BIOFLOC Project
At the Research, Advisory and Capacity building Facility on New Adaptation Technologies (RAC/NAT), the aim is to facilitate the identification and evaluation of agricultural technologies in the form of inputs or practices that enhance productivity and resilience in specific agro-ecological zones, farming systems in the Region as well as aquaculture practices.
While there is a myriad of technologies available that have the potential to be efficacious, it is difficult to vouch for the adaptability in microclimates with varying characteristics. As such, RAC/NAT trials would serve as a model for testing the effect of technologies and ultimately aid the sector in making an informed decision with real-time regional data.
The facility is currently undertaking two research trials:
- Moruga Hot Pepper Trial
- Biofloc Aquaculture Shrimp Farming
Biofloc Aquaculture Shrimp Farming
RAC/NAT choose the Biofloc technology to explore shrimp farming as it is a sustainable aquaculture technique that involves the cultivation of beneficial microorganisms to maintain water quality in aquaculture systems. The Biofloc technology has the potential to enhance aquaculture productivity by providing a controlled environment that supports optimal growth conditions for the cultured species. Biofloc technology compared to the traditional aquaculture systems, is often considered more environmentally sustainable due to reduced water usage and effluent discharge, as well as lower reliance on external feed inputs.
Biofloc refers to dense colonies of microorganisms, such as bacteria, algae, and protozoa, that aggregate in the water column or on surfaces within the aquaculture system. These microorganisms help to recycle nutrients, particularly nitrogenous compounds like ammonia and nitrate, which are excreted by the aquatic animals (such as fish or shrimp) being farmed. They convert harmful ammonia into less toxic forms like nitrate, which can be utilized by the organisms in the system.
Once a high density of these microbial aggregates are maintained the biofloc system can effectively manage water quality parameters such as dissolved oxygen, pH, and suspended solids. This reduces the need for water exchange and minimizes the discharge of effluents into the environment.
