Extensive floodplain restoration brings new hope to Clear Creek

A giant piece of a cedar log stands erect in a barren landscape north of Silverdale, where a new channel for Clear Creek stands ready to receive water.

Well, maybe this channel won’t be entirely new. Designers working to restore this portion of Clear Creek studied old maps. They tried to align the new man-made channel to the meandering stream that existed 150 years ago, before farmers diverted the creek around their fields.

During excavation, workers uncovered buried gravel — remnants of the old streambed — along with chunks of cedar that had lain along the edge of the stream. Buried and cut off from oxygen, these pieces of wood survived for decades underground, while cattle grazed in the fields above.

Workers excavating for the new channel used their heavy equipment to pull out what remained of a great cedar log. They stood the log vertical and buried one end in the ground — a monument to the past and future of Clear Creek.

Chris May, manager of Kitsap County’s stormwater program, showed me the new channel this week. He said it was rewarding to uncover some buried history and realize that the stream would be restored in roughly the same place.

“We found the old channel,” Chris told me, pointing to a deposit of gravel. “We are pretty confident that we got it right.”

This $3-million project has been conceived and designed as much more than a stream-restoration project. The elevations of the land around the stream have been carefully planned so that high flows will spill into side channels and backwater pools. That should reduce flooding in Silverdale and help stabilize the high and low flows seen in Clear Creek.

The engineers did not calculate the reduced frequency of flooding, but floodwater storage is calculated to be 18.4 acre-feet, the equivalent of a foot of water spread over 18.4 acres or 29,700 cubic yards or 6 million gallons.

In all, about 30,000 cubic yards of material have been removed across 21 acres, including the former Schold Farm on the west side of Silverdale Way and the Markwick property on the east side. Native wetland vegetation will be planted along the stream and in low areas throughout the property. Upland areas will be planted with natural forest vegetation.

The topsoil, which contained invasive plants such as reed canarygrass, was hauled away and buried beneath other excavated soils to form a big mound between the new floodplain and Highway 3. That area will be planted with a mixture of native trees.

Plans call for removal of 1,500 feet of an existing road with upgrades to two aging culverts. Adding meanders to the straightened channel will create 500 feet of new streambed that should be suitable for salmon spawning.

Plans call for adding 334 pieces large woody debris, such as logs and root wads to the stream. Some of that wood will be formed into structures and engineered logjams to help form pools and gravel bars.

“This will be one of the first streams to meet the Fox and Bolton numbers,” Chris told me, referring to studies by Martin Fox and Susan Bolton of the University of Washington. The two researchers studied natural streams and calculated the amount of woody debris of various kinds needed to simulate natural conditions, all based on the size of a stream. (Review North American Journal of Fisheries Management.)

The elevations on the property were also designed so that high areas on opposite sides of the stream would be in close proximity in several locations.

“Beaver will pick that spot,” Chris said, pointing to one location where the stream channel was squeezed by elevated banks on each side. “We want to encourage beaver to come in here.”

Beaver ponds will increase the floodwater storage capacity of the new floodplain and provide important habitat for coho salmon, which spend a year in freshwater and need places to withstand both high and low flows. Because the county owns the flooded property, there won’t be any complaints about damage from beavers, Chris noted.

Clear Creek Trail (PDF 390 kb), which begins on the shore of Dyes Inlet, will be routed along the higher elevations as the trail winds through the property. Three new bridges will provide vantage points to watch salmon after vegetation obscures other viewing areas from the trail. Viewing platforms, as seen along other parts of Clear Creek Trail, were not included in this project but could be subject to further discussions.

Count me among the many people — experts, volunteers and users of Clear Creek Trail — who are eager to see how nature responds when water (now diverted) returns to the new stream channel. For decades, the lack of good habitat has constrained the salmon population in Clear Creek. The stream still has problems related to its highly developed watershed. But now a series of restoration projects is providing hope for increased coho and chum salmon and possibly steelhead trout as well as numerous other aquatic species.

