Kompowski A., 1991. Catches and growth rate of Abramis ballerus (L., 1758) from Lake Dąbie and the Firth of Szczecin. Acta Ichthyol. Piscat. 21 (2): 17-28.
Regular, very intensive fluctuations of the catches of Abramis ballerus occur in 7-8 year cycles. Scale back-calculations (with the method of Rosa Lee) showed that growth of this fish was a little faster in the Firth of Szczecin compared to Lake Dąbie. However, considerable similarity of the parameters in von Bertalanffy′s equation and the distribution of catches suggest that A. ballerus forms a single stock in the two water bodies.
