概括

约多消毒有效降低了溪鱼蛋中Carnobacterium maltaromaticum和Vagococcus salmoninarum的流行率. 这种方法显著降低了产卵期间病原体传播的风险.

科学领域:

水生微生物学水生微生物学
鱼类健康管理鱼类健康管理
消毒协议消毒协议

背景情况:

卡诺细菌马尔塔罗马蒂克和Vagococcus salmoninarum是水产养殖中的重要病原体.
溪鱼 (Salvelinus fontinalis) 在产卵期间容易感染细菌感染.
有效的消毒方法对于防止化场疾病传播至关重要.

研究的目的:

评估酸盐消毒在减少C. maltaromaticum和V. salmoninarum在溪鱼蛋中的流行率方面的有效性.
评估这些病原体的卵巢内传播风险.
为了确定鱼蛋的最佳消毒参数.

主要方法:

收集了布克鱼的蛋,并将其分为消毒和未消毒的组.
用100ppm的酸盐进行消毒,持续60分钟 (第一年) 和30分钟 (第二年).
卵子被化,并监测了C. maltaromaticum和V. salmoninarum的细菌生长.

主要成果:

在第一年,没有观察到酸盐消毒卵中的细菌生长.
在第一年,C. maltaromaticum在25%未受精的卵子和53%受精的未被消毒的卵子中被发现.
V. salmoninarum只从未被消毒的受精卵中分离出来;在第二年被消毒的卵中观察到低患病率.

结论:

约多消毒在减少C. maltaromaticum和V. salmoninarum在溪鱼蛋上的流行方面非常有效.
该研究没有发现这些病原体从消毒卵中输入卵巢的证据.
酸盐消毒显著降低了溪养殖中关键细菌病原体的传播风险.

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...
