The effect of selected ovulation-inducing preparations on post-stripping mortality and reproductive indicators of farmed European grayling (Thymallus thymallus L.)
Original language description
An experiment on the effects of hormonal preparations (GonazonTM and Supergestran containing gonadotropin-releasing hormone) on the course of reproduction of farmed grayling (Thymallus thymallus L.) broodstock and their post-stripping mortality was performed at the hatchery in spring 2009. Four-year-old marked grayling females (n = 80) were randomly divided into four groups. The fish were intramuscularly injected with Supergestran at a dose of 30 mýg?kg-1 body weight (Group 1), with GonazonTM at a doseof 30 mýg?kg-1 (Group 2) and with saline 0.9% NaCl (Group 3), while fish of Group 4 were left without treatment (control group). No effect of treatment on the total number of ovulated females (70-80%) was found at the end of the stripping period. Slightly higher (nonsignificant) percentage of ovulated fish in the first stripping time (3 days post injection) was observed in fish treated with Gonazon. The 30-days post-ovulatory mortality remained unaffected by hormone treatments in all gro
