| Description
| - Female northern whitefish were treated with salmon [D-Arg(6)Pro(9)Net]-sGnRHa emulsified in Freund ' s incomplete adjuvant as a sustained release treatment (sGnRHa-FIA) or with [D-Arg(6)Pro(9)Net]-sGnRHa dissolved in physiological saline as acute release treatment (sGnRHa-PS). Females in four experimental groups (A, B, C, D) and one control group (E) were injected intraperitoneally as follows: A and B - sGnRHa-FIA at doses of 50 and 25 mu gkg(-1), respectively; C - double injection (DI) of sGnRHa-PS at 25 mu gkg(-1) administered 3days apart; D - single injection (SI) of sGnRHa-PS at 25 mu gkg(-1); and E - control group receiving a 1:1 mixture of FIA and physiological saline. All treatments induced and synchronized ovulation. Mean time to ovulation was significantly reduced (P{0.05) in GnRHa-treated groups compared with control. Hormone treatments did not affect the relative fecundity. Slight differences were found in ovarian fluid pH between group A and D (P{0.05). Except for group C, egg size was significantly reduced (P{0.01) in hormonally synchronized groups compared with the control. Survival to the eyed stage of eggs from females in groups A, B and C was significantly lower (P{0.01) than in groups D and E. Per cent hatched alevins was lower (P{0.01) in groups A, B and C than in groups D and E. We conclude that synchronization of ovulation in northern whitefish can be induced by a single acute injection of [D-Arg(6)Pro(9)NEt]-sGnRHa at 25 mu gkg(-1) BW if given near the natural spawning time determined by water temperature below 2 degrees C.
