The research has shown the domination of fluctuative trends in the biomass dynamics for a major-ity of the caught fish species and decrease in the stocks of littoral phytophil fish. The main reason of the fishery breakdown of the pike perch in Łebsko and perch in Sarbsko was exploitation at a too big scale. The resources of the mentioned fish populations were drastically violated in the first decade...
Celem niniejszego opracowania była prezentacja i porównanie sezonowych zmian stężenia substancji biogenicznych oraz określenie poziomu trofii dwóch jezior przymorskich Gardna i Łebska. Jeziora te zlokalizowane są wzdłuż południowego wybrzeża Morza Bałtyckiego. Zaprezentowane rezultaty są wynikiem badań prowadzonych od kwietnia do grudnia 2007 roku. Do celów publikacji na każdym z jezior wyselekcjonowane...
The main aim of the paper is to present general information about hydro-meteorological conditions in the catchment of the Łebsko Lake. In the first part of the article a short description of the most important hydrographic elements of the investigated area (the Łebsko Lake, the Łeba River and its tributaries) was provided. The climatic analysis of local conditions, besides the characteristics of the...
Ciliates constitute an important trophic link in aquatic environments, because they are essential food sources for zooplankton and fish. In this study, the spatial differences in abundance and composition of ciliate communities in relation to varying water salinity were investigated. The study was conducted in the large, brackish, eutrophic lakes Gardno and Łebsko. In the studied lakes, no significant...
