New Scientific Paper Shows Seafood Consumption Critical for Brain Development • Seafood Nutrition Partnership

Makes sense but is the effect compounded over generation one wonders?

More reasons to keep eating shrimp.


Rough start for UK land-based shrimp farm as virus forces cull….sounds more like stress inducing husbandry, handling and logistics followed by clean up……

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?

Natural Shrimp USA with viral disease using US vannamei….

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…

Trillions or is it quadrillions of shrimp….market price ( not disease! ) is producers worry.

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. 

Those pesky shrimp exclusion tactics for getting bio-security grading.

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.

Do shrimp, like fish, have slime….and anyone in the shrimp industry resarching?

Yes of course healthy shrimp are nice and slippery with a mucous type covering but anyone in shrimp industry researching same as here?

Anti-evolvability drug to combat AMR in shrimp…

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