In a story in the Kitsap Sun, Reporter Tristan Baurick described work this week on the Markwick property, where fish were removed in preparation for final channel excavation.

Here are some details (including photos) of various Clear Creek projects, as described in the state’s Habitat Work Schedule for restoration projects:

Washington Department of Ecology provided $2 million for the project. Kitsap County’s stormwater and roads programs each provided $500,000.

A single green crab invader has been found, the first in Puget Sound

A European green crab, one of the most dreaded invasive species in the world, has finally arrived in Puget Sound.

A single adult green crab was caught in a trap deployed on San Juan Island by a team of volunteers involved in a regionwide effort to locate the invasive crabs before they become an established population.

Until now, green crabs have never been found in Puget Sound, although they have managed to establish breeding populations along the West Coast — including Willapa Bay and Grays Harbor in Washington and the western side of Vancouver Island in British Columbia.

Coincidentally, I recently completed a writing project on invasive species for the Encyclopedia of Puget Sound, including a story about green crabs and the volunteer monitoring program.

Here’s what I wrote: “Puget Sound has so far avoided an invasion of European green crabs — at least none have been found — but the threat could be just around the corner….

“Green crabs are but one of the invasive species threatening Washington state, but they are getting special attention because of fears they could seriously affect the economy and ecosystem of Puget Sound. Besides devouring young native crabs and shellfish, they compete for food with a variety of species, including fish and birds.”

In Canada, one breeding population has been identified in Sooke Inlet near the southernmost tip of Vancouver Island. That’s about 40 miles away from Westcott Bay, where Puget Sound’s first green crab was found on Tuesday.

It is likely that the crab traveled to San Juan Island in its early free-swimming larval form by drifting with the currents, said Jeff Adams, a marine ecologist for Washington Sea Grant who manages the Crab Team of volunteers. This crab likely settled down in suitable habitat and located enough food to grow into an adult. Based on the crab’s size, it probably arrived last year, Jeff told me.

Finding a green crab in Puget Sound is alarming, Jeff said, but it is a good sign that the first crab was found by the volunteer monitors. That suggests that the trapping program is working. If this first crab turns out to be a single individual without a mate, then the threat would die out, at least for now.

The concern is that if one crab can survive in Puget Sound, then others may also be lurking around, increasing the chance of male-female pairing. The next step is to conduct a more extensive trapping effort in the area where the first green crab was found, then branch out to other suitable habitats in the San Juan Islands, Jeff said. The expanded effort is planned for the week of Sept. 11 and will include a search for molts — the shells left behind when crabs outgrow their exoskeletons and enter a new stage of growth.

Researchers and others who work with invasive species quickly recovered from their initial surprise at finding a green crab in Puget Sound, then got down to business in planning how to survey for crabs and manage their potential impacts.

Allen Pleus, coordinator of the Aquatic Invasive Species Program at the Washington Department of Fish and Wildlife, told me several weeks ago that if green crabs show up in Puget Sound, one idea would be to conduct an extensive trapping program to eradicate or at least reduce their population. First, however, the extent of the infestation must be identified. I expect that more extensive trapping will be planned next spring and summer to look for offspring from any successful mating in the San Juan Islands.

This video shows a green crab found in Willapa Bay on the Washington Coast.

Typically, green crabs are found in marshy areas, which are habitats extensively used by our native hairy shore crab. But Jeff tells me that some populations of green crabs seem to be expanding their habitat into more exposed rocky areas.

With roughly 400 suitable sites for the crabs in Puget Sound, invasive species experts are calling for everyone who visits a beach to look for green crabs and their molts. One can learn to identify green crabs from the Washington Sea Grant website. The volunteer trapping program is funded by the Environmental Protection Agency with a grant to Fish and Wildlife.

A public discussion about green crabs and how people can help protect Puget Sound from an invasion is scheduled for Sept. 13 at Friday Harbor Laboratories on San Juan Island. See Crab Team Public Presentation.

