It's Really All About the Food Chain, Isn't it?

I will be attending a "gear Down" session for Marine Naturalists sponsored by the Whale Museum. The workshop is a continuing educational training for naturalists already working in the field and graduates of the Marine Naturalist Training Program. Since the news this year has been so focused on the decline of the Southern Resident Orca population, the program will include a discussion about salmon recovery efforts by Lead Entity Barbara Rosenkotter, and an update on the health of the Southern Resident orca population by David Ellifrit of the Center for Whale Research. We'll also be covering Acceptable Risk (Contaminants in the marine environment) and Threats from Underwater Sound. I really expect this to be not only an interesting day but hope to come back with thoughtful ways to address the issues affecting the orcas. I will most certainly update the blog this weekend and share the highlights.

In the interim, another opinion piece about the bottom line- food.

We have to be salmon tough | Being Frank

We need to be as tough as the salmon themselves if we’re going to see their recovery.

South Fork Nooksack River native spring chinook are almost extinct and need our help. It wasn’t long ago when about 13,000 of these early-timed chinook came back to the river each year. They were the first salmon to arrive each spring, feeding Indian people after long winters, when no other salmon were in the river.

Spring chinook have a much tougher journey than other salmon because they spend more time in fresh water before spawning. They are especially sensitive to poor habitat conditions in the river.

Time has not been kind to salmon habitat in the South Fork Nooksack. The loss of trees and other plants along streams has removed important shade and reduced the source of wood needed for in-stream fish habitat. Spring chinook need deep, sheltered pools of cool water for their extended rest before they spawn. Water that is too warm can result in disease, reduced salmon egg survival and even death.

This summer, to give the river the building blocks it needs to restore degraded habitat, both the Lummi Nation and the Nooksack Tribe built specially engineered logjams in the South Fork. Over the next few years, these logjams will help create the deep pools that young and adult salmon prefer.

While we are fixing the habitat, we also have to make sure that we are protecting the unique genetic traits of these fish. The Lummi Nation and the Nooksack Tribe are working with the state Department of Fish and Wildlife and the National Oceanic and Atmospheric Administration on an important program to raise juvenile South Fork Nooksack River chinook in captivity and spawn them. Their offspring will be released in the river to migrate naturally and return as adults a few years later.

Our goal for this stock is the same for all wild salmon stocks: to recover their populations to levels that can again support harvest. By taking these naturally spawned juvenile chinook into protective custody, the tribes are safeguarding their future.

The path to recovery takes a side-by-side approach of boosting numbers now while also fixing the habitat so the river can support a healthy, productive population. I’m proud that the tribes are taking a leadership role in both areas.

Salmon face great challenges during their life journey. With their numbers falling, we have to work harder to help them on their way. As long as they continue to swim upstream, so should we.

Orca Calf Found Dead On Henry Island

Sadly enough the news that was posted August 4th was not what many want to hear- the San Juan County Marine Mammal Stranding Network has recovered a body of a dead orca calf on the beaches of Henry Island.  While it was originally sighted on July 26th, the fetus was not reported to the Network until August 1.   In the meantime, the body was scavenged and was in an advanced state of decomposition when researchers arrived on scene. 

According to Amy Traxler, who runs the Network, “A newborn killer whale calf is usually 7 to 8 feet long and 300-400 pounds,” while this carcass was approximately 5 feet long with an estimated weight of 70-80 pounds, so it’s likely this calf was aborted.”  The placenta was lying next to the calf when originally discovered, she said, and it is believed the calf was born prematurely. Cause of death, as well as whether it was a member of a resident or transient pod, is expected to be determined in a necropsy being conducted by Dr. Joe Gaydos, the Stranding Network’s veterinarian and regional director of the SeaDoc Society , a research institution affiliated with the University of California-Davis.

A recent paper Gaydos presented to the International Whaling Commission suggests that an average of seven killer-whale carcasses are found around the world annually, making every killer whale stranding a rare opportunity to learn more about the biology and diseases of this species. Researchers will now try to conduct a necropsy to try and determine the cause of death as well as attempt to determine if this calf is, indeed, an offspring of the endangered southern resident community of orca whales.  At issue will be the amount of decomposition and whether or not there are any viable tissue samples to be found.  I actually assist in necropsies with Joe and Amy- and see firsthand what a loss a decomposing body can be to scientific efforts.

To respond to marine mammal strandings in San Juan County, alive or dead, please call 1-800-562-8832 and leave a message with your name, phone number, location, and other pertinent details of the stranding. You will be helping to better understand and protect the region’s marine mammals.

Whale of a Purpose!- A Fun Blog to Check Out!

Whales, whales, whales!  The kids are back in town!  Jeanne Hyde, who runs the Orca Adoption Program at The Whale Museum- has a fantastically fun BLOG- with a twist! Jeanne writes:


"I believe that my purpose is that of inspiring others in their lives, because of my enthusiasm about things I am passionate about. It's not something I do, it seems to be what others feel. COME WHALE AWAY WITH ME!! Sharing my killer whale encounters with you. Sometimes they are from a boat and sometimes while I'm sitting along the shore. I'll bring the whales to you no matter where you live. Enjoy!"
