Multi-strain synergy
Bacillus, Lactobacillus, nitrifying and photosynthetic bacteria work together in the water and in the animal's gut — a two-way mode of action.
A multi-strain aquaculture probiotic product blends Bacillus, Lactobacillus, nitrifying and photosynthetic bacteria to work in two directions at once: in the water they digest sludge and keep ammonia and nitrite low, and top-dressed onto feed they improve digestion, FCR and disease resistance. Standard in biofloc tilapia and vannamei shrimp culture.

System composition
Bacillus, Lactobacillus, nitrifying and photosynthetic bacteria work together in the water and in the animal's gut — a two-way mode of action.
Accelerates the nitrogen cycle, breaks down uneaten feed, faeces and bottom sludge, and stabilises pH and water colour — less water exchange needed.
Competitive exclusion of Vibrio and other pathogens reduces disease pressure and the need for antibiotics.
Top-dressed onto feed, the same strains improve digestion, feed conversion ratio and immunity.
Probiotics are now standard practice in biofloc tilapia and vannamei shrimp culture — water and gut duty in one product.
Powder or liquid, farm-scale packing, strain blend and CFU tunable to fish, shrimp or hatchery duty — OEM available.

FAQ
Aquaculture probiotics — the basis of probiotic fish farming — are concentrated live beneficial bacteria that work two ways: in the water they break down uneaten feed, faeces and sludge and keep ammonia and nitrite low, and in the animal's gut they improve digestion, feed conversion and disease resistance. This dual water-and-gut mode is why probiotic use in aquaculture and probiotics for fish farming have become standard practice.
The main types of probiotics in aquaculture used here are a multi-strain blend — commonly Bacillus subtilis, B. licheniformis, Lactobacillus, plus nitrifying and photosynthetic bacteria for water probiotics in aquaculture duty — with the blend and CFU count tunable to fish, shrimp or hatchery use. The same water-conditioning strains are also used to pre-treat pond-bottom soil before stocking (soil probiotics in aquaculture).
Yes — the consortium competitively excludes Vibrio and other pathogens, reducing the need for antibiotics, which is why probiotics are now standard in biofloc tilapia and shrimp culture.
They are produced as a powder or liquid in farm-scale pails and drums, for freshwater and brackish water.
The best probiotic for fish farming depends on the culture system. For open ponds and lined tanks, a water-conditioning type with Bacillus and photosynthetic bacteria controls ammonia and sludge build-up. For gut health — improving FCR and disease resistance — a feed-grade type with Lactobacillus top-dressed onto feed is more effective. The best probiotics for aquaculture combine both modes, which is why SIGMA's standard multi-strain blend covers water and gut duty in one product. A probiotic for fish pond should be applied at stocking and throughout the grow-out cycle.
Probiotics used in biofloc are standard practice — they accelerate establishment of a healthy microbial community in the floc, suppress Vibrio and pathogens, and stabilise ammonia and nitrite during the critical first weeks. Probiotic for biofloc application targets water-conditioning strains (Bacillus, nitrifying bacteria) dosed directly to the tank at start-up and then weekly. Gut probiotics for aquaculture are applied separately by top-dressing the feed. Together they are the most cost-effective input in a biofloc tilapia or shrimp system.
Yes — probiotics for prawn farming and vannamei shrimp culture are a core application. The water-conditioning blend suppresses Vibrio harveyi and parahaemolyticus — the leading disease agents in shrimp ponds — while the gut-health type improves shrimp FCR and survival. Aquaculture probiotic products for shrimp are supplied as powder in 1 / 5 / 25 kg bags for farm-scale dosing in both pond and biofloc systems.