One orca is missing and presumed dead; another reported as ‘super-gaunt’

I have some bleak news to share about our Southern Resident killer whales, which normally frequent Puget Sound at this time of year.

J-14, a 42-year-old female named Samish, has gone missing and is presumed dead, while J-28, a 23-year-old orca mom named Polaris, may be living out her final days.

“Things are shaping up to be pretty bad,” said Ken Balcomb of the Center for Whale Research, who keeps tabs on the orca population. “J-28 is looking super-gaunt, and I would say she is within days of her death.”

The saddest part of my conversation with Ken this morning was to hear him say that Polaris’ 7-month-old calf would become an orphan and probably will not survive without his mother. That’s the typical outcome for an orphan of that age, Ken said, although there is a chance that the young male will be adopted by his grandmother.

The calf, J-54, is still nursing, but he is close to weaning, Ken noted. He is the newest calf born into the three Southern Resident pods and is part of the “baby boom” of nine orcas born between December 2014 and December 2015. So far, only one of those calves, J-55, has died.

After my conversation with Ken, the Center for Whale Research posted a news release about the death of Samish. Orca observers on the water have known that she was missing for some time now.

As of today, J pod was on its way out through the Strait of Juan de Fuca, no doubt searching for food. The chinook salmon run has been very low this summer.

“Historically, at this time of year, we would see nice little bunches (of orcas) swimming back and forth in front of the house,” said Ken, who lives on the west side of San Juan Island. But this year, the whales have broken up into small family groups and are traveling around in seemingly random patterns, presumably in search of whatever salmon they can find.

“Even the fishermen aren’t getting much this year,” Ken said.

To gauge a killer whale’s condition, researchers consider the overall shape of its body. Without adequate fish — primarily chinook salmon — an orca grows thinner as the body fat declines. As conditions grow worse, a depression develops behind the blow hole. This sunken condition — which Polaris has developed — is called “peanut head.” So far, none of the other animals have been observed in such a dire condition.

I’ve often been told by medical experts that when a killer whale loses weight it can be a sign of a major problem, such as a disease that makes them incapable of hunting to their normal ability. But a shortage of food can exacerbate the condition.

“We have been telling the government for years that salmon recovery is essential for whale recovery,” Ken said.

He blames the salmon decline on longtime mismanagement of wild salmon stocks — including damage to habitat, over-fishing and excess hatchery stocks in both Canada and the U.S. One of the quickest ways to increase the chinook population for these whales is to take out the Snake River dams, he said.

Rebuilding salmon runs on the Elwha River will help, Ken said, but the number of fish is small compared to the potential of the Snake River, which flows into the Columbia and produces salmon that can be caught in the ocean.

“I’m trying to get the marine mammal people to talk to the salmon people,” Ken said. “Fish have been a political problem for a long time, and we are not solving the salmon issue.”

Money spent on law enforcement to make sure whale watchers don’t get too close to the orcas would be better spent on education — specifically on educating lawmakers about the needs of salmon and killer whales, he quipped.

As of July 1 — the date of the annual orca census — the population of the three Southern Resident pods stood at 83. That’s the number that will be reported to the federal government. Since then, Samish has gone missing, so the ongoing count falls to 82, pending the status of Polaris and her son.

Samish was considered part of the J-2 (“Granny”) family group. Her living offspring are Hy’shqa (J-37), Suttles (J-40) and Se-Yi’-Chn (J-45). Samish was the grandmother to Hy-Shqa’s 4-year-old son T’ilem I’nges.

Polaris is the first offspring of Princess Angeline (J-17), who is still living. Her first offspring, a female named Star (J-46), is now 7 years old. J-54 is her second offspring.

Amusing Monday: Purple sea creature becomes an unlikely video star

Wait! Don’t touch that! It’s not a toy. It’s a living thing.

Researchers aboard the Exploration Vessel Nautilus were scanning the seafloor off the coast of California using an unmanned submarine when they spotted a purple thing that caused them to laugh with amusement.

