MAINE: What Maine hopes to learn from its offshore wind research array

September 13, 2024 — Maine has big goals for adding offshore wind to its energy repertoire with hopes that it will not only be a friendlier option for the planet, but help revitalize communities through its economic and labor opportunities. But before those benefits can be realized, there are still a number of outstanding questions.

Last month, the state and the federal government reached an agreement on a lease for an offshore wind research array that will sit about 30 miles southeast of Portland. It will take up about 15 square miles in federal waters and include up to 12 floating turbines that will help inform how floating offshore wind operates and interacts with ecosystems in the water.

Just last week, the Federal Bureau of Ocean Energy Management released its final environmental assessment that showed leasing activities such as surveys and installing meteorological buoys in the Gulf of Maine won’t harm the surrounding environment.

And while that assessment did not look at the impact of the offshore turbines, the goal of the research array is to better understand how they will interact with the Gulf of Maine ecosystems.

“The only way we really can answer those questions is to have this type of a program and this kind of a unique in-water opportunity to actually answer those questions,” said Stephanie Watson, offshore wind program manager for the state.

Research has been a throughline of Maine’s offshore wind efforts, Watson said, especially when thinking about the pioneering research and development from the University of Maine for semi-submersible floating turbines.

The next step in that process is to understand how to responsibly deploy the budding industry and actually transmit the energy back to shore, all while reducing impacts to the fisheries that are vital to the economy and culture of Maine, Watson said.

American lobster show resilience amid climate change

September 12, 2024 — Experiments conducted at the Virginia Institute of Marine Science (VIMS) have shown that female American lobsters groom their offspring, and the grooming behaviors appear to remain stable despite the temperature and acidity conditions projected for Maine’s coastal waters by the end of the century. A study by researchers at William & Mary’s Batten School of Coastal & Marine Sciences shows that the species may be more resilient to the effects of climate change than previously thought.

The study examines how a changing climate may impact the reproductive success of species that brood or incubate and hatch their eggs. The findings were published in the journal Marine Ecology Progress Series and suggested that American lobsters can handle future ocean changes well, as their egg care and survival rates stayed stable under different conditions through the study’s tests.

Digging into the study

The study’s researchers partnered with the Maine Department of Marine Resources to obtain 24 lobsters from commercial operations for the study for five months. They secured female lobsters at market size with all legs intact, which are commonly lost in the wild.

MAINE: Maine instituting workforce development programs to tackle aquaculture labor shortages

September 11, 2024 — The U.S. state of Maine’s USD 137 million (EUR 124 million) aquaculture industry is attracting investment and creating new job opportunities, but filling those jobs as fast as they’re opening has become an issue.

The Maine Aquaculture Association estimates that based on current growth trends, aquaculture businesses statewide will be short 1,300 employees 15 years from now, making workforce development a crucial issue for the industry if it wants to expand as planned.

Study offers hope for the resilience of the American lobster fishery

September 11, 2024 — According to a study by researchers at William & Mary’s Batten School of Coastal & Marine Sciences, the American lobster may be more resilient to the effects of climate change than expected. For the first time, experiments performed at the Virginia Institute of Marine Science (VIMS) have documented how female American lobsters groom their offspring, providing evidence that these behaviors are not significantly impacted by temperature and acidity levels forecasted for Maine’s coastal waters by the end of the century.

The findings are published in the journal Marine Ecology Progress Series.

Despite being one of the largest commercial fisheries in the U.S. with an annual economic impact of more than $460 million in Maine alone, few studies have documented the reproductive  of female American lobsters. With the Gulf of Maine warming faster than nearly any other ocean surface on the planet, it’s important to understand how the effects of climate change will impact the sustainability of the species and the fishery it supports.

“Brood grooming by female lobsters has been anecdotally observed, but it had not been quantitatively recorded before,” said Abigail Sisti, who is completing her Ph.D. in Marine Science at the Batten School and is lead author on the study. “In other crustaceans, these behaviors can have a significant impact on the survival of their offspring. Because the environment supporting the lobster fishery is rapidly changing, we wanted to understand how it might impact the way they care for their offspring.”

Female American lobsters can produce thousands of eggs that they hold under their tails for long periods of time, between five to 12 months, as the embryos develop. In other crustaceans, grooming behaviors help clear out parasites, remove dead eggs and facilitate the flow of water carrying oxygen and nutrients through the densely packed egg masses.

