Abstract Keinänen, M., Uddström, A., Mikkonen, J., Casini, Pönni, Myllylä, T., Aro, E., and Vuorinen, P. J. 2012. The thiamine deficiency syndrome M74, a reproductive disorder of Atlantic salmon (Salmo salar) feeding in the Baltic Sea, is related to fat content prey fish. – ICES Journal Marine Science, 69: 516–528. This study clarifies how diet leads eggs, consequently M74 mortality yolk-sac fry. main species, sprat (Sprattus sprattus) herring (Clupea harengus membras), their biomass Proper...
Abstract Conventional tags applied to individuals have been used investigate animal movement, but these methods require tagged be recaptured. Maps of regional isotopic variability known as “isoscapes” offer potential for various applications in migration research without tagging wherein isotope values tissues are compared environmental values. In this study, we present the spatial oxygen ( ) and dissolved inorganic carbon (δ 13 C DIC Baltic Sea water. We also provide an example how isoscapes...

Occurrence and distribution of perfluoroalkyl acids (PFAAs), a sub-category per- polyfluoroalkyl substances (PFASs), is widespread in the environment. Food, especially fish meat, major pathway via which humans are exposed to PFAAs. As an integral part Nordic diet, therefore, this study, several species, caught selected Baltic Sea basins freshwater bodies Finland, were analysed for Perfluorooctane sulfonate (PFOS) was detected all samples >80% from freshwaters. PFOS contributed between 46...
The adverse effects of high temperatures on the early life stages anadromous whitefish Coregonus lavaretus were experimentally examined by assessing fertilization success, percentage developmental abnormalities, cumulative mortality and rate embryogenesis across a range temperatures. Temperatures >or= 7 degrees C increased proportion unfertilized abnormally dividing eggs, deformed embryos consequent mortality. higher temperature, more severe effects. When eggs fertilized constantly incubated...
Radiation reactions in the lungs were studied clinically and radiologically 74 bronchial carcinoma patients treated by split-course method 33 similar conventionally continuous high-energy radiation. The radiation milder after management appeared two months later than radiotherapy. observations show good agreement with theoretical background of method.
Abstract Torniainen, J., Vuorinen, P. Jones, R. I., Keinänen, M., Palm, S., Vuori, K. A. and Kiljunen, M. 2014. Migratory connectivity of two Baltic Sea salmon populations: retrospective analysis using stable isotopes scales. – ICES Journal Marine Science, 71: 336–344. refers to the extent which individuals a migratory population behave in unison, has significant consequences for ecology, evolution conservation animals. We made assessment River Simojoki Kymijoki populations Atlantic Salmo...
Sprat (Sprattus sprattus) and small herring (Clupea harengus) are the dominant prey fish of Atlantic salmon (Salmo salar) in Baltic Sea. If fatty acid (FA) proportions sprat differ, dietary history ascending could be determined from their FA profiles. Therefore, we investigated composition several age groups whole herring, caught three main feeding areas autumn spring. Oleic (18:1n-9) was most prevalent characteristic this species. In palmitic (16:0) common FA, but lipid characterized by n-6...
Baltic herring and sprat were sampled between October 1994 January 1995 off the southern coast of Finland around Åland Islands. From this material fish 135–159 mm in length, a size class that was assumed to be preferred as prey by salmon, selected grouped according species, sex age. Herring 1–3 years 3–13 old. In addition, one group smaller, two-year-old, female selected. Thus twenty groups formed prepared whole-fish homogenates. Thiamine quantified from all homogenates, while male analysed...
