Hope of seeing larger orca population dashed by calf’s death

A seven-week-old baby orca born to our Southern Resident pods was reported missing and presumed dead today. This was the newborn orca who brought so much hope and excitement to our area, being the first reported birth in more than two years.

When I called Ken Balcomb this morning, he was in a “subjective” state of mind, as he put it. Ken, of the Center for Whale Research, has been keeping track of the three Southern Resident pods since 1976, and he’s clearly worried that these whales may be headed for extinction.

As we talked on the phone, Ken was peering through the large windows of his home on San Juan Island and watching a large purse seine vessel scooping up chum salmon and possibly other species as bycatch.

“I look at this every day, and I’ve seen this for almost 40 years,” Ken said. “There is no letup on the human part. Virtually no fish are getting past the outlet. We know the Fraser River runs are in poor shape, and our management doesn’t seem to take any kind of ecosystem approach.”

Salmon biologists set the sport and commercial fishing seasons based on an estimate of the number of fish returning. They update that estimate during the season based on harvest numbers caught in the nets.

“Whatever they are doing, it obviously has not worked, since we’ve seen run after run not doing well,” Ken said. “I get subjective about it and wonder when our society is going to do something to get more prey (for the whales).”

Ken said there was much hope for the seven-week-old orca, designated L-120, the third known offspring of the 23-year-old mother designated L-86.

“I was optimistic,” he told me. “When we first saw the baby, it had a squished-looking head, but even human babies can be born with a flattened head.

“Within a week, it was filling out well and was energetic,” he continued, and there was no reason to believe the calf would die.

The Southern Residents are known to bear a heavy burden of toxic chemicals, but transient killer whales are even more contaminated. The difference may be that transients, which eat marine mammals, may be getting enough food. Was the orca mom unable to nurse her baby? Did the toxic chemicals cause an immune deficiency? Or was there another problem? We’ll probably never know.

All three orca pods were probably out in the ocean when the youngster disappeared. The mom was seen with other whales on Friday, Saturday and Sunday without the calf — something that would not happen if the baby were alive.

L-120 was the third calf born to L-86. Her second calf, L-112, washed up dead at Long Beach in February 2010. After much investigation, researchers concluded that L-112 had died of blunt force trauma, but what caused the injury was never determined. Ken suspects some kind of explosive detonation, although that cause was discounted by investigators.

Howard Garrett of Orca Network said the orcas have faced a shortage of food, toxic chemicals, routine shooting with guns and a series of captures that depleted the population.

“We haven’t treated these magnificent orcas well at all,” Howie said in a news release. “As a society we are not successfully restoring this orca community, despite the many warnings and legal declarations.

“Our challenge is clear: Bountiful salmon runs must be restored and protected or we won’t see resident orcas in the Salish Sea in coming years,” he added.

The latest population count places the total number at 78, the lowest number since 1986, according to records by the Center of Whale Research.

Unmanned aircraft provides unique views of killer whales

Unmanned aerial vehicles, commonly called drones, could play an increasing role in killer whale studies, according to Brad Hanson, a researcher with NOAA’s Northwest Fisheries Science Center who has been studying Puget Sound’s orcas for years.

Brad said a plan to use UAVs (he doesn’t like “drones”) has been on the drawing board for several years. Unmanned aircraft can fly over the whales far more cheaply than a full-size helicopter, which has been used in the past. The small aircraft also may be able to come in close for biological samples with less disturbance to the whales than when operating from a research boat.

“I’ve been looking at this for a long time,” Brad told me. “We have it in our (Endangered Species Act) permit to be able to use a UAS (unmanned aircraft system).

Remote-controlled aircraft have been used by researchers to study seals and penguins in the Arctic and to estimate their populations with less disturbance than approaching the animals on the ground. They’ve also been used to count birds in remote areas.

In August, NOAA and Vancouver Aquarium researchers teamed up to test the use of a remote-controlled hexacopter as they observed Northern Resident killer whales in British Columbia. Mounted with a high-resolution camera, the copter captured some amazing videos and still pictures, including those on this page. See also NOAA’s website.

