Effects of Salmon Gonadotropin-Releasing Hormone Analog (GnRHa) on Reproductive Success and Egg Size in Rainbow Trout and Brook Trout

Popis výsledku v původním jazyce

Rainbow Trout Oncorhynchus mykiss were treated with a 100- or 25-g/kg dose of salmon gonadotropin-releasing hormone analog (sGnRHa) that was emulsified in Freund's incomplete adjuvant (FIA). Controls were treated with a mixture of FIA and physiological saline. Latency (number of days from the first injection to the date of detected ovulation) was significantly shortened in treated groups compared with the control group. Egg weight, eyeing rate, and hatching rate were significantly reduced in treated groups; mortality after the eyed stage was significantly higher in treated groups. The relationship between latency and the eyeing rate or hatching rate was positive, but the relationship between latency and mortality after the eyed stage was negative. Brook Trout Salvelinus fontinalis were treated with a single injection of sGnRHa-FIA at 12.5g/kg, double acute injections of sGnRHa at 12.5g/kg administered 3 d apart, or a single acute injection of sGnRHa at 50g/kg. Controls were injected wi
