概括

鱼的耐药性和鱼类福利限制了治疗选择. 降低治疗效果显著增加了控制频率和数量,强调了幼虫减少的战略时间.

科学领域:

水产养殖是水产养殖的一种方式.
寄生虫学的寄生虫学
生态生态学生态生态学

背景情况:

鱼 (Lepeophtheirus salmonis) 在养鱼业中构成了重大挑战.
药物耐药性和鱼类福利问题限制了有效的控制策略.
可持续的水产养殖需要管理寄生虫种群,并尽量减少对环境的影响.

研究的目的:

为了建模抗寄生虫治疗效率降低对鱼控制的影响.
在鱼类生产周期内确定高效处理的最佳时间.
评估治疗时间对数量,治疗频率和幼虫产生的影响.

主要方法:

鱼虫种群模型的开发和参数化.
对种群治疗效率降低 (低于50%) 的模拟.
分析治疗时间对总治疗次数的影响,平均数量和幼虫产量.

主要成果:

如果治疗效率低于50%,治疗频率会大大增加,的平均数量也会大大增加.
效率降低会增加不受控制的虫感染的风险.
治疗时间适度影响整体治疗需求和成年雌性子水平.

结论:

有效治疗的战略定时可以显著减少鱼虫幼虫的产量,特别是在春天.
优化治疗时间可以减轻对野生鱼类的影响,而不会影响农场一级的控制.
综合性害虫防治战略对于可持续的鱼养殖至关重要.

Hypothesis: Accept or Fail to Reject?

Hypothesis: Accept or Fail to Reject?

The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...