One can learn a lot from a good aerial view of a killer whale, including general body condition, Brad told me. From a boat on the water, it is often difficult to tell if an orca is healthy, underweight or pregnant. From above, a whale’s girth is easier to assess.

Researchers involved the British Columbia study — including John Durban of NOAA’s Southwest Fisheries Science Center and Lance Barrett-Lennard of Vancouver Aquarium — identified several females who seemed to be pregnant.

They also spotted two whales that seemed emaciated. Those animals later went missing and are presumed dead, confirming that they were in poor health. What is not evident from photos, however, is the cause of the problem, Brad Hanson said. Were the whales suffering from disease, injury or another problem that caused them to lose weight, or was it simply a lack of food?

Aerial photos also can be used to measure the length of a whale and, over time, determine the growth rate at various periods in its life.

Brad said the ultimate goal is to develop health assessments for the Southern Residents, listed as “endangered” under the federal Endangered Species Act. A lot of technical details need to be worked out, he said, but the plan is to use unmanned aircraft to collect breath and fecal samples from the whales.

A breath sample is the next best thing to a blood sample, Brad told me, and fecal samples provide information about stress hormones, potential pathogens and other things.

“If you tied that in with imaging, we might be able to build individual health profiles and begin to understand when something is going wrong,” Hanson said.

Currently, breath samples are taken by driving a boat alongside the whales and holding out a pole with an apparatus on the end. Fecal samples are taken by following the whales and sifting feces from the water.

If a small helicopter flown from a boat some distance away can be used, the result would be less intrusive than a boat coming near the whales.

In the study in British Columbia, the general goal was to keep the UAV at least 100 feet above the whales. The study also included some closer movements to test the reaction of the whales. No obvious changes in behavior were noticed, Brad said.

One permit still is needed for Hanson to operate a UAV in Washington state. The Federal Aviation Administration must issue a certificate of authorization, or COA, which spells out limitations of the flight to avoid other aircraft operating in the area.

The Canadian experiment received similar permits from Fisheries and Oceans Canada and Transport Canada. The aircraft was an APH-22 marine hexacopter built for NOAA by Aerial Imaging Solutions.

Ironically, amateurs in the United States are allowed to operate unmanned aircraft in some areas without permits. But flying around wildlife could create unanticipated problems for the animals. And anyone operating around endangered whales could be in violation of other state and federal laws — such as the Endangered Species Act or Marine Mammal Protection Act — if they fly below 1,000 feet.

Steelhead could be running into a trap at the Hood Canal Bridge

Fishermen fish for salmon north of the Hood Canal bridge, but researchers say the bridge may be an obstacle to the migration of young steelhead. Kitsap Sun photo by Larry Steagall

I’ve often wondered if the Hood Canal bridge might be an obstruction for killer whales, which could simply choose to back away from the wall of floating pontoons, which are anchored to the seabed by a confusing array of crisscrossing cables. Old-timers have told me that orcas used to come into Hood Canal more frequently before the bridge was built.

What I never considered seriously, however, was that the bridge could be an obstacle for fish as well. In Sunday’s Kitsap Sun, I wrote about recent findings from a study tracking juvenile steelhead by means of implanted acoustic transmitters. The study was conducted by researchers at NOAA’s Northwest Fisheries Science Center.

GraphicTemp

The bottom line is that something is happening at the bridge, where many of the transmitters either disappeared or winded up staying in one place near the bridge, continuing to send out their signals for weeks. The leading hypothesis is that seals or other predators are eating the young steelhead, and some of the acoustic tags are being digested and excreted near the bridge.

Why the bridge serves as an obstacle to steelhead remains unclear. But other studies have suggested that steelhead swim near the surface. As they move out of the canal, the fish may encounter the bridge pontoons as a physical barrier, since the concrete structures go down 12 feet underwater. Also, currents around the pontoons could be a strange condition for the fish. If a young steelhead slows down in the process, a harbor seal or other predator could be waiting to take advantage of the situation.

