What does an acceptable tolerance interval represent?

An acceptable tolerance interval represents a fixed range of values that is determined based on a specific predetermined percentage. In aquatic pest control, this concept is especially important because it provides a guideline for acceptable levels of pests in a given area, helping practitioners understand how many organisms can be present without exceeding acceptable limits. This interval helps ensure that control measures are effective while also maintaining ecological balance.

By defining a fixed range, the tolerance interval allows for variations in factors such as environmental conditions and pest population dynamics, acknowledging that perfect control is often unrealistic. Therefore, when setting or measuring performance criteria, the tolerance interval provides a practical and realistic framework to evaluate success and efficacy in managing aquatic pests.
