“…Genetic diversity was of great importance to the viability of populations (Qi et al, ) and widely accepted as an important component of population fitness (Napora‐Rutkowski et al, ). Nucleotide diversity was considered to be one of the major indicators of fish population genetic diversity because it represented the mean number of differences among all pairs of haplotypes (Wang et al, ).…”

“…Although hatcheries production could help the recovery of natural resource, the release of fish seedling into natural habitats is likely to reduce the genetic diversity of this species (Wang, et al, ). Genetic diversity is of great importance to the viability of populations (Qi, et al, ). To protect and sustainably exploit the natural resource, population genetic research (genetic structure, population divergence and genetic diversity) is needed to provide a guidance for resource conservation and management (Ortega‐Villaizán Romo, Suzuki, Nakajima, & Taniguchi, ).…”

Fish of genus Erythroculter (Cypriniformes, Cyprinidae, Abramidinae) are important commercial freshwater species in China. In this work, morphological characters and gene sequences of mitochondrial CO I and Cyt b were analysed to investigate the germplasm differences among E. mongolicus, E. dabryi and E. ilishaeformis. Results demonstrated that about countable trait, there were six traits (scale in/ above/ below lateral line, gill‐raker in first left gill‐arch and branched fin‐ray in anal/ pectoral fin) showed significant differences. Gene fragments of CO I and Cyt b was 905 bps and 1,142 bps respectively. In CO I, there were 54.3% base content of A + T, 14 haplotypes and 84 nucleotide variable sites. As to Cyt b, there were 56.3% base content of A + T, 20 haplotypes and 142 nucleotide variable sites. In both CO I and Cyt b, the highest and lowest nucleotide diversity was detected in E. ilishaeformis and E. mongolicus respectively. According to morphological distance, genetic distance, genetic differentiation coefficient (Fst) and gene flow, E. dabryi was grouped together with E. ilishaeformis firstly, and then clustered with E. mongolicus. These results might be useful in the conservation and management of fishery resources of these three species.

“…However, the natural population resources of this fish declined sharply due to the water‐pollution, overfishing and habitat destruction during the past decades (Hu, Zhou, Zhang, Zhao, Zhou, Xu, Shen & Huang ; Qi et al . ; Qi, Qin & Xie ). Furthermore, fish diseases caused by viruses, bacteria and parasites have long been recognized as a significant constraint on aquaculture production, which also occurred in the aquaculture of topmouth culter (Verschuere, Rombaut, Sorgeloos & Verstraete ; Liu, He, Li & Yang ; Bondad‐Reantaso ).…”

“…This fish has become as one of the most important cultural fish species in China owing to its economic, ecological and nutritional contribution in aquaculture (Wang, Chen, Yang, Hou, He, Gu & Liu 2007;Qi, Guo, Xie, Wu, Lu, Duan & Zhou 2013;Wang, Han, Chen, Zhao & Hao 2014). However, the natural population resources of this fish declined sharply due to the water-pollution, overfishing and habitat destruction during the past decades (Hu, Zhou, Zhang, Zhao, Zhou, Xu, Shen & Huang 2003;Qi et al 2013;Qi, Qin & Xie 2015). Furthermore, fish diseases caused by viruses, bacteria and parasites have long been recognized as a significant constraint on aquaculture production, which also occurred in the aquaculture of topmouth culter (Verschuere, Rombaut, Sorgeloos & Verstraete 2000;Liu, He, Li & Yang 2006;Bondad-Reantaso 2007).…”

An integrated and comprehensive transcriptome reveals immune‐related genes and signal pathways in topmouth culter ( C ulter alburnus )

Topmouth culter (Culter alburnus) is an important freshwater species in China. In recent years, the population of topmouth culter has declined sharply due to the increasing pollution, overfishing and habitat destruction. It may lead to adverse effects, including weakening health, causing disease, and reducing the quality of topmouth culter. It is urgent to conduct resource management, protection and genetic improvement strategies in topmouth culter, especially develop genetic breeding program with disease resistance. In this study, we applied RNA‐seq technology to de novo assemble a comprehensive transcriptome, and to discover immune‐related genes and pathways in topmouth culter. A total of 102 017 transcripts were assembled with an average length of 945 bp, of which 45 482 protein coding sequences were predicted. BLAST search resulted in 53 575 and 45 602 transcripts with homologous sequences in NCBI‐NR and UniProt respectively. Further functional analysis identified 24 052 transcripts in Gene Ontology (GO) categories and 19 260 transcripts in KEGG pathways. Significantly, 13 immune‐related pathways with 524 immune‐related genes were identified. Our data provided an integrated and comprehensive transcriptome resource for topmouth culter, which could be essential for further research in selective breeding of disease resistance, functional genomics, and genome editing of topmouth culter.
