This farm had problems with reduced yields and deteriorating water quality. We suggested using AQUA-Cal+ standard protocol to improve water quality and in doing so destressing the shrimp and improving yield.

Introduction
This customer is involved in a marine shrimp hatchery and grow out farm. Years of discharge of toxic sludge to the waterways in this area has resulted in deterioration of water quality and degradation of the habitat. This has resulted in reduced productivity and susceptibility to disease.
AQUA-Cal+, making aquaculture more sustainable
AQUA-Cal+ has already begun to transform prawn and shrimp farming, as well as fin fish farming. It improves water condition, reduces stress on the animals and helps lead to increased harvest weight and survival rates, whilst protecting the environment.
Multiple benefits in a single solution:
Improved water quality
- AQUA-Cal+ works as a water and pond bottom conditioner; clarifying the water, controlling pH and releasing alkalinity as required to aid in the digestion of organic matter.
Less stress on prawn and shrimp
- With stabilised conditions in the pond, stress is reduced. When stress is reduced and water condition is improved, both fish and prawns become healthier and more productive.
Sludge volume reduced
- As AQUA-Cal+ neutralises the pond bottom sludge and accelerates its breakdown, pond bottom septicity is prevented. AQUA-Cal+ helps release organic material for the growth of phytoplankton (natural food for shrimp), while binding the toxic contaminants. Subsequently, the smell of the sludge is greatly reduced, with less toxic compounds in the water.
Iron suppression
- Conditioning with AQUA-Cal+ removes the iron by flocculation from the water, significantly reducing turbidity and toxicity. The stocking of the pond after the water is conditioned reduces the subsequent mortality of the post-larvae.
Higher revenue – yield at harvest up to 20%*
- Results from trials on both Pacific White Shrimp and Tiger Prawns show that AQUA-Cal+ has a superior performance to probiotics in controlling ammonia, nitrite and pond bottom sludge.
- The data consistently shows AQUA-Cal+ stabilises alkalinity; suppresses extreme changes in pH; provides ingestible essential magnesium and calcium; reduces turbidity, improves light penetration; improves phytoplankton productivity; reduc[1]es toxic metals in the system (copper and zinc); and reduces ammonia and nitrite.
“AQUA-Cal+ is a great alternative and a more sustainable approach to shrimp culture. Guided by our expertise and protocols, we help farmers reduce pollution while increasing their yield and revenue.