We’ve all heard about sea lions capturing adult salmon by hanging out at fish ladders at Seattle’s Ballard Locks in Seattle or at Bonneville Dam on the Columbia River. Maybe the same thing is happening at the Hood Canal bridge with smaller prey as the target of the marine mammals.

I was also intrigued by an analysis conducted by Tarang Khangaonkar, a researcher at Pacific Northwest National Laboratory in Seattle. He told me that in all the models of circulation in Puget Sound and Hood Canal, the bridge tended to be ignored. Since the pontoons go down 12 feet, the bridge disrupts the relatively thin low-salinity surface layer moving out of Hood Canal.

Tarang calculates that the bridge could reduce the circulation by 10 percent or more, which has serious implications, not just for steelhead at the bridge but for the ecological health of all of Hood Canal.

“We have to examine what the bridge is doing,” Tarang told me. “It slows the entire system down. Water quality is maintained in Puget Sound by the flushing effect, which flushes the system out and maintains a balance. Our preliminary finding is that it could slow down by about 10 percent. That effect is cumulative.”

The bridge, he said, could effectively create a more stagnant body of water, where oxygen can become depleted. More study is needed, he said.

Most of the folks I interviewed for this story agreed that the first priority for further research was to see what is happening to the steelhead — and possibly chinook and chum salmon — at the bridge. Studies could focus on the fish, predators and currents at the bridge.

The project is gaining support, but it could require a special legislative appropriation of about $2 million.

Killer whales expected to head south any day now

UPDATE, Oct. 4
Orca Network reported a brief appearance of J pod this week near San Juan Island: “On Wednesday, October 1, J pod plus L87 Onyx and a few K pod members shuffled in small groups spread out up and down the west side of San Juan Island for over eight hours, then returned around midnight and continued vocalizing near the Lime Kiln hydrophones for another few hours.”
—–

As chum salmon swim back to their home streams in Puget Sound this fall, three killer whale pods — the Southern Residents — can be expected to follow, making their way south along the eastern shoreline of the Kitsap Peninsula.

These forays into Central and South Puget Sound could begin any day now and continue until the chum runs decline in November or December. The Southern Residents, which typically hang out in the San Juan Islands in summer, have not been spotted for several days, so they are likely somewhere in the ocean at the moment, according to Howard Garrett of Orca Network.

This year, Orca Network has created a map of good viewing sites to help people look for whales from shore. As the orcas move south into Puget Sound, Orca Network’s Facebook page becomes abuzz with killer whale sightings. Observers can use the information to search for the whales from shore.

From my experience, it takes a bit of luck to find the orcas, because they are constantly moving. But the search can be fun if you consider it an adventure and don’t get too disappointed if you don’t find the whales right away.

Howie said expanding the network to include more land-based observers can help researchers track whale movements and occasionally go out to pick up samples of their fecal material or food left over from their foraging, helpful in expanding our knowledge about what they are eating.

Whale reports may be called in to Orca Network’s toll-free number: (866)-ORCANET, emailed to info@orcanetwork.org, or posted on Facebook, www.facebook.com/OrcaNetwork.

The new Viewpoints Map shows locations where killer whales have been sighted in the past, or else they lie along a known route of their travels.

I told Howie about a few good viewing locations in Kitsap County, based on my experiences, and he said he would welcome ideas from others as well.

“It’s a work in progress,” Howie said. “They just need to be locations that are public and accessible.” If you know of a good whale-watching spot, you can contact Howie or his wife Susan Berta by email, info@orcanetwork.org.

If offering a location for the map, please give a clear description of the site and state whether you have seen whales from that location or just believe it would work based on the view of the water.

Some people have expressed concern that real-time reports of whale movements may encourage boaters to go out and follow the orcas in Puget Sound, disturbing their feeding behavior at a critical time of year. But Howie says Orca Network has increased its reporting through the years and has not heard of many problems.

“It seems like a potential problem that never really happens,” he said.

Winter weather and rougher seas makes it difficult to find the whales from the water, Howie noted. As in summer, boaters are required by federal regulation to avoid interfering with their travels. See the “Be Whale Wise” website.

