title: Relationship between isotope composition of sulphur in sulphate dissolved in river water and sulphur extracted from fish scales.
abstract: More than 100 trouts captured in more than 20 rivers from Poland have been analysed. Only fish caught by trout fishermen were used for this study. Isotope compositions of sulphur (δ(34)S) and carbon (δ(13)C) of fish scales were examined together with δ(34)S from sulphate dissolved in river, as well as patterns of fish diet. We predominantly examined adult fish, at least 4 years old. A scatter of isotope values occurred among the samples obtained from fish caught in different rivers and also for fish caught in the same river. The scatter of the δ(34)S values was much larger than that of δ(13)C values. We noticed the relationship between δ(34)S of scales and δ(34)S of riverine sulphate. There is also a significant difference between isotope compositions obtained for different fish species, which can be attributed to their different diet.
