“…Traditional fish biomarker responses considered in this study confirmed an elevation of detoxification enzyme activities and oxidative stress parameters in fish sampled downstream from the WWTP. A study carried out on two cyprinid fish species from the same locations in summer 2012, which also included some of the biomarkers considered here (EROD and BFCOD), reached similar conclusions (Blanco et al 2019). According to these authors, males from two species (S. laietanus and Barbus meridionalis) displayed delayed sexual maturation on the polluted site, and females of B. meridionalis expressed gonadal aromatase (an enzyme that converts testosterone to estradiol) induction.…”

“…Former studies carried out in the same area of the Ripoll River, revealed that the site downstream from the textile dye plant, even after wastewater treatment, was still highly polluted (Colin et al 2016(Colin et al , 2017Maceda-Veiga et al 2013;Blanco et al 2019). In this study, several CEC, such as pharmaceuticals, sunscreen compounds, fragrances, antiseptics, fire retardants, surfactants, pesticides and plasticizers were detected in water.…”

Mediterranean rivers are severely affected by pollutants from industry, agriculture and urban activities. In this study we examined how industrial pollutants, many of them known to act as endocrine disruptors (EDCs), could disturb the reproduction of the Catalan chub (Squalius laietanus). The survey was conducted throughout the reproductive period of S. laietanus (from March to July 2014) downstream an industrial WWTP located in the River Ripoll (NE Iberian Peninsula). Eighty fish (28 females and 52 males) were caught by electrofishing upstream and 77 fish (33 females and 44 males) downstream a WWTP. For both sexes, the gonadosomatic index (GSI) and gonadal histology were examined and related to water chemical analysis and fish biomarkers. Female fecundity was assessed using the gravimetric method. Fish from the polluted site showed enhanced biomarker responses involved in detoxification. Also, in the polluted site, lower GSI values were attained in both sexes and females displayed lower numbers of vitellogenic oocytes. Gonadal histology showed that all maturation stages of testicles and ovaries were present at the two study sites but fish males from the polluted site had smaller diameter seminiferous tubules. Water chemical analysis confirmed greater presence of EDCs in the river downstream the industrial WWTP. The chemicals benzotriazole and benzothiazole could be partially responsible for the observed alterations in the reproductive biology of S. laietanus.

“…Despite the comparatively lower exposure to xenobiotics of Squalius laietanus, 11 the decrease of highly unsaturated PCs (36:5,6; 38:5,6; 40:5) was more significant than in B. mediterraneus (PC 40:5). Interestingly, levels of PC-Ps were up to one order of magnitude higher in B. meridionalis than in S. laietanus (Fig.…”

This work applies ultra-high performance liquid chromatography coupled to highresolution mass spectrometry (UPLC-HRMS) to characterize for the first time the lipidome of the skeletal muscle of two fish species (Barbus meridionalis, Squalius laietanus) collected in a Mediterranean River affected by urban and industrial wastewater outflows. The untargeted analysis allowed a clear separation of the lipidome of fish from polluted and reference sites; phosphatidylcholines (PCs), phosphatidylethanolamines (PEs) and their lyso and ether-linked forms were among the distinctive features. The targeted analysis consistently detected a decrease in PC

“…Among the first steps of biotransformation, stand out the induction of 7-ethoxyresorufin-O-deethylase (EROD) activity related to CYP1A (Whyte et al 2000) and benzyloxy-4[trifluoromethyl]-coumarin-O-debenzyloxylase (BFCOD) activity associated to CYP3A (Celander 2011). The combination of both markers in fish has been applied in freshwater fish studies (Blanco et al 2019;Quesada-Garcia et al 2013;Soler et al 2020). CEs are also phase I reactions involved in the hydrolysis of foreign chemicals as well as endogenous compounds (Wheelock et al 2008) with a particular high stoichiometric affinity for organophosphorus pesticides for which a protective role, preventing AChE inhibition, has been awarded (Sanchez-Hernandez and Wheelock 2009).…”

Specimens of two endemic cyprinids, Squalius laietanus (Catalan chub) and Barbus meridionalis (Mediterranean barbel), were sampled from a reference site in a small stream of the Ripoll River (NW Mediterranean) outside of their reproductive season.Biomarkers involved in xenobiotic-mediated responses were individually contrasted in fish of both species and 17 perfluoroalkyl substances (PFASs) analysed in muscle to reveal bioaccumulation trends. The parameters were in muscle: cholinesterases, metabolic lactate dehydrogenase (LDH) and citrate synthase (CS); and in liver: cytochrome P450 dependent activities (EROD and BFCOD), carboxylesterase (CE), glutathione S-transferase (GST), glutathione reductase (GR), glutathione peroxidase (GPX) and catalase (CAT). All markers are considered adaptive defence mechanism to face stress. Sensitivity to a model pesticide: dichlorvos was also contrasted in vitro in muscular acetylcholinesterase (AChE) and hepatic CE to reveal species sensitivity to neurotoxic chemicals. Enzymatic activities related to protective mechanisms such as butyrylcholinesterase (BuChE), CE and CAT were higher in chub whereas the antioxidant defences GR and GPX were higher in barbel. Aerobic CS was also higher in barbel while anaerobic LDH was so in chub. EROD activity did not differ between the two species but BFCOD activity was higher in barbel. Levels of PFAS were higher in barbel likely due to its benthic habitat. The in vitro tests revealed higher sensitivity to dichlorvos of muscular AChE in chub (lower IC50) which was probably compensated by a higher catalytic efficiency of CE. All these former biochemical particularities are discussed in terms of fish ecological performance in front of anthropogenic stressors.
