Saving Seafood

Strange visitor from the South (a manatee) is spotted off Cape Cod

August 30, 2016 — To the thousands upon thousands of seals that populate isolated beaches, and the frenzy of great white sharks that have frightened swimmers, now add another creature of the sea: an oddly graceful, roughly 8-foot-long manatee that has probably arrived from Florida to join the throngs of tourists enjoying the warm waters off Cape Cod.

Since mid-August, wildlife experts have documented at least a half-dozen sightings of the transient manatee they believe slowly swam up the East Coast to feed on local vegetation.

He or she still appears intent on taking in popular spots along the Cape, like any vacationer. The issue it faces is one of time: When the water temperatures drop, its chances of survival do, too.

Bill Pouliot and his son, Brayden, saw the wayward manatee while fishing on Bridge Street in Chatham Sunday. When the buoyant gray object came into view, they couldn’t believe its size.

“It was gi-normous,” said the elder Pouliot, mashing together the words “giant” and “enormous” to best describe the girth of the unexpected guest.

At first, both father and son thought the rotund animal spotted foraging on sea grass was a seal that wandered off from its beachy haunts.

But as they further examined the marine creature lazily floating nearby, they concluded it was something else entirely.

“It was just sort of going down to the bottom to eat, and then coming back up, perhaps sunbathing,” Pouliot said.

Study predicts alarming krill drop by end of the century

August 30, 2016 — Antarctic krill (Euphausia superba) habitat is undergoing a continuous deterioration process, which could lead to a reduction of up to 80 per cent by the end of the century.

Given the key role that this small crustacean plays in the marine food chain, its decline would cause other problems for species that depend on it as a food source, such as whales, penguins, seals, squid and fish, among other marine organisms.

This dark forecast comes from a study performed at Yale University by Andrea Piñones, a researcher at the Research Centre for High Latitude Marine Ecosystem Dynamics (IDEAL) and the Advanced Study Centre in Arid Zones (CEAZA), along with Alexey Fedorov, a researcher at Yale University.

Piñoness explains that the krill population has already fallen between 80 and 90 per cent since 1970, a situation that has generated a broad scientific debate on the causes of this decline.

In this regard, many believe that this is related to the changes in the environment, particularly with warming Antarctic waters.

To carry out the study, whose results were published in the journal Geophysical Research Letters, the researchers combined climate simulations — based on the projections of the international panel of climate change –, with a krill growth model. Thus, they determined that with an increase in water temperature and sea ice melting, its habitat could reduce up to 80 per cent by 2100.

Cutback mulled for herring catch

June 23, 2016 — PORTLAND, Maine — Federal regulators are considering a slight cut to commercial fishermen’s catch limit for Atlantic herring, a fish that is important both to the industry and the ocean’s food web.

The small fish gather in schools that can number in the millions, and are a critical food source for bigger fish, seals and whales. They also are important to humans as food and bait.

The National Marine Fisheries Service might reduce the herring catch limit by about 3 percent to slightly less than 105,000 metric tons. The limit was a little less than 108,000 metric tons for the 2013 to 2015 period; any new limit would apply to the years 2016 to 2018.

The proposal is up for public comment until July 21.

Scientists turn to drones to count growing seal colonies

March 7, 2016 — On a remote island off of Nantucket, scientists are using a tool most commonly associated with war and surveillance to get a look at fuzzy baby seals.

Researchers who want to get a handle on the growth of New England’s gray seal population have been using drones as part of an effort to photograph the animals, which gather in huge numbers on remote islands.

The National Oceanic and Atmospheric Administration used a pair of unmanned aircraft on Muskeget Island off of Massachusetts to take pictures of seal pups in January. The island is the biggest gray seal breeding colony in the country.

The pictures will help scientists find how many gray seals there are in Northeastern waters, said Kimberly Murray, the coordinator of the seal research program at NOAA’s Northeast Fisheries Science Center.

“We need to know how many seals there are before we can know what’s going on, and how to manage them. Or, I should say, manage us,” Murray said.

