“…This result was consistent with the point of view that nontraditional biomanipulation had the possibility to influence some water quality parameters [39–41]. However, weakly relationship between the treatment type and variation of DO and PB concentrations also was observed in Table 3, which indicated that it was not effective for controlling PB concentration by using the silver carp, bighead carp or/and catfish in this study area.…”

The effects of stocking both filter-feeding fish and piscivorous fish were compared to the effects of stocking only filter-feeding fish for suppressing algal blooms and improving water quality in the impoundment area of Xiaojiang River where catfish were dominant. Using only filter-feeding fish for algal suppression and water quality control was more effective in the short-term, but use of both filter-feeding fish and piscivorous fish was better in the long-term. Obvious suppression of phytoplankton biomass (PB) only occurred during the first 14 days regardless of the fish stocked. Adding fish to the enclosure clearly alters phytoplankton community structure and introducing piscivorous fish to an enclosure stocked with filter-feeding fish changed the relative densities of dominant algae species. While stocking filter-feeding fish decreased total nitrogen concentration by removing phytoplankton, it did not effectively decrease total phosphorus and Chlorophyll a concentrations. Introducing piscivorous fish to the enclosure weakened the relationship between nutrients and phytoplankton. Results indicate that stocking only filter-feeding fish to improve water quality and suppress phytoplankton in an impoundment area is insufficient and other technologies and means should be applied simultaneously.

“…Silver carp ( Hypophthalmichthys molitrix ) is one of the major economic fish feeding on plankton in China and essential for Chinese freshwater aquaculture industry. Silver carp is strongly resistant to MC and implicated in the biological control of algae (Yi et al, 2016 ). In aquatic animals, toxicity is initially induced by MC through the addition reaction of MC and GSH as catalyzed by the GST gene (Martins et al, 2017 ).…”

Next-generation sequencing was used to analyze the effects of toxic microcystin-LR (MC-LR) on silver carp (Hypophthalmichthys molitrix). Silver carps were intraperitoneally injected with MC-LR, and RNA-seq and miRNA-seq in the liver were analyzed at 0.25, 0.5, and 1 h. The expression of glutathione S-transferase (GST), which acts as a marker gene for MC-LR, was tested to determine the earliest time point at which GST transcription was initiated in the liver tissues of the MC-LR-treated silver carps. Hepatic RNA-seq/miRNA-seq analysis and data integration analysis were conducted with reference to the identified time point. Quantitative PCR (qPCR) was performed to detect the expression of the following genes at the three time points: heme oxygenase 1 (HO-1), interleukin-10 receptor 1 (IL-10R1), apolipoprotein A-I (apoA-I), and heme binding protein 2 (HBP2). Results showed that the liver GST expression was remarkably decreased at 0.25 h (P < 0.05). RNA-seq at this time point revealed that the liver tissue contained 97,505 unigenes, including 184 significantly different unigenes and 75 unknown genes. Gene Ontology (GO) term enrichment analysis suggested that 35 of the 145 enriched GO terms were significantly enriched and mainly related to the immune system regulation network. KEGG pathway enrichment analysis showed that 18 of the 189 pathways were significantly enriched, and the most significant was a ribosome pathway containing 77 differentially expressed genes. miRNA-seq analysis indicated that the longest miRNA had 22 nucleotides (nt), followed by 21 and 23 nt. A total of 286 known miRNAs, 332 known miRNA precursor sequences, and 438 new miRNAs were predicted. A total of 1,048,575 mRNA–miRNA interaction sites were obtained, and 21,252 and 21,241 target genes were respectively predicted in known and new miRNAs. qPCR revealed that HO-1, IL-10R1, apoA-I, and HBP2 were significantly differentially expressed and might play important roles in the toxicity and liver detoxification of MC-LR in fish. These results were consistent with those of high-throughput sequencing, thereby verifying the accuracy of our sequencing data. RNA-seq and miRNA-seq analyses of silver carp liver injected with MC-LR provided valuable and new insights into the toxic effects of MC-LR and the antitoxic mechanisms of MC-LR in fish.The RNA/miRNA data are available from the NCBI database Registration No. : SRP075165.

“…H. molitrix can also indirectly affect nutrient concentrations by controlling phytoplankton biomass. The effectiveness of filter-feeding fish at consuming phytoplankton biomass remains controversial (Zhang et al 2006, Zhao et al 2013, Guo et al 2015, Yi et al 2016. In the present study, chl a concentrations were highest in the treatments which stocked H. molitrix (PF, PMPF and PMF), which indicated that H. molitrix can improve the phytoplankton biomass.…”

Jackson et al. (2003) found that feeds contributed 90% of the nitrogen (N) input in shrimp ponds, with only 22% converted to body N, 14% remaining in the sediment and most of the remainder (57%) discharged into the environment. Water quality deteriorates as a result of the uneaten feed and feces from the cultured species, and discharged effluents are among the major causes of widespread disease outbreaks in shrimp species. Effluent from shrimp ponds has also been speculated to be the main source of coastal pollution (San sana yuth et al. 1996, Sun et al. 1997, Costanzo et al. 2004). Both of these issues are