When reporting whale sightings to Orca Network, observers are asked to list the species, location, time, direction of travel and approximate number of animals. When reporting killer whales, the number of adult males with towering dorsal fins should be noted. Also report any behaviors, such as breaching, spy-hopping or feeding. Good photographs are especially valuable.

Sighting reports can be found on the Orca Network website, Facebook page or Twitter feed. One can also sign up for email alerts from the website, which includes reports of recent sightings as well as archives going back to 2001. The site also tracks news and research developments.

As Howard stated in a news release:

“We are very fortunate to live in a place where we can look out from nearby shorelines and see those majestic black fins parting the waters. We are thankful for the hundreds of citizens who report sightings each year, providing valuable data to help in recovery efforts for the endangered Southern Resident orcas.”

Amusing Monday: New worlds explored with GoPro

The GoPro action camera is the force behind hundreds of amazing videos. Thanks to this unique camera, we have raced across the land, soared into the sky and dove beneath the waves.

We have not only followed people closely as they’ve undertaken wild adventures, we have traveled with a variety of animals through their natural habitats. One of my favorite videos, shown first on this page, includes some of the best animal shots taken by many photographers and compiled by the producers of Tastes Like Pizza.

The GoPro is no longer the only compact, rugged and mountable high-definition camera around, but the name has become synonymous with the type of videos I’d like to highlight today. The history of the GoPro was the subject of an interesting “60 Minutes” segment, in which Anderson Cooper mentions that the GoPro has been used again and again to capture video for the television program.

If it’s action shots you like, check out the second video, a compilation by GoPro, created as a promotion for its Hero3 camera. If you’re like me, you will be intrigued by the time-lapse photos in this video and transfixed by the action shots.

How about some more great animal shots? Of course, all these videos should be viewed full-screen:

Jellyfish Lake: Photographer Nana Trongratanawong of Bangkok, Thailand, shot this amazing video in a lake in Palau. She used different music in the video she posted on her website.

Humpback whales: Drone photographer Justin Edwards captures some amazing shots of a young humpback whale and its mom swimming off the coast of Maui in February of this year. About halfway through, you can see the baby riding on its mom’s back.

Shark Riders: Free divers Roberta Mancino and Mark Healey create a dreamlike video that tells a story of becoming one with the ocean and its creatures.

Teaching a pelican to fly: After a storm, a young pelican was found stranded on a beach in Tanzania>The staff of the nearby Greystroke Mahale resort adopted the animal, named him “Big Bird” and reminded him how to fly. With a GoPro attached to his beak, the pelican investigated the waters, then swooped back around to the beach where the flight instructors were waiting.

Amusing Monday: Dolphin becomes friend with dog

I have been intrigued by some unusual animal friendships, which I’ve reported here in Water Ways: a baby hippo and a 130-year-old tortoise, a cat and a crow, an orangutan and a hound, an elephant and a dog. See Amusing Monday, Nov. 12, 2012.

But somehow I missed the tantalizing story of a dolphin named Duggie and a dog named Ben on Tory Island, Ireland. The television show “National Geographic Wild” is now telling the story of this unusual friendship, which began in 2006.

That seems like a long time ago, and I’m trying to find out whether the friendship might still endure or whether the National Geographic people used old footage in their telling of the story.

I like the National Geographic clip (first video on this page), because it includes a discussion by Cesar Millan, known as “the Dog Whisperer.” But I have a greater appreciation for the inquisitive approach taken in an earlier production for BBC’s “Countryfile,” a program mostly about places in and around Ireland (second video).

Additional information was filled in by reporter Anita Guldera in The Independent. She tells us that Tory Islanders believe the female dolphin’s friendship with Ben came about after she lost her mate. It all started about the time a male dolphin washed up dead on the island.

I stumbled across the dolphin-and-dog story after someone emailed me a lovely video about a dolphin saving a dog from a shark attack. The video, called “Dolphin and Dog,” was put together by a Dutch woman named Ine Braat. I say the video was “lovely” because the music creates a mood around this dolphin-and-dog friendship. But it’s fiction, mostly based on clips from the movie “Zeus and Roxanne.”

