It has been verified under laboratory conditions that constant and changing water temperature markedly affects the micropopulation growth in Gyrodactylus gobiensis parasite on the body surface of gudgeons (Gobio gobio L.). At a water temperature of 12 degrees C, the number of gyrodactylids gradually increased up to the mean value of 63 specimens per host, which was reached on days 27-28 after experimental infection. At a constant temperature of 18 degrees C, the parasites completely disappeared from the bodies of infected fishes on days 15-20 p.i. A similar effect was produced by gradually increasing temperature from 12 to 18 degrees C, while the decrease in water temperature from 18 to 12 degrees C resulted in an increase in the parasite number.
在实验室条件下已证实,恒定和变化的水温会显著影响 gudgeon(Gobio gobio L.)体表的戈壁三代虫寄生虫的微种群生长。在水温为 12 摄氏度时,三代虫数量逐渐增加,直至实验感染后第 27 - 28 天达到每个宿主平均 63 个标本的数值。在 18 摄氏度的恒定温度下,感染后第 15 - 20 天,寄生虫从受感染鱼的体内完全消失。从 12 摄氏度逐渐升高到 18 摄氏度也产生了类似的效果,而水温从 18 摄氏度降至 12 摄氏度则导致寄生虫数量增加。
