摘要

This study evaluated the use of ovarian fluid turbidity as a potential indicator of landlocked fall ChinookSalmon Oncorhynchus tshawytscha egg survival. A total of 21 females were spawned, with nine of the spawns containingbetween one and ten broken eggs per spawn. Ovarian fluid turbidity ranged from 55.1 to 159 nephelometric turbidity units(NTU), and egg survival to the eyed-stage of egg development ranged from 0 to 68%. There was no significant correlationbetween ovarian fluid turbidity and egg survival. Mean survival of eggs from the spawns containing broken eggs was12.3%, which was significantly lower than the 32.9% mean survival from spawns without broken eggs. These results indicateovarian fluid turbidity cannot be used to predict egg survival in spawns of landlocked fall Chinook Salmon, but thepresence of even a small number of broken eggs may be indicative of poor survival to the eyed-egg stage of development.
