Abstract
Culter alburnus (topmouth culter)is an economically valuable freshwater fish. However, its insufficient tolerance to dissolved oxygen (DO) and ammonia nitrogen (AN) hinders its industrialisation. 360 experimental fish (4.87 ± 1.10 g) were placed in breathing chambers (oxygen level was 0.70-6.50 mg/L) or water tanks (control AN, 0 mg/L; low AN, 8 mg/L; high AN, 16 mg/L). This study analysed the effects of DO and AN on C. alburnus at physiological, biochemical, and molecular levels. (1) Physiology level: the floating point, coma critical point, and coma point at 20 °C group were significantly higher than those at 30 °C. The oxygen consumption rate of C. alburnus at 20 °C, 25 °C, and 30 °C was (256.65 ± 25.87), (470.47 ± 83.84), and (520.87 ± 55.40) mg/kg.h. The LC50 of AN after 96 h was 24.13 mg/L, and the safe concentration was 2.41 mg/L. The survival rate in the high AN group was significantly lower than that in the other two groups. (2) Biochemistry level: The change curves of antioxidant enzyme activity in the liver tissue under hypoxic stress reached a maximum at 12 h and then decreased. In addition, the increase and decrease in enzyme activity (except malondialdehyde) in the high AN group was lower than that in the low AN group. (3) Molecular level: the angiotensin-converting enzyme and carboxypeptidase genes were the major differentially expressed genes (DEGs) in hypoxic stress, and the DEGs were mainly enriched in the ABC transporter signal transduction pathway. In addition, the serum/glucocorticoid-regulated kinase, stearoyl-CoA desaturase, and 3-hydroxy-3-methylglutaryl-coenzyme A reductase genes were among the major DEGs under high AN stress. The DEGs were mainly enriched in steroid biosynthesis or glycine, serine, and threonine metabolism transporter signal transduction pathways. In summary, it is necessary to focus on the DO and AN during C. alburnus breeding.

Abstract
Interspecific hybridization has the potential to increase animal genetic diversity, enable the introgression of advantageous genetic variation, and even create hybrid lineages. Using the low-coverage whole-genome sequencing data of black Amur bream (Megalobrama terminalis [SJ]), topmouth culter (Culter alburnus [QZ]), and their hybrid progeny, we focused on the sequence variation and contribution bias to the genomic composition of the hybrid lineages of SJ♀ × QZ♂ [ZJ] and QZ♀ × SJ♂ [FJ]. Both mash-based genetic distance analysis and variant analysis based on various reference genomes revealed that the hybrid lineages' genomes are more prone to QZ composition. Furthermore, we assess the degree of subgenomic intermixing between parents QZ and SJ in the FJ and ZJ hybrid lineages. In the Jaccard index-zero genomic area, 89.41% of the genomic region in ZJ and 90.23% in FJ are entirely from one of the parental genomes. This genomic area is primarily from QZ, regardless of FJ or ZJ. In FJ, the proportion is 55.70%; in ZJ, the proportion is 54.60%. Using the reference-free variant discovery tool, we identified two InDel markers (Both were SSR-type InDel markers) and one (T/A)-type SNP marker that displayed differences in agarose electrophoresis. Our current findings suggest that parental genomic contribution bias leads to an imbalance in the genomic composition of hybrid lineages. The genomic composition bias is connected to species but not maternal effects, giving insights into the development of vertebrate genomes shortly after hybridization.

Abstract
In fish, type I IFNs are classified into three groups, i.e. group one, group two and group three, and further separated into seven subgroups based on the number of conserved cysteines and phylogenetic relationships. In the present study, four type I IFNs, named as IFNϕ1, IFNϕ2, IFNϕ3, IFNϕ4, as reported in zebrafish, were identified in a cyprinid, the topmouth culter, Culter alburnus, a species introduced recently into China's aquaculture. These IFNs may be classified as IFNa, IFNc, IFNc and IFNd in a recent nomenclature, with IFNa and IFNd having two cysteines in group one, and IFNc four cysteines in group two. These IFNs, together with their possible receptors, IFNϕ1, IFNϕ2, IFNϕ3, IFNϕ4, and CRFB1, CRFB2 and CRFB5 have an open reading frame (ORF) of 540, 552, 567, 516 bp, and 1572, 1392, 1125 bp, respectively. These IFNs have high amino acid sequence identities, being 91.1-93.6% and 66.9-77.3%, with those in grass carp and zebrafish, respectively, and are expressed constitutively in organs/tissues examined in the fish. The expression of these IFNs can be further induced following poly (I:C) stimulation. However, the possible function of these IFNs and their signalling pathway are of interest for further research.

Abstract
Estrogen could lead to abnormal modulation or disruption of physical development, reproduction and sexual behavior in aquatic wildlife, especially in fish. Information on the toxicity of estrogens to native species in that can be used in site-specific risk assessments is scarce. In the present study, one zona pellucida 3 (ZP3) homologue termed CaZP3 was firstly identified from topmouth culter Culter alburnus, following its structural characteristics, tissue distribution and transcriptional modulation to 17α-ethinylestradiol (EE2) exposure were investigated. Meanwhile, vitellogenin (VTG) gene was employed to provide a comparison of the reactive ability to EE2 induction. The CaZP3 characterized with analogical functional domains such as ZP domain, SP, IHP, EHP, 12 cysteine residues, one N-linked glycosylation site and two conserved O-linked glycosylation sites and equal number of eight exons and seven introns with ZP3 counterparts of higher species. CaZP3 mRNA predominantly expressed in ovary, besides, highly expressed in female heart and male muscle and relatively high expressed in testis. CaZP3 has the lower reactive ability to EE2 induction in comparison with VTG, however, CaZP3 transcripts were significantly induced in gonads of both male and female culter by EE2 and could be used as an alternative biomarker to monitor EE2 activity. The present results supplement the database for toxicity of EE2, especially for fish species endemic to China and provide some useful information for the monitoring of EE2 activity in aquatic environment.
