Blows a hole through the US SPF program….
Of interest is mode of entry of virus or is it omni-present just never expressed to detectable levels…..
….would have thought once ‘erradicated’ in system then exclusion and biosecurity works.
Gonna be interesting…
One of the few industries where trillions of animals have been raised and managed.
Compare one 6 kilo salmon every three years. For that weight and in that time one is managing a thousand 20g shrimp. The numbers coming out of shrimp hatcheries globally are in the billions and have been for many decades.
With a 12 month turn over on life cycle (to gather resistance and to shake off any diseases), a geographic global farming spread, different seasonality and the possibility to shore up supply chain with a finished product freezing capability of up to 24 months, there is an easy bounce back from any diseases.
Which is why prices stay more or less within a fixed band. With the ability to buy same product from many different localities there is a great flexibility of offer to the demand in markets. This can mean playing producers off each other to get best deal and results in commodity low prices.
Genetic focus in hatcheries started for vannamei started with survival rates – a necessary competitive step when trying to compete with the economics of wild high performing seed. It was also because hatcheries were initially paid bonuses on numbers coming out not on quality of larvae.
This is why the stress test on shrimp coming out of hatcheries was developed.
However, and in reality, it has always been a numbers game. This same numbers game can overcome the survival quest and growth performance of shrimp is really the main requirement from farmers.
So all this talk about shrimp disease from people trying to get either into the industry or tout their positioning, is bullshit in the bigger picture. The main worry is low commodity prices globally and lack of downstream support by importers and distributors to promote farmed shrimp into the markets.
The genetics and 4.0 guys need to stop playing the disease card and look at shrimp growth and adaptation to alternative protein conversion capabilities.
Shrimp hatcheries since the 1980’s ran on positive pressure. Incoming aeration from external source for all culture tanks filtered.
Interestingly preventative systems keep coming up.
Yes of course healthy shrimp are nice and slippery with a mucous type covering but anyone in shrimp industry researching same as here?
…proof-of-concept for small-molecule inhibitors that could be administered with antibiotics to reduce resistance evolution by impeding differentiation of (bacterial) gamblers, without harming antibiotic activity….
Oh yes – here, put that in your pipe and smoke it…
But shrimp/prawn industry can lead the food industry and support public health programs by promoting that our offerings in the prawn sector have shrimply the best food safety and defense guidance…..
“Wash hands after handling and cook raw shrimp fully before eating”.
Agree totally with ACPF submission on their review of
‘Environmental Assessment Report – Import of Specific Pathogen Free Penaeus Monodon Into Australia’
Specifically that the importation of live P. monodon from countries with past disease outbreaks is seen as a risky venture.
The QSIA report “the List of Specimens taken to be Suitable for Live Import (Live Import List) in the Australia Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) to include specific pathogen free (SPF) black tiger prawns Penaeus monodon for the purposes of prawn aquaculture development.”
The proposal specifically intends to:
- import live Penaeus monodon broodstock from certified disease free hatcheries in Thailand or Hawaii into an Australian quarantine facility (never to leave the facility).
- the next generation be moved, after testing, to hatcheries and/or farms for grow out as commercial stock.
Seen from a bio-security angle this is the type of thinking from within the industry.
Agree totally with also with ACPF needing some sort of confidence building about bio-security.
The above does not go far enough….the two points require commenting on:
- if Australian quarantine facility why the need for certified free? Is that for some sort of genetic advantage?
- next generation better never to leave a quarantined, bio-secure facility until harvested and preferably value added (cooked). Containment over exclusion and limitation.
So can a new proposal be made based around RAS technology – which is also more land and environment friendly, that can also be true organic, even bio-diverse, urban and technologically advanced:
“the List of Specimens taken to be Suitable for Live Import (Live Import List) in the Australia Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) to include black tiger prawns Penaeus monodon for the purposes of prawn aquaculture development. The proposal specifically intends to:
- import live Penaeus monodon broodstock from any source into an Australian quarantine facility (never to leave the facility); and
- the next generation be kept in a quarantine facility (never to leave the facility) for grow out as commercial stock.
- commercial stock for human consumption will be harvested and sterilized to a value added offering prior to leaving chain-of-custody facility”
