“…Fluctuations in water salinity frequent in such water force the fish entering these zones to consume more energy for osmotic and ionic regulations, which means less energy dedicated to the growth and development [ 1 , 2 ]. Fish gametes, developing embryos and juvenile individuals are particularly sensitive to changes in water salinity [ 3 , 4 , 5 ]. However, the organisms most sensitive to water salinity are fish larvae in the early stage of development [ 6 , 7 ].…”

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.

“…Current investigations in many research centres focus on determining the ability of various taxa to survive in water where salinity has occurred rather than on increasing the effects of rearing using saline water. The described experiment on blue bream larvae fits perfectly into this issue, as developing embryos and early-stage fish larvae, in addition to fish gametes, are particularly sensitive to changes in water salinity [ 13 , 14 , 15 , 16 , 28 , 45 , 46 ]. Freshwater fish are exposed to saline water not only when they are in the intertidal zone or when migrating from fresh to saline waters, but also while in their natural habitat.…”

“…Saline pollution creates a permanent chemical impact on aquatic biocenosis [ 12 ]. This is especially true for organisms with low mobility and those that are sensitive to changes in water salinity, such as juvenile stages of fish, molluscs, benthic crustaceans, and insect larvae [ 13 , 14 , 15 , 16 ]. The runoff of saline water with an inert composition into watercourses can lead to the extinction of sensitive populations of fish and other organisms living in a particular section of a river [ 17 ].…”

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.

Bonisławska M., Szulc J., Formicki K. 2015. The effect of water salinity on the motility of spermatozoa of the brook trout, Salvelinus fontinalis (Actinopterygii: Salmoniformes: Salmonidae). Acta Ichthyol. Piscat. 45 (2): 143-151.Background. Salmonid spermatozoa are characterised by a very short time of activity in the water, therefore sudden water pollution in the form of increased salinity on the spawning grounds may have a negative effect on the sperm motility parameters, thus affecting the subsequent egg fertilisation and, consequently, the number of hatched individuals of the species. The aim of this study was to determine the effect of water salinity on the motility parameters of spermatozoa of brook trout, Salvelinus fontinalis (Mitchill, 1814). Material and methods. Sperm motility was monitored with a camera (Basler A312fc) coupled with Nikon Eclipse 50i light microscope from the moment of their activation (contact with water) until the cessation of movement. The following water-salinity treatments were tested: 1.0‰, 3.0‰, 5.0‰, and 10.0‰. The motility parameters: VCL, VSL, VAP, ALH, BCF, LIN, STR, WOB, and MOT, were analysed with Computer Assisted Sperm Analysis (CASA). Results.The mean values of the studied motility parameters of the brook trout spermatozoa (obtained within 30 s), whose activation took place in the water of 0.35‰ salinity and in water of 1.0‰ and 3.0‰ salinity, did not differ signifi cantly. The highest mean values of motility parameters were recorded for the water of 5.0‰ salinity. The 10.0‰ treatment caused a distinct decrease in the values of all the studied parameters. The percentage of MOT was the highest (37.5%) in the sample activated in the water used for fi sh rearing (0.35‰). In the remaining samples the MOT was lower, and in the water of 10.0‰ salinity it was only 9.1%. No spermatozoa movement of any kind was recorded in the 35th second of the experiment. Conclusion.The values of the motility parameters as well as the percentage of motile spermatozoa (MOT) in the semen decrease with increasing salinity of the water used for activation, and with increasing time of exposure.
