Overnight Larvae Wipeout: How a Southern Hatchery Recovered with the AIROFOG U260

Airborne and surface pathogens are the silent enemy of aquatic seedstock, here is how to shut them out

The night the tank water changed colour

Narumon runs a white-shrimp hatchery on the Songkhla coast, raising tiny larvae strong enough for farmers to stock. One morning, after a routine water change, two nursery tanks were full of dead larvae, and within a day it spread to several more.

Tests pointed to an infection spreading via water aerosols, equipment and cross-tank handling. In a warm, humid hatchery, bacteria and viruses ride the air mist and cling to walls, pipes and tanks, and fragile larvae collapse fast. Narumon knew that without controlling hatchery pathogens, customers would vanish.

Seedstock is the heart, when it is infected, everything fails

Output: dead larvae are a lost batch, and farmers who buy infected seed suffer downstream.

Finance: broodstock, feed, water and aeration costs are wasted, with a full system disinfection before the next run.

Reputation: in aquaculture, news of infected seed travels fast and can erase years of trust in one batch.

Why scrubbing tanks and wiping gear is not enough

Scrubbing only treats reachable surfaces, but hatchery pathogens ride aerosols from aeration systems and cling to ceilings, pipes, air lines and tank crevices. Point-by-point disinfection is slow and easy to miss. Hatcheries need whole-room disinfection covering air and every surface at once, without disturbing delicate systems.

The modern hatchery answer: the AIROFOG U260

Narumon rebuilt sanitation around the AIROFOG U260, fogging the whole room during tank rest, before each run, and on a cycle across floors, walls, equipment and air. Its 15-30 micron mist coats every surface including ceilings and pipes, breaking cross-tank transmission. At just 3.4 kg one person can fog the whole building; six nozzle settings tune the mist, and the 50 cm trunk hose reaches tank crevices and under shelving. Survival rates rebounded and customers returned.

10 reasons aquatic hatcheries choose the AIROFOG U260

Why professional hatcheries choose the AIROFOG U260:

1. 15-30 micron mist: coats air, ceilings, pipes and tank crevices, breaking aerosol transmission.
2. Whole-room in one pass: far better than slow point-by-point wiping.
3. Disinfectant flexibility: use aquaculture-safe solutions per expert advice.
4. Light 3.4 kg: one person fogs the whole hatchery without fatigue.
5. 6 nozzle settings: tune mist for equipment or whole-room work.
6. 50 cm trunk hose: reaches tank crevices, shelving and air lines.
7. Over 99.99% reduction: covers viruses, bacteria and fungi threatening seedstock.
8. Easy rest-period fogging: prepares clean rooms before each new run.
9. World-class standards: WHO, TUV Rheinland and Thai certification.
10. Fast payback: preventing one nursery collapse covers the machine.

What real users say

Since we fog the whole room with the U260 before every batch, survival is visibly better and we no longer lose entire tanks. Customers trust us again.
