Be on the lookout for some special visitors to Puget Sound!

Here at the Aquarium we have plenty of incredible things to see right inside our building—but sometimes, if we’re lucky, we get a special treat just off the pier. This past St. Patrick’s Day, some fortunate Aquarium guests had the chance to view a wild bottlenose dolphin cruising through Elliott Bay.

Bottlenose dolphins are not common to our local waters but our friends at Cascadia Research have reported regular sightings of a small group of five to six bottlenose dolphins since September 2017. Members of the Orca Network and Cascadia Research, along with collaborators from California, have been able to identify two of the dolphins that have been photographed as mature females with the nicknames “Miss” and “Stump.”

Seen from Seattle Aquarium March 17, 2018.

The two identified females are at least 35 years old and have been observed off the coast of California since the early 1980s. Researchers were able to identify the females using unique nicks and marking on their dorsal fins, similar to the way local researchers are able to identify individual orca whales. While bottlenose dolphins have made brief appearances over the past two decades in Puget Sound, they are not a resident species in our area. In fact, “Miss” and “Stump” are almost 1,000 miles from home, which is the San Francisco Bay Area.

Keep your eyes peeled to help researchers!

Local researchers and volunteers have been trying to spot and photograph the bottlenose dolphins in an attempt to see who is traveling with “Miss” and “Stump.” They need high-quality photographs so they can spot unique identifiers and better understand why the bottlenose dolphins might be traveling so far north.

If you see bottlenose or other species of dolphins anywhere in Puget Sound, please call in your reports to Cascadia Research at (360) 943-7325, or email danderson@cascadiaresearch.org.

Seattle Aquarium diving birds get a thumbs up from the doctor

Routine checkups are important for everyone—including the animals at the Aquarium. Recently, our bird & mammal team conducted routine checkups for all 15 of the alcids that call the Seattle Aquarium home.

Alcids are a family of birds indigenous to the Northern Hemisphere and are commonly found in the Pacific Northwest. Here at the Aquarium we have four different types of alcids including tufted puffins, rhinoceros auklets, common murres and pigeon guillemots.

Common murre

A unique characteristic of alcids, as compared to their southern cousin the penguin, is that alcids can not only swim underwater—they can also fly through the air like the majority of birds! Amazingly, the deepest-diving alcid at the Aquarium, the common murre, can swim to depths of 350–400 feet below the water’s surface and stay submerged for one to two minutes at a time.

Fifteen checkups over the last month

Preventative medicine is an essential element in the care our animals receive. Regular checkups include evaluations of the animals’ environments, observations of their behavior and routine physical examinations of the animals themselves.

Tufted puffin

Throughout the last month, all of the alcids in our care were examined by Aquarium life sciences staff and our vet, Dr. Caitlin Hadfield. The goal of the checkup is always to catch any possible areas of concern before they might progress into issues, and the good news is: all the birds are doing great!

The Aquarium’s diverse family of diving birds

The diving birds at the Aquarium have a wide spectrum of ages that caregivers must consider as they conduct their checkups. Some birds are elderly, including our pigeon guillemot (at least 32 years old) and the elder rhino auklet, Stanley (age 19). Some are younger—all the way down to our young-of-the-year tufted puffin (7 months).

Rhinoceros auklet

What can you do to help alcids?

While it’s  not possible to ensure checkups for every animal living in the wild, there are a few things you can do to help safeguard the health of diving birds—and all marine creatures.  Like every one of us, they rely on a healthy ocean for their survival. When we care for our marine environment, we’re also helping to ensure that alcids can thrive.

Governor signs executive order to help protect southern resident orcas

Seattle Aquarium President & CEO Robert W. Davidson and Aquarium staff joined Governor Inslee, regional and tribal leaders, and environmental advocates at the Daybreak Star Cultural Center in support for our native southern resident orca population this past Wednesday.

The event marked the signing of a new plan by the governor that outlines a series of actions to help protect both our southern resident killer whales and chinook salmon—the primary food source of orcas native to the Salish Sea.

In his speech, the governor emphasized the cultural and economic importance of both species and the challenges they face. In Puget Sound, the population of southern resident orcas has declined from 98 in 1995 to just 76 today. Further the orcas’ primary food source, the chinook salmon, have also seen declines in their populations and are listed on federal and state endangered species lists.

The executive order forms a task force of stakeholders to make new recommendations on how we can better protect our orcas and salmon. The order also instructs seven state agencies to immediately boost orca recovery and outline long-term steps to better address factors leading to population decline. The order instructs the taskforce and agencies to work with leaders in British Columbia, Oregon, California, Idaho and Alaska to ensure strategies are coordinated and working together.

As Gov. Inslee noted at the event, “Washington is lucky enough to have two iconic animals: orcas and salmon, whose destinies are both intertwined and in peril.”

Seattle is the world’s only major metropolitan area with a resident population of orcas and the fate of our three orca families, J, K and L pod, is linked to all of us. Human influences on the ocean ecosystem affect whales everywhere. Our southern resident orcas were listed as endangered in 2005. The Center for Biological Diversity has analyzed our local resident orca population and, if trends continue, our local pods could go extinct within 100 years—possibly as soon as 30 years from now.

