“…These findings corroborate the results of other studies (Kestemont, Rinchard, Damoiseau, & Tans, 2001;Maddams & McCormick, 2012), while they are not consistent with some other evidences (Chattopadhyay, 2017;Heins et al, 2004). The possible reasons for these non-significant results could be using almost the equal-sized females (Beldade et al, 2012;Benton, St Clair, & Plaistow, 2008), applying same induced breeding technique (Das et al, 2016;Szabó, Urbányi, Müller, Szabó, & Horváth, 2019), providing less stress (Contreras-Sánchez et al, 1998;Mylonas, Fostier, & Zanuy, 2010) and feeding with optimum diet (Izquierdo, Fernández-Palacios, & Tacon, 2001;Rahman, Rahman, Hossain, Yeasmin, & Asif, 2016), etc.…”

“…Thus, the predominance of H. molitrix haplotypes among the hybrid individuals in Lake Balaton was expected, in contrast to the observed 45%. In the case of hormonally induced propagation under aquaculture conditions, the water level increase is not a limiting factor of reproduction [46]. In addition, the production of hybrid bigheaded carps is part of the aquaculture practice [47,48]; therefore, the proportion of bighead carp haplotypes may increase.…”

Bigheaded carps (bighead carp, Hypophthalmichthys molitrix, and silver carp, Hypophthalmichthys nobilis) and their hybrids play an important ecological and economic role in their original habitat, while their introduced stocks may pose serious ecological risks. To address questions about the persistence and invasiveness of these fish, we need to better understand their population structures. The genetic structures of bigheaded carp populations inhabiting Lake Balaton and the Tisza River were examined with ten microsatellite markers and a mitochondrial DNA marker (COI). The Lake Balaton stock showed higher genetic diversity compared with the Tisza River stock. Based on hierarchical clustering, the Tisza population was characterized only by only silver carps, while the Balaton stock included hybrid and silver carp individuals. All COI haplotypes originated from the Yangtze River. Based on the high genomic and mitochondrial diversity, along with the significant deviation from H–W equilibrium and the lack of evidence of bottleneck effect, it can be assumed that bigheaded carps do not reproduce in Lake Balaton. The present stock in Balaton may have originated from repeated introductions and escapes from the surrounding fishponds. The Tisza stock consists solely of silver carp individuals. This stock appears to have significant reproductive potential and may become invasive if environmental factors change due to climate change.

“…Bighead carp (Hypophthalmichthys nobilis) is one of the most important cultured fishes in Asia, which provides a large amount of high-quality protein for human beings [13]. Principally produced in China, the global production of bighead carp reached 3.14 million tons in 2018 (FAO).…”

Background Head of fish species, an exquisitely complex anatomical system, is important not only for studying fish evolution and development, but also for economic values. Currently, although some studies have been made on fish growth and body shapes, very limited information is available on the molecular mechanism of head development. Results In this study, RNA sequencing (RNA–Seq) and small RNA sequencing (sRNA–Seq) technologies were used to conduct integrated analysis for the head of bighead carp at different development stages, including 1, 3, 5, 15 and 30 Dph (days post hatch). By RNA-Seq data, 26 pathways related to growth and bone formation were identified as the main physiological processes during early development. Coupling this to sRNA–Seq data, we picked out six key pathways that may be responsible for head development, namely ECM receptor interaction, TNF signaling pathway, osteoclast differentiation, PI3K–Akt signaling pathway, Neuroactive ligand–receptor interaction and Jak–STAT signaling pathway. Totally, 114 important candidate genes from the six pathways were obtained. Then we found the top 20 key genes according to the degree value by cytohubba, which regulated cell growth, skeletal formation and blood homeostasis, such as pik3ca, pik3r1, egfr, vegfa, igf1 and itga2b. Finally, we also acquired 19 key miRNAs playing multiple roles in the perfection of various tissues in the head (such as brain, eye and mouth) and mineralization of head bone system, such as let–7e, miR–142a–5p, miR–144–3p, miR–23a–3p and miR–223. Conclusions Results of this study will be informative for genetic mechanisms of head development and also provide potential candidate targets for the interaction regulation during early growth in bighead carp.