The study was part of a larger effort to determine how multiple stressors affect the reproductive success of the species. In this study, the researchers were testing whether increases in  and acidity had an impact on grooming behaviors and embryo survival.

MAINE: Great Northern Salmon beginning pre-construction work on Maine-based salmon RAS

September 10, 2024 — Great Northern Salmon (GNS) announced it is commencing pre-construction work in preparation for its salmon recirculating aquaculture system (RAS) facility in Millinocket, Maine, U.S.A., in mid-September.

The company – formerly known as Katahdin Salmon – is a project of Xcelerate Aqua and is aiming to build a 10,000-metric-ton (MT) salmon RAS in two phases, with its first phase of construction capable of 5,000 MT, which can later be expanded. Great Northern Salmon plans to build the facility on the site of the former Great Northern Paper Co. mill, as part of the One North industrial site.

Opinion: Policymakers in search of sound science need to listen to fishery

September 9, 2024 — Fishermen are gravely concerned that regulators are stealing our futures with baseless cuts to landing quotas. Rep. Jared Golden is taking positive steps to fix this problem.

It often happens that government regulators, who lack deep knowledge of what it takes to catch fish in the Gulf of Maine, reach conclusions about the state of our fish stocks that do not match what fishermen are seeing and what we know from being on the water every day.

The obvious objection whenever we raise this concern is that “anecdote is not the plural of data.” The doubters ask: Why would an individual fisherman know more than a government agency with a dataset? That’s a fair question.

The answer is this – we know what tactics regulators are using to catch fish for their surveys, and we know they don’t work. We know where regulators are conducting surveys, and we know fish don’t hold in those waters. We know how extensive the surveys are, and we know they aren’t thorough enough.

Just how rare is a rare-colored lobster? Scientists say answer could be under the shell

September 9, 2024 — Orange, blue, calico, two-toned and … cotton-candy colored?

Those are all the hues of lobsters that have showed up in fishers’ traps, supermarket seafood tanks and scientists’ laboratories over the last year. The funky-colored crustaceans inspire headlines that trumpet their rarity, with particularly uncommon baby blue-tinted critters described by some as “cotton-candy colored” often estimated at 1 in 100 million.

A recent wave of these curious colored lobsters in Maine, New York, Colorado and beyond has scientists asking just how atypical the discolored arthropods really are. As is often the case in science, it’s complicated.

Lobsters’ color can vary due to genetic and dietary differences, and estimates about how rare certain colors are should be taken with a grain of salt, said Andrew Goode, lead administrative scientist for the American Lobster Settlement Index at the University of Maine. There is also no definitive source on the occurrence of lobster coloration abnormalities, scientists said.

“Anecdotally, they don’t taste any different either,” Goode said.

In the wild, lobsters typically have a mottled brown appearance, and they turn an orange-red color after they are boiled for eating. Lobsters can have color abnormalities due to mutation of genes that affect the proteins that bind to their shell pigments, Goode said.

US gives key OK for 15GW floating wind area in Gulf of Maine

September 6, 2024 — US regulator Bureau of Ocean Energy Management (BOEM) has approved its environmental assessment (EA) for a giant floating wind area in the Gulf of Maine holding some 15GW of potential capacity.

The EA authorises developers to carry out site assessment activities such as installation of meteorological buoys and surveys, a key step allowing a lease sale to go forward. Any projects planned for the region following the lease sale will need to undergo a more thorough environmental impact statement (EIS).

In Harpswell Sound, Bowdoin researchers are unlocking the secrets of a red tide hot spot

September 6, 2024 — Collin Roesler wants us to have a better understanding of the algae that cause red tides in Maine.

A professor in the Earth and Oceanographic Science Department at Bowdoin College, she studies phytoplankton, notably Alexandrium fundyense. This single-celled marine plant is the source of a neurotoxin that can contaminate shellfish such as mussels, clams and oysters. People who consume shellfish tainted by the toxin can experience paralytic shellfish poisoning, which can be fatal.

One of her current research projects is focused on Alexandrium in Harpswell Sound and in Lombos Hole, near the head of the sound. Her work is unlocking information that has implications for efforts to monitor and predict serious red tide events.
