Which of the following is NOT a method of pestiferous fish control?

• A. Biological control
• B. Chemical control
• C. Environmental monitoring
• D. Mechanical control

Answer: (C)

Environmental monitoring is not a method of pestiferous fish control; instead, it serves as a tool to assess the presence and impact of pests in aquatic environments. While monitoring can provide valuable data about fish populations and ecosystem health, it does not actively manage or control pestiferous fish populations. In contrast, biological control involves using natural predators or competitors to reduce pest fish populations, and chemical control utilizes substances that target these pests directly. Mechanical control refers to methods such as trapping or netting to physically remove pestiferous fish from water bodies. Each of these methods aims to manage or mitigate the impact of pest fish, highlighting the importance of active intervention in controlling aquatic pests, while environmental monitoring plays a supporting role in informing these efforts.
