Active carbon uptake in , and ,. , (Phaeophyta) is driven by a proton pump in the plasma membranesing several inhibitors for different types of carbon uptake across the cell membrane. Throughout the experiments total carbon decreased in concert with a pH increase while alkalinity stayed relatively stable. Addition of acetazolamide had a strong inhibitory effect on the carbon uptake rate in . an

The effects of turbidity and light intensity on the consumption of mysids by juvenile perch (, L.)on and other physical disturbances. Visually feeding fish, such as perch, which depend on clear water and good light conditions for effective foraging are often negatively affected by turbidity. We tested the following hypothesis: in laboratory experiments increased turbidity combined with decreased

The growth of pikeperch (, L.) and perch (, L.) under different water temperature and salinity conditer basin, while salinity in the coastal waters varies between of 4.9–6.8 psu. In the Curonian Lagoon water temperature is generally higher than in the coastal waters. Field studies of growth and condition characteristics of pikeperch and perch were carried out in these water bodies with the aim to
