The abalone aregetting sick!
http://www.ensenada.net/noticias/nota.php?id=43635
Sorry but I cannot translate to Nomad on my computer.
Basically it comments that the abalone are sick, weak. Perhaps it is due to warming waters-climate change?
The abalone seem to be seeking deeper, cooler water.
DENNIS help me-translate please.

Roughly:
A bacterium, which is currently under investigation by scientists has decimated in recent months abalone populations off the coast of the Mexican
Pacific Fisheries confirmed the Delegate in Baja California Oscar Baylón.
The bacterium is a variety of "vibrio" that affected the abalone, both wild and cultivated, which becomes vulnerable by warmer water and lower the
defenses of mollusk attacks the bacteria causing growth to stop.
"If one were to equate with human suffering, it could be something like an opportunistic bacteria that take advantage of the flu to attack a person
who is at that time low defenses and leave permanent sequelae."
So far this problem has resulted in abalone, shellfish many try to go to the deeper and colder waters which has made fishing more complicated healthy
molluscs.
The problem began to present from about two years ago, and the first thing noticed is that many fishermen went to the deeper waters.
They found that they could be sick because abalone is weakened, thinner and loses the ability to grow.
When the fishermen saw it and confirmed that lacks the necessary consistency return it to the wild.
The researchers then found that it was an opportunistic bacterium that was what attacks.
Currently explained Baylon, you are about to start a series of meetings convened by the National Committee on Fisheries and the Ministry of Fisheries
of the State, which will seek to bring together expert researchers, entrepreneurs, cooperatives and farmers abalone on the peninsula, as is endemic to
this region.
It aims to prepare a strategic document to establish policies and actions to restore abalone populations throughout the peninsula.
It is the last institutional opportunity to agree specific actions to recover populations of this species.

"foot withering disease"
It's called "foot withering disease" and it's a terrible threat to Pacific abalone fisheries. It's what helped wipe out the local abalone in SoCal
decades ago- they never came back.
Google the name, or visit: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3854573/
"An intracellular bacterium Candidatus Xenohaliotis californiensis, also called Withering-Syndrome Rickettsia-Like Organism (WS-RLO), is the cause of
mass mortalities that are the chief reason for endangerment of black abalone (Haliotis cracherodii). Using a real-time PCR assay, we found that a
shore-based abalone farm (AF) in Santa Barbara, CA, USA discharged WS-RLO DNA into the ocean. Several other shore-based AFs discharge effluent into
critical habitat for black abalone in California and this might affect the recovery of wild black abalone. Existing regulatory frameworks exist that
could help protect wild species from pathogens released from shore-based aquaculture.
"At first, the die offs were attributed to an El Niño Southern Oscillation event (Davis et al., 1992), but the continued spread of mass mortalities
was more indicative of an infectious process (Lafferty and Kuris, 1993). Pathologists discovered the cause: a novel intracellular bacterium Candidatus
Xenohaliotis californiensis, or Withering Syndrome Rickettsia-Like Organism (WS-RLO; Friedman et al., 2000). "
\"Probably the airplanes will bring week-enders from Los Angeles before long, and the beautiful poor bedraggled old town will bloom with a
Floridian ugliness.\" (John Steinbeck, 1940, discussing the future of La Paz, BCS, Mexico)

We can thank California department of game / wildlife for the withering foot disease In thier efforts to restore the abalone population exposed the
wild stock thru abalone farming . DFW killed more abalone than pochers ever would have. With out good science they wiped out the black abalone. Never
bring in a untested foreign breeding stock.

The state agency ran the abalone farms?

I believe the warmer waters help the bacteria to breed. THose stocks in cooler waters are not as susceptible.

A similar thing happened a few years ago to sea stars in the eastern Pacific. The legs withered and fell off, thousands died. This was taken in
November of 2013 in Morro Bay. The disease has apparently passed, even with the significant increase in water temperature, the sea stars I see all
look healthy now.

The green gob extended from Mexico to Alaska for 2 years now and killed bird life ,whales and many other fish including star fish here in the north. I
suspect radiation as well and warmer water but none of the scientists will admit to radiation being the cause

My husband is an abalone fisherman and in our village of Bahia Asuncion, they do abalone evaluations every few months and so far so good still here.
They count, measure, weigh and take samples for analysis to determine the quotas which are quite low so as to have a sustainable yeild in the future
and alot of money is spent on a vigilancia program to deter poaching.
Bahia tortugas had to close the season last year and not harvest abalone. One of the problems was that the warm sea temps killed off all the bull
kelp which abalone eat so they are not as fat as usual but they are still relatively healthy here.
Most fishing cooperativas have labs where local seed is stored and grown in case of die offs so they have seed to replace them. Our villages here on
the central coast depend on this fishery economically.

That's an outstanding post Shari.
Local solutions applied to real time issues can be very useful. If there is a broader reason for the problem, it will be beyond their influence or
control.

that was informative, Shari, and I can attest as well that the abalone and lobster as well as fish is controlled and quotas are made based on the
results.
We have a full on abalone farm that is growing the abalone from tiny tots on up. I think the process takes 5 years. It is open to anyone to visit
and it sure is amazing.

 Good
Hijack but on a serious note the inbreeding amongst followers of Islam has resulted in many cases of double foot growth instead:

Hola shari & baja blanca,
it is wonderful news that you are doing this research and storing the abalone seeds just in case. is this privately funded or a government program ?
thank you for the info.
BIEN SALUD, DA RAT

hola,
i hope this is not a thread hijack.
is the warm water affecting the aquaculture farms in the ensenada bay and san quintin and any other areas that this type of farming is being done.
also the shrimp farms ?

the fishing cooperativas are taking this initiative and most likely have some government support as well. There are alot of serious concerns about the
future of fisheries here as the town depends on it. The changing climate conditions and overfishing of sardines mean declining stocks that equal
declining incomes as well so people are thinking about what else they can do in the future.
