April 7, 2020 — A study on how warming ocean water impacts the early life stages of lobster will bring together two undergraduate colleges, a premier research institution, and a state agency.
The University of New England applied for the $860,000 grant from the National Science Foundation (NSF) and intends to share it with Hood College in Maryland, Bigelow Laboratory for Ocean Sciences, and the Maine Department of Marine Resources.
April 2, 2020 — The Gulf of Maine is warming faster than 99% of the world’s oceans. And the trend may be having an impact on Maine’s most valuable commercial fishery, if temperature affects lobster larvae and their success in growing to adulthood, scientists say.
The University of New England in Biddeford, Bigelow Laboratory for Ocean Sciences in East Boothbay, the Maine Department of Marine Resources and Hood College in Frederick, Md., have received an $860,000 grant from the National Science Foundation to study that impact.
“We’ll be studying how temperature influences how larvae settle, where they settle and how successfully they settle,” Markus Frederich, a UNE marine science professor helping to lead the project, said in a news release Tuesday. “The findings of this project will help us make more specific predictions of how many lobsters there will be in the Gulf of Maine in the future.”
Maine’s lobster catch was valued at $485.4 million last year, when Maine lobster harvesters landed 100.7 million pounds. It was a 17% decline compared with 2018, but landings still topped the 100-million-pound mark for the ninth year in a row.
April 15, 2019 — Extreme weather events and changing ocean conditions are creating unpredictable outcomes for aquaculture. One area where research is offering some insight into what to expect, though, is the increasing incidences of disease.
Anyone who was in France in the summer of 2018 can attest to the searing temperatures that swept the country. From north to south, the nation experienced the second hottest summer since records began. Whilst children played in lakes and the sea to cool off, the shellfish producers of Étang de Thau could only watch as their oysters and mussels perished at the hands of malaïgue – a period of sustained high temperatures and little wind.
The ocean has always been a highly dynamic environment, with its ever-changing conditions presenting challenges to aquaculturalists. However, thanks to human-induced climate change and continuing carbon emissions, events like malaïgue may become more regular occurrences, bringing with them new disease-related challenges.
As every aquaculturalist knows, temperature plays a major role in the growth and health of aquatic species. Certainly, higher temperatures are typically related to higher energetic requirements and demand for food. In an interesting twist, finfish can find their hunger suppressed when held at the upper end of their thermal tolerance for too long – even though their metabolic demands continue to rise. Malnourished fish make for unhealthy fish, which makes for a more stressed and susceptible animal.
Temperature doesn’t just impact farmed animals. As work from Dr Tommy Leung, a parasitologist at the University of New England in Australia has shown, temperature also appears to have a relationship with the severity and duration of disease outbreaks. “If you are in a more temperate region, you might have an outbreak where half of your stock die whereas in the tropics you have over 90 percent dying,” Leung explained. To compound the problem, outbreaks in those warmer tropical and near-tropical regions also happen over a much shorter period. “This means you could have less time to respond to any potential outbreak.”
July 31, 2018 — SEAFOOD NEWS — NOAA Fisheries and the New England and Mid-Atlantic Fishery Management Councils have announced three new cooperative research projects that will improve the understanding of monkfish biology, as well as how to reduce catch of skates in monkfish gillnet gear. 500 days-at-sea have been set aside by the councils to be awarded to projects that address monkfish research priorities.
Coonamessett Farm Foundation was awarded 296 monkfish Research Set-Aside (RSA) days-at-sea to conduct a 2 years study on determining sex and maturity stage in Southern New England monkfish. Coonamessett Farm Foundation will use ultrasound methods to determine sex and maturity stage. In addition, they will also be conducting hormone analyses to “create a reproductive profile based on sex and maturity stage of monkfish.”
Meanwhile, Cornell University Cooperative Extension of Suffolk County was awarded 303 monkfish RSA days-at-sea to conduct a 2-year experiment evaluating a modified gillnet designed to reduce skate bycatch. The University of New England was awarded 401 monkfish RSA days-at-sea to conduct a 2-year study on monkfish vertebrae and illicia.

July 24, 2018 — Marine researchers have deployed underwater cameras in hopes of documenting great white sharks off the coast of southern Maine for the first time.
The effort is part of the first study dedicated to learning about the habits of the sharks near Maine. Scientists say great whites – the world’s largest predatory fish – have increased in number in the Atlantic Ocean and will continue to do so in the Gulf of Maine.
Two cameras, each attached to a crate of chum to attract large fish, were deployed by University of New England professor James Sulikowski and undergraduates two weeks ago near Stratton Island, 2 miles from Old Orchard Beach. The island was chosen because a radio receiver that Sulikowski placed on a nearby buoy detected a tagged great white shark last fall.
“The goal is to get a better understanding of the ecosystem and what white sharks are coming in, and to find out how prevalent they are,” said Sulikowski, a marine biologist.
A UNE professor joins Massachusetts researchers in examining patterns of a population likely to proliferate in the Gulf of Maine.
July 31, 2017 — Marine biologists are embarking on the first study dedicated to learning about the habits of great white sharks off the coast of southern Maine, where the scientists say the fishes’ population is likely to increase.
University of New England professor James Sulikowski will collaborate with Greg Skomal of the Massachusetts Division of Marine Fisheries to see how often the sharks come near the coast.
Great white sharks are the world’s largest predatory fish. Known for their powerful jaws and serrated teeth, they can grow to more than 20 feet and 4,000 pounds.
They have been protected from harvesting in U.S. waters since 1991. Skomal said the shark population has been rebounding since.
“We definitely believe the entire East Coast population is increasing and that we are likely to see white sharks in the Gulf of Maine increasing,” he said.
