“…We estimate that yellow catfish spawning occurs from April to June throughout Three Gorges Reservoir. Similar to this study, yellow catfish from Lake Ce (Yangtze River Basin, China) were also found to spawn from May to August, with peak GSI occurring during June and July (Cao et al., ). In Lake Liangzi (Yangtze River Basin, China), reproduction was again found to occur from May to late July (Cao et al., ).…”

“…Cao et al. () also reported a relatively low absolute fecundity for yellow catfish ranging from 657 to 11 696, and other studies reported similar fecundity numbers in Honghu Lake and Poyang Lake, China (794 to ~4873 and 1132 to ~12 412, respectively (Cao et al., ). We recommend that harvesting or fishing effort should likely be managed to target the non‐reproductive seasons of yellow catfish in Three Gorges Reservoir so as to conserve vulnerable spawning stocks.…”

“…China, India, Japan, Korea, Laos, Russia and Vietnam). Throughout China, the species is considered to be relatively common and is commercially exploited throughout the middle and lower reaches of the Yangtze River (Cao et al., ). Due to increasing market demands, the species is also raised in semi‐intensive and intensive aquaculture facilities in the region (Liu, ).…”

Population characteristics of yellow catfish (Peltobagrus fluvidraco ) along the longitudinal profile of Three Gorges Reservoir, China

Summary The length–frequency and age distributions, condition factor (K), gonadosomatic index (GSI) and gastrosomatic index (GaSI) of yellow catfish (Peltobagrus fluvidraco) were studied at three sites along the 500‐km longitudinal profile of Three Gorges Reservoir. Across all three sites (dam, mid‐reservoir and upper reservoir), GSI increased from April through June, with peak values observed in May and June. Mean K and GSI for fish captured near the dam were significantly higher compared to mid‐reservoir or upper‐reservoir areas. The GaSI index showed no significant variations across sites. However, the length‐frequency histogram of yellow catfish in the more riverine upper reservoir was log‐normal and skewed towards larger (total length) fish, a pattern that was significantly different from mid‐reservoir or near‐dam habitats, where fish length data were normally distributed but at a smaller length mode. Age estimations using otolith sagittae revealed that the spawning population was dominated by fish from only two age‐classes (1 and 2). This study provides novel insight into population characteristics of fish along the substantial spatial scale of Three Gorges Reservoir. Given the irregular population size‐ and age‐structure and the fact that the species is currently commercially exploited, this population is believed to be susceptible to overfishing. Restricted harvesting during peak reproductive months is recommended and suggested that additional research is needed on recruitment and harvest dynamics of this species throughout Three Gorges Reservoir. Additional research is also required to determine whether the spike in K and GSI at lentic sites is a transient product of recent impoundment or an indicator of optimal hydrologic habitat for the species.

“…Most mature miRNA sequences are conserved across amphibians, fish, and mammals (Kloosterman & Plasterk, ). Recently, miRNA expression has also been examined in the gonads of fish and mammals, such as allotetraploid hybrid fish and Carassius auratus (Zhou et al, ), P. fulvidraco (Cao et al, ), O. niloticus (Xiao et al, ), P. olivaceus (Lee et al, ), primates (Yan et al, ), and mice (Reid et al, ), using next‐generation sequencing technologies. These studies show that miRNAs are very important for sex differentiation and gonadal development.…”

Integrated mRNA and miRNA expression profile analyses reveal the potential roles of sex‐biased miRNA–mRNA pairs in gonad tissues of the Chinese concave‐eared torrent frog (Odorrana tormota)

The Chinese concave‐eared torrent frog (Odorrana tormota) is typically sexually dimorphic. Females are significantly less common than males in the wild. Until now, the molecular mechanisms of reproduction and sex differentiation of frogs remain unclear. Here, we integrated mRNA and microRNA (miRNA) expression profiles to reveal the molecular mechanisms of reproduction and sex differentiation in O. tormota. We identified 234 differentially expressed miRNAs (DEMs) and 18,551 differentially expressed transcripts. Of these, 12,053 mRNAs and 64 miRNAs were upregulated in testes, and 6,498 mRNAs and 170 miRNAs were upregulated in ovaries. Integrated analysis of the miRNA and mRNA expression profiles predicted 75,602 potential miRNA–mRNA interaction sites, with 42,065 negative miRNA–mRNA interactions. We found 36 differentially expressed genes (DEGs) related to reproduction and sex differentiation, of which 15 DEGs formed 92 negative miRNA–mRNA interactions with 34 known DEMs. Thus, miRNAs may play other important roles in O. tormota. Furthermore, Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses showed reproductive‐related processes, such as the gonadotropinreleasing hormone signaling pathway and ovarian steroidogenesis. Based on functional annotation and the literature, the retinoic acid signaling pathway, the SOX9–AMH pathway, and the process of spermatogenesis may be involved in the molecular mechanisms of reproduction and sex differentiation in O. tormota, and may be regulated by miRNAs. The miRNA–mRNA pairs described may provide further understanding of the regulatory mechanisms associated with reproduction and sex differentiation, and the molecular mechanism of reproduction in O. tormota.
