NOAA Fisheries Considers Moving Trawl Surveys to Fishing Vessels

August 2, 2016 — The following was released by NOAA:

NOAA Fisheries is initiating a planning process to support its intention to transition part or all of the Northeast Fisheries Science Center’s spring and fall bottom trawl surveys from the NOAA Ship Henry B. Bigelow to fishing industry vessels provided that survey data collection quality and time series integrity can be maintained.

“The bottom trawl survey is perhaps the most valuable ecological data set that we maintain at the Center,” said Bill Karp, the center’s director. “Those data are critical for many of the fishery stock assessments in the region and are mined by a wide variety of researchers for other purposes. By sharing the responsibility for gathering these data with the fishing industry, I think there will also come greater shared confidence in the results obtained using them.”

A typical survey covers about 400 stations off the Northeastern U.S. in the Gulf of Maine, On Georges Bank and south to Cape Hatteras. The scientific trawl is towed to collect marine species, while a variety of environmental and oceanographic data are also being collected. Biological samples are taken from trawled animals for a variety of studies and to calculate an index of catch per tow by species. The resulting data are used to study everything from food habits to habitat use and the effects of climate change.

Transitioning such a large-scale data gathering enterprise to commercial vessels is a complex challenge, but Karp notes it has been done in the past, both when it needed to move from one research vessel to another and elsewhere in the world where commercial fishing vessels are used for this purpose. “It’s important to note, “said Karp, “that this will happen providing we can also maintain survey data collection and time series integrity.”

The target timeframe for the transition is five years. A science center working group is being established to develop options and criteria for making the shift. They will work closely with industry during this process through the Northeast Trawl Survey Advisory Panel, convened jointly by the Mid-Atlantic Fishery Management Council, the New England Fishery Management Council, and the Atlantic States Marine Fisheries Commission.

The NEFSC bottom trawl survey is the longest-running of its kind in the world. The first trip was in May 1963, and since then seasonal surveys have been conducted annually. The surveys are conducted from government research vessels operated by NOAA and her predecessor agencies.

BILL GERENCER: Fishermen needlessly on the hook for uncertainties of stock estimates

June 2, 2016 — BOWDOIN, Maine — Proper stock assessments are the key to sound fisheries management here in New England. The current and now primarily survey-based assessments are heavy with uncertainty and always assumed to be overstated. Given the changes in the available stock assessment data created by 20 years of regulations, the uncertainty only seems to be increasing.

The fact that the R/V Bigelow, the National Oceanic and Atmospheric Administration’s primary fishery research vessel, delayed the survey this year is a significant threat to fishermen: We have been told that there are very few codfish in the Gulf of Maine, but this spring, fishermen have found it impossible to set a net in the water without catching codfish. This does not correlate well with the assessment advice.

Many boats have simply tied up to avoid codfish. The late start taken by the survey cruise has most likely missed significant codfish “data” as the research vessel remained at the dock.

Even with an on-time start, the survey method employed by the R/V Bigelow covers only a tiny sliver of the available fishing bottom and puts the survey gear on the bottom for a very short time during trips made in the spring and fall. The R/V Bigelow has also become famous in the fishing community for its demonstrated inability to catch cod and flatfish alongside commercial vessels catching those species and in areas fishing boats declared off limits to themselves because of the presence of codfish.

The low annual catch limit for codfish is tied directly to the low numbers provided by the most recent stock assessments. The low limit has resulted in small codfish allocations to each commercial fishing boat. Once a boat harvests its cod allocation, it will be prohibited from fishing for the duration of the fishing year even if it has significant allocation of other species.

How do you get a $450,000 camera off the bottom of the sea?

May 26, 2016 — The following is excerpted from a story published today by the Boston Globe:

Shortly after dawn last Friday, the R/V Hugh R. Sharp was towing a sophisticated array of sensors and cameras along the bottom of the Atlantic Ocean. Then suddenly, the research vessel shuddered.

Within seconds, the line went slack, and the team of scientists and volunteers realized the $450,000 camera system was lost, somewhere off the Virginia coast.

Officials at the National Oceanic and Atmospheric Administration said they believe the cable connecting to the camera system, known as HabCam, snagged on the remains of the Bow Mariner, a well-known wreck in the area.

The scientists lost contact with the HabCam as a college student was piloting it. HabCam, which is about 10 feet long and weighs 3,700 pounds, was at a depth of about 240 feet, some 90 miles southeast of Delaware Bay.

The Sharp has only several weeks available in the spring to survey scallops, which last year had a catch valued at nearly $425 million, more than three-quarters of which went to fishermen in New Bedford.

Those representing fishermen said they’re deeply concerned about the prospects for this year’s survey.

“This will create uncertainty in the scallop assessment, meaning there’s a greater chance that we’ll catch too few scallops, which will be a short-term loss, or too many, which will be a long-term loss,” said Drew Minkiewicz, an attorney for the Fisheries Survival Fund, a trade group that represents scallopers throughout the Northeast.

Some in the fishing industry blame NOAA for allowing a college student to pilot the HabCam. They also raised questions about whether the incident occurred as a result of problems with another NOAA ship, the Henry B. Bigelow, which required unexpected maintenance this spring that delayed its survey of groundfish stocks more than ever before.

“I’m told that because of the Bigelow fiasco, [NOAA] transferred more experienced people from the scallop survey to the groundfish survey to try to make up for lost time,” said Robert Vanasse, executive director of Saving Seafood, a Washington-based group that represents the fishing industry.

