ABSTRACT. This paper was based on survey data spanning the 1997-2014 period obtained from fisheries enterprises that exploited an average lake surface area of 235,112 ha, which, in the analyses of production parameters, was 86.8% of the total lake surface area exploited for fisheries in Poland. During the period analyzed, the employment of lake fishers declined, which increased the index of lake surface area per fisher, and, in effect, reduced the intensity of fisheries exploitation. The highest value of this parameter was noted in facilities managed by the Polish Angling Association. In 2014, this figure was 1,366 ha per fisher-1, while in cooperative enterprises it was 549 ha per fisher-1. The greater lake surface area per fisher did not result in increased catch effectiveness measured as mean catch size per fisher. This parameter only increased in the case of “other” enterprises represented primarily by national parks.
