Aquaculture Disease Diagnostics
Know what is in your seed before you stock the pond.
PCR-based screening for WSSV, EHP, AHPND, IHHNV and Vibrio — on post-larvae, broodstock, tissue and pond water. Run in our own Hyderabad molecular laboratory and interpreted by a research scientist, not returned as a bare number.
One infected batch of seed can cost an entire crop. A test costs a fraction of that.
What we screen for
The pathogens that actually decide your crop.
WSSV — White Spot Syndrome Virus
The single most destructive pathogen in Indian vannamei and monodon culture. Detected by real-time PCR on post-larvae, tissue or broodstock.
EHP — Enterocytozoon hepatopenaei
The cause of slow growth and stunted crops where mortality stays low but harvest weight collapses. Screened before stocking and during culture.
AHPND / EMS
Acute Hepatopancreatic Necrosis Disease — early mortality syndrome — detected by PCR targeting the toxin genes.
IHHNV
Infectious hypodermal and haematopoietic necrosis virus, associated with deformity and reduced growth performance.
Vibrio load & water screening
Microbiological assessment of pond and hatchery water, with identification of isolates by sequencing where required.
Custom panels
Multi-pathogen panels built around your hatchery protocol, species and the history of your site.
Who we work with
From hatchery to harvest.
Hatcheries
Routine broodstock and larval screening under a monitoring agreement, so every batch you sell is backed by data.
Farmers & farm groups
Pre-stocking seed screening and in-crop health checks when growth or behaviour changes.
Aqua feed & probiotic companies
Strain identity confirmation and product verification for the probiotics and biologicals you supply.
Integrators & processors
Supplier seed verification and pond-level surveillance across your grower network.
Why a scientist-read report matters
A positive result is not the end of the question.
A detection tells you a pathogen is present. It does not tell you whether the load justifies an emergency harvest, whether the source is the seed or the water, or whether your last treatment actually worked.
Those calls decide whether you save a crop or lose one — and at Manna Biotech they are made by working research scientists who will get on a call with you.

How it works
Fast, because timing decides everything
Aquaculture decisions cannot wait a week. Tell us your stocking or harvest date and we schedule around it.
Sampling guidance included
How many post-larvae, from where in the tank, how to pack and preserve — bad sampling ruins good testing, so we guide it up front.
Send from anywhere in AP or Telangana
Samples travel to our Nacharam laboratory by courier with the packing protocol we provide. No need to visit.
Monitoring agreements for hatcheries
An agreed panel and schedule, priority slots and a named scientist who knows your site history and your trend line.
What this service is — and is not.
These diagnostics support farm and hatchery management decisions. They are provided for research and advisory purposes and are not accredited statutory or export-certification tests. For export residue certification and statutory testing, consignments must go through the approved government-designated channels.
We report what we find, honestly. No laboratory can guarantee a disease-free crop, and we will never claim to.
Request testing
Tell us about your farm or hatchery.
Share your location, species, whether you need pre-stocking seed screening or an in-crop check, and your stocking or harvest date. We will confirm the right panel, sampling instructions, turnaround and cost.

Questions
Frequently asked questions
How do I test shrimp seed for white spot (WSSV) before stocking?
+
Send a representative sample of post-larvae before you stock. We screen by real-time PCR for WSSV and, if you wish, for EHP, AHPND and IHHNV in the same submission. Tell us your stocking date when you enquire and we schedule the run around it, because a result that arrives after stocking is of no use to you.
What is EHP and why does it matter if mortality is low?
+
EHP (Enterocytozoon hepatopenaei) is a microsporidian that causes slow growth and stunted crops rather than sudden death. Ponds can look healthy while harvest weight collapses, which is why EHP screening before stocking has become as important as WSSV screening.
How many post-larvae or how much tissue should I send?
+
It depends on the pathogen and the stage, so we give you the exact sampling instruction before dispatch — how many animals, from where in the tank, and how to pack and preserve them. Bad sampling ruins good testing, so we prefer to guide this up front rather than test an unrepresentative sample.
Can I send samples from Andhra Pradesh or elsewhere without visiting the lab?
+
Yes. Samples travel to our Nacharam, Hyderabad laboratory by courier using the packing protocol we provide. Farms and hatcheries across Andhra Pradesh and Telangana send samples this way; there is no need to visit in person.
Can these reports be used for export certification?
+
No. These diagnostics support farm and hatchery management decisions and are provided for research and advisory purposes. They are not accredited statutory or export-certification tests — export residue certification must go through the approved government-designated channels.
A pathogen was detected. What happens next?
+
A detection alone does not tell you whether to harvest early, whether the source is the seed or the water, or whether your last treatment worked. Our reports are interpreted by research scientists who will discuss the result with you, so you are making a management decision on evidence rather than on a bare positive or negative.
Do you offer regular testing arrangements for hatcheries?
+
Yes. Hatcheries and larger farms usually work on a monitoring agreement — an agreed panel and schedule, priority slots, and a named scientist who knows your site history and watches your trend line. It costs less per sample than ad-hoc testing.
