Improving Water Use Efficiency in Shrimp Cultivation Using a Biofloc System: C.P. Vietnam
Shrimp cultivation in Vietnam is generally practiced using an outdoor pond and phytoplankton, which relies on photosynthesis. This results in limitations due to pH levels, vast differences in the ability of oxygen to dissolve between mornings and afternoons, difficulties in controlling shrimp cultivation, and high amounts of built-up ammonia and nitrites.
To overcome these limitations, C.P. Vietnam developed a technology for shrimp farming, covering the process from juvenile shrimp hatching all the way to cultivation, that uses a greenhouse structure for shrimp cultivation instead of the traditional outdoor pond. This helps to protect against environmental contaminants, and enables C.P. Vietnam to regulate temperature changes and pH levels. C.P. Vietnam has also integrated Biofloc technology into its shrimp nurseries and cultivation process.
Following improvements to its shrimp cultivation using a Biofloc system for nursing juvenile shrimp and growing them into adults, C.P. Vietnam was able to increase its output up to 15 tons per rai per year, and reduce water use from 74,250 cubic meters to merely 26,850 cubic meters – a 64% reduction.
