             abstract = "Fisheries and aquaculture are important sources of food for 
                         hundreds of millions of people around the world. World fish 
                         production is projected to increase by 15% in the next 10 years, 
                         reaching around 200 million tonnes per year. The main driver of 
                         this increase will be based on fish farming management in 
                         developing countries. In Brazil, fish farming is increasing due to 
                         the climate conditions and large supply of water resources, with 
                         the production system based on Nile tilapia (Oreochromis 
                         niloticus) farming in reservoirs. Inland waters like reservoirs 
                         are a natural source of methane (CH4) to the atmosphere. However, 
                         knowledge of the impact from intensive fish production in net 
                         cages on CH4 fluxes is not well known. This paper presents in situ 
                         measurements of CH4 fluxes and dissolved CH4 (DM) in the Furnas 
                         Hydroelectric Reservoir in order to evaluate the impact of fish 
                         farming on methane emissions. Measurements were taken in a control 
                         area without fish production and three areas with fish farming. 
                         The overall mean of diffusive methane flux (DMF) (5.9 ± 4.5 mg CH4 
                         m\−2 day\−1) was significantly lower when compared 
                         to the overall mean of bubble methane flux (BMF) (552.9 ± 1003.9 
                         mg CH4 m\−2 day\−1). The DMF and DM were 
                         significantly higher in the two areas with fish farming, whereas 
                         the BMF was not significantly different. The DMF and DM were 
                         correlated to depth and chlorophyll-a. However, the low production 
                         of BMF did not allow the comparison with the limnological 
                         parameters measured. This case study shows that CH4 emissions are 
                         influenced more by reservoir characteristics than fish production. 
                         Further investigation is necessary to assess the impact of fish 
                         farming on the greenhouse gas emissions.",