“It looks so fake,” one researcher said. “It looks like some little kid dropped their toy.” (Watch and listen in the first video player on this page.)

They maneuvered the remotely operated vehicle Hercules closer and continued to laugh at the creature with eyes that looked glued on. Later, as the video went viral, this purple cephalopod — a class that includes squid, octopus and cuttlefish — became known to many people as the “googly eyed squid.” Since Aug. 12, more than 2.5 million viewers have clicked on the video.

This species, Rossia pacifica, is known to Puget Sound divers as the stubby squid or sometimes the bobtail squid, but it is not a true squid. See The Cephalopod Page by James Wood to understand the relationship among family groups.

This particular stubby squid was seen in early August on the seafloor about 2,950 feet deep off the California Coast. They can be found from throughout the North Pacific south to Southern California. They are found at many depths from coastal waters to inland seas.

The second video shows a bobtail squid spotted from the EV Nautilus in August of 2014, and the third shows a flapjack octopus from August of 2015.

Roland Anderson of Seattle Aquarium described early surveys in Puget Sound, where stubby squids were found in muddy sand at 11 sites between Seattle and Tacoma, including Elliott and Commencement bays. Check out “Field Aspects of the Sepiolid Squid.” (PDF 3.3 mb)

In a piece on “The Cephalopod Page,” Anderson writes, “One surprising thing recently learned about stubby squid is that they are found in polluted urban bays with highly polluted bottom sediments, such as the inner harbors of Seattle and Tacoma.

“There may be several reasons they can survive there. Deposition from rivers maybe capping polluted sediments. Their short life spans (just two years from eggs) may not allow them to absorb a significant amount of pollutants from the sediments. Another survival factor may be the stubby squid’s ability to produce copious quantities of mucus, which may protect it from the sediments like a thick Jello jacket.”

Reporter Stefan Sirucek of National Geographic News interviewed Michael Vecchione, a cephalopod expert at the Smithsonian National Museum of Natural History.

“It’s not an uncommon species,” he said. “They get all the way from scuba-diving depths down into the deep sea. If that is all one species, then it’s pretty broadly distributed.”

Vecchione said large eyes are fairly common among deep-see animals.

“They are funny-looking eyes, but I’ve seen other species of this genus that had eyes that looked very similar,” he said. “People were actually asking whether those eyes were photo-shopped in to make it look more like a cartoon or something. No, those are the real eyes. That’s what they look like.”

In low light, the big eyes help them hunt for crustaceans and avoid predators. In either case, the strategy is to remain still so other animals don’t notice it there, which can make it look like a child’s toy.

“My guess is it was probably frozen because of this big machine that was brightly lit up in front of it,” Vecchione said in the interview. “So it was trying not to be seen, basically.”

Amusing Monday: Local photographer captures a moment with an eagle

A Kitsap County photographer, Bonnie Block, has been named the grand prize winner in the 2016 National Audubon Photography Contest.

The winning photo shows a bald eagle swooping down on a great blue heron at the mouth of Big Beef Creek near Seabeck. Bonnie, a resident of Kingston, learned that her dramatic photo had been chosen from among 7,000 entries from all 50 states and numerous countries.

Big Beef Creek, not far from my home, is a favorite place for nature photographers and bird watchers, who visit in spring and early summer to observe eagles in action. That’s when the birds come to hunt for fish called midshipman before heading out to find migrating salmon. My wife Sue once counted 58 eagles at one time in that location. See Water Ways, June 18, 2010.

Bonnie describes how she prepared to shoot the critical moment in a story by reporter Christian Vosler published in the Kitsap Sun July 30.

Bonnie’s photo was mentioned during a CBS News interview with Melissa Groo, last year’s winner and a judge in this year’s contest. Melissa said a good photograph “freezes that instant that you can’t even see through the naked eye sometimes. Sometimes this behavior happens in a split second, but a photograph captures that unique moment for all of us to see.”

