“…In the present study, we found that several bacterial phyla, such as Proteobacteria , Actinobacteria , Bacteroidetes , and Firmicutes , were dominant in both gut and water microbiomes of two breeding models. These findings are similar to previous findings in microbiomes of rearing water and guts of other crustaceans ( 16 – 20 ). Compared to the CM model, the diversity and community structure of both gut and water microbiomes were significantly different in the RC model, suggesting that the breeding model may affect the microbiome assembly of crayfish gut and water.…”

“…So far, only limited studies have focused on the microbiome in the RC model. The 16S rRNA high-throughput sequencing approach has been used to assess the composition and diversity of bacterial communities in crayfish gut, water, or sediment in the RC model ( 16 – 20 ). Two previous studies have suggested that there was no significant difference in gut, water, and sediment microbiomes between the RC and crayfish monoculture (CM) models ( 18 , 19 ).…”

“…Two previous studies have suggested that there was no significant difference in gut, water, and sediment microbiomes between the RC and crayfish monoculture (CM) models ( 18 , 19 ). Zhang et al suggested that overutilizing the RC model can lead to the destruction of soil microbial ecology ( 20 ). However, the effect of the breeding model on microbiome assembly and composition and the association of the microbiome with water quality and crayfish growth remain largely unknown.…”

“…Food shortage has become an urgent problem to be solved because of the rapid growth of population and limited water and soil resources (Bashir et al, 2020;Xu et al, 2021;Zhang et al, 2021). As one of the important staple foods, rice (Oryza sativa L.) feeds roughly half of the global population (Fageria, 2007;Liu et al, 2018).…”

“…The co-culture of rice and aquatic animals has a history of more than 2,000 years in China (Wang et al, 2021). It has been considered a strategy to improve the utilization of land and water resources in paddy fields to provide both grains and aquatic animal protein products to humans (Zhang et al, 2021). The Chinese mitten crab (Eriocheir sinensis) is native to the coastal rivers and estuaries of the Yellow Sea.…”

Rice–crab co-culture is a high-benefit eco-breeding pattern that has been extensively developed in many regions of China. However, little attention has been paid to the safety of pesticides used to control rice pests in the crab–rice co-culture system. This study monitored the actual residue levels of propiconazole in water and soil of rice–crab co-culture fields and evaluated the acute toxicity, subchronic toxicity, and bioaccumulation of propiconazole to Eriocheir sinensis. We observed that the residue level of propiconazole in paddy soil was higher than that in paddy water within 42-day field monitoring. Propiconazole demonstrated a low acute toxicity (96 h-LC50 > 100 mg/L) to E. sinensis and exhibited no obvious adverse impact on the growth of E. sinensis after exposure to 500 μg/L, which was 10 times the actual residual concentration of propiconazole in the crab–rice co-culture field. The highest bioaccumulation of propiconazole was obtained from gills, followed by the hepatopancreas and meat. These results will contribute to the guidance of scientific utilization of pesticides in the crab–rice co-culture field.

BACKGROUND: Cyantraniliprole, a second-generation diamide insecticide, was recently introduced in China, where the rice-crayfish integrated system (RCIS) is practiced to control rice pest infestations. The aim of this study was to investigate the residue behavior of cyantraniliprole in RCIS and its potential ecological effects on nontarget Procambarus clarkii in order to recommend safe pesticide application strategies.RESULTS: Cyantraniliprole dissipated in rice plants according to first-order kinetics, with an average half-life of 5.25 days and a dissipation rate of >95% over 28 days. The terminal cyantraniliprole residue levels in rice straw, paddy hull and brown rice were all within 0.2 mg kg −1 , which is the China-recommended maximum residue limit. The tissues of P. clarkii accumulated and distributed cyantraniliprole in the descending order gill > hepatopancreas > intestine > muscles. Procambarus clarkii exposed to cyantraniliprole exhibited a moderate decrease in weight gain, specific growth rate and condition factor compared to the control group. Exposure of P. clarkii to cyantraniliprole caused histopathological alterations to the hepatopancreas, but the alterations were not statistically significant in the 60 g ai ha −1 cyantraniliprole group when compared with the control group.CONCLUSION: We suggest that 10% cyantraniliprole oil dispersion be sprayed twice at an interval of 14 days and dosage of 60 g ai ha −1 during the growth stage of rice in RCIS.
