The culprit
From ensenada.net
Saxitoxin, the cause of the closure by red tide
It is unusual in Gulf of California
Article posted January 19, 2015
by Elizabeth Vargas
In the coming days is expected that the ban imposed by ISESALUD by the Federal Commission against Health Risks bivalve molluscs of the Gulf of
California, following the detection of a red tide on January 16 nancy.
The Secretary of Fishing in Baja California Matias Arjona said the ban by the red tide is exclusive to bivalve molluscs, which in this area includes
geoduck clam and chocolata exclusively.
In this case the red tide dinoflagellate is derived from a microorganism which produces saxitoxin, which is a toxin that had rarely been observed in
the Gulf of California.
He said the ban determining concentrations were detected on 16 January 2000 to 700 micrograms per kilogram when the normal concentration is 800.
Three days after the January 19 sampling showed a significant decrease in 1000 100 micrograms to meet this Monday at 1600 micrograms.
When it normal that are 800 micrograms be the same health authorities who determine the lifting of the ban in the area.
He stressed that there are no more bivalve molluscs of commercial interest in the Gulf of California, as in the Pacific region where production is
important and involves many species.

 I thought the sea of cortez was famous for its red tides, hence the
"vermillion sea"?

The "Vermillion Sea" analogy was due to the mass abundance of Krill in the waters which are now yet another casualty of overfishing by man. Many
reports of 'carpets of red' were attributed to Krill. Also, the late-winter early-spring halfbeak and needlefish roe has the same color, and is
bio-luminescent.
If this was a true 'Red Tide' event, I hope there are follow-up studies to confirm. It's unusual, but not impossible.

Update provided by Kat
Ive posted this on Kats Korner but to get it around, please share
Here's the latest scoop from the Secretary of Heath in Baja
Good afternoon, this is a statement that we received from the Government of the State of Baja California, where we explained the reasons why the
decision of close all the fishing and the sea for two days also the general fishing in San Felipe in precautionary signal was taken to analyze the sea
and its products, and see if there was any risk in the eating of local products or swim in these waters, which allow through this result in our favor,
please spread it and pass it with your contacts and social networks so this helps to reverse the negative propaganda that occurred in previous days
refereal to Red Tide and also to alleged pollution of the mine, and that according to results of the analysis reveals that no such pollution and just
need to await the results of the analysis to clam species grown in the region to give a general opinion. Meanwhile please dont eat or market any type
of clam till we have the professional analysis done. Thank you very much."

Mass Death of Seabirds in Western U.S. Is 'Unprecedented'
http://news.nationalgeographic.com/news/2015/01/150123-seabi...
= = =
On the Facebook page for the San Felipe South Campos, a lady posted the following. She rode the beach for 15 km and this is her report. "My
findings are; 3 whales, 1 seal, 34 dolphins and 293 birds." Such a tragedy that we are witnessing with the Sea of Cortez and the dead sea life. I
wonder if we can get any opinions other than the rumors that are flying about the mine and the red tide. Anyone out there know what is happening, for
real?

Could the red tide be explained by the introduction of nitrogen fertilizer from the recent release of water into the Colorado River Delta?
Perhaps when releasing water into the river it should be done a little at a time rather than in a massive flood. This would allow for nature's
filtration system (reeds, sunlight, oxygen, algae) to attenuate the slug of pollutants that has accumulated in the dry river bed before it is all
washed in to the sea.

Has the Colorado really been flowing into the gulf the past year, with the so called drought making reservoir levels dangerously low?
Was fresh water released last year and that is what caused the water shortage?
Wasn't flushing water into the gulf supposed to be a good thing for marine biology and the complaint has been the fish and mammals have suffered
because of the lack of water flowing in the Colorado?

So called drought? You don't give up do you. Although according
to one here, the Ca. drought isn't bad in no. San Diego County,
must be the only place in Ca. is isn't. Quit embarrasing yourself,
do a little reading

water was released to the Colorado River Delta in a "pulse" one year ago, in Mar 2014
http://news.nationalgeographic.com/news/2014/03/140322-color...
not sure if any of it reached the gulf or if have been any releases since then. Sometimes it is not so simple to reverse 100 years of environmental
degradation of a water system, there can be unintended consequences years later. As far as the drought, it has not affected me at all, I can still
use all the water I want. the real drought is in the river systems that used to support fish nurseries.

The amount of rainfall is not that different and not the lowest from the recent past, but because water is released from reservoirs (built so people
could have water when it doesn't rain) to benefit some fish, at the expense of farmers needs to grow food, and the rest of us to live, makes it a
"so-called drought". The word 'embarrassing' has two s's fyi.
http://www.laalmanac.com/weather/we13.htm
115 years ago, we had less rainfall than in 2012, and the year before we had 5 inches over the average of the past 135 years. Remember all the bridges
south of Ensenada being washed out in 2010???
People have short memories, and then there are people who have a political agenda to bury the historic facts of rainfall in Southern California, in
order to get funding or power from the citizens.

Without your hated funding, there would be no dams, and probably no SoCAl as you know and enjoy it.
