Map of Lake Balaton (Hungary) with indication of its main basins. Location of each recaptured tagged pikeperch is indicated by stocking trials for fish released at Siófok (a), Szemes (b) and Keszthely (c), in autumn and spring, and from shore and offshore. Note that some recaptures located very close to each other, and thus their scores are overlapping on the plot.
