White sharks make frequent visits to Maine's coastal waters, new data reveals
Apr. 7—Great white sharks appear to be using the shallow coastal waters next to some of Maine's most popular beaches in late summer while traveling between Cape Cod and Nova Scotia, most likely snacking on the growing seal populations in the Gulf of Maine. A team of New England scientists documented 107 white sharks off the coast of Maine, ranging from 7 to 16 feet in length, between 2012 and 2023, with most detected within a half mile from shore in less than 65 feet of water, according to a study published last month in Frontiers in Marine Science. But the total number of white sharks in Maine remains very low compared to known hotspots like Cape Cod or Hilton Head, according to the study's lead author, Matthew Davis of the Maine Department of Marine Resources. On average, Maine beaches had a tagged white nearby less than seven days a year. The relatively low numbers led the research team to conclude that Maine swimmers aren't at significant risk and, despite the documented presence of white sharks in the Gulf of Maine, there is no justification for regional anti-shark measures, like shark nets, even along Maine's most popular beaches. While most whites are not tagged and come and go without setting off the acoustic sensors, the data gives researchers a new picture of white shark prevalence and movements along the Maine coast. "We know a lot about white sharks in Cape Cod and Nova Scotia, but the Gulf of Maine has been sort of a black box of information up until now," Davis said. "This is the first time anyone has been able to track the movements of white sharks over time in the region." After a white shark killed a woman swimming off Bailey's Island in Harpswell in 2020 —Maine's only fatal shark attack on record — the Maine Department of Marine Resources launched a white shark study team and deployed acoustic sensors along the coast to track the activity of already-tagged white sharks. The department placed a sensor — think of them like a barcode reader with a big range — near sandy beaches, populated islands and seal haul-out sites, where the favored target of hungry adult white sharks are known to come ashore to rest, molt, breed and have pups. The sensors show white sharks like the same sandy beaches we do, including Ogunquit, Kennebunk, Higgins and Wells. In an average year, Ogunquit attracts seven tagged sharks over five days, compared to Kennebunk's six sharks in six days, Higgins' five sharks in five days and Wells' five sharks in four days. And many like to go when we do. Nearly half the sharks were detected near beaches visited during the daytime. Their numbers start to surge in June and drop off in October, preferring water that is between 55 and 60 degrees Fahrenheit, although some will stay through December. But it is important to note that the average shark detected near a Maine beach only hung out for about 15 minutes, Davis said. The average time spent out in the waters off Maine islands tended to be a little bit longer. In one rare case, a white shark hung out off the coast of Saco for more than a day. A private beach open to the public at the southwest tip of the Phippsburg peninsula — Head Beach — appears to be the most popular among white sharks, attracting 40 different whites over a three-year period, the study found. Sensors there detected an average of 17 sharks a year over 13 days. Surprisingly, nearby Popham only averaged three sharks a year, while Reid averaged only two. Ragged Island in eastern Casco Bay — notable as the one-time summer home of poet Edna St. Vincent Millay — reported the highest number of days of shark activity a year, with 12 sharks visiting over 30 days. Ragged is close to haul-out sites where seals come ashore to rest, breed and have pups. White sharks are not new to the Gulf of Maine, Davis said. Their numbers here are likely bouncing back because of conservation measures put in place for both white sharks, which were overfished until the 1990s, as well as seals, a favorite prey species for adult whites. Maine is located between three of the largest gray seal colonies in North America, with pupping surveys indicating a growing population in the region. Within the last decade, the harbor seal population has grown to more than 61,000. Like many of Maine's terrestrial visitors, white sharks tend to stick to southern and midcoast Maine locations. With one exception, no more than seven sharks were detected at any one Downeast location. Fewer acoustic receivers in these areas might help explain the relatively low detection rates. The sensors can detect a tagged shark up to 2,000 feet away. That means a tagged shark at some of Maine's longest beaches, like Ogunquit or Wells, could be missed. Most importantly, the study cannot paint a full picture of the white sharks in Maine because most of them aren't tagged at all. Davis said he would like to deploy more sensors in Downeast waters in the future. Copy the Story Link

