NOAA Fisheries Joins Orca Action Month with Events Throughout June

June 7, 2021 — The following was released by NOAA Fisheries:

This month, NOAA Fisheries is helping orca fans everywhere learn about and help protect endangered Southern Resident killer whales (called orcas) and other killer whales in the Northwest. Join us for a month of interesting webinars, educational opportunities, and outdoor activities.

Washington Gov. Jay Inslee has again proclaimed June Orca Action Month, which is organized by Orca Network and the members of the Orca Salmon Alliance.

“This is a time to consider what Southern Residents mean to the Northwest, and the whole West Coast,” said Scott Rumsey, Deputy Regional Administrator of NOAA Fisheries West Coast Region. “We are fortunate to live in a place with these wild predators, and we have a responsibility to look out for them. Whether it’s reducing polluted stormwater by planting a rain garden, or saving energy by walking instead of driving, we all can contribute.”

Many events this year will be online, expanding their reach not only across the country but around the world. Whether you live in Puyallup or Paris, you can ask biologists questions about the latest orca science. You can also join in interactive exercises that will provide new insight in how our personal actions can contribute to orca recovery.

An in-person kick-off event on June 6 helps start the activities. They will include socially-distanced volunteer habitat restoration such as restoring stream habitat on Chico Creek in Kitsap County and at Bothell’s largest park, the former Wayne Golf Course. Weekend kayak tours will explore Elliott Bay and the Duwamish River with guest speakers explaining the threats facing Southern Resident orcas.

Limiting Chinook Fishing in Low-Return Years to Help Killer Whales: What Do You Think?

June 3, 2021 — The following was released by NOAA Fisheries:

NOAA Fisheries is asking for public input on a Pacific Fishery Management Council recommendation to reduce impacts from fishing off the West Coast. The recommendation would be implemented if salmon numbers fall too low to provide enough prey for the 75 endangered Southern Resident killer whales.

NOAA Fisheries is proposing to adopt the Council’s recommendation, and conducted a consultation under the Endangered Species Act. This consultation ensured that the amended fisheries management plan does not jeopardize the continued existence of threatened or endangered species, or negatively impact designated critical habitat. It incorporated recent research that revealed new details of when and where the whales forage, and their preferred prey.

The Council created a workgroup of representatives from West Coast states, tribes, and NOAA Fisheries to examine the issue. The workgroup completed a risk assessment evaluating the impact of fisheries on West Coast Chinook salmon abundance and, in turn, on the Southern Residents, and developed recommendations.

Late last year the Council adopted the workgroup’s suggestions. They included limiting commercial and recreational fishing in certain places off California, Oregon, and Washington when estimated Chinook salmon numbers north of Cape Falcon, Oregon, fall below a certain level of abundance.

The workgroup recommended that level be set as the average of the seven lowest years of forecast salmon abundance off the northern Oregon and Washington coasts. This average is currently estimated at 966,000. Chinook numbers have remained above that level in recent years; 2007 was the last year when forecasts would have fallen below the threshold.

8 Things You Might Not Know About Threatened & Endangered Species in the Pacific

May 24, 2021 — The following was released by NOAA Fisheries:

It’s Endangered Species Day! This is a time to celebrate the threatened and endangered species in the Pacific Islands region and renew our dedication to protecting and conserving them! With that in mind, we’re bringing you some interesting—and perhaps surprising—facts about our protected species. We’re and sharing how you can help make sure they’re around for future generations to enjoy.

Here’s why we think the threatened and endangered species in the Pacific Islands region are some of the most interesting animals on the planet!

1. False killer whales like to share!

These closely bonded animals not only share their prey with one another, but they’ve also been known to approach human snorkelers and divers with offerings from their fresh catch.

False killer whales are the least abundant species of toothed whale in Hawai‘i. And of the three populations that live here, the main Hawaiian Islands insular population is listed as endangered with fewer than 200 individuals remaining. While encounters are rare, we encourage you to report sightings at the NOAA Marine Wildlife Hotline: (888) 256-9840.

2. Male hawksbill sea turtles spend their lives at sea and are rarely observed or tagged.

The hawksbill population of Hawaiʻi may be the most endangered turtle population in the world. There are fewer than 200 known adult female hawksbill sea turtles (honuʻea) in Hawaiʻi, but scientists don’t know how many males are out there. They suspect the number may be small because only around 20 percent of Hawaiʻi hawksbills that strand (are dead or injured) on the beach are male. What’s more, incubation temperature determines a hatchling’s sex: high temperatures produce females, suggesting fewer males will be born as global temperatures increase. Report all honu‘ea sightings to RespectWildlife@noaa.gov.

Feds start review of endangered Southern Resident orcas

April 27, 2021 — NOAA’s National Marine Fisheries Service says it’s starting a five-year status review of the Southern Resident orcas.

