Abstract

Age‐composition, size‐distribution, length/weight relationships and growth both in length and weight of bream stocks were studied on fishes collected in NE and SW basins of Lake Balaton during 1982/83. Stocks consisting of 10 to 12 age‐groups were observed at the two lake areas. The linear growth and weight‐gain in the SW‐basin were annually faster than in the NE‐basin, however, the growth of bream in Lake Balaton was slow as compared to that observed 10 years ago. Parallel with progressive eutrophication, the density of bream stocks increased by some 5–10 % especially at hypertrophic lake areas (SW) and consequently their growth was transformed to densitydependent. In the appearance of strong year‐classes some cyclicism could be observed especially in the SW‐basin.
