The history began in 1948 with the 1st Conference in Wrocław;a record Conference in respect of number of participants and number of paperswas held in Białystok in 1970 (8th Conference) (Table I). This outline is followedby a discussion of scientific problems presented at the nine Conferences held upto the present time. Although these Conferences do not fully reflect the wholerange of hydrobiological studies carried out in Poland, the following tendenciesin development can be observed: 1) Increase in numbers of scientific staff andincrease in number of publications; 2) Increase in the complex character of studiesin which the lake or river is treated as a functional whole, with special attentionon energy flow and circulation of matter in the ecosystem: 3) Development ofstudies on productivity and bioenergetics, as the result of the stimulating influenceof the International Biological Programme; 4) The development in recentyears of studies on protection of waters against pollution and excessive eutrophication;5) The development of experimental studies, both laboratory and fieldones (including experiments on whole ecosystems).In the concluding part of the paper it is emphasised that Polish hydrobiologyrepresents a high world level in the field of production, bioenergetic and trophologicalstudies. The level of research on the problem of water protection againstpollution is also satisfactory, as are the experiments made on whole ecosystems,including experiments on recultivation of lakes. Development of Polish hydrobiologyis delayed in the field of application of new up-to-date research techniques, studies on circulation of matter mechanisms, mathematical modelling and forecastingof processes in ecosystems.}, type={Text}, title={Problematyka hydrobiologiczna w Polsce na tle dotychczasowych zjazdów hydrobiologów}, URL={http://www.rcin.org.pl/Content/153858/PDF/WA058_109470_P3259-23_Eko-Pol-B.pdf}, volume={23}, number={1}, journal={Wiadomości Ekologiczne}, publisher={Państwowe Wydawnictwo Naukowe}, keywords={aquatic biology, Poland, congresses}, }