You may wish to check out some of Ine’s other lovely compilations posted on her website.

Another story about a dog and a dolphin is a more gripping tale, because it involves a human whose life was in real danger. Lynn Gitsham of Carrickalinga, Australia, says she was rescued by a pod of dolphins after falling into the ocean while trying to get to her dog. Reporter Michelle Vella tells the story for Australia’s Seven West Television (below).

Amusing Monday: Orca surprises fishermen

I’m on vacation this week, but I wanted to revisit a video I first presented in June of last year. We see fishermen playing a fish while a killer whale plays the fishermen. I interviewed the excited man in this video soon after the fishing trip to explain some of his comments. The video has now been viewed more than 1.2 million times.

Frank Sanders is an experienced hunting and fishing guide, yet he screamed with excitement when he reeled in his fishing line to find a killer whale at the other end.

The video, posted two weeks ago by Frank’s deckhand Charlie Barberini, has been viewed more than 800,000 times on YouTube. That doesn’t count the number of times people watched the original Facebook post and videos copied from the original.

The video has raised numerous questions, such as why Frank is showing his ring to the camera and looking for someone named Jason. I was able to reach Frank in Hawaii, where he was on a fishing trip, and he filled in some of the blanks.

Frank, Charlie and others were fishing for halibut near Ninilchik in Cook Inlet in Southern Alaska. They had seen a couple killer whales go by a few times but not close to the boat. I think Frank told me the orcas were eating sockeye salmon that were in the area. Suddenly, out of the depths, a killer whale appeared following the fish on his line.

You need only to see and hear the video to know how much excitement that generated.

Frank told me the orca did not appear to want the fish. It was playing with the fishermen in the boat, grabbing the fish, pulling the line out about 200 yards, then bringing it back. The whale circled the boat a few times, he said, tangling fishing lines played out from other poles. This went on for at least 10 minutes before the whale went on his way.

The whale, of course, had the strength to bite the fish through and take it away or snap the line any time he chose, Frank said. But it didn’t.

About his ring, Frank explained that he travels a lot for his business, Alaska Trophy Hunters. In fact, he is away from his wife about as much as he is with her, so he sends her hunting and fishing pictures from all over Alaska and displays his ring for her.

As for Jason, I didn’t get the full story, but I heard enough to understand that this, too, was an inside message. Jason is Frank’s best friend and the best man at his wedding. Jason was in a four-wheeler accident and suffered a severe brain injury. He was in a coma for a month but then was getting better. Jason set up a personal website on “Caring Bridge” to share information back and forth with his friends and family. Frank wanted Jason to understand that he was thinking about him during this adventure and was showing him a special bracelet they shared. Unfortunately, Jason suffered a stroke and may not pull through. (Update, June 24, 11 a.m.: I just received word from Frank this morning that Jason passed away yesterday.)

After the video was posted, Frank reportedly told reporter Lydia Warren of London’s Daily Mail:

“Fishing gets kind of repetitive after 18 years, but this is one of the most exciting things that has happened to me.”

What we know and don’t know about killer whales

This week’s report about Puget Sound’s endangered killer whales contained little new information, but the intent was not to surprise people with important new findings. The report (PDF 14.3 mb), published by the Northwest Fisheries Science Center, was a nice summary of 10 years of research and ongoing efforts to unlock the secrets of the mysterious Southern Residents.

NOAA also released the video, at right, which sums up the report with great visuals. Make sure you go full-screen.

On Wednesday, I participated in a telephone conference call to link reporters with killer whale experts in our region. On the line were Lynne Barre, Mike Ford and Brad Hanson, all with NOAA Fisheries out of Seattle. I’ve been wrapped up with other reporting assignments, so the Kitsap Sun’s editors chose to run a solid story by Associated Press reporter Phuong Le. See Kitsap Sun, June 25.

