“…The bream (Abramis brama) is a freshwater species that is widely used for biomonitoring in Europe (Chuiko et al 2010;Farkas et al 2003;Koponen et al 2003;Nagelkerke and van Densen 2007;Pulkrabová et al 2007;Rask et al 2010;Sawal et al 2011;Svobodova et al 1999;Rüdel et al 2011). However, the effects of environmental stressors on fish are hard to interpret because of the complexity of the environment itself (Adams and Ryon 1994).…”

Piscifaunal health depends upon the state and quality of the aquatic environment. Variations in physical condition of fish may therefore be attributed to changes in environmental quality. Based on time series of up to 20 years of biometric data of bream from multiple sampling sites of the German environmental specimen bank (ESB), this study assessed whether changes in biometric parameters are able to indicate long-term alterations in fish health and environmental quality. Evaluated biometric parameters of fish health comprised length and weight of individuals of a defined age class, the condition factor, lipid content and hepatosomatic index (HSI). Although there are negative trends of the HSI, the overall development of health parameters can be interpreted as positive. This seems to suggest that health parameters conclusively mirror the long-term improvement of water quality in the selected rivers. However, the applicability of the condition factor as well as lipid content as indicators for fish health remained subject to restrictions. Altogether, the results from the ESB confirmed the high value of biometric parameters for monitoring of long-term changes in state and quality of aquatic ecosystems.

“…The PCB contents were determined by high resolution chromatographymass spectrometry at the Laboratory of Analytic Ecotoxicology at the Severtsov Institute of the Prob lems of Ecology and Evolution, Russian Academy of Sciences. The PCB content was 50.76 ng/g wet weight in the fish from the Sheksna reach and 3.65 ng/g wet weight from the Mologa reach; the sediment PCB contents were 425.6 ng/g and 24.8 ng/g dry weight (gray and sandy silts) from these reaches, respectively [15]. The experimental fish were sampled and ana lyzed at the beginning of the experiment (day zero) and 40, 96, and 218 days later.…”

The chronic effect (duration of exposure 218 days) of polychlorinated biphenyls (PCBs) and the prolonged effect of the short term action of chlorophos or of N methyl N' nitro N nitrosoguanidine (MNNG) during embryogenesis upon the sensitivity of intestinal glycosidases to Cu and Zn was studied in roach (Rutilus rutilus (L.) underyearlings. The Cu +2 and Zn +2 ions at concentrations ranging from 0.1 to 25 mg/L in vitro cause a 10-77% decrease in amylolytic activity in the intestinal mucosa of control roach. An elevated level of PCBs (50.8 ng/g wet weight of food and 426 ng/g dry weight of ground) increased the sen sitivity of glycosidases to Cu and Zn. The embryotoxic action of chlorophos at concentrations of 1 × 10 -6 -1 × 10 -2 mg/L in most cases increased the inhibitory effect of Cu but decreased that of Zn. As a rule, MNNG (3 × 10 -7 -3 × 10 -1 mg/L) reduced the glycosidase sensitivity to the effect of metal ions. The magnitude and direction of the effect depend on the nature and concentration of toxicants.

“…Correspondingly, the Volzhskii, Molozhskii, and Sheksninskii Reaches are considered, as is the Glavnyi Reach. The spatial pollution inhomogeneity of the Rybinsk Reservoir ecosystem with various pol lutants, such as heavy metals (HMs), polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs), has been demonstrated earlier [8,15,17,18]. The main local source of chemical pollution for this reservoir is the Cherepovets industrial complex (ChIC).…”

The breams living in five regions of the Rybinsk Reservoir with different degrees of anthropogenic load have been assayed for the characteristics of their antioxidant system (AOS) and lipid peroxidation (LPO) system. Individuals caught at two stations in the Rybinsk Reservoir that maximally differ in the degree of pol lution display different qualitative and quantitative compositions of polychlorinated biphenyls (PCBs). At the station at the Sheksninskii Reach, which is located near a local source of pollution (Cherepovets), the total content of PCBs and homologous groups of congeners is one order of magnitude higher than in the bream living at the station of the comparatively clean Molozhskii Reach. The AOS response and the generation intensity of LPO products in the bream (Abramis brama L.) liver caused by different degrees of anthropogenic pollution have been determined. The content of LPO products in the liver of the breams caught in the Shek sninskii Reach is considerably higher and the values of AOS characteristics are considerably lower than in the fish from the Molozhskii Reach. The bream living in the Molozhskii and Volzhskii Reaches are in a more favorable state than those in the Sheksninskii Reach. The AOS and LPO characteristics are an appropriate biomarker for estimating the state of the health of the fish.
