating, they have become increasingly alarmed about what they are not seeing: a new generation of young sturgeon.

While finding more adults is certainly good news, biologists say they have seen little evidence those sturgeon have successfully produced significant numbers of offspring in recent years that would be critical if the endangered species is to make a comeback in the Chesapeake.

“To get any kind of recovery, the best thing you can do is to increase that first year of survival,” said Dave Secor, a fisheries biologist with the University of Maryland Center for Environmental Science. If young fish survive, he said, “you can actually realize very rapid recovery, even for a species like sturgeon.”

That’s something that biologists working with sturgeon around the Bay say they haven’t seen, perhaps for a decade or more. Many blame the absence of young sturgeon on a rampant population of introduced blue catfish, which they say could be consuming eggs and newly hatched fry, or outcompeting them for habitat.

But researchers who study the catfish dispute that, and even sturgeon specialists acknowledge they lack concrete evidence.

With droughts and downpours, climate change feeds Chesapeake Bay algal blooms

August 11, 2016 — Nitrogen-rich agricultural runoff into the Chesapeake Bay presents an ongoing environmental and economic concern for the bay’s massive watershed. Pollution from fertilizer application feeds algal blooms that poison humans and marine life, and devastate fisheries.

 While efforts to restore the bay have been successful during the past several years, a study led by Princeton University researchers shows that weather patterns tied to climate change may nonetheless increase the severity of algal blooms by changing how soil nutrients leach into the watershed.

Extreme rainfall cycles caused by increased climate variability flush larger amounts of nitrogen-containing nutrients from fertilizer and other sources into the Susquehanna River, which carries them into the Chesapeake Bay, according to a report in the journal Geophysical Research Letters. Moreover, a spike in rainfall can increase nitrogen levels in the bay even if the amount of fertilizer used on land remains the same.

These chemicals feed explosive algae growth that can produce toxins that harm people, fish, wildlife and drinking water. Decaying algae also suck oxygen from the surrounding water, creating a low-oxygen state known as hypoxia that results in “dead zones” that suffocate fish and other species important to the aquatic food chain.

The researchers constructed a model that they say provides the most complete picture to date of how nitrogen moves from place to place in the Chesapeake Bay watershed. It connects weather and pollution in places as far away as upstate New York to the water conditions in the bay.
