Indicative value of anglers' records for fish assemblage evaluation in a reservoir (Case study Brno reservoir, Czech Republic)
Original language description
The deterioration of water quality in past decades was presented in considerably increasing ratio between non-predatory and predatory fishes biomass in anglers' catches at the Brno Reservoir. In 1991 ? 2007, cyprinids prevailed in anglers´ catches with the mean annual angling effort corresponding 55,063 angling trips (man-day performance). The mean annual angling yield reported in anglers´ records amounted to 32,613 kg (26,236 fish individuals), which corresponds to an individual angling yield of 148 kgper ha. Thus, the yearly angling yield from the Brno reservoir de facto exploits the natural productivity of this type of reservoirs (250 m a.s.l.) which usually corresponds to 150 -200 kg per ha.
