Feds enforcing fishery, distancing rules to protect southern resident orcas

April 15, 2021 — For a third year in a row, the federal government has ordered fishery closures and imposed limits on vessel movements to protect the critically endangered southern resident killer whale population.

The measures by the Department of Fisheries and Oceans focus on the main threats to the orcas: lack of access to Chinook salmon stocks, acoustic and physical disturbance, and contaminants.

The commercial and recreational salmon fishery will be closed in a portion of Swiftsure Bank from July 16 to Oct. 31, and in Juan de Fuca Strait from Aug. 1 to Oct. 31.

DFO is also enforcing a new closure for commercial and recreational salmon fisheries in the southern Gulf Islands, where closures will be triggered by the first confirmed presence of southern resident killer whales in the area.

Monitoring will begin in the area on June 1. If a southern resident killer whale sighting is confirmed, the fishery will be shut down and remain closed until Oct. 31, the department said.

Distancing measures will also be enforced. For a second year, vessels will be prohibited from coming within 400 metres of any orca in coastal waters between Campbell River and Ucluelet, including Barkley and Howe Sound. This is in effect year-round until May 31, 2022.

Alaska Files to Defend Salmon Fisheries in Southeast Alaska

March 17, 2021 — The State of Alaska has moved to intervene in a federal case that threatens state management of Alaska’s salmon fisheries.

The Wild Fish Conservancy, a conservation organization based in Washington state, claims that Alaska’s management of fisheries under the Pacific Salmon Treaty threatens the survival of several salmon stocks in Washington and Oregon, and the endangered Southern Resident Killer Whales that depend on them.

The lawsuit seeks to shut down all salmon fisheries in the federal waters off the coast of Southeast Alaska.

Salmon Conservation Key to Saving Killer Whales

March 4, 2021 — The endangered Southern Resident killer whales in the waters near Washington and British Columbia have stalled in their population recovery, and, according to new research, a major factor limiting their growth is their preference for preying on Chinook salmon.

In a study published Wednesday in the journal PLOS One, researchers present new data on environmental stressors facing the orcas and propose investment in the conservation of Chinook salmon to aid in the recovery of the population.

Killer whales are some of the most recognizable mammals in our seas with their distinct black and white markings. While they can be found in every ocean, they have broken off into small populations, creating different sub-species known as transient, offshore, and resident. The three groups are unique to one another, with different physical attributes as well as social structures and behavioral habits.

There are multiple populations of resident killer whales, but the authors of this study looked specifically at Southern Resident killer whales. These orcas mostly inhabit the waters around Oregon, Washington and British Columbia, and make up the smallest of the resident populations.

Nearby Vessels Interrupt Feeding of Southern Resident Killer Whales, Especially Females

January 13, 2021 — The following was released by NOAA Fisheries:

Boat traffic within 400 yards of endangered Southern Resident killer whales interrupts their foraging, often leading female whales to cease feeding altogether. That is a key finding from a new analysis of data from suction-cup tags that track the whales’ movement underwater.

Previous research observed surface behavior of the killer whales in response to vessels, while the tags allow researchers to discern their behavior during extended dives underwater. This data shows that nearby vessel traffic inhibits their underwater foraging as much or more than what scientists previously documented at the surface. These new results were published in Frontiers in Marine Science.

“We found a bigger effect in females, and that effect was more often that they gave up foraging if vessels encroached on them,” said research scientist Marla Holt at NOAA Fisheries’ Northwest Fisheries Science Center. The analysis examined whale behavior over 3 years. It included years before and after the 2011 enactment of federal regulations limiting how close vessels can approach killer whales in Washington’s inland waters.

The outsize effect of vessel traffic on female whales “could have cascading effects on the ability to meet energetic requirements to support reproductive efforts,” the scientists reported. “This is particularly concerning in an endangered population that is in decline.”

PFMC Adopts Salmon Measures to Help Southern Resident Killer Whales

November 25, 2020 — The Pacific Fishery Management Council unanimously adopted new ocean salmon fishing regulations last week to help save critically endangered Southern Resident killer whales from extinction. While the birth of two calves this year was welcome news, Southern Residents face an uncertain future with only 74 individuals left and a diet almost entirely comprised of declining salmon populations, especially Chinook salmon, Oceana said in a press release.

Pacific salmon, primarily Chinook salmon, are 99 percent of the diet of Southern Resident killer whales. A single adult Southern Resident typically needs to eat 12 to 20 Chinook salmon every day, and as many as 30 depending on the size and nutrition levels of the fish. Wild salmon populations have been in decline due to a combination of issues, including dams, habitat loss and fishing pressure, Oceana said.

WASHINGTON: Navy, state clash over increased testing that could harm whales, marine life

September 2, 2020 — Navy and state leaders are at odds over a proposed rule for military testing in Puget Sound and coastal waters of Washington that allows the increased potential to harass and harm marine life, including the endangered and fragile Southern Resident orca population.

The Navy, in seeking approval from the National Marine Fisheries Service, is seeking to conduct testing and training involving a number of activities — firing torpedoes and projectiles, detonating bombs up to 1,000 pounds, using underwater sonar, piloting undersea drones and more. A proposed new rule would allow for the potential “take” — a term meaning “to harass, hunt, capture, or kill, or attempt to harass, hunt, capture, or kill any marine mammal” — of Southern Resident orcas from twice a year to up to 51 times, though federal officials say no conditions that could injure one of the 73 known remaining southern residents would be allowed.

On Friday, the state’s Department of Ecology pushed back with demands to constrict the Navy’s testing, including increasing the whale buffer zones to at least 1,000 yards and ceasing sonar exercises when orcas are spotted. The agency also asked for the Navy to use real-time whale alert systems like those used by the Washington State Ferries.

Fishery Council Seeks Input on Protecting Prey for Endangered Killer Whales

August 28, 2020 — The following was released by NOAA Fisheries:

A workgroup has outlined options for providing for prey needs of endangered Southern Resident killer whales in the course of designing West Coast salmon fishing seasons.

The workgroup was formed by the Pacific Fishery Management Council. Now the Council wants to know what you think of their options, described in a Range of Alternatives (PDF, 18 pages) and Recommendations. The options are available for public comment until September 2, 2020.

The options are varied and extend across the West Coast.

One alternative would be to set a threshold for salmon abundance. Under this alternative, if Chinook salmon numbers off the West Coast fall to a certain level, then additional management measures would apply to fishing. NOAA Fisheries identified a similar interim threshold to evaluate 2020 fisheries, although salmon numbers did not fall to that level.

Another option suggests updating the goals for how many Chinook salmon return to California rivers, such as the Sacramento River and the Klamath rivers. The anticipated removal of dams from the Klamath River could increase its potential for salmon production, according to the alternatives.

The Council will take public comments and consider the choices during its September meeting before refining a range of alternatives to share for broader input. The Council will then take public comment on those alternatives before finalizing its selection at its November meeting. Ultimately, NOAA Fisheries will evaluate and decide whether to approve the Council’s recommendation for the fishery measures under the Magnuson-Stevens Act. We will also ensure it complies with the Endangered Species Act.

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.

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.
