"The goal of this study was to verify, whether all-female perch juveniles grow faster than bisexual ones. Monosex all-female stock (AO) was produced by mating masculinizated females (neomales) with common females of local strain. Bisexual stock (BO) was obtained by routine method. The experiment lasted for 126 days and was preceded by pond-nursed (60 days) and conditioning period (14 days), respectively. Perch were held in 50 l aquaria connected on recirculation system, each group being tested in triplicate. No significant differences (P = 0.0646) in total survival were observed after 126 days of rearing between all-female and bisexual stock, but all-female perch (MO) gained 20 % more weight (P = 0.0480) than the bisexual (BO) (25.2 g ? 9.7 contrary to 21.0 ? 7.5; mean ? S.D.), suggesting that culture of monosex female perch could provide an economic benefit. Overall feed conversion ratio for tanks with mixed sex (1.43 ? 0.21) was significantly (P = 0.0173) higher than in tanks with all-female (1.30 ?" . . .