Maine's Great White Sharks And What We Know So Far
New research reveals that over the past 13 years, more than 100 great white sharks have been ... More detected off Maine's coast, with the majority of sightings occurring in recent years and in relatively shallow waters. Over the past 13 years, great white sharks have increasingly made their presence known off Maine's coast. More than 100 individual sharks have been detected, with the majority of sightings occurring in recent years and notably in shallow waters. This shift in behavior has prompted researchers to dive deeper into understanding what these sharks are doing in Maine's waters, and their latest findings have just been published in Frontiers in Marine Science. The research is the result of collaboration between the Maine Department of Marine Resources, the Atlantic White Shark Conservancy, the Massachusetts Division of Marine Fisheries, and several other organizations. 'We are excited to have this study published and continue to expand our understanding of white sharks in the western North Atlantic and the coastal waters in Maine,' said Matt Davis, the lead author of the study and a scientist with the Maine Department of Marine Resources. 'This work could not have been done without the collaboration of many researchers and organizations, and we thank everyone involved.' This study is particularly significant because it marks the first time that researchers have been able to track the movements of white sharks over time in the region. The effort started in 2020, following a tragic event when a swimmer was killed by a white shark off the coast of Harpswell, marking Maine's first recorded fatal shark bite. In response to this incident, officials at the Maine DMR worked closely with other groups to expand the study of white sharks and their behavior in Maine's coastal waters. The team used an array of receivers placed along Maine's coastline, from York and Ogunquit to Kennebunk and Reid State Park. These receivers were designed to detect sharks that had been tagged off Cape Cod, Massachusetts, and Hilton Head, South Carolina. 'We are excited to have this study published and continue to expand our understanding of white ... More sharks in the western North Atlantic and the coastal waters in Maine,' said Matt Davis, the lead author of the study and a scientist with the Maine Department of Marine Resources. 'This work could not have been done without the collaboration of many researchers and organizations, and we thank everyone involved.' With the data collected over the years, researchers were able to develop a clearer picture of the sharks' movements and behavior patterns in the area. The findings show that these sharks are spending time in waters less than 50 meters (164 feet) deep off Maine, with peak sightings occurring between July and September; this aligns with previous observations of white sharks using similar habitats in other regions. But what stands out in this recent study is how often these sharks are detected during daylight hours. Half of the shark detections occurred during the day, a time when beaches are typically busy with human activity. This was particularly true along areas like Ogunquit, Kennebunk, and Head Beach in Phippsburg, which had some of the highest numbers of shark detections. Despite the uptick in shark sightings, the team also found that the frequency of white shark detections along Maine's beaches was still relatively low compared to other regions where these sharks are known to frequent. For example, areas off Cape Cod, which has long been known as a hotspot for white sharks, saw far more frequent detections. The team emphasized that while the presence of sharks in Maine waters is notable, there is no reason to believe that humans are at significant risk. While sharks are often feared, they are a vital part of the marine ecosystem, playing an important role in regulating the populations of other marine species. Their presence in Maine's waters suggests a healthy marine environment, which could be beneficial for the overall ecosystem. The scientists hope the findings of this study will help inform future management strategies in Maine. By understanding where and when white sharks are most likely to be detected, researchers and policymakers can better communicate with the public about how to safely enjoy Maine's beaches without unnecessary fear. As Maine continues to see more shark detections in its waters, studies like this will be crucial in ensuring that shark conservation efforts continue while also keeping human safety a priority.

U.S. lobster catch drops as crustaceans migrate to colder Canadian waters
The U.S. lobster industry's catch keeps sliding as fishermen contend with the northward migration of the valuable crustaceans. The industry is based mostly in Maine, where lobsters are both a cultural signifier and the backbone of the coastal economy. The state's haul of lobsters has declined every year from 2021, when it was nearly 50 million kilograms, to 2023, when it was less than 44 million kilograms. That decline extended into 2024, when the haul was about 39 million kilograms, according to data released by state regulators on Friday. That is the lowest figure in 15 years. A series of major storms that damaged waterfront communities and disrupted fisheries was a key factor in the reduced catch, officials said. Gov. Janet Mills, a Democrat, praised the industry for its perseverance. "During a year shaped by unprecedented storms and damage to our working waterfronts, Maine's commercial fishermen, aquaculturists, and seafood dealers once again delivered a major economic benefit to our state," she said. Last year's catch was still historically high, as Maine fishermen never exceeded 36 million kilograms prior to 2009. Hauls in the 2000s were typically between 23 million and 31 million kilograms. Hauls in the mid-2010s were routinely above 54 million kilograms. The fishery remained economically strong in 2024. Maine fishermen took home more than $528 million at the docks, and that was the highest total since 2021, state officials said. Demand for the product, one of the most expensive seafoods, remained high, and the price per pound was one of the highest on record. The state is meeting the challenges of climate change head-on, said Patrick Keliher, the commissioner of the Maine Department of Marine Resources. The governor has secured funding to "help rebuild damaged coastal infrastructure, make it more resilient to the effects of climate change, and protect critically important waterfront access for those who make a living on the water," he said. But numerous environmental and economic challenges threaten the industry's future. One of the biggest is the decline in the number of baby lobsters settling off New England. The young lobsters have to take shelter and grow to legal size to sustain the future of the fishery. Scientists have said the lobster population is migrating north to cooler habitats as oceans warm. The Maine lobster industry is also linked to Canada's seafood industry and could be disrupted by new tariffs. Canadian fishermen harvest the same species of lobster as American fishermen, and much of the processing capacity for the seafood is in Canada. Tariffs are likely to increase prices on both sides of the border, members of the industry have said. Another major challenge is the possibility of new rules to protect critically endangered North Atlantic right whales, which are vulnerable to entanglement in commercial fishing gear. Fishing groups have engaged in protracted court cases against the government over stricter fishing rules. Other states, including Massachusetts, Rhode Island and New Hampshire, also have lobster fishing industries, but Maine's is by far the largest, and the size of the Maine harvest gives a firm indication of the health of the American lobster industry at large. Maine accounted for about 78 per cent of the country's total lobster haul in 2023.

US lobster catch drops as crustaceans migrate to colder Canadian waters
SCARBOROUGH, Maine (AP) — The U.S. lobster industry's catch keeps sliding as fishermen contend with the northward migration of the valuable crustaceans. The industry is based mostly in Maine, where lobsters are both a cultural signifier and the backbone of the coastal economy. The state's haul of lobsters has declined every year from 2021, when it was nearly 111 million pounds, to 2023, when it was less than 97 million pounds. That decline extended into 2024, when the haul was about 86.1 million pounds, according to data released by state regulators on Friday. That is the lowest figure in 15 years. A series of major storms that damaged waterfront communities and disrupted fisheries was a key factor in the reduced catch, officials said. Gov. Janet Mills, a Democrat, praised the industry for its perseverance. 'During a year shaped by unprecedented storms and damage to our working waterfronts, Maine's commercial fishermen, aquaculturists, and seafood dealers once again delivered a major economic benefit to our state,' she said. Last year's catch was still historically high, as Maine fishermen never exceeded 80 million pounds prior to 2009. Hauls in the 2000s were typically between 50 million and 80 million pounds. Hauls in the mid-2010s were routinely above 120 million pounds. The fishery remained economically strong in 2024.
