Salmon Shark With Strange Parasites Rescued By Seaside Aquarium

Fri, 10/3/2008 - 8:09 AM

By Keith Chandler

Seaside, OR - It was something the crew at Seaside Aquarium had never seen before. A salmon shark washed up in the Cannon Beach area Wednesday, still alive – which alone was a bit odd. But this salmon shark was covered in a dense layer of parasites in an unusual way.
 
The Seaside Aquarium is part of the Marine Mammal Stranding Network for the north Oregon coast, responding to baby seals that have wandered up, molting seals, injured sea lions and the like. But they also remove corpses of creatures that spill onto the beach from the tide.
 
Aquarium manager Keith Chandler said the shark was still living when they found it about 10 a.m. Wednesday. An hour and a half later it was dead, but first Chandler and others tried walking the four-foot salmon shark around the tank in order to get oxygen into its gills.
 
Salmon shark bodies washing up on shore are a bit unusual, but one that’s still alive is a bit more rare. What was really unusual about this shark was the number of parasites covering it, and the fact staff could not identify the type of parasite.
 
“I have never seen this many on a shark,” Chandler said. “And I’ve never seen this kind of parasite either. We don’t know what it is. He wasn’t a healthy specimen by any means.”
 
They have begun seeking input from other marine experts around the northwest.
 
This sickly condition, Chandler said, could have had something to do with it washing on shore.
 
This was the fourth salmon shark found by the Seaside Aquarium in the last six weeks. They have been showing up in the fall and late summer months in recent years, with apparent increasing frequency.
 
“It used to be we’d see one every other year,” Chandler said. “But I think that it’s not so much that there are more out there now, but rather that people know who to call. The education about that has gotten better lately, with the media and so on.”
 
2007 was a wild year for salmon shark strandings, as over 20 bodies were found on the upper half of the Oregon coast last year. Chandler said it’s likely the salmon sharks are closer this time of year, following salmon or other food sources.

Irresponsible Board of Management Thu, 11/5/2009 - 9:20 PM — latino boy

Maybe , just maybe The Toronto Zoo Board Is In The Middle Of A Financial Crisis And There Is No Place To Go But To City Council like a wayward son go to Mom and Dad for more money...

Although it was made clear by Shelley Carroll (the City's Budget Chief) that the Toronto Zoo has to behave more financially responsible, perhaps the problem is that there is no place else to go. The $250 Million fund-raising plans are a pipe dream (especially after firing the Zoo Foundation), it is not possible to raise admission prices any longer (or face a significant drop in attendance) and the "junkets" (especially to China for the Giant Pandas) by members of the Zoo Board can not be cut significantly for any reason. In other words, there is no place to go but City Council. What a crock! The Toronto Zoo Board needs a reality check, as it has become clear that they do not understand the problems they are facing. Perhaps the thousands of free Zoo passes given to Councillors on the Zoo Board could be cut to zero, perhaps the Zoo Foundation could be re-instated, and perhaps a citizen's advisory committee could be formed to provide much-needed guidance to the existing members of the Board.

This is Proof positive

that citizens should have more direct say in the budget process. Line item veto by a citizen's budget committee might get the desired cuts we must attain. The citizens of Toronto should stand with one voice that we just won't allow a property tax increase this year.

Ethyl Mercaptan Mon, 11/2/2009 - 2:27 PM — Mercaptan

I would be quite interested in any reference you might have to the presence of ethyl mercaptan in carrion.  Most literature indicates that dimethyl sulfide and methyl mercaptan are the sulfur containing entities involved.  I had also thought that vultures, like many carrion eating and inhabiting species (flies, etc) were attracted to the rather bad smell of the nitrogenous materials (cadaverine, putresceine, etc) produced during decomposition.

Very nice ant exhibit! I wrote a small ant farm post with a reference to your article.

Happy Birthday, Boomer! Sat, 9/12/2009 - 7:26 PM — redapes

You are a great ambassador for your cousins in the wild, Boomer!

Orangutans are critically endangered because of rapid deforestation and the expansion of palm oil plantations.

If nothing is done to protect orangutans, they could be extinct in just a few years!

Venemous snakes? Fri, 9/11/2009 - 9:18 AM — Kyle Bradley

What is it with people that want to exterminate venemous snakes? If they weren't an integral part of the food chain and ecosystem, they wouldn't be here! Evolution and natural selection has chosen them as survivors! The fact that they are "harmful" to humans is only a result of humans encroaching on their territories and habitats. Be mindful of your surroundings and situation and you can safely live with the so called "harmful" species that we share this planet with!


Local wildlife day Sat, 8/22/2009 - 5:41 PM — Devon eco lodges at Wheatland Farm

Good luck with the event. We have some fabulous wildlife in Devon that's really worth celebrating. We recently had a botanical survey of our small  Devon nature reserve, which recorded more than 180 species in about 3.5 acres. And even more amazing was the depth of local knowledge the visiting naturalists had to share - on everything from obscure moths to lichens.

Sadly, a lack of common sense is the trend Sun, 8/9/2009 - 7:57 PM — eliewriter

What is sad to me is the lack of common sense regarding venomous snakes that seems to becoming more commonplace.

It has become trendy for government agencies to defend venomous snakes, saying they kill rodents, etc., but non-venomous snakes also kill rodents. I have not heard one logical argument as to what a venomous snake contributes to an ecosystem that a non-venomous snake doesn't.

Any non-biased biologist can affirm species extinction has always happened naturally. It's common sense to kill a venomous snake, rather than let it continue breeding and increase the potential for harm.

The unfortunate consequence of naturalists defending venomous snakes is they make them appear so necessary and harmless that both people and agencies--hospitals, for example--do not expect or prepare for snake encounters.

It's doubtful that many hospitals near the snakes stock the expensive antivenin. Governments should help fund snakebite treatment rather than fund snake protection.


Skype Usage Fri, 8/7/2009 - 5:02 PM — Shawn

Very cool and novel way to use Skype. Glad to see that people are thinking outside the box with its collaborative application. If it's not too late, you may want to submit this to Skype as a good use of their software for the Skype in business contest they're running.

Word Oceans Day - June 8 Thu, 6/4/2009 - 11:58 AM — The Ocean Project

And don't forget to "Wear Blue and Tell Two"
  

Another great way to celebrate World Oceans Day is to wear blue in honor of the ocean and tell people two things they likely don't know about the ocean and two ways they can take action. For more Information check out this website:
