Bonar A., 1993. The use of the catch per unit of effort of seine nets to assess fishery resources in vendace lakes. Acta Ichthyol. Piscat. 23 (1): 99-110.
Analyses of the fishing yield of seines revealed that catches obtained with this gear were predominated by vendace (28%) and roach (45%). Catch of these species per one seine fishing day amounted on the average to 59 and 93 kg respectively. Effectiveness of vendace catches showed positive correlation with stocking rates, and a negative one with the effectiveness of roach catches. High vendace catches were accompanied by relatively lower roach catches. Share of bream in seine catches ranged from 1.5% in Lake Duża Woda to 19% in Lake Jelonek, of whitefish from 0.39% in Lake Jelonek to 16.75% in Lake Żelazne. Share of predators (perch, pike, eel) was from 5.78 to 17.88%.
