What is Nearshore Habitat and Why Does it Matter to Orcas?

June 23, 2020 — The following was released by NOAA Fisheries:

There is an especially valuable environment in Puget Sound made up of the beaches, bluffs, inlets, and river deltas: the nearshore. Nearshore habitat matters to Southern Resident killer whales because their primary prey, Chinook salmon, need them to grow and find safety when they are young. Unfortunately, we have been losing these habitats in Puget Sound to industrial and residential development and agriculture.

Southern Resident Killer Whales eat salmon, primarily Chinook salmon. The whales search out and rely upon the ever-changing abundance of many different Chinook salmon runs up and down the Pacific Coast. Puget Sound Chinook salmon are one of the most important of these for the Southern Residents’ recovery. Puget Sound Chinook salmon, however, are themselves threatened with extinction.

Killer whales eat Chinook salmon when the fish have grown into adults three years old and weighing close to 30 pounds. The salmon are headed back from the ocean through Puget Sound to their home rivers to lay their eggs. To make it to adulthood, though, these fish need to survive their adolescence as “juveniles” or “fry.” That’s where the nearshore zone comes in.

Tiny young Chinook salmon emerge from the gravel where they hatched from eggs in the rivers of Puget Sound and the Salish Sea—the Skagit, Elwha, Nisqually, and others. Then the young fish follow one of several different strategies to grow as juveniles before heading out to the ocean. They can rear in the river and freshwater floodplains or head downstream to the great tidal river deltas. They can also head all the way out into Puget Sound looking for safety along the shore in pocket estuaries, kelp and eelgrass beds, coastal creeks, or lagoons.

MAINE: Green Plate Special: Eat more lobster — this is the kind of ask we really like

June 22, 2020 — Maine’s iconic lobster industry has taken its share of lumps in the past year. Stricter 2019 quotas on the herring catch drove bait prices up. A cold 2019 spring meant the bugs molted later than usual, delaying when lobstermen could bring popular soft-shell lobsters (sometimes sold as “new-shell”) to market. On Sept. 1, China raised tariffs on live, American-caught lobster by 10 percent. And throughout the winter, scientists, environmentalists and the courts demanded the lobster fishery change to better protect endangered right whales  (the population hovers at just 400). The overall lobster haul dipped by 16% between 2018 and 2019, although harvesters were buoyed to some extent by higher than normal prices.

Yarmouth resident Rebecca Spear — wife, daughter-in-law and mother of lobster fishermen — explains that when the COVID-19 crisis first hit Maine in March, she didn’t immediately panic over how the pandemic might affect the 2020 income of the lobstermen and boys in her life (her 10-year-old son, Jack, holds a student lobster and crab license). “That’s always the slow season for us,” Spear said.

But as restaurant service in Maine and across the country remains truncated leading into prime lobster-eating season, she is worried now. Selling direct to customers was a good springtime stopgap solution. Spear is grateful that Maine eaters have sought out more locally sourced food as the national food supply has struggled in response to the pandemic. She urges Mainers to continue to buy lobster early and often this summer to help keep the fleet afloat. Here’s my suggestion: buy a few extra, cook them all for dinner, and serve the leftovers with eggs for breakfast.

Pew petitions for vertical-line fishing closures off New England “to protect right whales”

June 18, 2020 — The Pew Charitable Trusts submitted a petition for rulemarking to U.S. Commerce Secretary Wilbur Ross on 18 June urging him to take immediate action “to protect North Atlantic right whales from entanglement in federal waters off of New England.”

In a letter to Ross, Pew proposed a series of fisheries closures it says are “designed to afford the greatest protections for right whales, while minimizing the impact on fishermen.” The organization identified four areas off of New England where fisheries employ high-risk gear – such as lobster and crab traps with thick vertical ropes – and suggested that Ross designate closures during times when right whales are likely to be present.

Sound Strategy: Hunting with the Southern Residents, Part 1

June 15, 2020 — The following was released by NOAA Fisheries:

This is the time of year when boats multiply on the inland waters of Washington as more people get outdoors for the summer. It is also the time when many long for a precious chance to see the endangered Southern Resident killer whales.

Boats generate noise, though, which—combined with the boat traffic itself—is considered one of the main threats to the Southern Residents. It can interfere with the whales’ use of echolocation, a form of sonar they use to find the Chinook salmon they favor as prey. Regardless of how many salmon might be available, noise can make it harder for the whales to find them.

That can be particularly costly for the Southern Residents because salmon do not gather in schools as some fish do. The whales must find each one individually—painstakingly hunting one fish at a time.

National Report on Large Whale Entanglements Confirmed in the United States in 2018

June 11, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries has released a National Report on Large Whale Entanglements Confirmed in the United States in 2018. Many large whale populations are increasing in the United States, but entanglements in fishing gear or marine debris are a growing threat to the continued welfare and recovery of these species. Severe entanglements can kill or seriously injure large whales. Entanglements involving threatened or endangered species can have significant negative impacts to the population as a whole.