Let me make a few quick observations:

Lynne Barre said one of the greatest mysteries, to her, is why killer whales suddenly go missing. It’s a vexing problem, and I always get a little nervous when the whales return in the spring. One year, six of the Southern Residents failed to show up. It was a real blow to the close-knit orca community and to the struggling population, and I’ve never forgotten the dismay of everyone who cared about these animals.

Healthy killer whales seem to go missing as often as elderly or sick ones. Only a few bodies ever wash up on the beach. Even when one is found, the cause of death often remains uncertain, as in the case of L-112, found to have died of “blunt-force trauma” from some unknown object.

Much more needs to be learned about disease in the animals, Lynne said. Future research could involve more tissue biopsies and breath samples in an effort to identify early signs of disease.

For Brad Hanson, another mystery is the whales’ seemingly unpredictable behavior and their “fundamental relationship with prey.” We all assume that their primary goal in life is to find fish to eat, but how good are they at this essential task? Pretty good, I would guess. Often before we learn that chinook are abundant off the Washington Coast, we find out that the killer whales are already there.

Maybe the reason the whales have been spending so much time away from Puget Sound the last couple years lies in the lower returns of Fraser River chinook, which pass through the San Juan Islands in the summer. Scale and fecal samples have shown that Fraser River chinook are the most consistent prey of the resident orcas.

In previous conversations, Brad has told me that he would love to communicate with the whales, to find out who is in charge and why a group of animals may suddenly turn around and go in the opposite direction. Howard Garrett of Orca Network recalls a time when all three Southern Resident pods were in the Strait of Juan de Fuca heading into Puget Sound. Suddenly K and L pod turned back, while J pod continued on. Howie says it was as if they knew there were not enough fish for the entire population, so J pod went on alone, saying, “See ya later.”

Mike Ford wants to know why the population has not increased more than it has. Could it be some limitation in the ecosystem, such as the fact that other marine mammals — such as seals and sea lions — have been increasing and taking a sizable bite out of the available salmon population? We know that Northern Residents, who also eat fish, don’t overlap territories much with the Southern Residents. Living up north, the Northern Residents have better access to some salmon stocks — including those that originate in Puget Sound. If the Northern Residents get to them first, the fish are not available for the Southern Residents — or so goes one hypotheses. The Northern Resident population has tripled in size, while the Southern Residents have stayed about the same.

Oddly enough, this potential competition for chinook salmon reminds me of exactly what is taking place with regard to commercial fishing enterprises. Washington fishermen complain that the Canadians are taking salmon that should get back to Washington. Canadian fishermen complain that Alaskans are taking salmon bound for Canada. Only Alaskan fishermen — and those who go to Alaska to fish — can catch a portion of the salmon going into Alaskan rivers as well as some destined to travel south.

One of the new things that did come up in Wednesday’s conference call was a renewed effort for U.S. killer whale biologists and managers to work with their counterparts in Canada. “We will be partnering with them on issues of salmon fisheries and how that may affect the whales,” Lynn said, adding that other cross-border efforts could involve vessel regulations and targeted research efforts.

During Wednesday’s conference call, nobody talked about the potential effects of military activities and the possible injury from Navy sonar until a reporter brought up the issue. The question was referred to NOAA Fisheries headquarters in Silver Spring, Md., where officials review the Navy’s operations and issue incidental take permits. That was the end of that discussion.

I know the Navy is conducting research in an effort to reduce harm to killer whales and other marine mammals. I get the sense, however, that more could be done immediately if connections were made between knowledgeable killer whale researchers in our region and those making decisions on the opposite side of the country.

Amusing Monday: A visit with wildlife via webcam

It seems kind of strange that we can spy on wildlife in a very personal way, thanks to modern technology.

The animals never notice the hundreds of humans peering over their shoulders via webcam. If they could know what is going on, I actually think they’d prefer the camera to the disturbance that even one person would create by crowding in that close.

It’s the time of year when many birds are active on their nests, so I thought I’d bring you some of the best videos on the web, weeding out those that are inactive or don’t have much going on right now.

