Description	Reproduction characteristics and broodstock mortality were compared in farmed perch (FP) and wild perch (WP) under controlled conditions. Thirty-six farmed females (FF) (92.3%) and 30 wild females (WF) (76.9%) spawned during the reproductive season. Absolute fecundity in FF was 18,660 +/- 6,809 eggs per female compared to 31,081 +/- 3,276 eggs per female in WF. Similar differences were observed in relative fecundity (FF 112,470 +/- 13,370 eggs per kg body weight and WF 137,054 +/- 18,513 eggs per kg body weight). No significant differences in fertilization rate (FR), larval resistance (LR) and larval total length (LTL) were found (FR - 91.9 +/- 6.9% and 90.5 +/- 6%; LR - 51.1 +/- 25.2% and 53.5 +/- 26.2%; LTL - 5.88 +/- 0.55 mm and 5.82 +/- 0.51 mm in FP and WP, respectively). The highest differences were found in hatching rates of 27.9 +/- 9.3% in FP and 62.0 +/- 16.0% in WP. No mortalities were observed during the reproductive season, but post-spawning mortality among WP was 92.5 +/- 2.5% of females compared with 21.5 +/- 12.5% in FP. Reproduction characteristics and broodstock mortality were compared in farmed perch (FP) and wild perch (WP) under controlled conditions. Thirty-six farmed females (FF) (92.3%) and 30 wild females (WF) (76.9%) spawned during the reproductive season.