NOAA Fisheries coordinates the Marine Mammal Health and Stranding Response Program, which includes partners in the Large Whale Entanglement Response Network. They help us track and document as many of these incidents as possible. Entanglements represent a serious human-caused threat to large whales at the individual and population levels. Scientists and managers analyze entanglement data to determine:

  • Rates and severity of entanglements
  • Type of gear or debris causing the entanglement
  • Injuries and impact to the animal

Managers use that information to evaluate existing conservation measures and implement new ones as warranted to reduce the threat of entanglements in the future.

There were 105 confirmed entanglement cases nationally in 2018. This was above the 11-year average (70.8 + 21.8) and more than 25 percent higher than the number of cases in 2017. Some of the entanglements involved North Atlantic right whales on the East Coast, which could impede recovery of that critically endangered species. The National Large Whale Entanglement Response Network responded to 37 of 92 cases involving entangled live whales and successfully removed entangling gear from 16 whales. This increased their chances of survival as well as collected important documentation.

Maine Looking for New Ways to Save Whales From Fishing Gear

June 3, 2020 — Maine is in the final year of funding for a project that seeks to better protect endangered whales in the Gulf of Maine from entanglement in fishing gear.

The Maine Department of Marine Resources is using the project to collect data about vertical line fishing in the gulf, and develop a model to determine the fishing industry’s current use of the lines. The department is also hoping to use the model to predict the conservation benefits of new proposed regulations.

The state is slated to receive more than $200,000 in federal funds for the project this fiscal year, bringing the total federal money it has received to more than $700,000, the National Oceanic and Atmospheric Administration said in a statement.

Less Effort, More Lobster? New Research Suggests That Fewer Traps Can Still Yield Profitable Results

June 1, 2020 — New research suggests that the U.S. lobster industry could place fewer traps in the water and still gain just as much profit. And that finding could play a role in the debate over what should be required of Maine lobstermen to reduce entanglements with endangered North Atlantic right whales.

The study was published this week in the peer-reviewed Marine Policy Journal. Lead researcher Hannah Myers is a graduate student at the University of Alaska’s College of Fisheries and Ocean Studies. She took a close look at landings and other data from lobster-fishing territory that crosses the international Hague Line between Nova Scotia and Maine.

“We found that Canadian fishers in the Gulf of Maine caught about the same amount of lobster using seven and a half times less effort than Maine fishers on the U.S. side,” she says.

The researchers found that while the Canadians spent fewer days at sea and fished fewer traps, the traps they pulled had almost four times as many lobsters in them.

Lobstermen don’t need all the traps they use, research claims

May 29, 2020 — New research suggests that the U.S. lobster industry could place fewer traps in the water and still gain just as much profit. And that finding could play a role in the debate over what should be required of Maine lobstermen to reduce entanglements with endangered North Atlantic right whales.

The study was published this week in the peer-reviewed Marine Policy Journal. Lead researcher Hannah Myers, a graduate student at the University of Alaska’s College of Fisheries and Ocean Studies, examined landings and other data from lobster-fishing territory that crosses the international Hague Line between Nova Scotia and Maine.

Myers’ research might help to end an impasse between animal-rights activists who are looking to reduce entanglements injurious, if not fatal, to the whales and have said that Maine fishing lines are at least a statistically-significant threat to the creatures. Maine lobstermen criticize activists and researchers as advancing poorly-researched and economically damaging arguments to their way of life. A plan recently advanced by Maine fishermen was criticized by researchers as not going far enough, while Maine’s federal and state government leaders have called on the federal government to back down on encroaching upon Maine lobstermen.

Researchers Probe Orca Poop for Microplastics: Part 2

May 21, 2020 — The following was released by NOAA Fisheries:

How do microplastics end up in killer whale feces?

“There are two ways that the whales could ingest microplastics,” says Kim Parsons, Research Geneticist with NOAA Fisheries’ Northwest Fisheries Science Center. “They could incidentally swallow particles in sea water while eating fish, or they could ingest salmon that are themselves contaminated with microplastic particles.”

She suspects that most of the microplastics in orca poop are coming from the whales’ prey. The particles are traveling up the food chain from gut to gut, from herring to salmon to orca.

But why does it matter for orcas if their guts are full of microplastic particles and fibers?

How ingestion of microplastics affects marine mammals is both poorly understood and scientifically controversial. So the answer is, we don’t know yet, but scientists are concerned for the health of organisms at all levels of the marine food chain.

You might own a reusable water bottle advertised as being free of toxic chemical additives like bisphenol A, or BPA. Many chemicals found in microplastics are pollutants, such as polyethylene, polypropylene, phthalates, and BPA and its substitutes. Some of these chemicals are known endocrine disruptors, which means that the chemicals can disrupt an animal’s natural hormones. The chemicals may affect reproduction, growth and development, and ultimately population viability. When microplastics are moving through the whales’ digestive tract, the harmful chemicals could leach into their bodies.
