The study of recirculating aquaculture system in pond and its purification effect

Comparison of bacterial communities in channel catfish Ictalurus punctatus culture ponds of an industrial ecological purification recirculating aquaculture system

“…Our results showed that the industrial ecological purification recirculating aquaculture system efficiently reduced the nitrogen and phosphorus contents after normal feeding for 2 months. Industrial eco-aquaculture pond systems have been reported to improve the water quality and provide good culture environments for fish (Liu, Xu, Wang, Wu, & Bao, 2014;Qu et al, 2017;Zhang, Li, Cheng, Xu, & Chen, 2016).…”

“…However, pond aquaculture also has adverse effects on the environment (Li et al, 2011), being a cause of water eutrophication in China and worldwide (Lemonnier, Hochard, Nakagawa, Courties, & Rodier, 2017). In contrast, pond industrial eco-aquaculture systems recycle and reuse the aquaculture water, reducing the negative effects on the ecological environment (Qu, Zhang, Jia, Liu, & Yang, 2017).The industrial recirculating aquaculture system was developed to improve the efficiency and sustainability of intensive aquaculture…”
