salmon spawning rivers.
It was stated, that in typical small salmon stream the Indyora River (the Kola Peninsula) the Atlantic salmon (Salmo salar) parr and common minnow (Phoxinus phoxinus) practically do not compete for the food resources, in spite of their high density. Minnows feed on filamentous algae, and salmon parr − exclusively on aquatic and airy insects. Eggs of the pink salmon (Oncorhynchus gorbuscha) over its spawning period serve as significant addition to the salmon parr ration.

Peculiarities of anabolic activity of tissues of the bivalve mollusk Anadara inaeguivalvis in norm, under food deficit and experimental anoxia have been studied. It was shown that in normal conditions processes of the protein synthesis, assessed by total RNA content and index RNA/DNA, were tissue-specific. Under food deficit these processes in gills, hepatopancreas and podium were differently directed. In gills biosynthesis rate was stable, in podium tissues it decreased 1.3 times. Under external anoxia anabolic activity in gills and hepatopancreas decreased, at this processes of the protein catabolism became more intensive. Podium tissues were characterized by active protein metabolism: intensification of RNA synthesis and increase of the amino acids pool.

The method has been developed of the bottom sediments toxicity assessment using two species of the aquatic invertebrates − benthic Chironomus riparius and planktonic Daphnia magna. The method can be used also for analysis of the toxicants' bioavailability in the model experiments at the toxicants' adding either to the bottom sediments or to water. Reliability of the method has been shown in analysis of the natural bottom sediments with different toxicity rate.

Results of long-term studies on the content of 137Cs in the water and suspended matter of the Danube River are given in the paper. The average per month and the average per year concentrations of 137Cs, and also its monthly and annual transfer through the Danube River delta, were calculated. Long-term tendencies of contamination and ecological periods of 137Cs half-decay in the water and suspended matter were assessed. The coefficients of 137Cs distribution between solid and liquid phases of migration were calculated. Additional contamination conditioned by industrial activities (spills from nuclear power plants and radiation accidents) was revealed and assessed. Results of the study can be used in calculating parameters of 137Cs migration over food links, and also in calibrating the models of 137Cs river transport.

Paper deals with original material and literature data on the parasites of fishes, unintentionally introduced from the Far East into the water bodies of Ukraine. Parasitofauna of Pseudorasbora parva, Perccottus glenii and Carassius gibelio is presented accordingly by 12, 8 and 60 species, among them accordingly 2,1 and 32 species are parasites-invaders and 7, 5 and 34 species are of epizootic significance. The fauna of fish parasites in Ukraine was enriched by 35 species-invaders, which penetrated at occasional introduction of their hosts.

molecular mass distribution.
The content of Al, Mn, Cu, and Cr was studied in the water of the rivers of the Pripyat River basin characterized by a rather high concentration of humus substances. The highest content was typical to Al(III), which was followed by manganese, copper, and chromium. Relationship between suspended and dissolved forms of the studied metals was investigated. It has been found that the suspended from of migration is typical to aluminum and chromium. A large portion of manganese was observed in the dissolved state, which was conditioned by the formation of complexes with humus substances. Copper occurred mainly in the dissolved form. Rather high concentrations of dissolved aluminum often prevailing over its suspended form were observed in the rivers with the highest content of humus substances. Humus substances are of considerable importance in the formation of complexes, which results in the predominance of anionic complexes of metals. The compounds with the molecular mass ≤ 2.0 kDa prevail among them.
