Shrimp resistance & Vibrio load in the gut
Why “Vibrio present” does not always mean disease — and what a farm should do to keep shrimp healthy and finish the crop. An 18-page technical monograph.

Striped catfish from nursery to grow-out: probiotics, digestive enzymes and feed protein and fat in new research
A trial published on 30 October 2026: adding 2 g/kg probiotic to feed containing a digestive enzyme cut FCR in 10 g catfish fingerlings from 1.60 to 1.33 over 90 days; higher doses did no better. In grow-out, 28% protein feed beat 32% on FCR, while 8% fat built up belly fat. Plus two trials on survival.
Research & trialsPreventing white feces from the gut: two new trials feeding beneficial bacteria and metabolites taken from healthy shrimp
A Ningbo University (China) team looked for what healthy shrimp guts have and white-feces guts lack, then fed it back for 14 days before challenge. Four beneficial strains cut deaths from 30.4% to 5.2% (2024); pyruvic acid and glutamine cut them from 45.2% to 12.7% (2026). Results from 50-litre tanks with a Vibrio challenge; no pond trial yet.

Binding and neutralising the Vibrio toxins behind EMS and TPD: clay, antibodies in feed and anti-virulence compounds — how strong is the evidence?
A review of 2019–2026 research: montmorillonite clay at 2.5–5 g/kg feed raised whiteleg shrimp survival to 83–94% versus 40% after an AHPND challenge; antibodies in feed protected shrimp in lab tanks; for TPD there are only small-flask anti-virulence trials. All were used before infection, and there is no pond dose yet.

El Niño 2026–2027: How Much Mineral Is Enough? (Part 5)
After rain, Mg, K or alkalinity reads below the table: how much is enough? The 1 mg/L × 1,000 m³ = 1 kg rule, what shrimp actually need according to published trials, and a worked 3,600 m³ pond example that needs only about 36 kg of KCl and 61 kg of sodium bicarbonate for the first step.

Shrimp sounds and AI in precision feeding management
Underwater acoustic sensors can add data on feeding activity that helps farmers adjust their automatic feeders. The technology’s value still has to be verified in the pond, through feed use, growth and environmental conditions.

Shrimp Reaches 69/kg in Just 54 Days — A Real Pond Case Study on Feed Control and 25% Water Exchange Reduction
A shrimp pond applying Than Vuong's environmental management and nutrition protocol achieved remarkable results: shrimp reached a size of 69 pieces per kilogram at 54 days of culture, with an FCR of 1.0 and a 25% reduction in water exchange compared to conventional methods. This article breaks down the complete protocol and the product combination behind these outcomes.
Research & trialsShrimp feed management in outdoor ponds for whiteleg shrimp
Feed is the highest variable cost in shrimp production, and feed management has a greater impact on the feed conversion ratio (FCR) at harvest than even feed quality.
Practical guidance
Organic copper promotes copper accumulation and transport, enhancing cold tolerance and physiological health of Pacific white shrimp
Organic copper (SO, O2, O3 and O4) enhances immune response (evidenced by a higher total hemocyte count, higher activity of acid phosphatase, alkaline phosphatase, phenoloxidase, hemocyanin, and lysozyme in the hemolymph, and higher gene expression of alkaline phosphatase, lysozyme, and hemocyanin in the hepatopancreas).

Cobia stocking fry selection and feeding techniques
Besides the advantage of rapid growth, cobia also possesses high adaptability and good disease resistance, making it quite commonly farmed in many coastal provinces of our country. Among these, farming in HDPE cages stands out for its high efficiency.
