Abstract Dicentrarchus labrax and Dicentrarchus punctatus is able to thrive and grow in fresh water ponds. In all experiments there was successful controlling of young Tilapia aurea in the experimental ponds in comparison to the control ones. The number of young T. aurea per female and per pond was significantly lower in the experimental ponds than in control ponds. In 1973 the average number of young T. aurea per female was 80 in the experimental ponds and 287 young in the control ponds. In 1974 the average number of T. aurea young per female was 48 in the experimental ponds and 586 young in the control ponds. The growth rate of D. punctatus and D. labrax was higher in fresh water ( S = 0.5‰ ) than in nature (salt water).
