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.

not good news. this is the first I have heard of this.

"foot withering disease"

Whale-ista - 1-27-2016 at 08:27 PM

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). "

I have half-a-foot-withering disease.

I do not think it's from bacterii..... :no:

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.

***ushima radiation ??? remember that little accident in Japan that is still pumping 330 on a day of spent radiation in the Pacific

A bit premature to blame climate change

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.


barniclebob - 1-28-2016 at 08:39 AM

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.

BajaBlanca - 1-28-2016 at 11:30 AM

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.

:lol::lol: 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


BAJA.DESERT.RAT - 1-28-2016 at 12:23 PM

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 ?

BIEN SALUD, DA RAT

shari - 1-28-2016 at 12:23 PM

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.

willardguy - 1-28-2016 at 03:11 PM

850 peso's a can.....I bet they're taking this seriously!:o

If I am not mistaken, our own Baja Gringo is in the forefront of abalone development and preservation.

What sayeth thou, Ron?

DFG did contract with the farms for restocking and did know that stock from New Zealand was to be used . Whitering foot first started in the early 1990s . it survives in the water collum for years and spreads infecting more during El Nino warm water years

The best way to get a hold of Ron is through the TALK BAJA forum on Facebook.

Free diver Brian knows what's up..

Withering foot syndrome is very well documented.. It nearly wiped out the black abalone in the Channel Islands.. Only a few strongholds of this species remain at the islands.. The whites (sorensons) are gone.

The pinks and reds are making a strong comeback in certain areas of the channel islands.. So much so, there was a chance they were going to open up a limited commercial harvest several years ago.. Didn't happen. iMO they should move some of the strong populations into the oh so precious closures they have now..... They won't listen to local fisherman though. Never have, never will

Two points.

#1 I am not on Facebook, as are millions of other folks. I will spare you of the details as to why I think Facebook is much more a negative than a positive foe society.

I was a regular poster on Ron's Talk Baja, but refused to join Facebook just to continue.

#2 Ron is still a Nomad and checks in here regularly,
