Effects of temperature on nitrous oxide (N2O) emission from intensive aquaculture system

Impact of rice-fish/shrimp co-culture on the N2O emission and NH3 volatilization in intensive aquaculture ponds

“…The N 2 O flux rates of this study were far lower than that measured by using N 2 O-sensor (458.3-2358.3 μg m −2 h −1 ) (Z. Hu et al, 2013) and that estimated by model approaches (116.7 × 10 3 -191.7 × 10 3 μg m −2 h −1 ) (Paudel et al, 2015). The emission factor of N 2 O emission to total N input in feed was 0.18% for catfish pond in this study (Table 4), which was lower than that of crucian carps (0.46%) (Wu et al, 2018) and crabfish ponds (0.66%) (Liu et al, 2016).…”

The influence of solid retention time on IFAS-MBR systems: Assessment of nitrous oxide emission

“…Furthermore, since N 2 O represents an intermediate product of the heterotrophic denitrification process, it can be produced via incomplete heterotrophic denitrification (Liu et al, 2015). Therefore, both autotrophic and heterotrophic bacteria can be responsible for N 2 O production during BNR (Kampschreur et al, 2009;Chandran et al, 2011;Law et al, 2012;Paudel et al, 2015). Moreover, during phosphorus removal process, N 2 O production can also occur (Kampschreur et al, 2009;Zhou et al, 2012).…”

Desempenho de juvenis de tambatingas em diferentes sistemas de cultivo

“…Ao avaliar os resultados dos indicadores de qualidade de água observa-se que em relação a temperatura, o sistema de recirculação apresentou média superior aos demais tratamentos, com diferença significativa. Paudel et al (2015) explicam que a temperatura possui um importante papel no desempenho dos cultivos aquícolas, influenciando diretamente no metabolismo dos peixes e na taxa de conversão alimentar; e indiretamente no metabolismo ambiental influenciando a atividade microbiana, principalmente em locais onde ocorrem variações sazonais deste fator.…”
