Will not “transform” global production but a useful tool to support shrimp industries continued growth. While checking on viruses cheaply it will not mean shrimp farmers can relax. Not a silver bullet and look what happened recently with disease in UK imported shrimp PL’s from USA – under SPF paradigm and surely imported with appropriate health certifications……
So shrimp farmers, approach as another service to your business, not unlike micro-encapsulated shrimp larval feed or the implementation of IQF technology in shrimp processing.
It says mortality of over 50% on arrival…..sounds like bad handling to prawnmaster. Removing dead is standard practice. Confused with cull?
One does not cull shrimp – a fishy term.
If system is biosecure then no threat of this stress provoked problem reaching outside facility so no need to cull. Just continue growout. Standing at 12% survival currently.
With commercial logistics, systems, feed review.
Three things to note.
So much for biosecurity, OIE and buying from only approved US sources.
Prawnmaster has continuely argued that the US SPF program for vannamei is compromised. Vannamei is not even endemic to that country.
Secondly – why the word “cull”? If there is a risk to a local population then nothing less of total destruction with a zero discharge policy should be in place – but if that were case it would show biosecurity lapse in system. A cull of shrimp in a system is removing dead ones. So with over 50% dying on arrival not really a cull more a clean up is my guess.
Sounds like they need some Prawnmaster advice….
Proper handling and correct feed should do it….and, buying vannamei seed from Europe in future or use 12% survivors as base line for breeding?
Everyone says it was disease but actually…….
The Thai government took away the guaranteed minimum price support to shrimp farmers – they had already got into trouble with rice – which featured heavily in Thai politics. This included the Thai government cold-store backstop shrimp strategy.
The Thai government took away the rebate on every reefer container exported. Initially this was to promote exports and investments into shrimp industry.
Shrimp farmers held back on stocking. Shrimp processors and exporters (whom didn’t really get involved in farming), with forward contracts to fill, started looking at importing and/or offshoring into other countries (SE Asia).
In country shrimp experts played the disease card – with vibrio convenient.
It was highlighted earlier on in 2010 to the Thai export industry in GOAL Kuala Lumpur, that Thai shrimp farmers had gained market share by playing a strategy of using unsustainable and non-certified local fishmeal. Things got worse later when news media delved in further and found slave trade involved. Then the chemicals and mangroves….
So since then economics seems to have hampered the Thai regrowth of shrimp farming –
BUT hope is that new technology has helped basically to reformat the strategy with RAS (albeit still exclusion rather than containment) systems being used.
Flag and discover a disease then wait – to look as to how to profit.
Potentially same procedure for previously undetectable diseases.
Shrimp diseases are not a problem for the global shrimp industry. For shrimp farmers diseases are a worry though – one on a list of many.
How so? Well shrimp prices are at all time lows, indicative of good supply. If disease were a problem and affecting all geographical locations where commodity vannamei shrimp are grown then prices would start rising.
Commodity farmed vannamei shrimp has a global farming spread, a 3-5 month grow out cycle with a complete generational life cycle every 12 months. This together with the possibility to cold store frozen harvested stocks for up to 24 months gives the industry flexibility and rapid responsiveness to any potential disease outbreaks.
Of course if there is a global disease breakout prices will rise to such a degree that people will turn to eating chicken.
Prawn disease syndrome (PDS) is a objective view that promotes the rhetoric from many that the biggest problem for the industry is diseases. Not so! The biggest problem in the future is growing the market and concern that prices are so low for shrimp farmers.
These low prices turn people away from shrimp farming or, in a worst case scenario, be used to lower quality and hence costs in husbandry, be it feed, seed or management, which in turn could make shrimp more susceptible to local diseases.
Those in shrimp farming and reporting on shrimp farming should look to talk up shrimp farming and not catch a dose of PDS.
A win for seafood does not come off the back of the missfortunes of others.
The shrimp aquaculture industry does not support statements made like this one in Intrafish yesterday.
Reading the Rabobank report there is no mention at all of other proteins ‘winning’ out on this. They say clearly losses from ASF to lift “all protein boats”.
We, and the hundreds of thousands of shrimp farmers on the planet, would like to express our condolences and support to fellow farmers for what is currently happening with ASF.
Our shrimp industry has passed through three similar viral episodes over past three decades.
Intrafish journalists – please be a bit more professional on reporting sensitive issues and while we understand your close ties to a consolidated, concentrated (under investigation for price fixing) salmon fish sector, the seafood sector and farming sector has a far larger remit.
Can’t wait to see shrimp viruses and processes looked at using this technology.
Slices and slide using X-ray crystallography will become redundant older technology.
