What type of pesticide would be used if you wanted to eliminate fish that are considered pests?

Piscicides are specifically formulated to target and eliminate fish, making them the appropriate choice when dealing with fish that are considered pests. These pesticides work by interfering with the fish's biological functions, ultimately leading to their death. They are used in various contexts, including controlling invasive fish species in lakes and ponds, managing fish populations in aquaculture, or ensuring public health by reducing fish populations that may carry diseases.

The other types of pesticides mentioned have different target organisms. Predacides are intended for controlling predatory animals, herbicides target weeds and unwanted plants, and miticides are designed to control mites and ticks. Understanding the specific use and target of different pesticide types is critical for effective pest management and environmental safety.