The University of Montana operates two live osprey cams at part of its Montana Osprey Project. I believe the nest at Riverside Health Care Center in Missoula (shown in first video player) contains two chicks, while the nest at Dunrovin Ranch in Lolo contains three chicks.The high-quality video and sound make you feel you are right there with the birds.

Alberta Conservation Association and its sponsors have set up cameras to observe three prime nesting boxes for peregrine falcons in Edmonton, Alberta. Chicks have hatched in each nest, and we can watch (in real time) the mothers taking care of their little bundles of fluff. Each bird has a story listed with the video.

Chesapeake Conservancy is in charge of an osprey cam on Maryland’s eastern shore. The live video features Tom and Audrey, who have returned to the nest after spending the winter in South America. I have seen two chicks in that nest.

For a bird of a different character, check out the Puffin Cam at Seal Island National Wildlife Refuge in Maine, where Audubon’s Project Puffin operates a field station. The puffins on the island were wiped out by hunting in 1887, but they were reintroduced by bringing puffins from Newfoundland. More than 50 pairs nest there. (Three live videos are set up to show the puffins.)

If you are interested in watching brown bears feeding on salmon, stay tuned for live videos from Alaska’s Brooks River in Katmai National Park. The action should begin in July, according to information on the website. Meanwhile, you can watch recorded videos from previous times.

One of my favorite live cams is still Pete’s Pond (video player at right), a watering hole on Mashatu Game Reserve in Botswana, Africa. It began as a National Geographic project and is now operated by WildEarth, which features several other wildlife cams. Operators, working remotely, turn the camera to find the best action at any moment.

The Vancouver Aquarium has live cams showing:

If you’d like to see blacktip reef sharks and other fish, check out the video below from the National Aquarium in Baltimore, Md.

For humpback whale, so many fish, so little luck

This amazing photo of a humpback whale chasing a massive school of herring was taken in Prince William Sound by Rich Brenner of the Alaska Department of Fish and Game.

Rich took the picture in April during an aerial survey of herring. He says he has observed many humpbacks feeding on herring during the spring survey, but this whale was not having much luck, probably because the water was so clear. As the whale approached, the herring kept moving away, creating odd patterns in the water.

“As I was watching the scene, I couldn’t help but think that the whale was expending a lot of energy and not receiving much in return,” Rich wrote me in an email. “But the shallow depth and clear water probably did not favor it.”

In the weeks prior to the flight, a large algae bloom covered this area near the village of Tatitlek. If the bloom had continued, the whale and much of the herring might have been difficult to see, he said.

“Thus, we were very pleased to get such a clear view of the situation and observe the movement of the herring along with the whale. The herring school undulated away from the whale, and they were able to keep a gap between them. Only once did we observe the whale lunging forward and getting under the school.”

The second photo, below, shows the whale lunging upward and possibly getting a mouthful of herring. The platform in the top photo is part of a frame for a net pen used to hold hatchery salmon before their release.

The spring herring survey measures the extent of the spawn along the shoreline, which is used to estimate the overall biomass in Prince William Sound.

Rich said he estimated that herring in this massive school would amount to several hundred tons. GIS experts will map the school to help construct a formal estimate of the biomass.

The state has not approved a commercial herring fishery in Prince William Sound since 1999. During the 1980s and early 90s, large numbers of herring were caught commercially, Rich said. Sometime around 1993, the population crashed and has never fully recovered.

“The reason for the depleted biomass, relative to the years when we had a commercial fishery, is a subject that has been hotly debated by scientists and others for the past 20 years,” he said.

As stated in an announcement by ADFG:

“Preliminary spawn estimates (from 2013) are 20.7 mile-days (south of Knowles Head) and 5.5 mile-days (north of Knowles Head), and 3.2 mile-days (Montague Island) for a total of 29.3 mile-days of spawn. This is fewer mile-days of spawn in PWS than in any year in which commercial fishing occurred since 1973.”

Another good source of information on herring is the Prince William Sound Science Center.

The humpback whale may have caught up with some of the fish, as it surges to the surface.
