MAINE: Maritime Shorts: Ghost gear, Marine Patrol, road map plans

August 18, 2021 — A study in southwest Nova Scotia estimated that abandoned, lost and discarded fishing gear, also known as ghost gear, account for more than $175,000 Canadian dollars in commercial losses annually.  

A team of researchers conducted 60 trips to retrieve the gear in one of Canada’s most productive lobster fishing regions and removed 7,064 kilograms of ghost gear – two-thirds of which were lobster traps. Those traps continued to capture species and the scientists found 239 lobsters and seven groundfish in the study. Buoys, rope and dragger cable were also retrieved and were either disposed of or repurposed. 

Most of the traps were believed to be less than 4 years old, though the oldest found was from 1987. Based on their markings, some of the debris likely originated from the U.S., likely traveling northward from the southern Gulf of Maine, according to the study. Tires, party balloons and a fan belt were also recovered.  

“While fishers often attempt to retrieve gear when it becomes lost during the fishing season, regular retrieval is challenging due to regulatory requirements, relocation issues, and lack of resources,” the study published in Marine Pollution Bulletin last month read. “Thus, allowing (abandoned, lost and discarded fishing gear) to persist, potentially continues to indiscriminately catch commercially valuable lobsters and other species and contributes to the growing problem of marine debris.”

How ‘ghost’ fishing gear affects at-risk species and fisheries’ bottom line

August 5, 2021 — Southwest Nova Scotia is one of Canada’s most productive lobster fishing region, spanning more than 21,000 square kilometers and contributing a significant portion of the country’s lobster supply.

With a busy fishery, though, has come the growing challenge of abandoned, lost and discarded fishing gear (ALDFG)—a collection of traps, ropes, hooks, cables and other fishing-related equipment that drift through the water column or litter the ocean floor. It is a global problem, but one that hasn’t been widely quantified.

Researchers at Dalhousie University wanted to find out how much gear might be in the Southwest Nova Scotia (SWNS) fishing zone and how it might be affecting the existing fishery. Their recently published baseline study provides the first preliminary assessment of environmental and economic impacts of ALDFG on the commercial lobster industry in the area.

Two endangered right whales entangled in fishing gear in Gulf of St. Lawrence

July 14, 2021 — A New Brunswick-based whale-rescue team says two North Atlantic right whales in the Gulf of St. Lawrence are entangled in fishing gear, a dangerous situation experts say risks killing the endangered animals.

Mackie Greene, director of the Campobello Whale Rescue program, said Wednesday the group tried last week to free Snow Cone, a female who had been originally spotted entangled off Cape Cod, Mass., last spring. Greene said an American crew removed some of the rope at the time but had to call off their efforts because of bad weather, adding that the whale continued north into Canadian waters.

“She was spotted in May in the Gulf and we responded and were able to get 30 feet of rope off of the whale, but she still has rope wound in her mouth, in her baleen and some trailing lines,” he said.

Greene said his team was able to remove three pieces of rope last week, adding that the animal appears healthy and is feeding; however, he said, more rope needs to be removed. “Snow Cone has a pretty sad story,” Greene said. “She’s a female, born in 2005. The year before last she had a calf and was coming north and the calf was run down and killed.”

He says a larger, mature whale that’s also entangled in gear has been spotted about 80 kilometres northeast of Shippagan, N.B., in an area where all the right whales appear to be congregated. Unlike Snow Cone, Greene said it appears the whale likely became entangled in the Gulf — perhaps the result of fishing gear that had been lost.

Norway salmon farming moves to cleaner waters: indoors

July 2, 2021 — Hundreds of thousands of salmon swim against the current in southeast Norway—in massive indoor tanks away from the nearest river as the controversial industry increasingly embraces greener land-based facilities.

The fish live in two gigantic pools inside an inconspicuous industrial building in Fredrikstad owned by a company that plans to raise salmon in similar settings even further afield, in the United States.

By raising the salmon on land, the industry is attempting to move away from the river or sea cages that have invited criticism over a slew of issues.

The problems run from costly mass escapes to fish infected with sea lice treated with chemicals to mounds of faeces and feed piling up on the seabed below the farms.

“At sea, you depend on the almighty for many things. In a land-based farm, we are suddenly the all-powerful one,” Fredrikstad Seafoods general manager Roger Fredriksen told AFP.

MAINE: This father and son traveled through rough seas to keep a family fishing tradition alive

June 14, 2021 — Like a lot of things on the old boat, the starter was beat up and broken.

To get underway, Nick Nieuwkerk connected the electrical terminals with the metal end of a screwdriver. Then, with a zap and spark, the ancient Detroit Diesel engine roared to life.

But then the throttle wouldn’t stay put, so Nick’s father, Knoep Nieuwkerk, rigged it open with a spoon and piece of string. Eventually, the pair were steaming out of Woods Harbor, Nova Scotia, on their way to Portland on April 7, aboard a 44-foot fishing boat that had seen better days since it first hit the water, 42 years earlier.

There was no guarantee they’d make it, but they had to try.

A U.S.-Funded Study Of Whales’ Hearing Is Going Ahead Despite Concerns For The Whales

June 9, 2021 — An international team of scientists is preparing to trap a dozen baleen whales off the coast of Norway and conduct hearing tests on them to gauge their sensitivity to human-made sounds such as sonar.

Researchers have tested the auditory faculties of smaller animals in captivity, but this would be the first time scientists have ever captured live whales in the wild to assess their hearing.

“This has been a long-standing issue, this lack of information on how sensitive the hearing of these large whales is,” said the project’s principal investigator Dorian Houser, of the National Marine Mammal Foundation.

“We’re trying to get the first measurements to empirically show what they hear and how sensitive to sound they are,” he said.

The goal of the project, which was initiated and is partly funded by the U.S. government, is to use what they learn to regulate human-generated noise in the waters where these whales swim. It could have implications for the military as well energy companies.

Salmon Group scraps plans for grasshopper feed produced by startup Metapod

May 19, 2021 — Bergen, Norway-based Salmon Group has announced it has scrapped its deal with Metapod to develop a locally-produced protein source featuring insects.

Under the original agreement, Metapod was going to produce insect flour from grasshoppers and crickets, to be used in the Salmon Group’s network of salmon and trout farms. The process was also going to use refined food waste, with an overall goal – Salmon Group said when the deal was announced last year – of reducing the company’s carbon footprint.

Seafood industry angered by UK-Norway fisheries deal collapse

May 3, 2021 — The bilateral fisheries agreement negotiations between Norway and the United Kingdom that ended with no deal reached between the two nations on Thursday, 29 April has sparked uproar in the regional seafood industry.

While both sides said that they worked hard to secure a deal, the countries said their positions continued to be too far apart to reach an agreement for 2021. Talks had been ongoing since January.

Cleaner fish from salmon farming affect wild populations

April 21, 2021 — A growing demand for cleaner fish in salmon farms raises concerns about overfishing and human-mediated geneflow to wild populations. A recent study reveals that up to 20 percent of the local populations of corkwing wrasse in mid Norway may constitute escapees and hybrids.

Every year, millions of wrasses are caught along the Swedish and Norwegian coasts, and transported to salmon farms for parasite control. Effects on the wild harvested populations, and the risks from cleaner fish escaping the farms, are poorly investigated.

Two recently published studies take a closer look at how the current fishery is affecting source populations and ecosystems, and to what degree translocated fish are escaping and mixing with populations outside the fish farms.
