“…Although some studies have shown increases of liver size when fish have been exposed to certain types of contaminants, particularly petroleum hydrocarbons and organic chemicals (Chuiko et al 2007;Yeom et al 2007), other studies have found smaller liver sizes in areas polluted with heavy metals and PCBs (Hinck et al 2007;Roussel et al 2007) in agreement with our results. Raldúa et al (2007) reported more prevalence of liver pathologies in fish at sites with higher wholebody mercury concentrations.…”

Despite many efforts for pollution abatement in aquatic ecosystems, there are still some cases of high accumulation of industrial pollutants due to past activities. In Flix reservoir (Ebro River, Spain), there are around 200,000-360,000 tons of industrial pollutants with a high concentration of heavy metals and organochlorides due to the activity of an organochlorine industry during more than half a century. This exceptional amount of pollutants provides a good opportunity (and need) to analyse their effects on fish populations under natural conditions, which is rarely available to ecotoxicologists. We compared the reproductive traits and prevalence of diseases and parasites at this impacted area with a neighbouring upstream reservoir unaffected by the pollution (reference sites) and also to downstream sites. Deformity, eroded fin, lesion and tumour (DELT) anomalies and ectoparasites were clearly more frequent at the impacted area for several fish species (common carp, roach and pumpkinseed). A significant negative impact of Flix reservoir on condition (eviscerated and liver weights, adjusted for fish size with analysis of covariance) and reproductive traits (gonadal weight and number of mature eggs, adjusted for fish size) was also detected for several fish species. The responses to the pollutants were species-specific, and common carp (Cyprinus carpio) was the species with the clearest effects on fitness-related traits at the impacted area, despite also being among the most tolerant to pollution.

“…Thus, the determination of a correct length-weight relationship was not possible for ESB data. However, usually Fulton's K has been determined by studies dealing with bream (Chuiko et al 2007;Kakareko 2001;Kangur 1996;Tierney et al 1999;Treer et al 2003). Gross (1997), Shul'man (1974) and Weatherly and Gill (1987) stated that lipid content depends on age.…”

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.

“…In many reservoirs, there is a current risk of metal contamination, or the reservoir sediments already contain a burden of heavy metals and organic pollutants accumulated as a consequence of anthropogenic activities. In the Rybinsk Reservoir (Russia), the largest artificial water-body in Europe (4550 km 2 ), industrialization has resulted in contamination with PCBs (Chuiko et al, 2007). Ninety-five percent of PCBs accumulate in bottom sediments (German & Zakonnov, 2003), so after PCB discharge into the water body has been completely eliminated, their presence in the system will still be an ecological hazard for 25-30 years.…”

Highlights of large lake research and management in Europe

Lakes in Europe have a bipolar distribution by latitude with higher lake densities in the north (58-65°N) and south (38-48°N). By area, 95% of the large lakes ([100 km 2 ) are located at altitudes lower than 100 m above sea level (ASL) and only 1% lie higher than 1,000 m ASL. Physically large lakes exhibit several similarities to seas and oceans in their thermal structure and circulation dynamics. From the chemical point of view, lakes are important accumulation sites for substances transported from the watershed or built up in the lake itself but they may contribute positively to global greenhouse gas emission. Fauna and flora of ancient large lakes such as the Caspian Sea and Lake Ohrid include large numbers of endemic species, which become endangered if conditions change because of direct human impact, alien species invasions or climate change. Large lakes offer a wide range of ecosystem services to society, the multiple use of which creates multiple pressures on these water bodies such as nutrient load and toxic pollution, modification of hydrology and shore line structure, and shifting of the food web balance by stocking or harvesting various species. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered.
