Phytoplankton was sampled over 10 months at five stations along the north-eastern coast of Lake Tanganyika. The biomass is composed chiefly of diatoms together with blue-green algae and, occasionally, green algae and Euglenophytes. Seasonal changes in phytoplankton composition and densities are discussed in relation with abiotic factors.
Résumé
Des prélèvements de phytoplancton ont été effectués pendant 10 mois le long de la côte nord-est dans 5 stations du Lac Tanganyika. La majeure partie de la flore algale est constituée le plus souvent par les Bacillariophycées et les Cyanophycées et, plus rarement, par des Chlorophycées et des Euglenophycées. Les changements de la structure du peuplement phytoplanctonique et de la densité cellulaire sont analysés en rapport avec les facteurs abiotiques.
