“…Parsons et al (1977) reported a protein content of about 35 %, and of 40 % for carbohydrates for dinoflagellates. Wynne et al (1982) found an even lower protein content of 203 kgmg-l cell dry weight compared with a carbohydrate content of 325 pg mg -' cell dry weight for P. cinctum. For Skeletonema costaturn, one of the dominant diatoms of the fourth experiment, a content of 58 % protein and of 33 % carbohydrates was found.…”

Consumption of the dissolved compounds of phytoplankton detritus (dinoflagellates, diatoms) by natural bacterial populations of the Kiel Bight area was studied. Experiments simulated the situation during degradation of a phytoplankton bloom in the water column, when high concentrations of dissolved organic material are released. The experiments were conducted in a chamber which allowed continuous monitoring of the oxygen concentratlon. Subsamples were taken at short time intervals for determination of bacterial number and biomass, and of dissolved organic compounds (concentration and molecular weight). These experiments allowed evaluation of the bacterial biomass increase in the absence of predators, without addihon of a labelled substrate. The bacteria consumed dissolved substances very rapidly, resulting in an increase of bacterial biomass of more than 500 figCl-Id-'. It was shown by oxygen measurements, that up to 80 % of the bacterial gross uptake was respired. This indicates the importance of bacteria as remineralizing organisms in the water column.

“…m-2 (Pollingher 1980) or, over the entire lake area, a total of about 25,500 tonnes wet wt. Since Peridinium cells have an average content of about 20% carbon and 1.6% nitrogen (Berman 1978;Wynne et al 1982) this biomass represents about 5,100 tonnes C and 4 10 tonnes N. Thus, from the rates noted above for photosynthetic carbon fixation and nitrogen uptake, we estimate a 6-fold turnover for carbon and a 19-fold turnover for nitrogen during the bloom season.…”

Seasonal and diurnal patterns of NH,+ and NO,-uptake were determined for Lake Kinneret phytoplankton. Nanoplankton generally, but not always, had a higher uptake of NH,+ and NO,-than did net plankton. Ammonium was always taken up preferentially and the phytoplankton had lower apparent affinity constants (K,) for this ion than for N03-. However, during the annual dinoflagellate bloom of Peridinium (February-May), when ambient levels of NH,+ were low and those of N03-were high, a considerable portion of the total N flux was derived from NO,-. The observed daily fluctuations of specific uptake rates for both NH;' and NOJ-can be partially explained by changes in light intensity. The finding that N03-was utilized by the dinoflagellates implies that control of the amounts of this nutrient, which is predominantly supplied from watershed sources, could be important in limiting eutrophication in Lake Kinneret.

“…In countries around the world, the few freshwater red tides of dinoflagellates reported in natural lakes have included those caused by Peridinium cinctum in Lake Kinneret in Israel (20)(21)(22)(23), and by Peridinium penardii in Lake Clear in the USA (24). In many cases, the mass propagation of the dinoflagellate Peridinium results from eutrophication caused by nutrients such as nitrogen and phosphorus; however, some reports have indicated the roles of organic nutrients and trace elements, e.g., Ca, and much remains unclear (25,26).…”

Objective: The aim of this study is to clarify the long-term dynamics of the red tide occurring in Lake Kawaguchi.Methods: The measurement of environmental factors and water sampling were carried out monthly at a fixed station in Lake Kawaguchi's center basin from April 1993 to March 2004. On June 26, 1995, the horizontal distribution of Peridinium bipes was investigated using a plastic pipe, obtaining 0~1-m layers of water column samples at 68 locations across the entire lake.Results: P. bipes showed an explosive growth and formed a freshwater red tide in the early summer of 1995, when the nutrient level was higher than those in the other years, particularly the phosphate concentration in the surface layer. The dissolved total phosphorus (DTP) concentration was sufficient for P. bipes growth in that year. In the study of its horizontal distribution, P. bipes was found at all the locations. The numbers of cells per milliliter ranged from 67 to 5360, averaging 1094±987 cells/ml, with particularly high densities along the northern shore. Since then, P. bipes has annually averaged about 25 cells/ml in Lake Kawaguchi.Conclusion: We observed that the red tide caused by P. bipes correlates with a high DTP concentration in Lake Kawaguchi.
