The Turtles of the Sea of Cortez have always got my attention. I have a Hawksbill hanging on my office wall.
Years ago while living at San Nichalos I ate Turtle on several occasions as at that time it was not Illegal, if fact they were still serving it at the
Bismark 2 in La Paz.
later I decided I would not again eat Turtle and have not since that time.
I flound that most of the time i caught a Turtle stranded on the Beach that there was a problem with the Turtle, I would put them back in the water
but later would find them Dead floating nearby. There are still lots of things we do not know about Sea Life.
I have much confidence in the Sea of Cortez and think that it will survive.

We ALL Hope
For the Sea Turtle population to thrive to the point where they're not only no longer in danger, but plentiful.
They were, after all, GREAT tasting.
It would be nice to see them on menus again.

Any sign of ramuma at those beaches?
After all, he has shown so much concern for these animals.

Yesterday we found 6 dead loggerback turtles between Asunciona and Los choros beach and lot of cormorants dead and sick too...the one we rescued died
shortly after. It will be interesting to find out why they are dying. On Facebook they are saying it is a natural phenomenon that happens every 3
years or so and this year it is our turn....while I sure love the hot water for swimming, the coops worry about the abalone and lobster stocks.

Les remembered that some years ago Punta Abreojos lost much of their lobster in such a hot waters year, but for some reason, we, only 10 miles north,
did not lose ours.
I do agree that there is an element of survival of the fittest, but it is sure sad to see turtles dying when their numbers are just not up enough yet.
I personally have never tried turtle.

Lobsters in Hot Water
Now, There's a Tasty image.
Speaking of tasty critters, has anyone ever tasted Dolphin Steak ?
On the one hand, I've read that their meat doesn't taste good and on the other I've read that fishermen who've killed them as by-catch and
eaten them love the taste.
??????
I suppose we'll never get to know firsthand.
Since there's only 102-103 days left for us all, anyway, it doesn't matter.
We're ALL in HOT Water, right ?

Guerrero Negro Verde reports on Facebook
This great group in Guerrero Negro just posted a photo of a decomposing turtle carcass. It has a large bolus, a tumor, on its neck. Apparently this
tumor has been shown to be the papaloma virus which is what probably killed this creature.
Here's the translation of their post and explanation:
"This is a turtle stranded on the shores of the North Pacific, the lump on the side of his neck papillomavirus. Studies continue to determine the
health of the turtle population, whether or not it can be infectious to humans (do you want to risk it?), This species is closed and is therefore
forbidden to marketing and the reason is very simple, is in danger of extinction.
All bodies have been found stranded buried to avoid health risk to humans and other predators (coyotes, etc..). Samples have been taken from some
turtles. This particular specimen was found off the coast near Bahia Asuncion."

some friends of ours went along the estero dunes from punta abreojos to the entrance of the lagoon and counted 24 dead turtles. That stretch is just
11 miles.

Herpes Virus
Again from Guerrero Negro Verde, the common denominator and probable cause of the widespread death of these gorgeous creatures. The link, in Spanish,
is here: http://on.fb.me/SBLJbP.
The translation into English below:
Tumor growth in the tissue of the skin is called fibropapillomatosis. In humans these increases are due to the presence of a virus that has different
manifestations ranging from small to large growths warts in different organs.
In recent years it has been observed, with increasing frequency, the presence of these growths on the skin and shell of sea turtles. No one knows for
sure what causes them but we have seen that is related to the presence of a virus in other animals, so it is very likely that turtles also have this
origin. However, it also might be related to marine pollution, as a turtle whose immune system is depressed may be more susceptible to disease.
It is likely that sea turtles eating contaminated algae produce a growth of herpes virus that is transmitted to the soft organs: eyes, skin, and other
internal organs, producing fribropapilomatosis.
Early in the disease, the virus produces spots "salt and pepper" in the skin, dark and light spots on the skin of the loggerhead, that after a year
they become tumors.
The herpes virus is transmitted by contact with secretions from the eyes (tears and crusting), nasal (mucus), or genitals. But also by contact with
blood or open sores can spread the disease.
In turtles, it is likely that the disease will spread in the early stages when only external lesions are noted. In mammals the herpes virus produces
lesions that are seen as vesicles on the mucous membranes of the mouth and genitals, but also can occur in the eyes and even the skin. The virus can
cause abortions and neurological disorders producing severe pain in parts of the body and even paralysis.
A surprising feature of concern in the case of sea fibropapillomas is that the virus is very stable in the salt water, so it is likely to be present
in the seawater around the turtle, particularly when confined indoors therefore no direct contact is necessary for the infected turtle exposed to the
virus and for this reason, the handling of sea turtles must be done with extreme care and never with bare hands. [1]
