Definition

Fish kills are events where a large number of fish die within a specific area or body of water. These incidents can be caused by various factors such as pollution, disease outbreaks, oxygen depletion, or sudden changes in environmental conditions.

Analogy

Imagine going to a party where everyone suddenly starts feeling sick after eating contaminated food. The sickness spreads quickly among the attendees, causing many people to become ill or even die. Similarly, fish kills occur when a significant number of fish are affected by harmful conditions or contaminants in their environment.
