Define biocontrol in the context of aquatic pest management.

• A. The use of chemicals to eliminate zero-tolerance species
• B. The use of natural predators or pathogens to suppress pests
• C. The introduction of non-native species to control populations
• D. Using habitat alteration to deter pests

Answer: (B)

In the context of aquatic pest management, biocontrol refers to the use of natural predators or pathogens to suppress pest populations. This method relies on the natural ecological relationships between organisms, where these predators or pathogens can help maintain balance in the ecosystem by controlling the numbers of pest species. For example, introducing a specific fish species that feeds on an invasive aquatic plant can effectively reduce that plant's population and minimize its negative impacts on the ecosystem. Biocontrol is often favored because it can provide a more sustainable and environmentally friendly approach compared to chemical treatments, which may have harmful side effects. Utilizing natural enemies can help in long-term pest management strategies while minimizing the risks associated with synthetic chemicals.