Climate change hurting New England cod population, study says

October 29, 2015 — The rapid warming of the waters off New England has contributed to the historic collapse of the region’s cod population and has hampered its ability to rebound, according to a study that for the first time links climate change to the iconic species’ plummeting numbers.

Between 2004 and 2013, the mean surface temperature of the Gulf of Maine — extending from Cape Cod to Cape Sable in Nova Scotia — rose a remarkable 4 degrees, which the researchers attributed to shifts in the ocean currents caused by global warming.

The study, which was released Thursday by the journal Science, offers the latest evidence of climate change — this time, affecting a species once so plentiful that fishermen used to joke that they could walk across the Atlantic on the backs of cod.

Fisheries management officials have sharply limited cod fishing in hopes of protecting the species, but they estimate the number of cod remain at as little as 3 percent of what would sustain a healthy population. The limits, in turn, have hurt fishermen.

“Managers [of the fishery] kept reducing quotas, but the cod population kept declining,” said Andrew Pershing, the study’s lead author and chief scientific officer of the Gulf of Maine Research Institute in Portland. “It turns out that warming waters were making the Gulf of Maine less hospitable for cod, and the management response was too slow to keep up with the changes.”

The institute had reported last year that the rise in temperatures in the Gulf of Maine exceeded those found in 99 percent of the world’s other large bodies of saltwater. The authors of Thursday’s study link the rapid warming to a northward shift in the Gulf Stream and changes to other major currents in the Atlantic and Pacific oceans.

They say the warmer water coursing into the Gulf of Maine has reduced the number of new cod and led to fewer fish surviving into adulthood. Cod prefer cold water, which is why they have thrived for centuries off New England.

The precise causes for the reduced spawning are unclear, the researchers said, but they’re likely to include a decline in the availability of food for young cod, increased stress, and more hospitable conditions for predators. Cod larvae are View Story eaten by many species, including dogfish and herring; larger cod are preyed upon by seals, whose numbers have increased markedly in the region.

NOAA Awards $2.75 Million for Marine Mammal Rescue Efforts

September 10, 2015 — The following was released by NOAA:

Today, NOAA Fisheries announced the award of $2.75 million in grant funding to partner organizations in 16 states to respond to and rehabilitate stranded marine mammals and collect data on their health. The John H. Prescott Marine Mammal Rescue Assistance Grant Program provides funding to non-profit and for-profit organizations, academic institutions, and state agencies that are members of the National Marine Mammal Stranding Network.

“Prescott grants help our national marine stranding response teams continue to improve their techniques, and supports our efforts to establish links between the health of marine mammals, coastal communities and our coastal ecosystems,” said Dr. Teri Rowles, NOAA Fisheries lead marine mammal veterinarian and coordinator of the Marine Mammal Health and Stranding Response Program. “The money supports vital information needed to protect and conserve whales, dolphins, seals, and sea lions.”

“Prescott grants tie directly to NOAA Fisheries’ core mission, which includes the conservation, protection and recovery of protected marine resources, including whales, dolphins, seals and sea lions,” said Eileen Sobeck, assistant NOAA administrator for fisheries. “Helping our stranding partners do their jobs on the front lines of response and rehabilitation fits in perfectly with our goals.”

The Stranding Network is comprised of trained professionals and volunteers from more than 100 organizations that partner with NOAA Fisheries to investigate marine mammal strandings, rehabilitate animals, and assist with research on marine mammal health issues. NOAA Fisheries relies on its long-standing partnership with stranding network members to obtain the vital research about marine mammal health needed to develop effective conservation programs for marine mammal populations in the wild.

Since the Prescott Grant Program’s inception in 2001, NOAA Fisheries has awarded 518 Prescott grants to members of the National Marine Mammal Stranding Network, totaling more than $45.5 million. Over the years, Prescott grants have enabled members to improve operations, such as expanding response coverage, enhancing response capabilities and data collection, and improving rehabilitation of marine mammals.

Prescott Grants are made under Title IV of the Marine Mammal Protection Act, which authorizes NOAA Fisheries to fund eligible members of the National Marine Mammal Stranding Network through grants and cooperative agreements.
