- Aquaculture is one of the most rapidly growing agriculture industries in the world. However, its rapid development could result in significant environmental concerns such as antimicrobial resistance, eutrophication and climate change. To this date, very few studies have been conducted to investigate the Green House Gas (GHG) emissions produced by aquaculture systems and their negative effect on the environment. The aim of this study was to create and propose a novel model capable of measuring the amount of direct GHG emissions produced by a modified recirculating aquaculture system (RAS) using an adapted respiration chamber design. In order to achieve this aim, two types of laboratory-scale Tilapia (Oreochromis sp.) aquaculture systems, soil-based and non-soil-based RAS, were used to identify and quantify the Methane (CH4) and Carbon dioxide (CO2) emissions. The results of the water parameters analysis indicated that there was no significant difference (P> 0.05) in the water temperature, dissolved oxygen concentration, pH and Nitrite (NO2) levels between treatments. The results of the gas analysis indicated that there was no significant difference (P>0.05) in CH4 and CO2 emissions between treatments. However, a significant effect (P< 0.001) of time on the emissions of CH4 during the gas analysis and measurement period was evidenced, suggesting an increased methanogenic activity in the anoxic areas of the sediment through time. The results of this study suggest that the proposed novel model is effectively capable of measuring CH4 and CO2 emissions produced in recirculating aquaculture systems and that its application and adaptation to larger aquaculture production systems should be evaluated.