NOAA Fisheries published a notice in the Federal Register about the status review last week, The Skagit Valley Herald reported. The whales were listed as endangered in 2005 under the federal Endangered Species Act.

Since the 1990s, the number of orcas in the three family groups — called J, K and L pods — that make up the population has dropped from the high 90s into the 70s.

The orcas, also called killer whales, live along the West Coast and frequent the Salish Sea.

Since 2005, the orca population has decreased from 88 orcas to a recent low of 72, according to the Center for Whale Research and NOAA Fisheries. As of February, the population was estimated at 75 with some recently identified calves.

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.

WASHINGTON: Seattle Harbor Expansion Would Push Out Endangered Whales, Conservation Group Says

March 5, 2021 — The Trump administration rushed through a project to expand Seattle Harbor for ultra-large container ships that would further threaten endangered Southern Resident killer whales, according to a lawsuit filed Thursday.

Only 75 Southern Resident killer whales swim the Salish Sea — a number that has increased since three baby whales were born in the relatively quiet waters of the pandemic. Noise from whale watching boats and ships headed to and from ports across the Pacific will increase when pandemic restrictions are lifted.

Added to that is a new worry: the underwater cacophony of ultra-large container ships that would visit Seattle Harbor, in the heart of the whales’ home waters, and the release of hundreds of thousands of cubic yards of toxic material dredged during the harbor project.

The three pods, or family lines, of Southern Residents took a major hit in the late 1960s when aquariums stole 45 Southern Residents from their families, and killed another 14 in the process. Only one of the whales taken during that time survives today: a 53-year-old whale who lives at the Miami Seaquarium. The Seaquarium calls her Lolita, while supporters who want her returned to a protected cove of the Salish Sea call her Tokitae.

Study: Chinook salmon are key to Northwest orcas all year

March 4, 2021 — For more than a decade, Brad Hanson and other researchers have tailed the Pacific Northwest’s endangered killer whales in a hard-sided inflatable boat, leaning over the edge with a standard pool skimmer to collect clues to their diet: bits of orca poop floating on the water, or fish scales sparkling just below the surface.

Their work established years ago that the whales depend heavily on depleted runs of Chinook, the largest and fattiest of Pacific salmon species, when they forage in the summer in the inland waters between Washington state and British Columbia.

But a new paper from Hanson and others at the NOAA Fisheries Northwest Fisheries Science Center provides the first real look at what the whales eat the rest of the year, when they cruise the outer Pacific Coast — data that reaffirms the central importance of Chinook to the whales and the importance of recovering Chinook populations to save the beloved mammals.

By analyzing the DNA of orca feces as well as salmon scales and other remains after the whales have devoured the fish, the researchers demonstrated that the while the whales sometimes eat other species, including halibut, lingcod and steelhead, they depend most on Chinook. And they consumed the big salmon from a wide range of sources — from those that spawn in California’s Sacramento River all the way to the Taku River in northern British Columbia.

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.

11 Cool Cetaceans Facts

February 17, 2021 — The following was released by NOAA Fisheries:

Marine mammals in the cetacean family include whales, dolphins, and porpoises. These animals are often referred to as “sentinels” of ocean health, providing insight into marine ecosystem dynamics. Learn more cool things about cetaceans below.

1. They tend to be social and live in groups. Cetaceans may communicate by slapping the water.

Dolphins and porpoises exhibit complex communication and echolocation by making squeaks, buzzes, whistles, and clicks that can be heard from miles away. They are also thought to communicate by slapping the water’s surface with their tails or bodies.

2. Killer whales are part of the dolphin family. There are three main types of killer whales, or ecotypes, in the North Pacific: Resident, Transient, and Offshore.

In fact, they are the largest member of the Delphinidae, or dolphin family. Members of this family include all dolphin species, as well as other larger species such as long-finned pilot whales and false killer whales, whose common names also contain “whale” instead of “dolphin.”

Each North Pacific killer whale ecotype differs in appearance, diet, habitat, genetics, and behavior. While all three types share at least part of their habitats, they are not known to interbreed. Resident killer whales usually eat different varieties of fish, primarily salmon. Southern Resident killer whales prefer Chinook salmon, some of which are endangered. Transient (or Bigg’s) killer whales eat other marine mammals, such as seals, and squid. Offshore killer whales primarily eat sharks and scientists have discovered that the whales’ teeth are worn down over time due to sharks’ rough skin.

In January, 2019, an experienced group of killer whale biologists launched an expedition from the southern tip of Chile into some of the roughest waters in the world, searching for what could be a new species of killer whale.

3. Blue whales have the biggest hearts on the planet.

The heart of a blue whale weighs more than 1,000 pounds, the weight of an average dairy cow.
