“…Li, Dong, Gao, and Zhu () reported that compared with the culture mode of A. japonicas only, the organisms’ utilization rate of organic carbon, nitrogen and phosphorus in the sea cucumber‐jellyfish‐prawn mode was up to 18.90%, 21.90% and 38.00% higher, respectively, indicating that polyculture contributed to the organisms’ utilization rate of nutrients. Zhang et al () found that in the Channa arguss ‐dominant system with Hypothalmichthys nobilis added, when the stocking density of H. nobilis was 0.15 ind/m 2 , the N utilization rate was significantly higher than that in the culture group of single fish species. These results all show that optimizing and managing the species and stocking density of polycultured organisms can improve the conversion efficiency of nutrients in water, improve the structure and function of the aquaculture ecosystem, and increase aquaculture production.…”

The viability of placing abalones (Haliotis discus hannai), sea cucumbers (Apostichopus japonicas) and rockfish (Sebastes schlegeli) in a polyculture system, the effect of this mixed species group on the system's nitrogen (N) and phosphorous (P) budgets, and the growth and food intake of the organisms in the system were examined using a recirculating aquaculture system. Four replicates were set up for each of three treatment groups (abalone only (C), abalone-sea cucumber (AS) and abalone-sea cucumber-rockfish (ASF)) with an experimental period of 60 d. Compared with the C group, in the AS group the abalone survival rate and specific growth rate (SGR) of body weight increased and the harvested abalones from the polyculture system became the main source of N and P output of the polyculture system. However, the N and P output in the water layer did not differ significantly from that in the C group (p > 0.05), and the N utilization rate was significantly higher than that in the C and ASF groups (p < 0.05). Compared with the AS group, in the ASF treatment the SGR of body weight as well as the protease and amylase activities of sea cucumbers were significantly higher (p < 0.05), the water layer and faeces became the main sources of N and P output in the system. These results showed that the AS polyculture mode significantly improved the N and P utilization rates in the system and led to increased aquaculture production.

“…Due to the suitable climatic conditions and organic matter from intricate rivers, the coastal area of Dandong provides a unique opportunity to develop coastal aquaculture. Polyculture, two or more cultural species in the same pond, is a main mode of aquaculture in Dandong because of its environmental friendliness and circular utilization of nutrition (Zhang et al, ). Polyculture with Chinese shrimp Penaeus chinensis , jellyfish Rhopilema esculenta and razor clam Sinonovacula constricta (S.J.R) is one of the most common aquaculture systems in Dandong.…”

Polyculture with Chinese shrimp Penaeus chinensis, jellyfish Rhopilema esculenta and razor clam Sinonovacula constricta (S.J.R) is a common aquaculture system in Dandong, China. Investigation on the composition and function of microbial communities and their relationship with environmental factors in aquaculture systems have crucial implications. Therefore, the sequencing of 16S rRNA gene was applied to profile the bacterial community composition of water and sediment in S.J.R polyculture system in the present study. Proteobacteria was the dominant phylum in S.J.R polyculture ponds following with Actinobacteria and Bacteroidetes in water; in contrast, more diverse phyla were detected in sediments. Water temperature, pH and dissolved oxygen were determined the bacterial community composition in the S.J.R polyculture systems. Specially, Planktomarina, PS1 clade, Candidatus Aquiluna and Fibrobacteres, which can resist the phytoplankton blooms or degrade the cellulose, were more abundant in water at the early stage of cultivation in the S.J.R polyculture system. Moreover, the functions of bacterial communities in water were mainly associated with cell communication mediated, while the functions related to basal metabolism were enriched in sediments. The findings of this study allowed us to better understand the bacterial community in the S.J.R polyculture system and accumulated data for the improvement of cultural management.

“…In an aquaculture system, the nutrient inputs comprise the inflow water, fertilizers, feed and aquatic animals, and the outputs comprise the outflow water, harvested animals and sediment accumulation (Briggs & Funge‐Smith, ; Casillas‐Hernández, Magallón‐Barajas, Portillo‐Clarck, & Páez‐Osuna, ). In most studies, fertilizers and feed have been found to represent the largest nutrient sources (Acosta‐Nassar, Morell, & Corredor, ; Briggs & Funge‐Smith, ; Casillas‐Hernández et al, ; Mariscal‐Lagarda & Páez‐Osuna, ; Páez‐Osuna, Guerrero‐Galván, Ruiz‐Fernández, & Espinoza‐Angulo, ; Da Silva, Wasielesky, & Abreu, ; Zhang et al, ). However, in some studies, mud has been identified as the dominant source of nitrogen and phosphorus (Nhan, Verdegem, Milstein, & Verreth, ; Yi et al, ).…”

“…The nutrient inputs and recovered nutrients (determined from the WGs of the harvested P. fulvidraco and N. nucifera ) were used as indices of nutrient removal efficiency. Nutrient inputs, outputs and utilization efficiency in the harvested P. fulvidraco and N. nucifera were calculated as follows (Zhang et al, ): Nutrient content in fish/lotus/feed/fertilizer/mud/water = nutrient concentration in fish/lotus/feed/fertilizer/mud/water × total amount of fish/lotus/feed/fertilizer/mud/water E f = nutrient concentration in P. fulvidraco × total gained biomass of P. fulvidraco E l = final nutrient concentration in N. nucifera × total amount of harvested N. nucifera − initial nutrient content in N. nucifera × total amount of transplanted N. nucifera U E = ( E f + E l )/ E i × 100 where E f is the amount of nutrient in gained biomass of cultured fish; E l is the amount of nutrient in gained biomass of cultured lotus; and E i is the total nutrient input during the experiment. …”

An experiment was conducted to determine the growth efficiency of lotus (Nelumbo nucifera Gaertn) on nutrient capture in farming systems of yellow catfish (Pelteobagrus fulvidraco Richardson). Three treatments, a control treatment of N. nucifera alone (T1), a treatment of N. nucifera‐P. fulvidraco co‐culture (T2) and a treatment of P. fulvidraco alone (T3), were conducted in triplicate. Except pH, conductivity and chemical oxygen demand (CODMn), most of the water quality parameters were significantly lowered by N. nucifera cultivation. Total nitrogen and phosphorus concentrations in the T2 system were 62.2% and 71.6% higher than those in the T1 system respectively; and 31.8% and 59.2% lower than those in the T3 system respectively. The nitrogen and phosphorus release rates were 41.2% and 36.8% in the T2 system, respectively, and 95.6% and 99.1% in the T3 system respectively. 7.31%–21.4% of nitrogen and 3.35%–15.9% of phosphorus were unaccounted. N. nucifera can effectively remove nutrients from water and sediments and may promote the outflow of nutrients. No significant difference in fish or N. nucifera growth performance was observed among the systems. This study indicates that the co‐culture of N. nucifera with P. fulvidraco is an optimal culture system that can increase food production and reduce waste discharge.