“Since the volunteer wasn’t as experienced, and since the captain was apparently driving directly into the path of a 600-foot sunken tanker, they didn’t react quickly enough,” he added.

Saving Seafood Executive Director Talks Lost NOAA HabCam

 

WASHINGTON (Saving Seafood) – May 25, 2016 — A $450,000 camera used to survey scallops on the ocean floor was lost Friday when a NOAA-chartered vessel towed it too close to a known ship wreck, as reported yesterday by the New Bedford Standard-Times.

This morning, Saving Seafood Executive Director Bob Vanasse spoke with New Bedford 1420 WBSM morning host Phil Paleologos about the accident, saying it proves the need for changes to the Atlantic scallop survey.

“The Fisheries Survival Fund [which represents members of the Atlantic scallop fleet] has been arguing for some time that the Federal scallop survey should not be done just by one single piece of equipment on one single vessel, but that there should be backups,” Mr. Vanasse said.

Compounding the problem the lost camera will have on this year’s Federal scallop survey is the fact that respected scientist Kevin Stokesbury, from UMass Dartmouth’s School for Marine Science and Technology, did not receive government funding for his own survey. Dr. Stokesbury’s surveys, which use cameras dropped into the ocean to take pictures of the seafloor, had previously been funded every year since 1999.

Mr. Vanasse called the loss of NOAA’s HabCam habitat camera last week “a combination of really bad circumstances.” He raised concerns about researchers aboard the R/V Hugh R. Sharp piloting the expensive HabCam so close to the well-known and charted wreckage of the Bow Mariner, where a cable apparently snagged the sunken ship and detached the camera. He also pointed out that many industry leaders raised concerns that a volunteer worker was piloting the HabCam at the time of the accident.

NOAA researchers are beginning efforts to find the HabCam today, nearly a week after it was lost, and say they will be able to make up for lost time. But scallop industry experts are unconvinced, according to Mr. Vanasse.

“That doesn’t really make sense,” Mr. Vanasse said of the industry perspective. “If they plan to go out for a certain time, they do that because they need it.”

The timing issue is further complicated because NOAA leases the Sharp from the University of Delaware for a limited period of time at high expense. Even if NOAA is able to salvage the HabCam, it will likely take more than a week of valuable time, Mr. Vanasse said.

The lost HabCam is not the first issue NOAA has had a with a research vessel in recent weeks. Earlier this month the R/V Henry B. Bigelow, the ship that surveys for groundfish and many other species on the East Coast, was delayed due to mechanical issues with its generators. The Bigelow was already running more than a month behind before its generator problems. Mr. Vanasse pointed out that Dr. Bill Karp, director of the Northeast Fisheries Science Center, has been pushing for NOAA to charter commercial fishing boats as backups, including at April’s NEFMC meeting (skip to 31:51 to listen to Dr. Karp).

“We need higher ups at NOAA to listen to what Dr. Karp has been saying about needing backups on the groundfish survey,” Mr. Vanasse said. “And we need everybody at NOAA to pay attention to what the [Fisheries] Survival Fund has been saying about having backups on the scallop survey.”

Survey delay might hurt fish population research

May 12, 2016 — The following is an excerpt from a story published today by the Boston Globe.

NEWPORT, R.I. – Even before mechanics found deeply pitted bearings near crankshafts in its generators, problems that could have led to catastrophic engine failure, the Henry B. Bigelow was running more than a month behind.

Now, the government research vessel is embarking on its annual spring voyage later than ever before, a delay that could have serious consequences for scientists’ ability to assess the health of some of the 52 fish stocks they survey, from the waters off North Carolina to the eastern reaches of the Gulf of Maine.

Fish migrate and change their feeding patterns as waters warm, which might make it difficult for National Oceanic and Atmospheric Administration scientists to compare this spring’s survey of fish populations with previous counts.

The prospect of skewed data could complicate efforts for policy makers to set proper quotas, potentially leading either to overfishing or unnecessarily strict catch limits.

“I worry that this will create statistical noise and more uncertainty,” said Gary Shepherd, a fishery biologist at NOAA’s Northeast Fisheries Science Center in Woods Hole, where he and other scientists recommend quotas based on what the Bigelow catches, along with other data.

As the waters warm, some of the fish, such as herring, migrate out of the survey area and into the region’s rivers. Other species, such as squid, which are short-lived, might not survive in representative numbers through June, when the Bigelow is now scheduled to finish its survey.

“If the survey had started at its normal time, it would have found squid on the continental shelf,” said Robert Vanasse, executive director of Saving Seafood, a Washington-based group that represents the fishing industry. “But now it won’t because the survey doesn’t sample Nantucket Sound.”

NOAA Research Vessel Now Homeported in Newport

April 13, 2016 — NEWPORT, RI — Today marks the first day that the 209-foot research vessel Henry B. Bigelow is officially homeported here in Newport, marking a “victory for the Ocean State,” according to U.S. Sen. Jack Reed.

The National Oceanic and Atmospheric Association fisheries research vessel has a primary objective of studying and monitoring Northeast Marine Fisheries throughout New England and has nets that trawl as deep as 6,000 feet.

The Bigelow collects data used for stock assessments that ultimately influences catch limits and fishing quotas as well as help scientists understand changes to the fishery.

Reed said that he has been lobbying for years for the ship to be homeported here in Rhode Island to save taxpayers money.

NOAA officials said that change is based on a study that included another vessel, the Okeanos Explorer, a deep sea exploration ship homeported at Quonset Point at the Port of Davisville in North Kingstown.