“Which is exactly what this year’s Grand Prize winner is,” commented reporter Brian Mastroianni. “I mean, the shot of the eagle and the heron is pretty incredible.”

“Exactly,” Melissa continued. “It’s that kind of confrontation, that pivotal moment where the eagle is landing and its wings are completely spread out, and you are seeing, obviously, some kind of confrontation. It’s just beautifully captured, technically and artistically speaking.”

A selection of Bonnie’s best photographs are on display this month at Liberty Bay Gallery in Poulsbo. You can also see some photos she has posted on her Facebook page.

The proper use of crab pots means extra crabs for the dinner plate

“Catch more crab!”

This is a campaign slogan going out to Puget Sound crabbers. It is a positive message, built upon the goals of:

  • Helping people avoid losing their crab pots,
  • Reducing the number of crabs that go to waste, and
  • Increasing the number of crabs available for harvest.

Crab

We’ve talked about the problems of lost crab pots that keep on catching crabs on the bottom of Puget Sound. About 12,000 crab pots are lost each year in Puget Sound, killing an estimated 178,000 legal-sized Dungeness crabs that would otherwise be served up for dinner. In January, I described some simple alterations to crab pots that allow crabs to escape when a pot gets lost. See Water Ways, Jan. 28.

Even more basic, however, are proven techniques that help people select equipment and place their crab pots so they don’t get damaged or lost in the first place.

The Northwest Straits Initiative, authorized by Congress in 1998, has been working on the problem of derelict gear for years, including the retrieval of thousands of lost nets and crab pots from Puget Sound. When it came to enlisting the public’s help in prevention, campaign organizers realized that everyone was on the same side, said Jason Morgan of the nonprofit Northwest Straits Foundation.

Crab2

“We previously focused on the doom and gloom of it, talking about so many crabs killed each year,” Jason told me.

Working with sociologists, campaign organizers realized that “the better way to reach people is not to talk about dead crabs but to say we want you to catch more crabs and keep your crab pots.”

The Northwest Straits Foundation has developed a three-year plan of action, including education for the public; improved communication among crabbers, vessel operators and government officials; and recommendations for improving regulations.

The plan was put together by a working group of 35 people involved in various aspects of crab harvesting, boat traffic and resource protection.

“It was a great collaborative process,” Jason said. “There was no butting of heads or anything like that.”

The “Puget Sound Lost Crab Pot Prevention Plan” (PDF 996 kb) states:

“Crab pots are lost for a variety of reasons. Causes for loss generally fall into three categories:

  • Vessel interaction (both recreational and commercial vessels);
  • Improperly configured gear, including improperly tied knots; and
  • Improperly placed gear.

“All these categories usually include a degree of user error, either on the part of the crabber, or on the part of the boater or vessel operator.”

The plan includes at least 25 strategies for reducing conflicts between vessel traffic and crab pots, reducing tampering and sabotage, improving crabbing equipment and pot configuration, and removing abandoned crab pots during non-crabbing days.

One of the interesting ideas is to require online registration for recreational crab endorsements on fishing licenses. Applicants would take a short quiz to make sure they know the rules.

Rich Childers, shellfish manager for Washington Department of Fish and Wildlife, said the various regulatory proposals in the plan are under advisement. One idea, which has proven effective, is to reduce the size of allowable escape cord (“rot cord”) that opens an escape hatch for the crabs to get out. Studies have shown that approved escape cord takes between 30 and 148 days to disintegrate, and most people use larger cord to last longer.

The time that crabs are trapped and dying on the bottom could be reduced if the rules were changed to require smaller cord. Any rule changes would include a grace period, Childers said, and it would be nice if crabbers could obtain the smaller cord for free.

With crab season underway, a series of videos on the theme “Catch more crab!” couldn’t come at a better time:

A longer video shows how to modify a crab pot to make sure that crabs can escape when a crab pot is lost:

Amusing Monday: Mermaids-to-be take lessons in special schools

A couple years ago, I was intrigued that a number of young women were making a living as professional mermaids. (See Water Ways, Jan. 27, 2014). Since then, the idea of becoming a mermaid for a day, a week or longer has caught on, with mermaid schools opening throughout the world.