The time to act is now, and we are excited to see Gov. Inslee, tribal leaders, local officials and many others taking steps to ensure we protect these incredible animals. If you would like to read Gov. Inslee’s executive order, you can view it here. Want to learn more about orcas? Check out some of the educational resources on our website, or visit the orca Family Activity Center the next time you’re at the Aquarium.

Creature feature: amazing, long-lived rockfish

There are more than 100 different species of rockfish around the world; 68 of those are found along the Pacific coast of North America; 24 of them live in the waters of Puget Sound; and about 14 different species can be seen at the Seattle Aquarium!

All in the Scorpaenidae family

All rockfish species share some physical characteristics—such as jutting lower jaws and large dorsal fins with well-developed spines— but there are significant differences between the species as well. They can be anywhere from six inches to three feet long. They may be red, orange, black or green—and splotched or striped. They’re found at depths ranging from 40 to 2,000 feet. And they may group together in large schools or live solitary lives in their rocky homes.

Old timers

Compared to most other fish species, which live from two to 10 years, some rockfish species live very long lives—100 years or more! But there’s a downside: many longer-living rockfish don’t begin breeding until they’re nearly 20 years old. Because they’re susceptible to overfishing, that means that some rockfish don’t have a chance to reproduce before they’re caught and put on a dinner plate. That’s why most rockfish are listed as a species to avoid in sustainable seafood consumer guides.

Rockfish at the Seattle Aquarium

The rockfish pictured in our matching game below were collected by Aquarium staff last summer at Neah Bay on Washington’s outer coast. Regardless of where we collect rockfish, though, we focus on younger fish. Why? Choosing young fish gives you a chance to watch them grow through each of their different life stages. More importantly, some rockfish populations are threatened— and by leaving older, larger rockfish in the wild to reproduce, we limit our impact on their populations.

Research to understand rockfish population sustainability

Rockfish are listed as species of concern in Washington state, and some are listed as threatened (yelloweye) and endangered (bocaccio) under the federal Endangered Species Act (ESA). Understanding long-term population stability and young-of-year (YOY) recruitment events is important to the effective management of these species. With support from members and donors like you, the Seattle Aquarium has been documenting rockfish at five different research stations in the Strait of Juan de Fuca, just southeast of Neah Bay, since 2004. Since 2009, we’ve expanded the number of survey sites to include nine in Puget Sound, for a total of 14 sites that we survey semiannually to quarterly to gain insight into both seasonal and annual differences in rockfish numbers, and to document significant YOY recruitment events.

Seattle Aquarium 2018 Hawaii reef research report: part 2 of 2

2018 marks the tenth consecutive year that Seattle Aquarium staff members have conducted Hawaiian reef fish and coral health research along the northwestern side of the Big Island of Hawaii. Follow along as Seattle Aquarium Curator of Conservation Research Shawn Larson recaps the experience. To read part 1, click here (link to first blog post).

Day 4: Thursday, January 25—a very fishy day!

Today we headed south to Kona to meet up with Mark Johnson, who took us out on his boat to survey site 8 south of Kona and just north of Captain Cook, where the acropora corals are. We can only survey this site by boat, and it was a perfect day to be on the water.

Site 8 was very fishy, but the corals here also bleached in 2016 and still haven’t recovered. We hope they look better the next time we’re there.

We motored back up north and surveyed sites 3 and 4, off Old Kona airport. They were very fishy—at least over 1,000 fish at each site. Awesome!

After our dives we stopped by the Division of Aquatic Resources (DAR) office to say hi to our partners there, Dr. Bill Walsh and his crew.

Day 5: Friday, January 26—a change of pace

Today we headed over to Hilo to give our talk at the University of Hawaii Hilo. It was attended by 30 students and locals, and went very well. We again shared information about the Aquarium, our plans for the future, and the results of our research. The students were very interested—our talk was 40 minutes long and they asked questions for nearly 30 minutes afterward! Back to Puako if the afternoon to have dinner with our past-years hosts, Dom and Marie Addario.

Day 6: Saturday, January 27—shark sighting!

Today we got to do some exploratory dives to see if there are areas that we could survey if we had more time. We explored areas north of site 1 and deeper that we hadn’t been to before. We found lots of schools of fish, garden eels and wire corals.

Then we drove south back to Kona to dive Crescent Beach, an area just south of the harbor. Here there were many fish and lots of healthy-looking corals. We even saw a tiger shark! Then we headed into town for dinner with our boat captain Mark and his wife April.

Day 7: Sunday, January 28—wrapping up

We couldn’t dive today as we are flying tomorrow, so all gear got an extra rinse and a complete dry for packing tomorrow. We returned all of our tanks and weights to Kohala Divers in Kuawahai and went back to Mike Budd’s house to relax. Later in the evening, we had dinner with Narrand and his wife Urmila, former owners of the Puako general store and super nice folks.

Day 8: Monday, January 29—all good things must come to an end

Time to say goodbye to Mike and Puako. It was a very successful trip—we were able to get all our surveys done, gave two talks, and made more partnerships and connections. Back to Seattle to start counting fish!
