AQUA-Cal improves the quality of water and thereby promoting better and healthy aquatic life at IKerpan Farm, Kerpan, Malaysia.

case study summary

Challenges
  • Presence of toxic sludge and the heavy metals causing water turbidity
  • Constant fluctuation in pH and alkalinity leading to poor water quality
  • Poor aquatic ecosystem affecting the health of the shrimp yield
  • Low quality of shrimps having a small size and low survival rate
Objective
  • Achieving a PL survival rate of 80% or above.
  • Reducing the toxic sludge build up at the bottom of the pond.
  • Reducing water turbidity and the presence of any heavy metals.
  • Reducing large fluctuation in pH.
  • Maintaining and preventing large fluctuation in alkalinity (80 – 160ppm).
  • Passing DOC 50 days.
  • Passing DOC 80 days (near harvest).
  • Achieving Higher Daily Growth (ADG), Higher Body Weight (ABW) at harvest and lower FCR against Control.

Benefits of AQUA-Cal

Reduces the sedimentation time, thus reduces the need for desludging

Reduces the presence of heavy metals and toxic chemicals

Controls fluctuation in pH and alkalinity

Increases water clarity

Promotes algae growth

Improves self- sustainability and maintains a healthy ecosystem

Improves shrimp growth and quality of the yield

Increases shrimp survival rate

Introduction

Calix’s Aqua-Cal+ is a special formulation of Magnesium Hydroxide enhanced with Calcium. It improves the quality of water and thereby promoting better and healthy aquatic life. Aqua-Cal+ is non-toxic, non-corrosive, safe to handle and environment-friendly.

A trial was taken at the shrimp pond, where a comparison was done between a Control Pond that followed standard practices as opposed to dosing of AQUA-Cal +1 and AQUA-Cal +2 in two other ponds. A comparison of the water quality and shrimp yield in all the three ponds was performed. The ponds treated with AQUA-Cal+ showed a significant improvement in water quality and generated a healthier shrimp yield.

PROGRESS GRAPH

Overall summary - 7 reasons for adopting AQUA-Cal:

1 – An effective, multi-functional, non-toxic product for the environment, humans, and aquatic life.

2 – Works great with minimal desludging/water exchange practices.

3 – Promotes stronger, faster shrimp growth and higher survival rate of above 90% by preventing toxic sludge build-up.

4 – Enables shorter sedimentation time and excellent heavy metal flocculation for cleaner and safer pond water.

5 – Helps to reduce FCR by promoting good algae growth.

6 – Helps to reduce or replace some synthetic chemicals.

7 – Helps to preserve the environment towards a sustainable and expandable business.

The application

AQUA-Cal+ is a special formulated high surface area Magnesium Hydroxide enhanced with Calcium designed for use in aquaculture ponds.
AQUA-Cal+ is a water conditioner and acts to improve the overall water quality while delivering a number of unique properties to protect and enhance shrimp culturing:
  • Reduces the water turbidity
  • Effectively binds the iron and other heavy metals to prevent metal toxic
  • Stabilizes water alkalinity
  • Recondition and stabilize the bottom pH
  • Reduces the hydrogen sulphide (H2S)
  • Neutralize the nitrites, phosphate and ammonia
  • Flocking and break down of organic matter in the system
  • Digests the sludge and create a clean pond bottom
AQUA-Cal+ is non-toxic, non-corrosive, safe, environmentally friendly and meets many core needs in aquaculture.

AQUA-Cal+ is made by flash calcining a mixture of magnesite and dolomite to produce a unique, very high surface area powder, and then hydrating the powder to produce a slurry for ease of application to ponds. It has been specially formulated to impact on both the aqueous and benthic ecosystems in the pond.
