Abstract
Domestication is the process of modifying the phenotype of a population through anthropic selection from human perspectives. Successive generations of domestication have influenced the physiological characteristics of tench Tinca tinca. In current study, we investigated gene and protein expression alterations in the liver of fifth-generation (F5). A total of 420 genes were found to be upregulated and 351 genes were downregulated, while 410 proteins were upregulated and 279 proteins were downregulated in domesticated T. tinca (DT). The integrated analysis of omics data revealed a total of 55 genes/proteins exhibiting consistent upregulation and 12 genes/proteins displaying consistent downregulation in DT. The upregulated genes/proteins in DT, such as SSR1, DERLIN2, OS9, DNAJB11, and HYOU1, exhibit enrichment in the protein processing in the endoplasmic reticulum pathway. Additionally, upregulated genes/proteins such as IL2RB, F13B, and IRF3 are associated with immune response. Conversely, downregulated genes/proteins in DT, including HSD11B1, CYP24A1, and COMT, play roles in hormone metabolism. These findings indicate that domestication can have a substantial impact on the physiological modifications related to protein processing, immune response, and hormone metabolism in DT. These adaptations potentially enhance their ability to thrive in artificial aquaculture environments, leading to improved growth and development. The exploration of genetic changes in DT will not only improve aquaculture practices but also provide significant insights into the broader process of domestication and its effects on physiological functions.

Abstract
Little is known about sediment-bound exposure of fish to endocrine disrupting chemicals (EDC) under field conditions. This study aimed to investigate potential routes of EDC exposure to fish and whether sediment-bound contaminants contribute towards exposure in fish. Tench (Tinca tinca) and roach (Rutilus rutilus) as a benthic and pelagic living fish species, respectively, were sampled at the Luppe River, previously described as a "hotspot" for accumulation of EDC in sediment. A field reference site, the Laucha River, additionally to fish from a commercial fish farm as reference were studied. Blackworms, Lumbriculus variegatus, which are a source of prey for fish, were exposed to sediment of the Luppe River and estrogenic activity of worm tissue was investigated using in vitro bioassays. A 153-fold greater estrogenic activity was measured using in vitro bioassays in sediment of the Luppe River compared the Laucha River. Nonylphenol (NP; 22 mg/kg) was previously identified as one of the main drivers of estrogenic activity in Luppe sediment. Estrogenic activity of Luppe exposed worm tissue (14 ng 17β-estradiol equivalents/mg) indicated that food might act as secondary source to EDCs. While there were no differences in concentrations of NP in plasma of tench from the Luppe and Laucha, vitellogenin, a biomarker for exposure to EDCs, was induced in male tench and roach from the Luppe River compared to both the Laucha and cultured fish by a factor of 264 and 90, respectively. However, no histological alterations in testis of these fish were observed. Our findings suggest that sediments substantially contribute to the overall EDC exposure of both benthic and pelagic fish but that the exposure did not impact gonad status of the fish.

Abstract
Alterations of sperm quality were studied in tench (Tinca tinca) exposed to sub-lethal doses of 17-alpha-ethynylestradiol-EE2-(50, 100 and 500μg/kg t.w) under semi-static conditions for 30 days. Thus, different biomarkers of sperm quality were assessed: concentration and volume of ejaculate, total number of spermatozoa, percentage of motile spermatozoa, sperm motility and percentage of live and dead spermatozoa. Sperm motility was examined by computer-assisted image analysis and the viability of spermatozoa was assessed through flow cytometry. The most relevant alterations observed were significant reductions in the reproductive parameters such as testicular somatic index, spermatozoa concentration, straight line velocity, curvilinear velocity, average path velocity and wobble in tench exposed to 50μg/kg t.w of EE2. Our study about the effects of EE2 on the sperm quality in tench provides new evidences which strengthen the fact that this synthetic estrogen is included in the list of non-monotonic dose response compounds in animal studies.

Abstract
Environmental pollution with synthetic estrogens may pose a serious threat to reproduction of aquatic wildlife species. The current study describes the effects of 17α-ethynylestradiol (EE2 ) on the structure of the testis in tench (Tinca tinca). Adult male tench were exposed to sublethal doses of EE2 (50, 100, and 500 μg/Kg t.w.) under semistatic conditions for a period of 30 days. The condition factor (CF), testicular somatic index (TSI), and histology (including a morphometric analysis) of the testis were examined. No consistent differences were observed in the CF of EE2 -exposed tench when compared with nonexposed fish. A significant decrease in TSI could only be observed at a 50 μg/Kg t.w. EE2 dose (p < 0.05) when compared with the control group. The histopathology of the testis was associated with loss of normal tubular structure with increased doses of exposure, decrease of tubule number, degeneration in Sertoli and Leydig cells, increase in necrotic testicular cells including formation of syncytia structures and, finally, a high incidence of fish with early primary oocytes at 100 and 500 μg/Kg t.w. EE2 . These results indicate that long-term exposure to EE2 may produce clear negative effects on testicular structure in tench.

Abstract
Human-aided dispersal can result in phylogeographic patterns that do not reflect natural historical processes, particularly in species prone to intentional translocations by humans. Here, we use a multiple-gene sequencing approach to assess the effects of human-aided dispersal on phylogeography of the tench Tinca tinca, a widespread Eurasian freshwater fish with a long history in aquaculture. Spatial genetic analysis applied to sequence data from four unlinked loci and 67 geographic localities (38-382 gene copies per locus) defined two groups of populations that were little structured geographically but were significantly differentiated from each other, and it identified locations of major genetic breaks, which were concordant across genes and were driven by distributions of two phylogroups. This pattern most reasonably reflects isolation in two major glacial refugia and subsequent range expansions, with the Eastern and Western phylogroups remaining largely allopatric throughout the tench range. However, this phylogeographic variation was also present in all 17 cultured breeds studied, and some populations at the western edge of the native range contained the Eastern phylogroup. Thus, natural processes have played an important role in structuring tench populations, but human-aided dispersal has also contributed significantly, with the admixed genetic composition of cultured breeds most likely contributing to the introgression.