June 28, 2017 — During more than 25 years studying a variety of fish, including sharks, James Sulikowski has had to solve all kinds of problems. Among the trickiest and most important: How do you gather data about pregnant sharks without first killing them?
“The catch-22 is that you need the information to better manage them, but in order to get the information [you used to have to] kill them. You’re damned if you do, damned if you don’t,” Sulikowski, a professor at the University of New England in Biddeford, said. “So that’s where my sort of science came in. We treated sharks basically like pregnant females, like human beings. How are humans studied? Well, you take blood and you can look at that blood for circulating levels of hormones [to determine if the female is pregnant].”
That idea morphed into taking special waterproof, veterinary-grade ultrasound equipment onto boats and examining sharks that later would be released alive.
That kind of newly available data on shark reproduction made Sulikowski and his colleagues rock stars in the shark world and drew the interest of the Discovery Channel.
When Discovery Channel’s popular “Shark Week” franchise returns for another wall-to-wall dose of toothy adventure in July, Sulikowski and his colleagues will be prominently featured. That episode, titled “Shark Vortex,” will air at 8 p.m. on July 24.
Sulikowski was tight-lipped about what viewers will see during the episode, which marks the second straight year his work will have been featured during “Shark Week.” In 2016, “Tiger Beach” kicked off Shark Week and drew between 6 million and 7 million viewers during three airings, according to Sulikowski.
“[‘Shark Vortex’] is top secret. I signed my life away for that,” Sulikowski said. “But I can tell you it’s a great story. It’s basically sharks of New England, in a sense. It’s gonna have white sharks, it’s gonna have makos, it’s gonna have porbeagles. The ones that really separate us from other places.”
June 28, 2017 — Days after there was a reported shark sighting on Wells Beach, a University of New England shark expert tells beachgoers the chances of being attacked by a shark, particularly in Maine, are astronomically low.
Police cleared Wells Beach of swimmers Sunday afternoon, after a reported sighting of a shark. Wells Police Sgt. Adam Shaw said it was a precautionary measure, taken when someone reported seeing a 12-foot shark in the water between Wells Beach and North Beach. He said the harbormaster searched the area and found no signs of a shark.
The initial report came from a paddleboarder who said the shark was as long or longer than his 12-foot board. A second report came from an individual who thought it was a harmless basking shark.
Dr. James Sulikowski, professor of marine science at University of New England in Biddeford, said beachgoers globally are concerned about sharks – but that needs to be put in some perspective.
“One of the biggest concerns people have when they go to the beach is being attacked and eaten by a shark,” Sulikowski said. “But if you look at it globally, there are 100 to 150 shark attacks per year – that’s across the world. And if you put it in perspective with how many billions of people there are, the chances are astronomically low. And then to bring it into further perspective, there’s never been an unprovoked shark attack in Maine. Not one.”
Sulikowski, a global expert in the study of sharks, said basking sharks are more common in Maine waters, and are often confused with great white sharks. He said they often come much close to shore and they can be 25 to 30 feet long. They have big wide mouths and no teeth, and they feed on plankton and small fish, he said.
April 26, 2017 — A Portland real estate developer outbid the owners of Cook’s Lobster & Ale House on Tuesday to purchase the Bailey Island wharf adjacent to the restaurant for $510,000.
Arthur Girard, who in 2015 donated Ram Island in Saco Bay to the University of New England, said he’s not sure what he’ll do with the property, which for decades has operated as a commercial fishing wharf for local lobstermen.
“I have no plans for it,” he said. “That’s how I get inspired.”
Girard, who does business as AMG Holdings in Portland and Miami, Florida, was one of a handful of registered bidders who had provided a $50,000 deposit before Tuesday’s auction, held inside a building on the dock. In the end, only he and Cook’s Lobster owner Nick Charboneau volleyed to win the property.
Auctioneer Michael Carey of Tranzon Auction House in Portland started the bidding at $800,000 but with no takers quickly came down to $500,000 and then $400,000 — and within minutes was asking for a bid to best another at $300,000.
Among the three dozen people seeking shelter from the rain inside amid the lobster tanks, Carey paused the bidding twice, once for nearly 20 minutes, after which Charboneau increased his bid to $400,000.
Girard went to $475,000, and the two volleyed until Girard offered $510,000, at which point Charboneau was done.
June 24, 2016 — A UNE researcher known as ‘Dr. Shark’ develops a method that allows fish data collection without killing the specimens.
A decade ago, when James Sulikowski first came to the University of New England, scientists who studied shark reproduction had to kill and gut their specimens to unlock the secrets of how these elusive fish gave birth.
Sulikowski wanted to learn more about the reproductive process in hopes of bolstering shark numbers, and didn’t like the idea of having to kill pregnant sharks and their unborn young to do it. That study method also made it impossible to study the reproductive habits of endangered sharks, such as the basking, hammerhead or tiger shark, even though information about how these threatened groups lived and loved would have helped policymakers protect their mating or pupping grounds and possibly help stabilize their populations.
Scientists had begun using blood samples to supplement their shark necropsies, measuring hormone levels to establish the stage of pregnancy, but Sulikowski, a father of three, thought researchers could go further. About five years ago, he turned to the same kind of sonogram technology that doctors use to monitor pregnant women – complete with a transducer, an image screen and conductive jelly – and adapted it for use on pregnant sharks, as well as other elusive or endangered fish species, such as sturgeon.
“There is so much that we still don’t know, like where different species of sharks go to give birth,” Sulikowski said, “and so much that we think we do know, like the length of gestation for our local spiny dogfish that we are just now learning through the use of this technology and tagging that is just plain wrong. I love that. I love challenging accepted science. For me, it’s always about being inquisitive, testing what we think we know, asking what we don’t and figuring out new ways to come up with answers to questions we didn’t even know to ask just a few years ago.”