Crimson Resort and Spa in the Philippines claims to be the first mermaid school in the world, but others were soon behind.

In New York, World of Swimming, a nonprofit corporation, inspires young people to become swimmers through lessons, swimming camps and other activities.

The first short video on this page features young mermaid swimmers accompanied by music as they swim about by swishing their tails. In the second video (also below), ABC News reporter Sara Haines takes the plunge in a first-person report to see what it is like to become a mermaid. The piece made the airwaves on Good Morning America.

In Vermont, reporter Sarah Tuff Dunn goes to mermaid school for the online publication “Seven Days” and is thoroughly enchanted after putting on her mermaid tail with its built-in swim fins.

“I felt the tail rise as if magically,” she wrote. “I released my hands from the wall and began to swim … like a mermaid. A doggy-paddling mermaid, mind you, and one who momentarily panicked when she realized she couldn’t scissor-kick her legs.”

Sarah, who soon catches on to swimming like a dolphin, discusses the risks of drowning with one’s legs tied together, and she explains why mermaid schools tend to emphasize safety.

What I find interesting about this mermaid trend is that children are getting excited about swimming. Being a mermaid or merman expands their confidence as they hold their breath under water for longer periods of time while building up their muscles for what could become a lifelong interest in aquatic sports — or at least some basic survival skills.

For those who operate or would like to operate a mermaid school, there is a newly formed International Mermaid Swimmers Instructors Association.

Amusing Monday: Cats can be trained to enjoy water and other things

I grew up with cats and have lived with cats for most of my life. I can’t recall that any of my feline friends were fond of water. But then nobody I know has ever taken the time to teach them to surf on the back of a dog, ride the waves with a human or even learn the basic command to “stay.”

These things are exactly what long-time dog trainer Robert Dollwet has done after deciding he wanted to train cats. After moving from California to Australia in 2010, Robert went to a local animal shelter and adopted a lively kitten he named Didga, short for Didgeridoo. As he proceeded through the training, Robert began sharing his methods on a YouTube channel he named “CATMANTOO.” Later, he added another kitten, Boomer, to his family.

The first video on this page shows Didga performing a stunt that Robert calls “Ice surfing.” That’s because the dog (who belongs to a client involved in dog training) is named Ice. Robert says many of the feats shown in his videos take weeks or months for the animals to learn.

“Please don’t try the things you see at home,” he says in a note attached to the video. “I’d feel bad if your cat was hurt or forced into doing something they don’t want to do. Watch my tutorials to learn how to teach your cat.”

The second video, released in April, shows Boomer riding on a surfboard on a river, as Robert gently paddles around.

“We’ve been doing this since he was a kitten,” Robert writes in the notes. “I gave him lots of food while he rides on the surfboard. He’s 11 months now, and he is so comfortable, it’s about that time to take his surfboard riding skills to the next level — by actual surfing on a wave in the ocean (with life vest, of course). Stay tuned.”

The third video is an amusing story called “Didga Dreams BIG,” which actually shows off this cat’s repertoire of tricks and stunts. I like the way Robert demonstrates his cats’ abilities by telling little stories in some of the videos — such as Didga’s skateboard trip around the beach town of Coolangatta, where he lives in Australia. See “World’s Best Skateboarding Cat!”

You can check out the helpful YouTube tutorials on CATMANTOO to learn some basic cat skills that I believe might be helpful in daily life:

Canary rockfish likely
to be removed from Endangered Species List

One of the three species of rockfish listed as threatened or endangered in the Puget Sound region is about to be pulled off the Endangered Species List, following recent scientific findings.

Genetic studies carried out with the help of fisherfolk from Kitsap County have determined that canary rockfish are not a discrete population from those found off the Washington Coast. An official comment period on the delisting is open until Sept. 6, as described in the Federal Register.

