“…Under the influence of a temperature drop, the density of the water increased at this point, which caused a slowdown of the mineral particles sinking towards the bottom and influenced the increase in the electrolytic conductivity of the water. A similar process has also been observed in other reservoirs with a high water electrolytic conductivity (Molenda 2014b(Molenda , 2018).…”

In the Holy Cross Mountains (southern Poland), there are numerous disused quarries. Some of these are filled with water, and some, despite their nearby location, have extremely diverse physicochemical and chemical properties of their waters. One such object is the Wiśniówka Mała reservoir. Its waters contain large amounts of sulfates (> 700 mg/L) and iron (24 mg/L), which are weathering products of rocks containing metal sulfides (mainly pyrite) in the direct drainage zone. As a consequence, there is an increase in the electrolytic conductivity of the water supplying the reservoir, resulting in very low pH values (< 4). This article presents the detailed limnological characteristics of this reservoir and explains the process that led to its water acidification. A control reservoir, Barcza, was also selected for the tests. Although it is also a post-mining excavation, it has a neutral pH and a low concentration of sulfates and iron. The examined reservoirs differ in the hydrochemical type of waters. The Wiśniówka Mała reservoir represents a sulfate-calcium double-ion type (SO 4 2−-Ca 2+) and the Barcza reservoir, a bicarbonate-calcium type (HCO 3 −-Ca 2+). The concentrations of the main ions occurring here are shaped by the lithological features of the surrounding rocks (respectively: Upper Cambrian quartzite sandstones with pyrite mineralization zones, Lower Devonian sandstones cut by mudstones and claystones with tuffite inserts).

“…For decades, an increasing level of salinity within long sections of inland rivers has been observed due to such anthropogenic activities as mining, smelting or the chemical industry as well as the run-offs of high salinity water from stormwater canals in winter. Any influx of saline water has a considerable impact on the biocenosis of local water bodies [ 3 , 60 , 61 ], including the ichthyofauna dwelling in such waters. It is most probable that stenohaline organisms demonstrating anadrome behaviour, living mainly in rivers and often observed in waters with a salinity of a few ppt, will be best adapted to water salinity changes [ 62 ].…”

The effect of water with a salinity 3, 5, 7, 9 and 11 ppt on the growth and survivability of asp Leuciscus aspius (L.) larvae was investigated. A control sample consisted of asp larvae reared up in freshwater (0 ppt). Larvae were fed for 21 days with nauplii of the brine shrimp Artemia salina. Water salinity was observed to have a considerable effect on the growth and survivability of asp larvae. In addition, saline water extended the life span of Artemia salina nauplii, which resulted in their prolonged availability to asp larvae. Asp larvae showed low tolerance to the salinity of water, reaching 9–11 ppt. Depending on the degree of salinity, the mean final weight of larvae varied from 122.6 to 139.4 mg, at body lengths from 23.8 to 25.6 mm, respectively. The best body length increments were recorded among asp larvae maintained in water with a salinity of 3 ppt. Depending on the level of water salinity, the final survivability of asp larvae ranged from 16.9 to 94.5%. The highest and increasing mortality was demonstrated among the larvae reared in water of the salinity equal to 11 ppt. It is not recommended to rear asp larvae in water with a salinity above 7 ppt due to the low survivability and large differences in the body size of the larvae that managed to survive.

“…These are not, however, places on the borderline between fresh and saline waters, but sections of rivers heavily polluted with salts [ 10 ]. In fact, for several decades, there has been an increasing level of salinity in large sections of inland waters created by anthropogenic activities, such as mining, metallurgy, and chemical industries, and as a result of the runoff of highly saline water from stormwater networks during the winter [ 1 , 47 , 48 ]. Point or sectional salinity is not without influence on the biocoenoses of local water bodies, including the resident ichthyofauna [ 1 , 10 , 13 ].…”

This study confirms that blue bream larvae, like asp larvae inhabiting similar environments, also tolerate waters with salinity levels of 3–7 ppt [ 28 ].…”

The influence of water salinities of 3, 5, and 7 ppt on the growth and survival of Ballerus ballerus (L.) larvae was studied. The control group was fish reared in freshwater (0 ppt). The larvae showed high tolerance to water salinities of 5–7 ppt. The mean final weight of the larvae ranged from 48.6 to 64.1 mg, with corresponding mean total lengths from 18.9 to 22.6 mm, depending on the water salinity level. The best larval length increments were recorded in water with salinity of 3 ppt. They were only slightly lower in 0 ppt water, and there were no statistically significant differences between the breeding rates calculated for larvae reared in 3 ppt water. Depending on the salinity level of the water, the final survival rate of the blue bream larvae ranged from 83.5 to 98.6%. The blue bream larvae reared in water with salinity levels of 5 and 7 ppt were statistically smaller than the others, but the results obtained were equally satisfactory.
