The Microbiome Structure of a Rice-Crayfish Integrated Breeding Model and Its Association with Crayfish Growth and Water Quality

Abstract

The present study comprehensively compared two different breeding models in terms of their microbiome composition and the associations of the microbiomes with crayfish growth and water quality. RC model-specific microbiome composition was identified; these microbes were found to have a positive association with water quality and crayfish growth.

Rice flowering improves the muscle nutrient, intestinal microbiota diversity, and liver metabolism profiles of tilapia (Oreochromis niloticus) in rice-fish symbiosis

“…Our study revealed that compared with the traditional tank-reared fish, the body weight and weight gain rate of tilapia in the paddy groups were obviously higher, especially during the period after rice flowering (i.e., bRT vs bTT), indicating that the rice-fish coculture and the fallen pollen after rice flowering may be helpful to improve the tilapia growth performance, which was similar with the results in rice-crab and rice-crayfish coculture systems [9,10]. Besides, the muscle TUAA proportion of tilapia in the paddy groups (aRT and bRT) was both higher than that in the tank groups at the same time, which was consistent with the findings in rice-fish [14] and rice-shrimp [15] coculture systems that the paddy model improves the overall fish umami than tank model.…”

“…Thus, tilapia is the ideal fish species for the symbiotic mode of rice and fish, which is also beneficial to control the weeds and insect pests in paddy fields. It has been reported that crab and crayfish in the corresponding rice-crab/rice-crayfish coculture model showed better growth performance and muscle quality than that of the monoculture system, with enhanced umami, sweetness, and overall flavor [9,10]. The rice-fish coculture model could improve the economic performance of aquatic animals [11,12].…”

Effect of Rice Straw and Stubble Burning on Soil Physicochemical Properties and Bacterial Communities in Central Thailand

“…Chloroflexi were the dominant bacteria in both preburning and postburning fields, followed by Actinobacteria, Firmicutes, Planctomycetes, Proteobacteria, and Acidobacteria, although no significant difference was detected among the sites ( Figure 4 a). Previous studies also reported the dominance of these bacterial phyla in paddy soils [ 65 , 66 , 67 , 68 ]. Chloroflexi act as primary degraders of polysaccharides under the anaerobic conditions of rice fields, whereas Actinobacteria can also degrade OM under such conditions [ 69 ] and produce enzymes involved in carbon cycling for plant residue decomposition and carbon sequestration in soils [ 70 ].…”

The nutritional and functional properties of 1-oleoyl-2-palmitoyl-3-linoleoylglycerol-rich oil: promoting early-life growth and intestinal health with alterations in the intestinal microbiota of Micropterus salmoides

“…Specifically, Streptomyces has beneficial effects on the growth and development of aquatic animals. 58,59 Meanwhile, studies have shown that Streptomyces, Saccharopolyspora_spinosa, and Nocardiopsis_kunsanensis could produce a variety of bioactive secondary metabolites to resist bacteria, viruses, and parasites, 60 and they seldom or never cause injuries to the beneficial species and humans. 61 The PPP and MO groups were rich in Staphylococcus_nepalensis, Romboutsia_ilealis, and Bacillus_sp01315538522 species (Fig.…”