I first discussed early evidence of this genetic finding a year ago. Kelly Andrews, a genetics expert with NOAA Fisheries, confirmed that limited genetic samples of canary rockfish from coastal areas appeared no different from samples taken from Puget Sound. Kelly wanted to review analyses from additional samples before drawing firm conclusions. See Water Ways, June 18, 2015.

Removing canary rockfish from the Endangered Species List will have no effect on yelloweye rockfish, listed as threatened, or bacaccio, listed as endangered. The change also is expected to have no immediate effects on fishing rules, which are designed to protect all rockfish in Puget Sound.

Rockfish are considered an important part of the Puget Sound ecosystem. Understanding the causes of their decline and finding ways to rebuild their populations could help with the recovery of a variety of other marine species, experts say.

A five-year review (PDF 15.1 mb) on the status of the three species of rockfish was due last year, but it was delayed until April of this year to include the new genetic information. In addition to a proposal to delist canary rockfish, the report discusses the difficulty in gathering population data. The authors were able to report:

“The data suggest that total rockfish declined at a rate of 3.1 to 3.8 percent per year from 1977 to 2014 … or a 69 to 76 percent total decline over that period. We did not find evidence for subpopulations with different population growth rates.”

Those involved in the scientific effort expressed appreciation to the anglers who went out with them to track down rockfish and take fin clips for genetic sampling. The effort also included information from the Washington Department of Fish and Wildlife, where researchers surveyed rockfish areas with divers and remotely operated vehicles.

“Without the expertise of experienced fishing guides, anglers, and WDFW’s rockfish survey data, it would have been difficult to find the canary rockfish and yelloweye rockfish to collect the fin clips needed for the study,” according to a question-and-answer sheet from NOAA Fisheries (PDF 534 kb).

The local fishing experts were able to take the researchers to the hotspots where rockfish have always been found.

During the sampling, fishers were careful to release the rockfish with “descending devices” to get them safely back to deep water, where they reside. That is a technique recommended for all anglers who catch rockfish while fishing for other species. For details, see “Bring That Fish Down” (PDF 673 kb) by California Sea Grant and “Protecting Washington’s Rockfish” by WDFW.

Among those helping with the survey were Ray Frederick, a longtime leader in the Kitsap Poggie Club, a local fishing group, and Randy Jones, a charterboat operator from Port Orchard.

Ray recalls catching rockfish decades ago while fishing for salmon and other fish. “I considered myself lucky if I caught a rockfish and brought it home, because they’re really good eating,” Ray said in a story written by Ed Quimby, a former NOAA writer. “I prefer salmon,” Ray added, “but my wife likes rockfish better.”

Efforts to develop a recovery plan for rockfish continue for yelloweye rockfish and bocaccio as required by the Endangered Species Act. Details can be found on NOAA’s webpage “Rockfish in Puget Sound/Georgia Basin.”

Amusing Monday: Students produce videos about climate concerns

How high school and college students view climate change shine through clearly in new video productions submitted in a contest organized by the University of Washington School of Environmental and Forest Sciences.

The school is a unit within the UW College of the Environment. This is the second year for the contest, supported by the Denman Endowment for Student Excellence in Forest Resources.

Contest rules describe climate change as an issue that unites all the research interests within the school, topics that include sustainable forest management, biofuels, wildlife conservation, landscape ecology and plant microbiology.

“Much of the responsibility for finding sustainable solutions will fall on the younger generations,” the rules state. “That’s what inspired us to host this video competition — to spread awareness and hear your voices on the issue.”

The first video on this page is the 2016 first-place winner in the high school division. The second video is the 2016 first-place winner in the college division. The third video is last year’s first-place winner in the high school division.

Judging was conducted by a panel of climate scientists, artists and filmmakers. First-place winners received $5,000; second-place, $1,000; and third-place, $500.

Here are this year’s winning videos, with links to the top three in each division:
