ABSTRACT. The research objective was to assess the health of sea trout from the Pomeranian rivers Słupia, Wieprza, Parsęta, and Rega in 2010. Microbiological, hematological, and immunological examinations were performed. In total, twelve gram-negative bacteria species were isolated and identified; they belonged to the families Pseudomonadaceae, Enterobacteriaceae, and others. The gram-positive bacteria isolated belonged mainly to the genus Streptococcus. Immunological and hematological examinations did not reveal statistically significant differences among samples. In comparison to previous examinations, the quantity of infected fish was significantly lower.
