✦ Synopsis
During a five year study, the size and abundance of zooplankton and 0+ fish in September were registered in a number of Frisian lakes . The mean size of Daphnia was related to the abundance of planktivorous 0+ fish in September. Immigration of fish larvae into the Frisian Lake District from the IJsselmeer in June was observed in 1979 and 1980 . The abundance of 0+ fish was negatively related and the size of Daphnia was positively related to the vulnerability to angling of predatory pikeperch .
